 4. Demand Registration Rights. 
 (a) At any time during the Demand Period, upon the written request of either of the Fidelity Stockholder or the Wayzata Stockholder (each of the Fidelity Stockholder and the Wayzata Stockholder, the “Initiating Demand
Stockholder”) that the Company effect the registration under the Securities Act of all or part of such Initiating Demand Stockholder’s Registrable Common Shares (which written request shall specify the aggregate number of Registrable
Common Shares requested to be registered) (a “Demand Request”), the Company shall as soon as reasonably practicable, but no later than 45 Business Days after its receipt of such request, file with the SEC a Registration Statement
with respect to such requested registration (or, if the Company shall be legally prohibited from making such a filing or if financial statements required to be included in such a filing are not reasonably available, in each case, within 45 Business
Days after its receipt of such request, as soon thereafter as is legally permissible or as such financial statements are reasonably available). Subject to reduction pursuant to Section 6(a), such Registration Statement shall cover the
Registrable Common Shares requested by the Initiating Demand Stockholder to be registered and such other Registrable Common Shares as are requested to be registered by any other Stockholder pursuant to Section 5. 
 (b) Notwithstanding the provisions of Section 4(a), the Company shall not be required to take any action pursuant to this Section 4:

 (i) if, prior to the date of a request by the Fidelity Stockholder pursuant to Section 4(a), the Company shall
have effected one registration pursuant to Section 4(a) at the request of the Fidelity Stockholder; 
 (ii) if,
prior to the date of a request by the Wayzata Stockholder pursuant to Section 4(a), the Company shall have effected one registration pursuant to Section 4(a) at the request of the Wayzata Stockholder; 
 (iii) if the Company shall have effected a registration pursuant to Section 4(a) within the 180-day period immediately preceding the
date of such request; 
 (iv) if the Registrable Common Shares of the Initiating Demand Stockholder which the Company
shall have been requested to register shall have an anticipated aggregate offering price of less than $35,000,000, as determined in good faith by the Company at the time of its receipt of a request for registration pursuant to Section 4(a); or

  

 -7- 

 (v) during the pendency of any Blackout Period; 
 provided, however, that the Company shall be permitted to satisfy its obligations under Section 4(a) by amending (to the extent permitted by applicable law) within
45 days after a written request for registration, any Registration Statement previously filed by the Company under the Securities Act so that such Registration Statement (as amended) shall permit the disposition pursuant to an Underwritten Offering
of all of the Registrable Common Shares for which a demand for registration has been made under Section 4(a). If the Company shall so amend a previously filed Registration Statement, it shall be deemed to have effected a registration for
purposes of this Section 4. 
 (c) The Initiating Demand Stockholder delivering a request pursuant to Section 4(a) may
distribute the Registrable Common Shares covered by such demand only by means of an Underwritten Offering. 
 (d) Subject to
Section 4(e), and notwithstanding the last sentence of Section 4(b), a registration requested pursuant to this Section 4 shall not be deemed to be effected for purposes of this Section 4 if (i) the Registration Statement for
such registration has not been declared effective by the SEC or has not become effective in accordance with the Securities Act and the rules and regulations thereunder, or (ii) the Initiating Demand Stockholder shall not be entitled to include
in such registration at least 75% of the Registrable Common Shares that the Initiating Demand Stockholder requested pursuant to Section 4(a) to be so included in such registration. 
 (e) The Initiating Demand Stockholder may, at any time prior to the effective date of the Registration Statement relating to such registration,
revoke such request by providing a written notice to the Company revoking such request. The Company shall be deemed to have effected a registration pursuant to Section 4(a) in the case of any such revocation unless the Initiating Demand
Stockholder reimburses the Company for all Registration Expenses incurred by the Company with respect to such revoked request. Except as otherwise contemplated by the immediately preceding sentence, no revocation pursuant to this Section 4(e)
shall relieve the Company of its obligation hereunder to pay the Registration Expenses in connection with any such request. 
 (f) Any
request or notice furnished by an Initiating Demand Stockholder pursuant to this Section 4 shall (i) specify the Stockholders constituting the Initiating Demand Stockholder that have joined in such request or notice and (ii) be
binding upon each Stockholder holding Registrable Common Shares that constitutes a part of such Initiating Demand Stockholder, whether or not joining in such request or notice. 
 5. Piggy-Back Registration Rights. 
 (a) Within seven Business Days after receipt by the Company of a Demand Request pursuant to Section 4(a), the Company shall (i) give written notice of its receipt of such Demand Request to each other Stockholder holding
Registrable Common Shares that has not joined in such Demand Request, specifying the approximate date on 

  

 -8- 

 
which the Company proposes to file a Registration Statement pursuant to Section 4(a) and advising such Stockholder of its right to have any or all of
the Registrable Common Shares of such Stockholder included among the securities to be covered thereby, and (ii) at the written request of any such Stockholder given to the Company within ten Business Days after written notice from the Company
has been given to such Stockholder, include among the securities covered by such Registration Statement the number of Registrable Common Shares which such Stockholder shall have requested be so included (subject, however, to reduction, in accordance
with the applicable provisions of Section 6). 
 (b) Nothing in this Section 5 shall create any liability on the part of the
Company to any Stockholder holding Registrable Common Shares if for any reason the Company shall decide not to file, or to delay the filing of, a Registration Statement proposed to be filed pursuant to Section 4(a) or to withdraw such
Registration Statement subsequent to its filing, regardless of any action whatsoever that a Stockholder may have taken, whether as a result of the issuance by the Company of any notice hereunder or otherwise; provided, however, that the Company
shall not be relieved of its obligation hereunder to pay the Registration Expenses in connection with any such filing or proposed filing. 
 6. Cutbacks. In connection with any offering covered by a Registration Statement filed pursuant to Section 4(a), if the lead managing underwriters shall give written notice (a “Cutback Notice”) to the Company
(it being understood that the Company shall as soon as reasonably practicable deliver copies of any such notice to all Stockholders who have requested the Company to include Registrable Common Shares in such offering) that, in their reasonable and
good faith opinion, the Registrable Common Shares requested to be included in such offering and any other securities which the Company proposes to sell for its own account in such offering exceed the number which can be sold in such offering without
being likely to have a significant adverse effect on the offering price, timing or distribution of the securities offered or the market for the securities offered (an “Adverse Offering Effect”), then the Company shall include in
such offering only the number of Registrable Common Shares and other securities that, in the good faith opinion of such underwriters, can be included without having an Adverse Offering Effect. Such aggregate number of Registrable Common Shares to be
included in such offering shall be allocated pro-rata among the Stockholders who have requested Registrable Common Shares be so included based on the number, as of the date of delivery of the first Cutback Notice delivered to the Stockholders in
connection with such offering, of Registrable Common Shares requested by the Stockholders to be included in such offering. No other securities shall be included in such offering except to the extent that, in the reasonable and good faith opinion of
such lead managing underwriter or underwriters, such securities can be included without having an Adverse Offering Effect.

 8. Blackout Periods; Holdback. 
 (a) If the Company determines that the registration and distribution of Registrable Common Shares (i) would materially impede, delay, interfere
with or otherwise adversely affect any pending financing, registration of securities by the Company in a primary offering for its own account, acquisition, corporate reorganization, debt restructuring or other significant transaction involving the
Company or (ii) would require disclosure of non-public material information that the Company has a bona fide business purpose for preserving as confidential, as determined by the Company’s Board of Directors in good faith, the
Company shall be entitled to defer the filing or effectiveness of a Registration Statement, or to suspend the use of an effective Registration Statement, for the shortest period of time reasonably required (each such period, a “Blackout
Period”); provided that the Company shall not be entitled to obtain deferrals or suspensions under (x) clause (i) of this Section 8(a), for more than an aggregate of 120 days in any 12-month period or (y) clause
(ii) of this Section 8(a), for more than 30 days on any one occasion, on more than two occasions in any 12-month period or for more than an aggregate of 60 days in any 12-month period. The Company shall notify each Stockholder of the
initiation and expiration or earlier termination of a Blackout Period and, as soon as reasonably practicable after such expiration or termination, shall amend or supplement any effective Registration Statement to the extent necessary to permit the
Stockholders to resume use thereof in connection with the offer and sale of their Registrable Common Shares in accordance with applicable law. Each Stockholder agrees to treat as confidential the delivery of any notice by the Company to such
Stockholder pursuant to this Section 8(a) and the information set forth in any such notice. 
 (b) In the case of an Underwritten
Offering of securities of the Company, each Stockholder agrees, if requested in writing by the lead managing underwriter of such Underwritten Offering, that it shall not effect any public sale or public distribution of any Registrable Common Shares
held by such Stockholder during the period beginning seven days before, and ending 90 days (or such shorter period as may be permitted by such lead managing underwriter) after, the effective date of the Registration Statement filed in
connection with such registration, except for Registrable Common Shares included in such registration; provided, that all directors and executive officers of the Company who hold Common Stock enter into lock-up agreements with respect to their
Common Stock not included in such registration with the applicable underwriters on terms no less restrictive than the terms of this Section 8(b) applicable to such Stockholder. If requested by such managing underwriter, each Stockholder shall
(i) enter into a lock-up agreement with the applicable underwriters that is consistent with the agreement in the preceding sentence and (ii) cause each of its Affiliates holding Designated Shares to enter into such a lock-up agreement with
respect to such Designated Shares. 
 (c) Notwithstanding any provision of Section 8(a) or 8(b) to the contrary, the cumulative
period of any Blackout Periods pursuant to Section 8(a) and of any holdbacks pursuant to Section 8(b) shall not exceed, in the aggregate, 120 days in any 12-month period. 
 (d) In the case of any Underwritten Offering of Registrable Common Shares initiated by a Stockholder pursuant to Section 4(a), the Company
agrees, if requested in writing by the lead managing underwriters of such Underwritten Offering, not to effect (or register for sale) any public sale or distribution of any securities that are Similar Securities for the Company’s own account
during the period beginning seven days before, and ending 

  

 -10- 

 
90 days (or such lesser period as may be permitted by such lead managing underwriter) after, the effective date of the Registration Statement filed in
connection with such registration, except for securities of the Company to be offered for the Company’s account in such Underwritten Offering. Notwithstanding the foregoing, the Company may effect a public sale or distribution of Common Stock
and other securities that are Similar Securities for the Company’s own account during the period described above (i) pursuant to registrations on Forms S-4 or S-8 or any successor registration forms, (ii) as part of any registration
of securities for offering and sale to employees, directors or consultants of the Company pursuant to any stock plan or other benefit plan arrangement, (iii) pursuant to any Warrant Shelf Registration or (iv) in an amount that shall not
exceed the volume limitations set forth in Rule 144(e)(1). The Company agrees to use commercially reasonable efforts to obtain from directors or executive officers of the Company who hold Common Stock or other securities that are Similar Securities
an agreement not to effect any public sale or distribution of such Similar Securities (other than any sale under Rule 144) for the account of such director or executive officer during any period referred to in this Section 8(d), except as part
of any Underwritten Offering contemplated in this Section 8(d). 
 9. Registration Procedures. In connection with the
registration obligations of the Company under Sections 3, 4 and 5, the Company shall: 
 (a) prepare and file with the SEC a Registration
Statement with respect to such Registrable Common Shares on any registration form adopted by the SEC for which the Company then qualifies or which counsel for the Company shall deem appropriate (subject, in the case of a Shelf Registration

such Registration Statement to become and, subject to Section 3(b), remain effective; provided that, at least five Business Days prior to filing a Registration Statement or Prospectus or any amendment or supplement thereto, the Company shall

proposed to be filed (including, upon the request of such counsel, documents to be incorporated by reference therein), which documents shall be subject to the reasonable review and comments of such counsel and the Stockholders holding the
Registrable Common Shares included or to be included in such Registration Statement during such five-Business-Day period; 
 (b) prepare and file with the SEC amendments and post-effective amendments to such
Registration Statement and such amendments and supplements to the Prospectus used in connection therewith as may be necessary to maintain the effectiveness of such registration or as may be required by the rules, regulations or instructions

Shares covered by such Registration Statement cease to be Registrable Common Shares or have been sold or withdrawn and (ii) subject to Sections 9(e) and 9(k), (x) in the case of the Shelf Registration, until the date that is 10 days
following the Shelf Termination Date, or (y) in the case of a Registration Statement filed pursuant to Section 4(a), for at least 120 days plus such longer period (not to exceed 90 days after the 120th day) as, in the

 (d) use commercially reasonable efforts to register or qualify such Registrable Common Shares covered by such Registration Statement under such
other securities or blue sky laws of such jurisdictions as each Stockholder shall reasonably request, and to do any and all other acts and things which may be reasonably necessary to enable such Stockholder to consummate the disposition in such
jurisdictions of the Registrable Common Shares held by such Stockholder, except that the Company shall not be required for any such purpose to qualify generally to do business as a foreign corporation in any jurisdiction where, but for the
requirements of this Section 9(d), it would not be obligated to be so qualified, to subject itself to taxation in any such jurisdiction, or to consent to general service of process in any such jurisdiction;

effect, includes an untrue statement of material fact or omits 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 (the period during which
the Stockholders are required in such case pursuant to Section 10(b) to refrain from effecting public sales or distributions of Registrable Common Shares referred to herein as a “Section 9(e) Period”), and prepare and furnish
to such Stockholder, as soon as reasonably practicable, without charge to such Stockholder, a reasonable number of copies of an amendment to such Registration Statement or supplement to such related Prospectus as may be necessary so that, as
thereafter delivered to the purchasers of such Registrable Common Shares, 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

 -13- 

 (j) if reasonably requested by the managing underwriter or underwriters or a Stockholder holding
Registrable Common Shares being sold in connection with an Underwritten Offering, incorporate in a Prospectus supplement or post-effective amendment to the Registration Statement such information as the managing underwriters and the Stockholders
holding a Majority of the Registrable Common Shares being sold by all Stockholders agree should be included therein relating to the plan of distribution with respect to such Registrable Common Shares, including information with respect to the amount
of Registrable Common Shares being sold to such underwriters, the purchase price being paid therefor by such underwriters and any other terms of the Underwritten Offering of the Registrable Common Shares to be sold in such offering and make all
required filings of such Prospectus supplement or post-effective amendment upon being notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 
 (k) in the event of the issuance of any stop order of which the Company is aware suspending the effectiveness of the Registration Statement, or of
any order suspending or preventing the use of any related Prospectus or suspending the qualification of any Registrable Common Shares included in the Registration Statement for sale in any jurisdiction, use commercially reasonable efforts to obtain
at the earliest practicable time the withdrawal of such stop order or other order (the period between the issuance and withdrawal of any stop order or other order referred to herein as a “Section 9(k) Period”); provided that the
Company shall extend the period during which such Registration Statement will be maintained effective as provided in Section 9(b) by the number of days in the Section 9(k) Period; 
 (l) use reasonable best efforts to cause all Common Stock covered by such Registration Statement to be listed on any securities exchange on which
the Common Stock is then listed, if the Common Stock covered by such Registration Statement is not already so listed and if such listing is then permitted under the rules of such securities exchange;

Registrable Common Shares shall be registered in book-entry form, provide the applicable transfer agent and registrar for such Registrable Common Shares with printed certificates for the Registrable Common Shares, which certificates shall be in a
form eligible for deposit with The Depository Trust Company;

accounting firm that has certified the Company’s financial statements to make themselves available during normal business hours to discuss the business of the Company and to supply all information reasonably requested by any such Stockholders
or managing underwriter or agent thereof in connection with such Registration Statement as shall be necessary to enable such Persons to exercise their due diligence responsibility (subject to the entry by each Person referred to in this
Section 9(q) into customary confidentiality agreements in a form reasonably acceptable to the Company). 
 10. Agreements of
Stockholders. 
 (a) As a condition to the Company’s obligation under this Agreement to cause Registrable Common Shares of any
Stockholder to be included in a Registration Statement, such Stockholder shall timely provide the Company with all of the information required to be provided in the Registration Statement with respect to such Stockholder pursuant to Items 507 and
508 (or any successor Items) of Regulation S-K under the Securities Act and such other information as otherwise may reasonably be requested by the Company in connection with the Registration Statement. 
 (b) Each Stockholder shall comply with the prospectus delivery requirements of the Securities Act in connection with the offer and sale of
Registrable Common Shares made by such Stockholder pursuant to any Registration Statement. Upon receipt of any notice from the Company of the occurrence of any event of the kind described in Section 9(e) or Section 9(k), each Stockholder
holding Registrable Common Shares shall forthwith discontinue the disposition of Registrable Common Shares pursuant to the Prospectus or Registration Statement covering such Registrable Common Shares until such Stockholder’s receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 9(e) or the withdrawal of any stop order or other order referred to in Section 9(k), and, if so directed by the Company, shall deliver to the Company all copies,
other than permanent file copies then in such Stockholder’s possession, of the Prospectus covering such Registrable Common Shares at the time of receipt of such notice. 
 (c) Each Stockholder shall effect all sales and distributions of such Stockholder’s Registrable Common Shares made pursuant to the Shelf
Registration Statement in a manner consistent with the terms of the Plan of Distribution, subject to Section 3(c).

determined by the Company, a Stockholder shall consent to disclosure in any Registration Statement to the effect that such Stockholder is or may be deemed to be an underwriter for purposes of the Securities Act in connection with the offering of
Registrable Common Shares of such Stockholder included in such Registration Statement. 
 (e) Each Stockholder shall comply with
Regulation M under the Exchange Act in connection with the offer and sale of Registrable Common Shares made by such Stockholder pursuant to any Registration Statement. Each Stockholder shall provide the Company with such information about such
Stockholder’s offer and sale of Registrable Common Shares pursuant to any Registration Statement as the Company shall reasonably request to enable the Company and its Affiliates to comply with Regulation M under the Exchange Act in connection
with any such offer and sale. 
 11. Registration Expenses. The Company shall pay all Registration Expenses in connection with all
registrations pursuant to this Agreement to the extent provided herein. In connection with all such registrations, each Stockholder shall pay all underwriting discounts and fees, brokerage and sales commissions, and transfer and documentary stamp
taxes, if any, relating to the sale or disposition of such Stockholder’s Registrable Common Shares pursuant to the Registration Statement, and, except as provided in clause (g) of the definition of Registration Expenses, all fees and
expenses of counsel to such Stockholder. 
 12. Indemnification; Contribution. 
 (a) The Company shall indemnify and hold harmless, to the fullest extent permitted by law, each Stockholder in any offering or sale of Registrable
Common Shares pursuant to this Agreement, each Person, if any, who participates as an underwriter in any such offering and sale of Registrable Common Shares, and each Person, if any, who controls such Stockholder or such underwriter within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and their respective directors, trustees, officers, partners, agents, employees and affiliates against all losses, claims, damages, liabilities and expenses
(including reasonable attorneys’ fees, disbursements and expenses, as incurred, and any amounts paid in any settlement effected with the Company’s consent, which consent shall not be unreasonably withheld or delayed) (collectively,
“Losses”) incurred by such party pursuant to any actual or threatened action, suit, proceeding or investigation arising out of or based upon: (i) any untrue or alleged untrue statement of a material fact contained in, or any
omission or alleged omission of a material fact required to be stated in, the Registration Statement, Prospectus or preliminary Prospectus or any amendment or supplement to any of the foregoing, any Issuer Free Writing Prospectus or any “issuer
information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or necessary to make the statements therein (in the case of a Prospectus, a preliminary Prospectus, an Issuer Free Writing Prospectus or “issuer
information,” in the light of the circumstances then existing) not misleading, except in each case insofar as such statements or omissions arise out of or are based upon (A) any such untrue statement or alleged untrue statement or omission
or alleged omission made in reliance on and in conformity with information with respect to such Stockholder furnished in writing to the Company by such Stockholder or its counsel expressly for use therein, (B) the use of any Prospectus, Issuer
Free Writing Prospectus or “issuer information” after such time as the obligation of the Company to keep effective the 

  

 -16- 

 
Registration Statement of which such Prospectus forms a part has expired or (C) the use of any Prospectus, Issuer Free Writing Prospectus or
“issuer information” after such time as the Company has advised the Stockholders that the filing of an amendment or supplement thereto is required, except such Prospectus, Issuer Free Writing Prospectus or “issuer information” as
so amended or supplemented; or (ii) any violation by the Company of any other federal or state securities laws or regulations applicable to the Company and relating to action required of or inaction by the Company in connection with any such
registration. Notwithstanding the foregoing provisions of this Section 12(a), the Company shall not be liable to any such Stockholder or underwriter or to any other indemnified party under the indemnity agreement in this Section 12(a) for
any Losses that arise out of or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Prospectus if either: (i) (A) such Stockholder or underwriter failed to send or deliver a copy of the
Prospectus with or prior to the delivery of written confirmation of the sale of Registrable Common Shares by such Stockholder or underwriter to the Person asserting the claim from which such Losses arise and (B) the Prospectus would have
corrected such untrue statement or alleged untrue statement or such omission or alleged omission; or (ii) (A) such untrue statement or alleged untrue statement or omission or alleged omission is corrected in an amendment or supplement to
the Prospectus and (B) having previously been furnished by or on behalf of the Company with copies of the Prospectus as so amended or supplemented as required hereunder, such Stockholder or underwriter thereafter fails to deliver such
Prospectus, as so amended or supplemented, with or prior to the delivery of written confirmation of the sale of Registrable Common Shares by such Stockholder or underwriter to the Person asserting the claim from which such Losses arise. Such rights
to indemnity and reimbursement of expenses shall survive the transfer of the Registrable Common Shares by such indemnified party. 
 (b) In connection with any Registration Statement filed pursuant to this Agreement, each Stockholder holding Registrable Common Shares to be covered thereby shall, severally and not jointly with any other Stockholders, indemnify and
hold harmless, to the fullest extent permitted by law, the Company, each Person, if any, who participates as an underwriter in any such offering and sale of Registrable Common Shares and each Person, if any, who controls the Company or such
underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and their respective directors, trustees, officers, partners, agents, employees and affiliates, against all Losses incurred by such party
pursuant to any actual action, suit, proceeding or investigation arising out of or based upon any untrue or alleged untrue statement of a material fact contained in, or any omission or alleged omission of a material fact required to be stated in,
the Registration Statement, Prospectus or preliminary Prospectus or any amendment or supplement to any of the foregoing, any Issuer Free Writing Prospectus or “issuer information” filed or required to be filed pursuant to Rule 433(d) under
the Securities Act, or necessary to make the statements therein (in case of a Prospectus, preliminary Prospectus or Issuer Free Writing Prospectus, in the light of the circumstances then existing) not misleading, but only to the extent that any such
untrue statement or omission is made in reliance on and in conformity with information with respect to such Stockholder furnished in writing to the Company by such Stockholder or its counsel specifically for use therein; provided, however, that no
Stockholder shall be required to indemnify the Company or any other indemnified party under this Section 12(b) with respect to any amount in excess of the amount of the total net proceeds received by such Stockholder from sales of the
Registrable Common Shares of such Stockholder under such Registration Statement. 
  

 -17- 

 (c) Any Person entitled to indemnification hereunder agrees to give prompt written notice to the
indemnifying party after the receipt by such indemnified party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which such indemnified party may claim indemnification or
contribution pursuant to this Agreement, provided that failure to give such notification shall not affect the obligations of the indemnifying party pursuant to this Section 12 except to the extent the indemnifying party shall have been actually
and materially prejudiced as a result of such failure. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, 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 shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case
subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation, unless in the reasonable judgment of any indemnified party, based on the opinion of counsel, a conflict of interest
is likely to exist between the indemnifying party and such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall not be liable for the fees and expenses of (i) more
than one counsel for all Stockholders holding Registrable Common Shares who are indemnified parties, selected by the Stockholders holding a Majority of the Registrable Common Shares held by all Stockholders who are indemnified parties (which
selection shall be reasonably satisfactory to the Company), (ii) more than one counsel for the underwriters in an Underwritten Offering or (iii) more than one counsel for the Company, in each case in connection with any one action or
separate but similar or related actions. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party, based on the opinion of counsel, a conflict of interest is likely to exist between an indemnified party and any other of such indemnified
parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel, provided that the indemnifying party shall not be liable for the fees and expenses of (i) more
than one counsel for all Stockholders holding Registrable Common Shares who are indemnified parties, selected by the Stockholders holding a Majority of the Registrable Common Shares who are indemnified parties (which selection shall be reasonably
satisfactory to the Company), (ii) more than one counsel for the underwriters in an Underwritten Offering or (iii) more than one counsel for the Company, in each case in connection with any one action or separate but similar or related
actions. No indemnifying party, in defense of any such action, suit, proceeding or investigation, shall, except with the consent of each indemnified party, consent to the entry of any judgment or entry into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such action, suit, proceeding or investigation to the extent such liability is covered by the indemnity
obligations set forth in this Section 12. No indemnified party shall consent to entry of any judgment or entry into any settlement without the consent of each indemnifying party. 
 (d) If the indemnification from the indemnifying party provided for in this Section 12 is unavailable to an indemnified party hereunder in
respect of any Losses, 

  

 -18- 

 
then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a
result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions which resulted in such Losses, as well as any other relevant equitable
considerations; provided, however, that no Stockholder shall be required to contribute any amount in excess of the amount of the total net proceeds received by such Stockholder from sales of the Registrable Common Shares of the Stockholder under the
applicable Registration Statement. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue statement or alleged untrue
statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses referred to above shall be deemed to include, subject to the limitations set forth in Section 12(c), any legal
or other fees and expenses reasonably incurred by such indemnified party in connection with any investigation or proceeding. 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 parties agree that it would not be just and equitable if contribution pursuant to this Section 12(d) were determined by pro rata allocation or
by any other method of allocation that does not take into account the consideration referred to in this Section 12(d). If indemnification is available under this Section 12, the indemnifying parties shall indemnify each indemnified party
to the full extent provided in Section 12(a) or 12(b), as the case may be, without regard to the relative fault of such indemnifying parties or indemnified party or any other equitable consideration provided for in this Section 12(d).

 (e) The provisions of this Section 12 shall be in addition to any liability which any indemnifying party may have to any
indemnified party and shall survive the termination of this Agreement. 
 (f) The indemnification and contribution required by this
Section 12 shall be made by periodic payments of the amount thereof during the course of any action, suit, proceeding or investigation, as and when invoices are received or Losses are incurred. 
 13. Participation in Underwritten Offerings. No Stockholder holding Registrable Common Shares may participate in any Underwritten Offering
pursuant to this Agreement unless such Stockholder (a) agrees to sell such Stockholder’s Registrable Common Shares on the basis provided in any underwriting arrangements approved by the Company, which approval shall not be unreasonably
withheld, conditioned or delayed, and (b) completes and executes all questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting
arrangements. 
 14. Reports Under the Exchange Act. For so long as any Registrable Common Shares remain outstanding and the Company
is required under the Exchange Act and rules and regulations thereunder to file with the SEC reports pursuant to Section 13 or 15(a) of the Exchange Act, the Company shall use reasonable best efforts to file such reports with the SEC in a
timely manner. 
  

 -19- 

 15. No Inconsistent Agreements. The Company shall not after the date of this Agreement enter into
any agreement which is inconsistent with the rights granted pursuant to this Agreement to the Stockholders holding Registrable Common Shares. The Stockholders agree for purposes of this Section 15 that a registration rights agreement in
customary form relating to a Rule 144A Resale Shelf Registration shall not be deemed inconsistent with the rights of the Stockholders hereunder. 
 16. Assignment of Registration Rights. 
 (a) The right to cause the Company to register Registrable Common Shares pursuant to
this Agreement may be assigned (but only with all related obligations hereunder) by any Stockholder holding Registrable Common Shares as of the date of this Agreement only in connection with a transfer of such Registrable Common Shares to a Person
that is an Affiliate of such Stockholder and that is not a natural Person; provided, that, in each case, as a condition to the effectiveness of any such assignment, such Person shall be required to execute a counterpart of this Agreement. Upon such
Person’s execution of such counterpart, such Person shall be a Stockholder under this Agreement and shall be entitled to the benefits of, and shall be subject to the restrictions contained in, this Agreement, as amended from time to time, that
are applicable hereunder to the Stockholder from whom such rights hereunder were assigned. From and after the date of any such effective assignment, the term “Stockholders” as used herein shall also refer to such Person. 
 (b) In connection with any merger, consolidation, reorganization or similar transaction involving the Company (i) in which the Company is not the
surviving corporation or entity or (ii) which results in the Company becoming the wholly-owned subsidiary of another corporation or other entity, effective provisions shall be made in the instruments pursuant to which such transaction shall be
consummated so that the surviving corporation (in the case of a transaction of the type specified in clause (i)) or the entity which becomes the wholly-owned parent of the Company (in the case of a transaction of the type specified in clause (ii))
shall expressly assume the obligations of the Company hereunder effective upon the consummation of such transaction. In such event, all references herein to the Company shall thereafter be references to the assuming entity and all references to the
Common Stock shall thereafter be references to the class of equity securities (if any) of the assuming entity issued to all holders of the Common Stock as consideration pursuant to such transaction. 
 17. Binding Effect; Benefit. This Agreement shall inure to the benefit of and be binding upon the parties hereto, any Stockholder and any
successor and permitted assign thereof; provided, however, that, except as provided in Section 16, this Agreement and the provisions of this Agreement that are for the benefit of the Stockholders shall not be assignable by any Stockholder, and
any such purported assignment shall be null and void. Except to the extent provided in Section 12, nothing in this Agreement, expressed or implied, is intended to confer upon any Person other than the Company, the Stockholders and their
respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement. No purchaser of Registrable Common Shares from a Stockholder shall be deemed to be a successor or assignee of such
Stockholder merely by reason of such purchase.

departures from the provisions hereof (each such amendment, modification, supplement, waiver or consent, an “Amendment”) may not be given, unless the Company consents thereto and has obtained the written consent thereto of
Stockholders holding a Majority of the Registrable Common Shares; provided that, if any Amendment would adversely affect either the Fidelity Stockholder or the Wayzata Stockholder, then such Amendment shall also require the written consent of the
Fidelity Stockholder or the Wayzata Stockholder, as applicable.

Wayzata Stockholder pursuant to Section 18(a) shall only be effective if signed by the Stockholders holding a Majority of the Registrable Common Shares held by all of the Stockholders that collectively constitute the Fidelity Stockholder or the
Wayzata Stockholder, as applicable, and any such properly given written consent shall be binding upon each Stockholder holding Registrable Common Shares that constitutes a part of the Fidelity Stockholder or the Wayzata Stockholder, as the case may
be. Each Stockholder from time to time shall be bound by any Amendment effected pursuant to this Section 18, whether or not any notice, writing or marking indicating such Amendment appears on the Registrable Common Shares or is delivered to
such Stockholder.

to any particular provision of this Agreement. 
  

 -21-

shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument. Subject to Section 24, this Agreement shall become effective as between the Company and any Stockholder when the Company and such
Stockholder shall have received a copy of counterparts hereof signed by the other. 
 22. Governing Law. THIS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ITS PRINCIPLES OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS

Effectiveness; Termination.

 -22- 

 
this Agreement. Notwithstanding any such termination of this Agreement by any Stockholder, all rights, liabilities and obligations of such Stockholder under
Sections 11 and 12 shall remain in effect in accordance with their terms. No termination of any provision of this Agreement shall relieve any party of any liability for any breach of such provision occurring prior to such termination.

 25. Entire Agreement. This Agreement is intended by the parties to be a complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted by the Company with respect to the Registrable Common Shares. There are no restrictions, promises, warranties or undertakings,
other than those set forth or referred to herein, with respect to the registration rights granted by the Company with respect to the Registrable Common Shares. No party hereto shall have any rights, duties or obligations other than those
specifically set forth in this Agreement. This Agreement supersedes all prior agreements and undertakings among the parties with respect to such registration rights. 
 26. Specific Performance. Without limiting the rights of each party hereto to pursue all other legal and equitable rights available to such party for any other parties’ failure to perform their obligations
under this Agreement, the parties hereto acknowledge and agree that the remedy at law for any failure to perform their obligations hereunder would be inadequate and that each of them, respectively, to the extent permitted by applicable law, shall be
entitled to specific performance, injunctive relief or other equitable remedies in the event of any such failure, without bond or other security being required. 
 27. Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason,
the parties shall negotiate in good faith with a view to the substitution therefor of a suitable and equitable solution in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid provision, provided,
however, that the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be in any way impaired thereby, it being intended that all of the rights and privileges
of the parties hereto shall be enforceable to the fullest extent permitted by law.

 Exhibit A 
 PLAN OF DISTRIBUTION 
 Securities may be sold or distributed from time to time by the selling
stockholders named in this prospectus and, to the extent permitted by their registration rights agreement with the Company, by their donees or transferees and their other successors in interest. The selling stockholders may sell their securities at
market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. Each selling stockholder reserves the right to accept or reject, in whole or in part,
any proposed purchase of securities, whether the purchase is to be made directly or through agents. 
 The selling stockholders may offer
their securities at various times in one or more of the following transactions, which may include an underwritten offering: 
  

	 	•	 	 in ordinary brokers’ transactions and transactions in which the broker solicits purchasers; 

  

	 	•	 	 in transactions involving cross or block trades or otherwise on the NASDAQ Global Select Market or any other national securities exchange on which the Common Stock
is listed; 

  

	 	•	 	 in transactions “at the market” to or through market makers in the common stock or into an existing market for the common stock;

  

	 	•	 	 in other ways not involving market makers or established trading markets, including direct sales of the securities to purchasers or sales of the securities effected
through agents; 

  

	 	•	 	 through transactions in options, swaps or other derivatives which may or may not be listed on an exchange; 

  

	 	•	 	 in privately negotiated transactions; or 

  

	 	•	 	 in a combination of any of the foregoing transactions. 

 The selling stockholders also may sell their securities in transactions which are exempt from registration under the Securities Act for which no prospectus is required to be delivered. 
 From time to time, one or more of the selling stockholders may pledge or grant a security interest in some or all of the securities owned by them. If the
selling stockholders default in performance of their secured obligations, the pledgees or secured parties may offer and sell the securities from time to time by this prospectus. The selling stockholders also may transfer and donate securities in
other circumstances. The amount of securities beneficially owned by selling stockholders will decrease as and when the selling stockholders transfer or donate their securities or default in performing obligations secured by their securities. The
plan of distribution for the securities offered and sold under this prospectus will otherwise remain unchanged, except that the transferees, donees, pledgees, other secured parties or other successors in interest will be selling stockholders for
purposes of this prospectus. 
  

 A-1 

 The selling stockholders may also enter into hedging transactions. For example, a selling stockholder
may: 
  

	 	•	 	 enter into transactions with a broker-dealer, affiliate thereof or other third party in connection with which such other party may engage in sales of their
securities pursuant to this prospectus, in which case such other party may use shares of the securities received from the selling stockholder to close out any short positions created; 

  

	 	•	 	 sell their securities short itself pursuant to this prospectus and use shares of their securities to close out its short positions; 

  

	 	•	 	 enter into option or other types of transactions that require the selling stockholder to deliver their securities to a broker-dealer or an affiliate thereof or
other third party, who may then resell or transfer the securities pursuant to this prospectus; or 

  

	 	•	 	 loan or pledge their securities to a broker-dealer or an affiliate thereof or other third party, who may sell the loaned securities or, in an event of default in
the case of a pledge, sell the pledged securities pursuant to this prospectus. 

 The selling stockholders may use brokers,
dealers, underwriters or agents to sell their securities. The persons acting as agents may receive compensation in the form of commissions, discounts or concessions. This compensation may be paid by the selling stockholders or the purchasers of the
securities of whom such persons may act as agent, or to whom they may sell as principal, or both. The compensation as to a particular person may be less than or in excess of customary commissions. Any agents or broker-dealers that participate in the
offer and sale of the securities may be deemed to be “underwriters” within the meaning of the Securities Act. Any commissions they receive and any profit they realize on the resale of the securities by them may be deemed to be underwriting
discounts and commissions under the Securities Act. Neither we nor any selling stockholders can presently estimate the amount of such compensation. 
 If a selling stockholder sells securities in an underwritten offering, the underwriters may acquire the securities for their own account and resell the securities from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined at the time of sale. In such event, we will set forth in a supplement to this prospectus the names of the underwriters and the terms of the transactions, including any
underwriting discounts, concessions or commissions and other items constituting compensation of the underwriters and broker-dealers. The underwriters from time to time may change any public offering price and any discounts, concessions or
commissions allowed or reallowed or paid to broker-dealers. Unless otherwise set forth in a supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to
purchase all of the securities specified in the supplement if they purchase any of the securities. 
 We have informed the selling
stockholders that during such time as they may be engaged in a distribution of the securities, they are required to comply with Regulation M under the Securities Exchange Act. With exceptions, Regulation M prohibits any selling stockholder, any
affiliated 

  

 A-2 

 
purchasers and other persons who participate in such a distribution from bidding for or purchasing, or attempting to induce any person to bid for or
purchase, any security which is the subject of the distribution until the entire distribution is complete. 
 This offering by any selling
stockholder will terminate on the date specified in the selling stockholder’s registration rights agreement with the Company, or, if earlier, on the date on which the selling stockholder has sold all of such selling stockholder’s
securities.
