and the intended method of distribution. Promptly after receipt of an Underwritten Shelf Takedown Notice (but in any event within two (2) business days), Parent shall give written notice of
the requested Underwritten Shelf Takedown to all other Holders of Registrable Securities and shall include in such Underwritten Shelf Takedown, subject to Section 4, all Registrable Securities that are then covered by the Shelf
Registration Statement and with respect to which Parent has received a written request for inclusion therein from a Holder no later than five (5) business days after the date of Parent’s notice. Parent shall not be required to facilitate
an Underwritten Shelf Takedown (i) unless the Aggregate Offering Price from such offering is at least $30,000,000, (ii) more than two (2) times in the aggregate in any 12-month period for each of (x) the TD Stockholders and their
Stockholder Transferees, collectively, (y) the Ricketts Stockholders and their Stockholder Transferees, collectively, and (z) the Riney Parties, collectively, or (iii) within sixty (60) days following any previous underwritten
offering in which at least seventy-five percent (75%) of the number of Registrable Securities requested by the Holders to be included in such Registration Statement were included and sold. 

(f) Selection of Underwriters. The Initiating Holder of an Underwritten Shelf Takedown shall have the right to select the investment
banking firm(s) and manager(s) to administer such Underwritten Shelf Takedown (including which such underwriters will serve as lead or co-lead), subject to the approval of Parent (which approval shall not be unreasonably withheld, conditioned or
delayed). 
 Section 3. Demand Registrations. 

(a) Right to Demand Registrations. If, at any time after the date hereof Parent is not eligible under applicable Law to register
Registrable Securities by way of a Registration Statement on Form S-3 pursuant to Section 2, a Holder may, by providing written notice to Parent, request to sell all or part of its Registrable Securities pursuant to a Registration Statement
separate from a Shelf Registration Statement (a “Demand Registration”); provided that (x) for so long as the Riney Stockholder holds 50% or more of the aggregate Registrable Securities held collectively by the Riney
Parties, any such written notice delivered by a Holder that is a Riney Party shall only be valid if delivered by the Riney Stockholder and (y) if the Riney Stockholder holds less than 50% of the Registrable Securities held collectively by the
Riney Parties, then the Riney Parties may deliver such written notice with the consent of Riney Parties holding a majority of the Registrable Securities held collectively by the Riney Parties. Each request for a Demand Registration (a
“Demand Registration Request”) shall specify the number of Registrable Securities intended to be offered and sold by such Holder pursuant to the Demand Registration and the intended method of distribution thereof, including whether
it is intended to be an underwritten offering. Promptly (but in any event within three (3) business days) after receipt of a Demand Registration Request, Parent shall give written notice of the Demand Registration Request to all other Holders
of Registrable Securities. As promptly as practicable after receipt of a Demand Registration Request, Parent shall register all Registrable Securities (i) that have been requested to be registered in the Demand Registration Request and
(ii) subject to Section 4, with respect to which Parent has received a written request for inclusion in the Demand Registration from a Holder no later than fifteen (15) days after the date on which notice was given to Holders
of the Demand Registration Request. Parent shall use its best efforts to cause the Registration Statement filed pursuant to this Section 3(a) to be declared effective by the SEC or otherwise become effective under the Securities Act as
promptly as practicable after the filing thereof. A 

  
 -8- 

 
Demand Registration shall be effected by way of a Registration Statement on Form S-3 or any similar short-form registration statement to the extent Parent is permitted to use such form at such
time. Parent shall not be required to effect a Demand Registration (i) unless the Demand Registration includes Registrable Securities in an amount not less than the Minimum Amount or (ii) within sixty (60) days following the effective
date of a Registration Statement relating to a previous Demand Registration. 
 (b) Number of Demand Registrations. Each of
(x) the TD Stockholders and their Stockholder Transferees, collectively, (y) the Ricketts Stockholders and their Stockholder Transferees, collectively, and (z) the Riney Parties, collectively, shall be entitled to request up to two
(2) Demand Registrations in the aggregate (which, for the avoidance of doubt, shall be in addition to any Shelf Registration pursuant to Section 2, other than any Underwritten Shelf Takedown, which shall be deemed a Demand Registration for
these purposes and count towards such maximum number of Demand Registrations) during any 12-month period. 
 (c) Withdrawal. A Holder
may, by written notice to Parent, withdraw its Registrable Securities from a Demand Registration at any time prior to the effectiveness of the applicable Registration Statement. Upon receipt of notices from all applicable Holders to such effect, or
if such withdrawal shall reduce the Aggregate Offering Price for the offering of the Registrable Securities to be registered in connection with such Demand Registration below the Minimum Amount, Parent shall cease all efforts to seek effectiveness
of the applicable Registration Statement, unless Parent intends to effect a primary offering of securities pursuant to such Registration Statement. In the event that all applicable Holders withdraw their Registrable Securities from a Demand
Registration and the withdrawal is a Permissible Withdrawal, such Demand Registration Request shall not count against the limitation on the number of such Holder’s Demand Registrations set forth in Section 3(b). 

(d) Selection of Underwriters. If a Demand Registration is an underwritten offering, the Initiating Holder shall have the right to
select the investment banking firm(s) to act as the managing underwriter(s) in connection with such offering (including which such managing underwriters will serve as lead or co-lead), subject to the approval of Parent (which approval shall not be
unreasonably withheld, conditioned or delayed). 
 Section 4. Inclusion of Other Securities; Priority. Parent shall not include
in any Demand Registration or Shelf Takedown any securities that are not Registrable Securities without the prior written consent of the Holder(s) of the Registrable Securities participating in such Demand Registration or Shelf Takedown. If a Demand
Registration or Shelf Takedown involves an underwritten offering and the managing underwriters of such offering advise Parent and the Holders in writing that, in their opinion, the number of Equity Securities proposed to be included in such Demand
Registration or Underwritten Shelf Takedown, including all Registrable Securities and all other Equity Securities proposed to be included in such offering, exceeds the number of Equity Securities that can reasonably be expected to be sold in such
offering without adversely affecting the success of the offering (including the price, timing or distribution of the securities to be sold in such offering), Parent shall include in such Demand Registration or Underwritten Shelf Takedown:
(i) first, the Registrable Securities proposed to be sold by the Initiating Holder; (ii) second, the Registrable Securities proposed to be sold by the Participating Holders; and (iii) third, any Equity Securities
proposed to be included therein by 

  
 -9- 

 
any other Persons (including Equity Securities to be sold for the account of Parent and/or any other holders of Equity Securities), allocated, in the case of this clause (iii), among such Persons
in such manner as Parent may determine. If more than one Participating Holder is participating in such Demand Registration or Underwritten Shelf Takedown and the managing underwriters of such offering determine that a limited number of Registrable
Securities may be included in such offering without reasonably being expected to adversely affect the success of the offering (including the price, timing or distribution of the securities to be sold in such offering), then the Registrable
Securities that are included in such offering shall be allocated pro rata among the Participating Holders on the basis of the number of Registrable Securities initially requested to be sold by each such Participating Holder in such offering. 

Section 5. Piggyback Registrations. 

(a) Whenever Parent proposes to register any Equity Securities under the Securities Act (other than a registration (i) pursuant to a
Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to employees or directors of Parent pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration
Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii) in connection with any dividend or distribution reinvestment or similar plan or
(iv) that is a Demand Registration or Shelf Takedown hereunder), whether for its own account or for the account of one or more stockholders of Parent (other than the Holders of Registrable Securities) (a “Piggyback
Registration”), Parent shall give prompt written notice to each Holder of Registrable Securities of its intention to effect such a registration (but in no event less than twenty (20) days prior to the proposed date of filing of the
applicable Registration Statement) and, subject to Sections 5(b) and 5(c), shall include in such Registration Statement and in any offering of Equity Securities to be made pursuant to such Registration Statement that number of
Registrable Securities requested to be sold in such offering by such Holder for the account of such Holder, provided that Parent has received a written request for inclusion therein from such Holder no later than fifteen (15) days after
the date on which Parent has given notice of the Piggyback Registration to Holders. Parent may terminate or withdraw a Piggyback Registration prior to the effectiveness of such registration at any time in its sole discretion, subject to any other
contractual obligations between Parent and any other holders of Equity Securities with respect to such Piggyback Registration. If a Piggyback Registration is effected pursuant to a Registration Statement on Form S-3 or the then appropriate form for
an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor rule thereto (a “Piggyback Shelf Registration Statement”), the Holders of Registrable Securities shall be
notified by Parent of and shall have the right, but not the obligation, to participate in any offering pursuant to such Piggyback Shelf Registration Statement (a “Piggyback Shelf Takedown”), subject to the same limitations that are
applicable to any other Piggyback Registration as set forth above. A Holder may, by written notice to Parent, withdraw its Registrable Securities from a Piggyback Registration at any time prior to the effectiveness of the applicable Registration
Statement. 
 (b) Priority on Primary Piggyback Registrations. If a Piggyback Registration or Piggyback Shelf Takedown is initiated
as a primary underwritten offering on behalf of Parent and the managing underwriters of the offering advise Parent in writing that, in their opinion, the number of Equity Securities proposed to be included in such offering, including all Registrable

  
 -10- 

 
Securities and all other Equity Securities proposed to be included in such offering, exceeds the number of Equity Securities that can reasonably be expected to be sold in such offering without
adversely affecting the success of the offering (including the price, timing or distribution of the securities to be sold in such offering), Parent shall include in such Piggyback Registration or Piggyback Shelf Takedown: (i) first, the
Equity Securities that Parent proposes to sell in such offering; (ii) second, any Registrable Securities requested to be included therein by any Holders, allocated, in the case of this clause (ii), pro rata among such Holders on the
basis of the number of Registrable Securities initially proposed to be included by each such Holder in such offering, up to the number of Registrable Securities, if any, that the managing underwriters determine can be included in the offering
without reasonably being expected to adversely affect the success of the offering (including the price, timing or distribution of the securities to be offered in such offering); and (iii) third, any Equity Securities proposed to be
included in such offering by any other Person to whom Parent has a contractual obligation to facilitate such offering, allocated, in the case of this clause (iii), pro rata among such Persons on the basis of the number of Equity Securities initially
proposed to be included by each such Person in such offering, up to the number of Equity Securities, if any, that the managing underwriters determine can be included in the offering without reasonably being expected to adversely affect the success
of the offering (including the price, timing or distribution of the securities to be offered in such offering). 
 (c) Priority on
Secondary Piggyback Registrations. If a Piggyback Registration or a Piggyback Shelf Takedown is initiated as an underwritten offering on behalf of a holder of Equity Securities to whom Parent has a contractual obligation to facilitate such
offering, other than Holders of Registrable Securities, and the managing underwriters of the offering advise Parent in writing that, in their opinion, the number of Equity Securities proposed to be included in such offering, including all
Registrable Securities and all other Equity Securities requested to be included in such offering, exceeds the number of Equity Securities which can reasonably be expected to be sold in such offering without adversely affecting the success of the
offering (including the price, timing or distribution of the securities to be sold in such offering), Parent shall include in such Piggyback Registration or Piggyback Shelf Takedown: (i) first, the Equity Securities that the Person
demanding the offering pursuant to such contractual right proposes to sell in such offering; (ii) second, any Registrable Securities requested to be included therein by any Holders, allocated, in the case of this clause (ii), pro rata
among such Holders on the basis of the number of Registrable Securities initially proposed to be included by each such Holder in such offering, up to the number of Registrable Securities, if any, that the managing underwriters determine can be
included in the offering without reasonably being expected to adversely affect the success of the offering (including the price, timing or distribution of the securities to be offered in such offering); and (iii) third, any Equity
Securities proposed to be sold for the account of Parent in such offering and any Equity Securities proposed to be included in such offering by any other Person to whom Parent has a contractual obligation to facilitate such offering, allocated, in
the case of this clause (iii), pro rata among Parent and such Persons on the basis of the number of Equity Securities initially proposed to be included by Parent and each such other Person in such offering, up to the number of Equity Securities, if
any, that the managing underwriters determine can be included in the offering without reasonably being expected to adversely affect the success of the offering (including the price, timing or distribution of the securities to be offered in such
offering).

 (d) Selection of Underwriters. If a Piggyback Registration or Piggyback Shelf Takedown is
initiated as a primary underwritten offering on behalf of Parent, Parent shall have the right to select the investment banking firm(s) to act as the managing underwriter(s) in connection with such offering. If a Piggyback Registration or a Piggyback
Shelf Takedown is initiated as an underwritten offering on behalf of a holder of Equity Securities to whom Parent has a contractual obligation to facilitate such offering, the right to select the investment banking firm(s) to act as the managing
underwriter(s) in connection with such offering shall be governed by such applicable contractual arrangement between Parent and such holder of Equity Securities, provided that such managing underwriter shall be reasonably acceptable to the
Holder or Holders of a majority of the Registrable Securities proposed to be included in such Piggyback Registration or Piggyback Shelf Takedown (such approval not to be unreasonably withheld, conditioned or delayed); provided,
further, that such Holder or Holders may designate a co-managing underwriter to participate in the Piggyback Registration or Piggyback Shelf Takedown, in each case to the extent permitted by such applicable contractual arrangement between
Parent and such holder of Equity Securities. 
 Section 6. Holdback Agreements. 

(a) Holders of Registrable Securities. Each Initiating Holder and Participating Holder, and each other Holder of Registrable Securities
that holds or beneficially owns at least 2% of the outstanding Common Stock agrees that in connection with any underwritten Demand Registration of Common Stock, Underwritten Shelf Takedown or a registered underwritten offering of Common Stock by
Parent in a primary offering for its own account, and upon written request from the managing underwriter(s) for such offering, such Holder shall not, without the prior written consent of such managing underwriter(s), during such period as is
reasonably requested by the managing underwriter(s) (which period shall in no event be longer than seven (7) days prior to and sixty (60) days after the pricing of such offering), effect any public sale or distribution of any Similar
Securities to those being registered, including any sale under Rule 144. The foregoing provisions of this Section 6(a) shall not apply to offers or sales of Registrable Securities that are included in an offering pursuant to
Section 2, Section 3, or Section 5 of this Agreement and shall be applicable to the Holders of Registrable Securities only if, for so long as and to the extent that Parent, the directors and executive officers of
Parent, and each selling stockholder included in such offering are subject to the same restrictions if requested by the managing underwriter(s) for such offering, and Parent uses its reasonable best efforts to ensure that each other holder of at
least 5% of the outstanding Common Stock is subject to the same restrictions if requested by the managing underwriter(s) for such offering. Each Holder of Registrable Securities agrees to execute and deliver such other agreements as may be
reasonably requested by the managing underwriter(s) that are consistent with the foregoing provisions of this Section 6(a) and are necessary to give further effect thereto. Any discretionary waiver or termination of the requirements
under the foregoing provisions made by Parent or the applicable managing underwriter(s) shall apply to each Holder of Registrable Securities proposed to be sold in such offering on a pro rata basis. Without limiting the foregoing (but subject to
Section 13(a)), if after the date hereof Parent grants any Person (other than a Holder of Registrable Securities) any rights to demand or participate in a registration, Parent agrees that it shall include in such Person’s agreement
a covenant consistent with the foregoing provisions of this Section 6(a). 

  
 -12- 

 (b) Parent. To the extent requested by the managing underwriter(s) for the applicable
offering, Parent shall not effect any sale registered under the Securities Act or other public distribution of Equity Securities for its own account during the period commencing seven (7) days prior to and ending sixty (60) days after the
pricing of an underwritten offering pursuant to Section 2, Section 3, or Section 5 of this Agreement, other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration
solely relating to an offering or sale to employees or directors of Parent pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a
transaction subject to Rule 145 under the Securities Act or any successor rule thereto) or (iii) in connection with any dividend or distribution reinvestment or similar plan. 

Section 7. Suspensions. Upon giving prompt written notice to the Holders of Registrable Securities, Parent shall be entitled to
delay or suspend the filing, effectiveness or use of a Registration Statement or Prospectus (a “Suspension”) if the Board of Directors of Parent determines in good faith (after consultation with external legal counsel) that
proceeding with the filing, effectiveness or use of such Registration Statement or Prospectus would require Parent to publicly disclose material non-public information in such Registration Statement or Prospectus so that it would not be materially
misleading, the disclosure of which (i) would not be required to be made at such time but for the filing, effectiveness or use of such Registration Statement or Prospectus and (ii) would, in the good faith judgment of Parent’s Board
of Directors, have a material adverse effect on Parent or on any pending negotiation or plan of Parent to effect a merger, acquisition, disposition, financing, reorganization, recapitalization or other similar transaction; provided, that
Parent shall not be entitled to exercise a Suspension (i) more than twice during any 12-month period, (ii) for a period exceeding thirty (30) days on any one occasion, or (iii) for a period exceeding sixty (60) days during
any 12-month period. Each Holder who is notified by Parent of a Suspension pursuant to this Section 7 shall keep the existence of such Suspension confidential and shall immediately discontinue (and direct any other Person making offers
or sales of Registrable Securities on behalf of such Holder to immediately discontinue) offers and sales of Registrable Securities pursuant to such Registration Statement or Prospectus and any other use of such Registration Statement or Prospectus
until such time as it is advised in writing by Parent that the use of the Registration Statement or Prospectus may be resumed and, if applicable, is furnished by Parent with a supplemented or amended Prospectus as contemplated by
Section 8(g). If Parent delays or suspends a Demand Registration, the Initiating Holder of such Demand Registration shall be entitled to withdraw its Demand Registration Request and, if it does so, such Demand Registration Request shall
not count against the limitation on the number of such Initiating Holder’s Demand Registrations set forth in Section 3(b). Parent shall promptly notify the Holders of the expiration of any period during which it exercised its rights
under this Section. Parent agrees that, in the event it exercises its rights under this Section, it shall, within thirty (30) days following the Holders’ receipt of the notice of suspension, update the suspended Registration Statement as
may be necessary to permit the Holders to resume use thereof in connection with the offer and sale of their Registrable Securities in accordance with applicable law.

 Section 8. Registration Procedures . If and whenever Parent is required to effect the
registration of any Registrable Securities pursuant to this Agreement, Parent shall use its best efforts to effect and facilitate the registration, offering and sale of such Registrable Securities in accordance with the intended method of
disposition thereof as promptly as is practicable and, pursuant thereto, Parent shall as expeditiously as possible and as applicable: 
 (a)
prepare and file with the SEC a Registration Statement with respect to such Registrable Securities, make all required filings required in connection therewith and (if the Registration Statement is not automatically effective upon filing) use its
reasonable best efforts to cause such Registration Statement to become effective as promptly as practicable; provided that before filing a Registration Statement or any amendments or supplements thereto, Parent shall furnish to counsel to the
Holders for such registration copies of all documents proposed to be filed, which documents shall be subject to review by counsel to the Holders, and give the Holders participating in such registration an opportunity to comment on such documents and
keep such Holders reasonably informed as to the registration process; 
 (b) prepare and file with the SEC such amendments and supplements
to any Registration Statement and the Prospectus used in connection therewith as may be (i) reasonably requested by any selling Holder (to the extent such request relates to information relating to such Holder), or (ii) necessary to keep
such Registration Statement effective until all of the Registrable Securities covered by such Registration Statement have been disposed of and comply with the applicable requirements of the Securities Act with respect to the disposition of the
Registrable Securities covered by such Registration Statement; 
 (c) before filing a Registration Statement or Prospectus, or any
amendments or supplements thereto and in connection therewith, furnish to the managing underwriter or underwriters, if any, and to each Holder participating in the registration, without charge, such number of copies of the Prospectus included in
such Registration Statement (including each preliminary Prospectus) and any supplement thereto (in each case including all exhibits thereto and all documents incorporated by reference therein) and such other documents as such Holder may reasonably
request, including in order to facilitate the disposition of the Registrable Securities owned by such Holder, which documents will be subject to the review of such underwriters and such Holders and their respective counsel, and not file any
Registration Statement or Prospectus or amendments or supplements thereto to which the Holders covered by the same or the underwriter or underwriters, if any, shall reasonably object; 

(d) use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky Laws of such
U.S. jurisdiction(s) as any Holder participating in the registration or any managing underwriter reasonably requests and do any and all other acts and things that may be necessary or reasonably advisable to enable such Holder and each underwriter,
if any, to consummate the disposition of such Holder’s Registrable Securities in such jurisdiction(s); provided, that Parent shall not be required to qualify generally to do business, subject itself to taxation or consent or subject
itself to general service of process in any jurisdiction where it would not otherwise be required to do so but for its obligations pursuant to this Section 8(d); 

(e) use its reasonable best efforts to cause all Registrable Securities covered by any Registration Statement to be registered with or
approved by such other Governmental Entities or self-regulatory bodies as may be necessary or reasonably advisable in light of the business and operations of Parent to enable each Holder participating in the registration to consummate the

  
 -14- 

 
disposition of such Registrable Securities in accordance with the intended method or methods of disposition thereof; provided, that Parent shall not be required to qualify generally to do
business, subject itself to taxation or consent or subject itself to general service of process in any jurisdiction where it would not otherwise be required to do so but for its obligations pursuant to this Section 8(e); 

(f) promptly notify each Holder participating in the registration and the managing underwriters of any underwritten offering: 

(i) each time when the Registration Statement, any pre-effective amendment thereto, the Prospectus or any Prospectus
supplement or any post-effective amendment to the Registration Statement has been filed and, with respect to the Registration Statement or any post-effective amendment thereto, when the same has become effective; 

(ii) of any oral or written comments by the SEC or of any request by the SEC or any other federal or state governmental
authority for amendments or supplements to the Registration Statement or the Prospectus or for any additional information regarding such Holder; 

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or the
initiation or threatening of any proceedings for any such purpose; and 
 (iv) of the receipt by Parent of any notification
with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky Laws of any jurisdiction; 

(g) notify each Holder participating in such registration, at any time when a Prospectus relating thereto is required to be delivered under
the Securities Act, upon becoming aware of the occurrence of any event that would cause the Prospectus included in such Registration Statement to contain an untrue statement of a material fact or to omit any fact necessary to make the statements
made therein not misleading in light of the circumstances under which they were made, and, as promptly as practicable, prepare, file with the SEC and furnish to such Holder a reasonable number of copies of a supplement or amendment to such
Prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus will not contain any untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading
in light of the circumstances under which they were made; 
 (h) in the event of the issuance of any stop order suspending the effectiveness
of a Registration Statement, any order suspending or preventing the use of any related Prospectus or any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, use its best efforts
to promptly obtain the withdrawal or lifting of any such order or suspension; 
 (i) not file or make any amendment to any Registration
Statement with respect to any Registrable Securities, or any amendment of or supplement to the Prospectus used in connection therewith, that refers to any Holder covered thereby by name or otherwise identifies such Holder as the holder of any
securities of Parent without the consent of such Holder (such consent not to 

  
 -15- 

 
be unreasonably withheld or delayed), unless and to the extent such disclosure is required by Law; provided, that (i) each Holder shall furnish to Parent in writing such information
regarding itself and the distribution proposed by it as Parent may reasonably request for use in connection with a Registration Statement or Prospectus and (ii) each Holder agrees to notify Parent as promptly as practicable of any inaccuracy or
change in information previously furnished to Parent by such Holder (including with respect to any inaccuracy in any representations or warranties made by such Holder in any underwriting agreement) or of the occurrence of any event that would cause
the Registration Statement or the Prospectus included in such Registration Statement to contain an untrue statement of a material fact regarding such Holder or the distribution of such Registrable Securities or to omit to state any material fact
regarding such Holder or the distribution of such Registrable Securities required to be stated therein or necessary to make the statements made therein not misleading in light of the circumstances under which they were made and to furnish to Parent,
as promptly as practicable, any additional information required to correct and update the information previously furnished by such Holder such that such Registration Statement and Prospectus shall not contain any untrue statement of a material fact
regarding such Holder or the distribution of such Registrable Securities or omit to state a material fact regarding such Holder or the distribution of such Registrable Securities necessary to make the statements therein not misleading in light of
the circumstances under which they were made; 
 (j) cause such Registrable Securities to be listed on each securities exchange on which the
Common Stock is then listed or, if the Common Stock is not then listed on any securities exchange, use its reasonable best efforts to cause such Registrable Securities to be listed on a national securities exchange selected by Parent after
consultation with the Holders participating in such registration; 
 (k) provide a transfer agent and registrar (which may be the same
entity) for all such Registrable Securities not later than the effective date of such Registration Statement; 
 (l) make available for
inspection by any Holder participating in the registration, upon reasonable notice at reasonable times and for reasonable periods, any underwriter participating in any underwritten offering pursuant to such Registration Statement and any attorney,
accountant or other agent retained by any such Holder or underwriter, all corporate documents, financial and other records relating to Parent and its business reasonably requested by such Holder or underwriter, cause Parent’s officers,
directors, employees and independent accountants to supply all information reasonably requested by any such Holder, underwriter, attorney, accountant or agent in connection with such registration or offering and make senior management of Parent and
Parent’s independent accountants available for customary due diligence and drafting sessions; provided, that any Person gaining access to information or personnel of Parent pursuant to this Section 8(l) shall
(i) reasonably cooperate with Parent to limit any resulting disruption to Parent’s business and (ii) protect the confidentiality of any information regarding Parent which Parent determines in good faith to be confidential and of which
determination such Person is notified, pursuant to customary confidentiality agreements reasonably acceptable to Parent; 
 (m) otherwise
use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its stockholders, as soon as reasonably practicable, an earnings statement (in a form that satisfies the provisions of
Section 11(a) of the Securities 

  
 -16- 

 
Act and Rule 158 under the Securities Act or any successor rule thereto) covering the period of at least 12 months beginning with the first day of Parent’s first full fiscal quarter after
the effective date of the applicable Registration Statement, which requirement shall be deemed satisfied if Parent timely files complete and accurate information on Forms 10-K, 10-Q and 8-K under the Exchange Act and otherwise complies with Rule 158
under the Securities Act or any successor rule thereto; 
 (n) in the case of an underwritten offering of Registrable Securities, promptly
incorporate in a supplement to the Prospectus or a post-effective amendment to the Registration Statement such information as is reasonably requested by the managing underwriter(s) or any Holder participating in such underwritten offering to be
included therein, the purchase price for the securities to be paid by the underwriters and any other applicable terms of such underwritten offering (and the Holders shall promptly supply any such information within their possession), and promptly
make all required filings of such supplement or post-effective amendment; 
 (o) in the case of an underwritten offering of Registrable
Securities, enter into such customary agreements (including underwriting and lock-up agreements in customary form) and take all such other customary actions as any Holder participating in such offering or the managing underwriter(s) of such offering
reasonably requests in order to expedite or facilitate the disposition of such Registrable Securities; 
 (p) in the case of an underwritten
offering of Registrable Securities, furnish to each underwriter, if any, participating in an offering of Registrable Securities (i) (A) all legal opinions of outside counsel to Parent required to be included in the Registration Statement
and (B) a written legal opinion of outside counsel to Parent, dated the closing date of the offering, in form and substance as is customarily given in opinions of outside counsel to Parent to underwriters in underwritten registered offerings;
and (ii) (A) obtain all consents of independent public accountants required to be included in the Registration Statement and (B) on the date of the execution of the applicable underwriting agreement and at the closing of the offering,
dated the respective dates of delivery thereof, a “comfort letter” signed by Parent’s independent public accountants in form and substance as is customarily given in accountants’ letters to underwriters in underwritten registered
offerings; 
 (q) in the case of an underwritten offering of Registrable Securities, make senior management of Parent available, to the
extent requested by the managing underwriter(s), to assist in the marketing of the Registrable Securities to be sold in such underwritten offering, including the participation of such members of senior management of Parent in “road show”
presentations and other customary marketing activities, including “one-on-one” meetings with prospective purchasers of the Registrable Securities to be sold in such underwritten offering (with an understanding that these shall be scheduled
in a collaborative manner so as not to unreasonably interfere with the conduct of business of Parent), and otherwise facilitate, cooperate with, and participate in such underwritten offering and customary selling efforts related thereto, in each
case to the same extent as if Parent were engaged in a primary underwritten registered offering of its Common Stock; 

  
 -17- 

 (r) cooperate with the Holders of the Registrable Securities to facilitate the timely preparation
and delivery of certificates representing the Registrable Securities to be sold pursuant to such Registration Statement free of any restrictive legends and representing such number of shares of Common Stock and registered in such names as the
Holders of the Registrable Securities may reasonably request a reasonable period of time prior to sales of Registrable Securities pursuant to such Registration Statement; provided, that Parent may satisfy its obligations hereunder without
issuing physical stock certificates through the use of The Depository Trust Company’s Direct Registration System; 
 (s) not later than
the effective date of such Registration Statement, provide a CUSIP number for all Registrable Securities covered thereby and provide the applicable transfer agent with printed certificates for the Registrable Securities in a form eligible for
deposit with The Depository Trust Company; provided, that Parent may satisfy its obligations hereunder without issuing physical stock certificates through the use of The Depository Trust Company’s Direct Registration System; 

(t) upon the request of any Holder, promptly amend any Shelf Registration Statement or take such other action as may be necessary to

(u) otherwise use its reasonable best efforts to take or cause to be taken all other actions necessary or reasonably advisable to effect the
registration, marketing and sale of such Registrable Securities contemplated by this Agreement. 
 Each Holder agrees that upon receipt of
any notice from Parent of the happening of any event of the kind described in Section 8(g) or Section 8(h), such Holder shall use its best efforts to discontinue (and direct any other Person making offers or sales of
Registrable Securities on behalf of such Holder to discontinue) offers and sales of Registrable Securities pursuant to such Registration Statement or Prospectus and any other use of such Registration Statement or Prospectus until such time as it is
advised in writing by Parent that the use of the Registration Statement or Prospectus may be resumed. If Parent gives any such notice in respect of a Demand Registration, the Initiating Holder shall be entitled to withdraw its Demand Registration
Request and, if it does so, such Demand Registration Request shall not count against the limitation on the number of such Initiating Holder’s Demand Registrations set forth in Section 3(b). 

Section 9. Participation in Underwritten Offerings. No Person may participate in any underwritten offering pursuant to this
Agreement unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements in customary form approved by the Persons entitled under this Agreement to approve such arrangements (which
shall contain such terms and conditions as are generally prevailing in agreements of that type, including indemnities no more burdensome to the indemnifying party and no less favorable to the recipient thereof than those provided in
Section 11 hereof) 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;
provided, that no Holder of Registrable Securities included in any underwritten offering hereunder shall be required to make any representations or warranties to Parent or the underwriters (other than representations and warranties regarding
(A) such Holder’s identity and ownership of its Registrable Securities 

  
 -18- 

 
to be sold in such offering, (B) such Holder’s power and authority to effect such Transfer, (C) such Holder’s intended method of disposition, (D) information furnished by
such Holder expressly for inclusion in any Registration Statement or Prospectus, and (E) such matters pertaining to such Holder’s compliance with securities Laws as may be reasonably requested by the managing underwriter(s)) or to
undertake any indemnification obligations to Parent or the underwriters with respect thereto, other than indemnities that are no more burdensome to the indemnifying party and no less favorable to the recipient thereof than those provided in
Section 11 hereof. 
 Section 10. Registration Expenses. 

(a) Parent shall pay directly or promptly reimburse all costs, fees and expenses (other than Selling Expenses) incident to Parent’s
performance of or compliance with this Agreement in connection with the registration of Registrable Securities, including, without limitation, (i) all SEC, FINRA and other registration and filing fees; (ii) all fees and expenses associated
with filings to be made with, or the listing of any Registrable Securities on, any securities exchange or over-the-counter trading market on which the Registrable Securities are to be listed or quoted; (iii) all fees and expenses of complying
with securities and blue sky Laws (including reasonable fees and disbursements of one counsel in connection therewith); (iv) all printing, messenger, telephone and delivery expenses (including the cost of distributing Prospectuses in

agent’s and registrar’s fees; (vii) all fees and expenses of counsel to Parent; and (viii) all fees and expenses of Parent’s independent public accountants (including any fees and expenses arising from any special audits or
“comfort letters”) and any other Persons retained by Parent (for the avoidance of doubt, excluding underwriters) in connection with or incident to any registration of Registrable Securities pursuant to this Agreement (all such costs, fees
and expenses, “Registration Expenses”). Parent shall pay the reasonable fees and expenses of one counsel engaged by the Holders of a majority of the Registrable Securities being registered; provided that, in the event that
both (i) TD, TD Lux and/or their Stockholder Transferees and (ii) any Riney Party(ies) participate in an offering, Parent shall pay the reasonable fees and expenses of one counsel engaged by each of (i) TD, TD Lux and/or their
Stockholder Transferees (collectively), as applicable, and (ii) such Riney Party(ies) (collectively), up to a maximum aggregate amount of $200,000 per offering. Each Holder shall bear its respective Selling Expenses associated with a registered
sale of its Registrable Securities pursuant to this Agreement. For the avoidance of doubt, neither Registration Expenses nor Selling Expenses shall include the fees or expenses of any underwriters’ counsel. 

(b) The obligation of Parent to bear and pay the Registration Expenses shall apply irrespective of whether a registration, once properly
demanded or requested, becomes effective or is withdrawn or suspended; provided, that the Registration Expenses for any Registration Statement withdrawn at the request of one or more Holder(s) (unless withdrawn following commencement of a
Suspension) shall be borne by such Holder(s). 

  
 -19- 

 Section 11. Indemnification; Contribution. 

(a) Parent shall, to the fullest extent permitted by Law, indemnify and hold harmless each Holder of Registrable Securities, any Person who is
a “controlling person” of such Holder or any of its subsidiaries within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such Person, a “Controlling Person”), their
respective direct and indirect general and limited partners, advisory board members, directors, officers, trustees, managers, members, employees, agents, Affiliates and shareholders, and each other agent, if any, who acts on behalf of or controls
any such Holder or Controlling Person (each of the foregoing, a “Covered Person”) against any losses, claims, actions, damages, liabilities (or actions or proceedings in respect thereof, whether or not such Covered Person is a party
thereto) and expenses (including reasonable costs of investigation and legal expenses), joint or several, to which such Covered Person may become subject under the Securities Act, the Exchange Act, any state blue sky securities Laws, any equivalent
non-U.S. securities Laws or otherwise, insofar as such losses, claims, actions, damages, liabilities or expenses arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in or incorporated by
reference in any Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule thereto) (a “Free Writing Prospectus”) or any amendment
thereof or supplement thereto or any document incorporated by reference therein or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and Parent
shall reimburse each Covered Person for any legal or other expenses reasonably incurred by such Covered Person in connection with investigating, defending or settling any such loss, claim, action, damage or liability; provided, that Parent
shall not be so liable in any such case to the extent that any loss, claim, action, damage, liability or expense arises out of or is based upon any such untrue statement or alleged untrue statement, or omission or alleged omission, made or
incorporated by reference in any such Registration Statement, Prospectus, preliminary Prospectus, Free Writing Prospectus or any amendment thereof or supplement thereto or any document incorporated by reference therein in reliance upon, and in
conformity with, written information prepared and furnished to Parent by such Covered Person expressly for use therein or arises out of or based upon such Covered Person’s failure to deliver a copy of the Prospectus or any amendments or
supplements thereto to a purchaser (if so required) after Parent has furnished such Covered Person with a sufficient number of copies of the same. This indemnity shall be in addition to any liability Parent may otherwise have. 

(b) In connection with any registration in which a Holder of Registrable Securities is participating, each such Holder shall (severally and
not jointly), to the fullest extent permitted by Law, indemnify and hold harmless Parent, its directors and officers, employees, agents and any Person who is a Controlling Person of Parent and any other selling Holder of Registrable Securities, its
directors and officers, employees, agents and any Person who is a Controlling Person of such other selling Holder against any losses, claims, actions, damages, liabilities (or actions or proceedings in respect thereof, whether or not such Covered
Person is a party thereto) and expenses (including reasonable costs of investigation and legal expenses), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act, any state blue sky securities
Laws, any equivalent non-U.S. securities Laws or otherwise, insofar as such losses, claims, actions, damages, liabilities or expenses arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, 

  
 -20- 

 
Prospectus, preliminary Prospectus, Free Writing Prospectus or any amendment thereof or supplement thereto or any document incorporated by reference therein or (ii) any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but, in the case of each of clauses (i) and (ii) solely to the extent that such untrue statement or alleged untrue
statement, or omission or alleged omission, is made in such Registration Statement, Prospectus, preliminary Prospectus, Free Writing Prospectus or any amendment thereof or supplement thereto or any document incorporated by reference therein in
reliance upon, and in conformity with, written information regarding such Holder prepared and furnished to Parent by such Holder expressly for use therein; provided, that the obligation to indemnify pursuant to this Section 11(a)
shall be individual and several, not joint and several, for each participating Holder and shall not exceed an amount equal to the net proceeds (after deducting its portion of Selling Expenses) actually received by such Holder in the sale of
Registrable Securities to which such Registration Statement or Prospectus relates. This indemnity shall be in addition to any liability which such Holder may otherwise have. 

(c) Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification; provided, that any failure or delay to so notify the indemnifying party shall not relieve the indemnifying party of its obligations hereunder, except to the extent that the indemnifying party is actually and
materially prejudiced by reason of such failure or delay. In case a claim or an action that is subject or potentially subject to indemnification hereunder is brought against an indemnified party, the indemnifying party shall be entitled to
participate in and shall have the right, exercisable by giving written notice to the indemnified party as promptly as practicable after receipt of written notice from such indemnified party of such claim or action, to assume, at the indemnifying
party’s expense, the defense of any such claim or action, with counsel reasonably acceptable to the indemnified party; provided, that any indemnified party shall continue to be entitled to participate in the defense of such claim or
action, with counsel of its own choice, but the indemnifying party shall not be obligated to reimburse the indemnified party for any fees, costs and expenses subsequently incurred by the indemnified party in connection with such defense unless
(A) the indemnifying party has agreed in writing to pay such fees, costs and expenses, (B) the indemnifying party has failed to assume the defense of such claim or action within a reasonable time after receipt of notice of such claim or
action, (C) having assumed the defense of such claim or action, the indemnifying party fails to employ counsel reasonably acceptable to the indemnified party, (D) in the reasonable judgment of any such indemnified party, based upon advice
of its counsel, a conflict of interest exists or may potentially exist between such indemnified party and the indemnifying party with respect to such claims or (E) the indemnified party has reasonably concluded that there may be one or more
legal or equitable defenses available to it and/or other any other indemnified party which are different from or additional to those available to the indemnifying party. Subject to the proviso in the foregoing sentence, no indemnifying party shall,
in connection with any one claim or action or separate but substantially similar or related actions arising out of the same general circumstances or allegations, be liable for the fees, costs and expenses of more than one firm of attorneys (in
addition to any local counsel) for all indemnified parties. The indemnifying party shall not have the right to settle a claim or action for which any indemnified party is entitled to indemnification hereunder without the consent of the indemnified
party (not to be unreasonably withheld, conditioned or delayed), and the indemnifying party shall not consent to the entry of any judgment or enter into or agree to any settlement relating to such claim or action unless in either

  
 -21- 

 
case such judgment or settlement does not impose any admission of wrongdoing or injunctive or equitable relief binding on any indemnified party and includes as an unconditional term thereof the
giving by the claimant or plaintiff therein to such indemnified party of a full and final release from all liability in respect of such claim or action. The indemnifying party shall not be liable hereunder for any amount paid or payable or incurred
pursuant to or in connection with any judgment entered or settlement effected with the consent of an indemnified party unless the indemnifying party has also consented to such judgment or settlement (such consent not to be unreasonably withheld,
conditioned or delayed). 
 (d) If the indemnification provided for in this Section 11 is held by a court of competent
jurisdiction to be unavailable to, or unenforceable by, or is for any reason insufficient to hold harmless as contemplated by this Section 11 an indemnified party in respect of any loss, claim, action, damage, liability or expense
referred to herein, then the applicable indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, action, damage, liability
or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, in connection with the statements or omissions which resulted in such loss,
claim, action, damage, liability or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, 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 indemnifying party or by the indemnified party, and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and equitable if contribution pursuant hereto were determined by pro rata
allocation or by any other method or allocation that does not take into account the equitable considerations referred to in this Section 11(d). In no event shall the amount which a Holder of Registrable Securities may be obligated to
contribute pursuant to this Section 11(d) exceed an amount by which the net proceeds (after deducting its portion of Selling Expenses) actually received by such Holder in the sale of Registrable Securities that gives rise to such
obligation to contribute exceeds the amount of any damages which such indemnifying party has otherwise been required to pay by reason of such untrue statement or omission. No indemnified party guilty or liable 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. 

(e) The provisions of this Section 11 shall remain in full force and effect regardless of any investigation made by or on behalf
of any indemnified party or any officer, director or controlling person of such indemnified party and shall survive the Transfer of any Registrable Securities by any Holder. 

  
 -22- 

 Section 12. Rule 144 Compliance . With a view to making available to the Holders of
Registrable Securities the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of Parent to the public without registration, Parent shall: 

(a) make and keep public information available, as those terms are understood and defined in Rule 144; 

(b) use reasonable best efforts to file with the SEC in a timely manner all reports and other documents required of Parent under the
Securities Act and the Exchange Act; 
 (c) furnish to any Holder of Registrable Securities, promptly upon request, a written statement by
Parent as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act; and 
 (d) take such
further action as any Holder of Registrable Securities may reasonably request, to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 or 144A or Regulations S under the Securities Act, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the SEC. 

Section 13. Miscellaneous. 

(a) No Inconsistent Agreements; Additional Rights. Parent represents and warrants that it has not entered into, and agrees that it will
not enter into, any agreement with respect to its securities that violates or subordinates or is otherwise inconsistent with the rights granted to the Holders of Registrable Securities under this Agreement. If Parent enters into any agreement after
the date hereof granting any Person registration rights with respect to any security of Parent which agreement contains any material provisions more favorable to such Person than those set forth in this Agreement, Parent will notify the Holders and
will agree to such amendments to this Agreement as may be necessary to provide these rights to the Holders. 
 (b) Assignment; Third
Party Beneficiaries. The registration rights of the TD Stockholders, the Ricketts Stockholders or the Riney Stockholder under this Agreement with respect to any Registrable Securities of such Holders may be transferred and assigned to any of
their respective Stockholder Transferees (or any trustee or other Person acting on behalf of a Stockholder Transferee) who executes and delivers a counterpart to this Agreement in the form attached hereto as Exhibit A without the prior
written consent of the other parties hereto. Except as provided in the immediately preceding sentence, neither this Agreement nor any of the rights, interests or obligations shall be assigned by any of the parties hereto (other than by operation of
law) without the prior written consent of the other parties. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and assigns. Except (i) as otherwise specifically provided in Section 11, which is intended to benefit each Covered Person, and (ii) for the Stockholder Transferees, this Agreement
(including the documents and instruments referred to herein) is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties
set forth herein. If the TD Stockholders, the Ricketts Stockholders or the Riney Stockholder cease to beneficially own any shares of Common Stock, the Stockholder Transferee of the TD Stockholders, the Ricketts Stockholders or the Riney Stockholder,
as applicable, owning the greatest number of shares of Common Stock among all Stockholder Transferees of the TD Stockholders, the Ricketts Stockholders or the Riney Stockholder, as applicable, shall exercise the rights of the TD Stockholders, the
Ricketts Stockholders or the Riney Stockholder, as applicable, under this Agreement. 

  
 -23- 

 (c) Specific Performance. The parties hereto agree that irreparable damage would occur if
any provision of this Agreement were not performed in accordance with its specific terms or otherwise breached. Accordingly, the parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent
breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby further waives (i) any defense
in any action for specific performance that a remedy at Law would be adequate and (ii) any requirement under Law to post security or a bond as a prerequisite to obtaining equitable relief. 

(d) No Waivers. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. 

(e) Governing Law; Jurisdiction. 

(i) This Agreement shall be governed and construed in accordance with the Laws of the State of Delaware, without regard to any
applicable conflicts of law principles. 
 (ii) Each party agrees that it will bring any action or proceeding in respect of
any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court located in the State of Delaware (the “Chosen Courts”), and, solely in connection with claims
arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding
in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party and (iv) agrees that service of process upon such party in any such action or proceeding will be
effective if notice is given in accordance with Section 13(g). 
 (f) Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND
AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE EXTENT PERMITTED BY LAW AT THE TIME OF
INSTITUTION OF THE APPLICABLE LITIGATION, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH
PARTY CERTIFIES AND ACKNOWLEDGES THAT: (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD 

  
 -24- 

 
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH PARTY MAKES THIS WAIVER
VOLUNTARILY, AND (D) EACH PARTY HAS BEEN INDUCED TO ENTER THIS AGREEMENT BY, AMONG OTHER THINGS, MUTUAL WAIVES AND CERTIFICATIONS IN THIS SECTION 13(F). 

(g) Notices. All notices and other communications hereunder shall be in writing and shall be deemed fully given (i) on the date of
delivery if delivered personally, or if by facsimile, upon confirmation of receipt, or if by e-mail so long as such e-mail states it is a notice delivered pursuant to this Section 13(g) and a duplicate copy of such e-mail is promptly

If to any other Holder, to such address as is designated by such Holder in the counterpart to this Agreement in the form attached hereto as Exhibit A.

 (h) Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. In the event that an
ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of
any provision of this Agreement. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 

(i) Counterparts. This Agreement may be executed in two (2) or more counterparts (including by facsimile or other electronic
means) all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties and delivered to the other party, it being understood that the parties need not sign the same
counterpart. 

  
 -27- 

 (j) Entire Agreement. This Agreement (including the documents and the instruments referred
to herein), together with the Merger Agreement, the Parent Stockholder Agreement (as defined in the Merger Agreement) and the Existing Stockholders Agreement (as defined in the Parent Stockholder Agreement), constitutes the entire agreement among
the parties and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. 

(k) Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such a manner
as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law or rule in any jurisdiction, such
invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or
unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable. 
 (l) Amendments. Subject to
compliance with applicable Law, this Agreement may be amended by the parties hereto, in the case of Parent, by its Board of Directors, and in the case of the Riney Stockholder, by the person or persons then serving as Voting Trustee pursuant to the
terms of the Voting Trust Agreement. This Agreement may not be amended or modified and waivers and consents to departures from the provisions hereof (each, an “Amendment”) may not be given, except by an instrument in writing
specifically designated as an amendment hereto, (A) in the case of a purely administrative amendment, signed on behalf of Parent and the Holder or Holders of Registrable Securities representing at least 67% of the aggregate amount of
Registrable Securities held by the Holders, and (B) in the case of any amendment that is not purely administrative, signed on behalf of Parent and each of TD, TD Lux, the Riney Stockholder and the Ricketts Stockholders. Each Holder of any
Registrable Securities at any time or thereafter outstanding shall be bound by any amendment authorized by this Section 13(l). 

(m) Delivery by Facsimile or Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection
with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e-mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an
original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of a
facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of
a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense. 

  
 -28- 

 (n) Further Assurances. Each party to this Agreement shall cooperate and take such action
as may be reasonably requested by another party to this Agreement in order to carry out the provisions and purposes of this Agreement and the transactions contemplated hereby. 

(o) Termination. This Agreement shall terminate (i) with respect to the Riney Parties, upon such time as the Riney Parties
collectively hold or beneficially own, in the aggregate, an equity interest in Parent of less than 1% of the outstanding shares of Common Stock, and (ii) with respect to any Holder that is not a Riney Party, upon such time as such Holder holds
or beneficially owns, in the aggregate, an equity interest in Parent of less than 1% of the outstanding shares of Common Stock, provided that, in each case, the provisions of Sections 10, 11 and this Section 13
shall survive such termination. 
 (p) Withdrawal. At any time, any Holder may elect to withdraw from this Agreement and no longer be
subject to the obligations of this Agreement or have rights under this Agreement from that date forward; provided, that a Holder withdrawing from this Agreement shall nonetheless be obligated under Section 6(a) with respect to any
underwritten offering then pending to the same extent that such Holder would have been obligated if the Holder had not withdrawn and be entitled to participate under Section 2, Section 3, and Section 5 in any
underwritten offering then pending to the same extent that such Holder would have been entitled to if the Holder had not withdrawn; and provided, further, that no withdrawal from this Agreement shall terminate a Holder’s rights or
obligations under Section 11 above with respect to any prior registration or underwritten offering then pending. 
 (q)
Existing Registration Rights Agreement. This Agreement shall amend and restate the Existing Registration Rights Agreement and, as of the date hereof, the Existing Registration Rights Agreement shall terminate and be of no further force and
effect, in each case with respect to TD and the Ricketts Stockholders (as defined in the Existing Registration Rights Agreement).

 (g) Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. In the event that an
ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of
any provision of this Agreement. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. This Agreement shall not be interpreted
or construed to require any person to take any action, or fail to take any action, if to do so would violate any applicable Law. 
 (h)
Counterparts. This Agreement may be executed in two (2) or more counterparts (including by facsimile or other electronic means), all of which shall be considered one and the same agreement and shall become effective when counterparts
have been signed by each of the parties and delivered to the other parties, it being understood that the parties need not sign the same counterpart. 

(i) Entire Agreement. This Agreement (including the documents and the instruments referred to herein), together with the Merger
Agreement, the Confidentiality Agreement (as such term is defined in the Merger Agreement), the Escrow Agreement, the Registration Rights Agreement and the Support Agreements (as such term is defined in the Merger Agreement), constitutes the entire
agreement among the parties and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. 

(j) Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such a manner
as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law or rule in any jurisdiction, such
invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or
unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable. 

  
 -14- 

 (k) Amendments and Waivers. Subject to compliance with applicable Law, this Agreement may
be amended by the parties hereto, in the case of the Company, by action taken or authorized by the Board or any designated committee thereof, and in the case of the Voting Trustee, by the Representative. This Agreement may not be amended, modified,
waived or supplemented in any manner, whether by course of conduct or otherwise, except (i) in the case of an amendment or modification, such amendment or modification is in writing, is specifically identified as amendment hereto and is signed
by the Company and the Representative or (ii) in the case of a waiver, such waiver is in writing and signed by the Company, if the waiver is to be effective against the Company, or the Representative, if the waiver is to be effective against
any Riney Party; provided that, without the prior written consent of TD, no provision of this Agreement may be amended, modified or waived in any way that would reasonably be expected to adversely affect TD’s rights hereunder or its
rights, benefits or obligations under the Existing Stockholders Agreement. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable Law. 

(l) Delivery by Facsimile or Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection
with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e-mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an
original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of a
facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of
a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense. 

(m) Further Assurances. Each party to this Agreement shall cooperate and take such action as may be reasonably requested by another
party to this Agreement in order to carry out the provisions and purposes of this Agreement and the transactions contemplated hereby. 
 (n)
Representative. As long as the Voting Trustee owns any shares of Common Stock, the Voting Trustee shall act as the representative (the “Representative”) for all Riney Parties hereunder, and each Riney Party acknowledges and
agrees that the Representative shall have full power, authority and discretion to take (or refrain from taking) any and all actions and execute and deliver any and all documents, including any amendments or supplements to this Agreement, as it deems
necessary or desirable, in its sole discretion, on their behalf, and each Riney Party shall be bound by any such action taken, documented executed or other determination by the Representative. If the Voting Trustee ceases to Beneficially Own any
shares of Common Stock, the Riney Parties shall cooperate in good faith to appoint a replacement Representative to act for all Riney Parties in accordance with the preceding sentence, and if no agreement can be reached, the Riney Party owning the
greatest number of shares of Common Stock among all Riney Parties shall act as the Representative for all Riney Parties in accordance with the preceding sentence. Any such Person shall thereafter be deemed the Representative for purposes of this
Agreement. 

  
 -15- 

 (o) Notwithstanding anything in this Agreement to the contrary, this Agreement shall not
(i) require or obligate any Riney Family Member to take any action that would require the filing of a Schedule 13G or a Schedule 13D with the SEC or (ii) prohibit, restrict or limit in any way the Transfer of Beneficial Ownership of Voting
Securities by any Riney Family Member to any other Riney Family Member through the Trust through the issuance, exchange or cancellation of any certificates granting the holder thereof the rights set forth in the Voting Trust Agreement (each, a
“Voting Trust Certificate”); provided, that the Voting Securities represented thereby remain Beneficially Owned and held of record by the Trust. 

(p) Term and Termination. 

(i) This Agreement will be effective as of the date hereof and shall terminate on the earliest of (x) the first day on or
prior to the third anniversary of this Agreement that the Riney Parties, in the aggregate, cease to Beneficially Own at least a number of shares of Common Stock equal to 66 2/3% of the number of shares of Common Stock included in the Stock
Consideration (as such term is defined in the Merger Agreement), (y) the first day after the third anniversary of this Agreement that the Riney Parties, in the aggregate, cease to Beneficially Own at least a number of shares of Common Stock
equal to 85% of the number of shares of Common Stock included in the Stock Consideration and (z) at the election of the Representative upon not less than six (6) months’ prior written notice to the Company, which notice shall be
irrevocable, a date that is at least four (4) years from the date hereof (such date of termination, the “Termination Date”); provided that (A) the provisions of this Section 6 shall survive such
termination and (B) in the event of a termination of this Agreement pursuant to Section 6(p)(i)(z), the provisions of Section 4(a) of this Agreement shall survive such termination for a period of six (6) months
after the Termination Date. 
 (ii) Within three (3) business days after the occurrence of an event that would result
in the termination of this Agreement pursuant to Section 6(p)(i)(x) or Section 6(p)(i)(y), the Riney Parties shall provide written notice of such occurrence to the Company.
