 REGISTRATION RIGHTS 
 2.1 Demand Registration. 
 2.1.1 Request for Registration. 
 (a)
Commencing on the date hereof, any Holder or Holders of Registrable Shares shall have the right to require the Company to file a registration statement on Form S-1 or S-3 or any similar or successor to such forms under the Securities Act for a
public offering of all or part of its or their Registrable Shares (a “Demand Registration”), by delivering to the Company written notice stating that such right is being exercised, naming, if applicable, the Holders whose
Registrable Shares are to be included in such registration (collectively, the “Demanding Stockholders”), specifying the number of each such Demanding Stockholder’s Registrable Shares to be included in such registration and,
subject to Section 2.1.3 hereof, describing the intended method of distribution thereof (a “Demand Request”). The IPO Registration Statement shall not constitute a Demand Registration for any purpose under this Agreement.

 (b) Each Demand Request shall specify the aggregate number of Registrable Shares proposed to be sold. Subject to
Section 2.1.6, the Company shall file the registration statement in respect of a Demand Registration as soon as practicable and, in any event, within forty-five (45) days after receiving a Demand Request (the “Required
Filing Date”) and shall use reasonable best efforts to cause the same to be declared effective by the SEC as promptly as practicable after such filing; provided, however, that: 
 (i) the Company shall not be obligated to file a registration statement in respect of a Demand Registration pursuant 

  

 3 

 
to Section 2.1.1(a) (A) within sixty (60) days after the effective date of a previous Demand Registration, other than a Shelf Registration
pursuant to this Article 2, or (B) within one hundred and eighty (180) days after the effective date of the IPO Registration Statement; and 
 (ii) the Company shall not be obligated to file a registration statement in respect of a Demand Registration pursuant to Section 2.1.1(a) unless the Demand Request is for a number of Registrable Shares with a
market value that is equal to at least $10 million as of the date of such Demand Request. 
 2.1.2 Shelf Registration. With respect to
any Demand Registration, the Requesting Holders may request the Company to effect a registration of the Registrable Shares under a registration statement pursuant to Rule 415 under the Securities Act (or any successor rule) (a “Shelf
Registration”). 
 2.1.3 Selection of Underwriters. At the request of a majority of the Requesting Holders, the offering of
Registrable Shares pursuant to a Demand Registration shall be in the form of a “firm commitment” underwritten offering. The Holders of a majority of the Registrable Shares to be registered in a Demand Registration shall select the
investment banking firm or firms to manage the underwritten offering, provided that such selection shall be subject to the consent of the Company, which consent shall not be unreasonably withheld or delayed. No Holder may participate in any
registration pursuant to Section 2.1.1 unless such Holder (x) agrees to sell such Holder’s Registrable Shares on the basis provided in any underwriting arrangements described above and (y) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements; provided, however, that no such Holder shall be required to make any
representations or warranties in connection with any such registration other than representations and warranties as to (i) such Holder’s ownership of his or its Registrable Shares to be transferred free and clear of all liens, claims, and
encumbrances, (ii) such Holder’s power and authority to effect such transfer, and (iii) such matters pertaining to compliance with securities laws as may be reasonably requested; provided, further, however, that
the obligation of such Holder to indemnify pursuant to any such underwriting arrangements shall be several, not joint and several, among such Holders selling Registrable Shares, and the liability of each such Holder will be in proportion thereto,
and provided, further, that such liability will be limited to the net amount received by such Holder from the sale of his or its Registrable Shares pursuant to such registration. 
 2.1.4 Rights of Nonrequesting Holders. Upon receipt of any Demand Request, the Company shall promptly (but in any event within ten (10) days)
give written notice of such proposed Demand Registration to all other Holders, who shall have the right, exercisable by written notice to the Company within twenty (20) days of their receipt of the Company’s notice, to elect to include in
such Demand Registration such portion of their Registrable Shares as they may request. All Holders requesting to have 

  

 4 

 
their Registrable Shares included in a Demand Registration in accordance with the preceding sentence shall be deemed to be “Requesting Holders” for
purposes of this Section 2.1. 
 2.1.5 Priority on Demand Registrations. No securities to be sold for the account of any
Person (including the Company) other than a Requesting Holder shall be included in a Demand Registration unless the managing underwriter or underwriters shall advise the Requesting Holders in writing that the inclusion of such securities will not
adversely affect the price, timing or distribution of the offering or otherwise adversely affect its success (an “Adverse Effect”). Furthermore, if the managing underwriter or underwriters shall advise the Requesting Holders that,
even after exclusion of all securities of other Persons pursuant to the immediately preceding sentence, the amount of Registrable Shares proposed to be included in such Demand Registration by Requesting Holders is sufficiently large to cause an
Adverse Effect, the Registrable Shares of the Requesting Holders to be included in such Demand Registration shall equal the number of shares which the Requesting Holders are so advised can be sold in such offering without an Adverse Effect and such
shares shall be allocated pro rata among the Requesting Holders on the basis of the number of Registrable Shares requested to be included in such registration by each such Requesting Holder. 
 2.1.6 Deferral of Filing. The Company may defer the filing (but not the preparation) of a registration statement required by
Section 2.1 until a date not later than ninety (90) days after the Required Filing Date if (i) at the time the Company receives the Demand Request, the Company is engaged in confidential negotiations or other confidential
business activities, disclosure of which would be required in such registration statement (but would not be required if such registration statement were not filed), and the Board of Directors of the Company or a committee of the Board of Directors
of the Company determines in good faith that such disclosure would be materially detrimental to the Company and its shareholders, or (ii) prior to receiving the Demand Request, the Company had determined to effect a registered underwritten
public offering of the Company’s securities for the Company’s account and the Company had taken substantial steps (including, but not limited to, selecting a managing underwriter for such offering) and is proceeding with reasonable
diligence to effect such offering. A deferral of the filing of a registration statement pursuant to this Section 2.1.6 shall be lifted, and the requested registration statement shall be filed forthwith, if, in the case of a deferral
pursuant to clause (i) of the preceding sentence, the negotiations or other activities are disclosed or terminated, or, in the case of a deferral pursuant to clause (ii) of the preceding sentence, the proposed registration for the
Company’s account is abandoned. In order to defer the filing of a registration statement pursuant to this Section 2.1.6, the Company shall promptly (but in any event within ten (10) days), upon determining to seek such
deferral, deliver to each Requesting Holder a certificate signed by an executive officer of the Company stating that the Company is deferring such filing pursuant to this Section 2.1.6 and a general statement of the reason for such
deferral and an approximation of the anticipated delay. Within twenty (20) days after receiving such certificate, the holders of a majority of the Registrable Shares held by the Requesting Holders and for which registration was previously
requested may withdraw such Demand Request by giving notice to the Company; if withdrawn, the Demand Request shall be 

  

 5 

 
deemed not to have been made for all purposes of this Agreement. The Company may defer the filing of a particular registration statement pursuant to this
Section 2.1.6(a) only once. 
 2.2 Piggyback Registrations. 
 2.2.1 Right to Piggyback. Each time the Company proposes to register any of its equity securities (other than pursuant to an Excluded Registration)
under the Securities Act for sale to the public (whether for the account of the Company or the account of any securityholder of the Company) (a “Piggyback Registration”), the Company shall give prompt written notice to each Holder
of Registrable Shares (which notice shall be given not less than twenty (20) days prior to the anticipated filing date of the Company’s registration statement), which notice shall offer each such Holder the opportunity to include any or
all of its Registrable Shares in such registration statement, subject to the limitations contained in Section 2.2.2 hereof. Each Holder who desires to have its Registrable Shares included in such registration statement shall so advise
the Company in writing (stating the number of shares desired to be registered) within ten (10) days after the date of such notice from the Company. Any Holder shall have the right to withdraw such Holder’s request for inclusion of such
Holder’s Registrable Shares in any registration statement pursuant to this Section 2.2.1 by giving written notice to the Company of such withdrawal. Subject to Section 2.2.2 below, the Company shall include in such
registration statement all such Registrable Shares so requested to be included therein; provided, however, that the Company may at any time withdraw or cease proceeding with any such registration if it shall at the same time withdraw
or cease proceeding with the registration of all other equity securities originally proposed to be registered. 
 2.2.2 Priority on
Piggyback Registrations. 
 (a) If a Piggyback Registration is an underwritten offering and was initiated by the Company, and if the
managing underwriter advises the Company that the inclusion of Registrable Shares requested to be included in the Registration Statement would cause an Adverse Effect, the Company shall include in such registration statement (i) first, the
securities the Company proposes to sell, (ii) second, the Registrable Shares requested to be included in such registration, pro rata among the Holders of such Registrable Shares on the basis of the number of Registrable Shares owned by each
such Holder, and (iii) third, any other securities requested to be included in such registration. If as a result of the provisions of this Section 2.2.2(a) any Holder shall not be entitled to include all Registrable Shares in a
registration that such Holder has requested to be so included, such Holder may withdraw such Holder’s request to include Registrable Shares in such registration statement. 
 (b) If a Piggyback Registration is an underwritten offering and was initiated by a security holder of the Company, and if the managing underwriter
advises the Company that the inclusion of Registrable Shares requested to be included in the Registration Statement would cause an Adverse Effect, the Company shall include in such registration statement (i) first, the securities requested to
be included therein by the 

  

 6 

 
security holders requesting such registration and the Registrable Shares requested to be included in such registration, pro rata among the holders of such
securities on the basis of the number of securities owned by each such holder, and (ii) second, any other securities requested to be included in such registration (including securities to be sold for the account of the Company). If as a result
of the provisions of this Section 2.2.2(b) any Holder shall not be entitled to include all Registrable Shares in a registration that such Holder has requested to be so included, such Holder may withdraw such Holder’s request to
include Registrable Shares in such registration statement. 
 (c) No Holder may participate in any registration statement in respect of a
Piggyback Registration hereunder unless such Holder (x) agrees to sell such Holder’s Registrable Shares on the basis provided in any underwriting arrangements approved by the Company and (y) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents, each in customary form, reasonably required under the terms of such underwriting arrangements; provided, however, that no such Holder shall be required to
make any representations or warranties in connection with any such registration other than representations and warranties as to (i) such Holder’s ownership of his or its Registrable Shares to be sold or transferred free and clear of all
liens, claims, and encumbrances, (ii) such Holder’s power and authority to effect such transfer, and (iii) such matters pertaining to compliance with securities laws as may be reasonably requested; provided, further,
however, that the obligation of such Holder to indemnify pursuant to any such underwriting arrangements shall be several, not joint and several, among such Holders selling Registrable Shares, and the liability of each such Holder will be in
proportion to, and provided, further, that such liability will be limited to, the net amount received by such Holder from the sale of his or its Registrable Shares pursuant to such registration. 
 2.2.3 Selection of Underwriters. If any Piggyback Registration is an underwritten offering and any of the investment banking firms selected to
manage the offering was not one of the book-running managers of the IPO, any such investment banking firm shall not administer such offering if the Holders of a majority of the Registrable Shares included in such Piggyback Registration are ENV or
affiliates thereof and such Holders reasonably object thereto. 
 2.3 SEC Form S-3. The Company shall use its reasonable best efforts
to cause Demand Registrations to be registered on Form S-3 (or any successor form) once the Company becomes eligible to use Form S-3, and if the Company is not then eligible under the Securities Act to use Form S-3, Demand Registrations shall be
registered on the form for which the Company then qualifies. The Company shall use its reasonable best efforts to become eligible to use Form S-3 and, after becoming eligible to use Form S-3, shall use its reasonable best efforts to remain so
eligible. 
 2.4 Holdback Agreements. 
 (a) The Company shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the seven (7) days prior to
and during the ninety (90)-day period 

  

 7 

 
beginning on the effective date of any registration statement in connection with a Demand Registration (other than a Shelf Registration) or a Piggyback
Registration, except pursuant to registrations on Form S-4 or Form S-8 or any successor form or unless the underwriters managing any such public offering otherwise agree. 
 (b) If any Holders of Registrable Shares notify the Company in writing that they intend to effect an underwritten sale of Shares registered pursuant to
a Shelf Registration pursuant to Article 2 hereof, the Company shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for its equity securities, during the seven
(7) days prior to and during the ninety (90)-day period beginning on the date such notice is received, except pursuant to registrations on Form S-4 or Form S-8 or any successor form or unless the underwriters managing any such public offering
otherwise agree. 
 (c) Each Holder agrees, in the event of an underwritten offering by the Company (whether for the account of the Company
or otherwise), not to offer, sell, contract to sell or otherwise dispose of any Registrable Shares, or any securities convertible into or exchangeable or exercisable for such securities, including any sale pursuant to Rule 144 under the Securities
Act (except as part of such underwritten offering), during the seven (7) days prior to, and during the ninety (90)-day period (or such lesser period as the lead or managing underwriters may require) beginning on, the effective date of the
registration statement for such underwritten offering (or, in the case of an offering pursuant to an effective shelf registration statement pursuant to Rule 415, the pricing date for such underwritten offering). 
 2.5 Registration Procedures. Whenever any Holder has requested that any Registrable Shares be registered pursuant to this Agreement, the Company
will use its reasonable best efforts to effect the registration and the sale of such Registrable Shares in accordance with the intended method of disposition thereof as promptly as is practicable, and pursuant thereto the Company will as
expeditiously as possible: 
 (i) prepare and file with the SEC, pursuant to Section 2.1.1(b) with respect to any
Demand Registration, a registration statement on any appropriate form under the Securities Act with respect to such Registrable Shares and use its reasonable best efforts to cause such registration statement to become effective, provided that as far
in advance as practicable before filing such registration statement or any amendment thereto, the Company will furnish to the selling Holders copies of reasonably complete drafts of all such documents prepared to be filed (including exhibits), and
any such Holder shall have the opportunity to object to any information contained therein and the Company will make corrections reasonably requested by such Holder with respect to such information prior to filing any such registration statement or
amendment; 
 (ii) except in the case of a Shelf Registration, prepare and file with the SEC such amendments, post-effective
amendments, and supplements to such registration statement and the prospectus used in connection 

  

 8 

 
therewith as may be necessary to keep such registration statement effective for a period of not less than one hundred eighty (180) days (or such lesser
period as is necessary for the underwriters in an underwritten offering to sell unsold allotments) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during
such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement; 
 (iii) in the case of a Shelf Registration, prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement
effective and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Shares subject thereto for a period ending on the earlier of (x) twenty four (24) months after the effective date of such
registration statement and (y) the date on which all the Registrable Shares subject thereto have been sold pursuant to such registration statement; 
 (iv) furnish to each seller of Registrable Shares and the underwriters of the securities being registered such number of copies of such registration statement, each amendment and supplement thereto, the prospectus
included in such registration statement (including each preliminary prospectus), any documents incorporated by reference therein and such other documents as such seller or underwriters may reasonably request in order to facilitate the disposition of
the Registrable Shares owned by such seller or the sale of such securities by such underwriters (it being understood that, subject to Section 2.6 and the requirements of the Securities Act and applicable state securities laws, the
Company consents to the use of the prospectus and any amendment or supplement thereto by each seller and the underwriters in connection with the offering and sale of the Registrable Shares covered by the registration statement of which such
prospectus, amendment or supplement is a part); 
 (v) use its reasonable best efforts to register or qualify such
Registrable Shares under such other securities or blue sky laws of such jurisdictions as the managing underwriter reasonably requests (or, in the event the registration statement does not relate to an underwritten offering, as the holders of a
majority of such Registrable Shares may reasonably request); use its reasonable best efforts to keep each such registration or qualification (or exemption therefrom) effective during the period in which such registration statement is required to be
kept effective; and do any and all other acts and things which may be reasonably necessary or advisable to enable each seller to consummate the disposition of the Registrable Shares owned by such seller in such jurisdictions (provided,
however, that the Company will not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph or (B) consent to general service of process in
any such jurisdiction); 
  

 9 

 (vi) promptly notify each seller and each underwriter and (if requested by any such
Person) confirm such notice in writing (A) when a prospectus or any prospectus supplement or post-effective amendment has been filed and, with respect to a registration statement or any post-effective amendment, when the same has become
effective, (B) of the issuance by any state securities or other regulatory authority of any order suspending the qualification or exemption from qualification of any of the Registrable Shares under state securities or “blue sky” laws
or the initiation of any proceedings for that purpose, and (C) of the happening of any event which makes any statement made in a registration statement or related prospectus untrue or which requires the making of any changes in such
registration statement, prospectus or documents so that they will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and,
as promptly as practicable thereafter, prepare and file with the SEC and furnish a supplement or amendment to such prospectus so that, as thereafter deliverable to the purchasers of such Registrable Shares, such prospectus will not contain any
untrue statement of a material fact or omit a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; 
 (vii) permit any selling Holder, which in such Holder’s sole and exclusive judgment, might reasonably be deemed to be an underwriter
or a controlling person of the Company, to participate in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such
Holder and its counsel should be included; 
 (viii) make reasonably available members of management of the Company, as
selected by the Holders of a majority of the Registrable Shares included in such registration, for assistance in the selling effort relating to the Registrable Shares covered by such registration, including, but not limited to, the participation of
such members of the Company’s management in road show presentations; 
 (ix) otherwise use its reasonable best efforts
to comply with all applicable rules and regulations of the SEC, including the Securities Act and the Exchange Act and the rules and regulations promulgated thereunder, and make generally available to the Company’s securityholders an earnings
statement satisfying the provisions of Section 11(a) of the Securities Act no later than thirty (30) days after the end of the twelve (12) month period beginning with the first day of the Company’s first fiscal quarter commencing
after the effective date of a 

  

 10 

 
registration statement, which earnings statement shall cover said twelve (12) month period, and which requirement will be deemed to be satisfied if the
Company timely files complete and accurate information on Forms 10-K and 10-Q under the Exchange Act and otherwise complies with Rule 158 under the Securities Act; 
 (x) if requested by the managing underwriter or any seller promptly incorporate in a prospectus supplement or post-effective amendment
such information as the managing underwriter or any seller reasonably requests to be included therein, including, without limitation, with respect to the Registrable Shares being sold by such seller, the purchase price being paid therefor by the
underwriters and with respect to any other terms of the underwritten offering of the Registrable Shares to be sold in such offering, and promptly make all required filings of such prospectus supplement or post-effective amendment; 
 (xi) as promptly as practicable after filing with the SEC of any document which is incorporated by reference into a registration
statement (in the form in which it was incorporated), deliver a copy of each such document to each seller; 
 (xii) cooperate
with the sellers and the managing underwriter to facilitate the timely preparation and delivery of certificates (which shall not bear any restrictive legends unless required under applicable law) representing securities sold under any registration
statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or such sellers may request and keep available and make available to the Company’s transfer agent prior to the
effectiveness of such registration statement a supply of such certificates; 
 (xiii) promptly make available for inspection
by any seller, any underwriter participating in any disposition pursuant to any registration statement, and any attorney, accountant or other agent or representative retained by any such seller or underwriter (collectively, the
“Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”), as shall be reasonably necessary to enable them to exercise their due
diligence responsibility, and cause the Company’s officers, directors and employees to supply all information requested by any such Inspector in connection with such registration statement; provided, however, that, unless the
disclosure of such Records is necessary to avoid or correct a misstatement or omission in the registration statement or the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, the Company
shall not be required to provide any information under this subparagraph (x) if (A) the Company believes, after consultation with counsel for the Company, that to do so would cause the Company to forfeit an attorney-client privilege that
was applicable to such 

  

 11 

 
information or (B) if either (1) the Company has requested and been granted from the SEC confidential treatment of such information contained in
any filing with the SEC or documents provided supplementally or otherwise or (2) the Company reasonably determines in good faith that such Records are confidential and so notifies the Inspectors in writing, unless prior to furnishing any such
information with respect to clause (B) such Holder of Registrable Shares requesting such information agrees to enter into a confidentiality agreement in customary form and subject to customary exceptions; and provided, further,
that each Holder of Registrable Shares agrees that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at its expense, to undertake appropriate
action and to prevent disclosure of the Records deemed confidential; 
 (xiv) furnish to each seller and underwriter a signed
counterpart of (A) an opinion or opinions of counsel to the Company, and (B) a comfort letter or comfort letters from the Company’s independent public accountants, each in customary form and covering such matters of the type
customarily covered by opinions or comfort letters, as the case may be, as the sellers or managing underwriter reasonably requests; 
 (xv) cause the Registrable Shares included in any registration statement to be (A) listed on each securities exchange, if any, on which similar securities issued by the Company are then listed, or (B) quoted on the Financial
Industry Regulatory Authority’s Automated Quotation System or the Nasdaq National Market if similar securities issued by the Company are quoted thereon; 
 (xvi) provide a transfer agent and registrar for all Registrable Shares registered hereunder; 
 (xvii) cooperate with each seller and each underwriter participating in the disposition of such Registrable Shares and their respective
counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority (“FINRA”); 
 (xviii) during the period when the prospectus is required to be delivered under the Securities Act, promptly file all documents required to be filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the
Exchange Act; 
 (xix) notify each seller of Registrable Shares promptly of any request by the SEC for the amending or
supplementing of such registration statement or prospectus or for additional information; 
  

 12 

 (xx) enter into such agreements (including underwriting agreements in the managing
underwriter’s customary form) as are customary in connection with an underwritten registration; and 
 (xxi) advise each
seller of such Registrable Shares, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the SEC suspending the effectiveness of such registration statement or the initiation or threatening of any
proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued. 
 2.6 Suspension of Dispositions. Each Holder agrees by acquisition of any Registrable Shares that, upon receipt of any notice (a
“Suspension Notice”) from the Company of the happening of any event of the kind described in Section 2.5(vi)(C) such Holder will forthwith discontinue disposition of Registrable Shares until such Holder’s receipt of
the copies of the supplemented or amended prospectus, or until it is advised in writing (the “Advice”) by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in the prospectus, and, if so directed by the Company, such Holder will deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such
Registrable Shares current at the time of receipt of such notice. In the event the Company shall give any such notice, the time period regarding the effectiveness of registration statements set forth in Sections 2.5(ii) and 2.5(iii)
hereof shall be extended by the number of days during the period from and including the date of the giving of the Suspension Notice to and including the date when each seller of Registrable Shares covered by such registration statement shall have
received the copies of the supplemented or amended prospectus or the Advice. The Company shall use its reasonable best efforts and take such actions as are reasonably necessary to render the Advice as promptly as practicable. 
 2.7 Registration Expenses. All fees and expenses incident to any registration including, without limitation, the Company’s performance of or
compliance with this Article 2, all registration and filing fees, all fees and expenses associated with filings required to be made with FINRA (including, if applicable, the reasonable fees and expenses of any “qualified independent
underwriter” as such term is defined in Schedule E of the By-Laws of FINRA, and of its counsel), as may be required by the rules and regulations of FINRA, fees and expenses of compliance with securities or “blue sky” laws (including
reasonable fees and disbursements of counsel in connection with “blue sky” qualifications of the Registrable Shares), rating agency fees, printing expenses (including expenses of printing certificates for the Registrable Shares in a form

 13 

 
registration, and the fees and expenses of other persons retained by the Company, will be borne by the Company (unless paid by a security holder that is not
a Holder for whose account the registration is being effected) whether or not any registration statement becomes effective; provided, however, that any underwriting discounts, commissions, or fees attributable to the sale of the
Registrable Shares will be borne by the Holders pro rata on the basis of the number of shares so registered and the fees and expenses of any counsel, accountants, or other persons retained or employed by any Holder will be borne by such Holder.

 2.8 Indemnification. 
 2.8.1 The Company agrees to indemnify and reimburse, to the fullest extent permitted by law, each seller of Registrable Shares, and each of its employees, advisors, agents, representatives, partners, officers, and directors and each Person
who controls such seller (within the meaning of the Securities Act or the Exchange Act) and any agent or investment advisor thereof (collectively, the “Seller Affiliates”) (A) against any and all losses, claims, damages,
liabilities, and expenses, joint or several (including, without limitation, attorneys’ fees and disbursements except as limited by Section 2.8.3) based upon, arising out of, related to or resulting from any untrue or alleged untrue
statement of a material fact contained in any registration statement, prospectus, preliminary prospectus, issuer free writing prospectus (as such term is defined in Rule 433 of the Securities Act) or any amendment thereof or supplement thereto, or
any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, (B) against any and all loss, liability, claim, damage, and expense whatsoever, as incurred, to the
extent of the aggregate amount paid in settlement of any litigation or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon, arising out of, related to or resulting from any
such untrue statement or omission or alleged untrue statement or omission, and (C) against any and all costs and expenses (including reasonable fees and disbursements of counsel) as may be reasonably incurred in investigating, preparing, or
defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or
alleged untrue statement or omission, or such violation of the Securities Act or Exchange Act, to the extent that any such expense or cost is not paid under subparagraph (A) or (B) above; except insofar as any such statements are made in
reliance upon and in strict conformity with information furnished in writing to the Company by such seller or any Seller Affiliate for use therein or arise from such seller’s or any Seller Affiliate’s failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such seller or Seller Affiliate with a sufficient number of copies of the same. The reimbursements required by this
Section 2.8.1 will be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. 
 2.8.2 In connection with any registration statement in which a seller of Registrable Shares is participating, each such seller will furnish to the Company in 

  

 14 

 
writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to
the fullest extent permitted by law, each such seller will indemnify the Company and each of its employees, advisors, agents, representatives, partners, officers and directors and each Person who controls the Company (within the meaning of the
Securities Act or the Exchange Act) and any agent or investment advisor thereof against any and all losses, claims, damages, liabilities, and expenses (including, without limitation, reasonable attorneys’ fees and disbursements except as
limited by Section 2.8.3) resulting from any untrue statement or alleged untrue statement of a material fact contained in the registration statement, prospectus, or any preliminary prospectus or any amendment thereof or supplement
thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or
alleged omission is contained in any information or affidavit so furnished in writing by such seller or any of its Seller Affiliates specifically for inclusion in the registration statement; provided that the obligation to indemnify will be
several, not joint and several, among such sellers of Registrable Shares, and the liability of each such seller of Registrable Shares will be in proportion to, and will be limited to, the net amount received by such seller from the sale of
Registrable Shares pursuant to such registration statement; provided, however, that such seller of Registrable Shares shall not be liable in any such case to the extent that prior to the filing of any such registration statement or
prospectus or amendment thereof or supplement thereto, such seller has furnished in writing to the Company information expressly for use in such registration statement or prospectus or any amendment thereof or supplement thereto which corrected or
made not misleading information previously furnished to the Company. 
 2.8.3 Any Person entitled to indemnification hereunder will
(A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give such notice shall not limit the rights of such Person) and (B) unless in such
indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party; provided, however, that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses
of such counsel shall be at the expense of such person unless (X) the indemnifying party has agreed to pay such fees or expenses, or (Y) the indemnifying party shall have failed to assume the defense of such claim and employ counsel
reasonably satisfactory to such person. If such defense is not assumed by the indemnifying party as permitted hereunder, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent
(but such consent will not be unreasonably withheld). If such defense is assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim unless (1) such
settlement or compromise contains a full and unconditional release of the indemnified party or (2) the indemnified party otherwise consents in writing. An indemnifying party who is not entitled to, or elects not to, assume the defense of a
claim will not be obligated to pay the fees and expenses of more 

  

 15 

 
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, a conflict of interest may exist between such 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 reasonable fees and disbursements of
such additional counsel or counsels. 
 2.8.4 Each party hereto agrees that, if for any reason the indemnification provisions contemplated by
Section 2.8.1 or Section 2.8.2 are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities, or expenses (or actions in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, liabilities, or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection with the actions which resulted in the losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of
such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact 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 statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 2.8.4 were determined by pro rata allocation (even if the Holders or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in this Section 2.8.4. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities, or expenses (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or, except as provided in Section 2.8.3, defending any such action
or claim. Notwithstanding the provisions of this Section 2.8.4, no Holder shall be required to contribute an amount greater than the dollar amount by which the net proceeds received by such Holder with respect to the sale of any
Registrable Shares exceeds the amount of damages which such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any
registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto related to such sale of Registrable Shares. 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 Holders’ obligations in this Section 2.8.4 to contribute shall be several in proportion to the amount of
Registrable Shares registered by them and not joint. 
 If indemnification is available under this Section 2.8, the indemnifying
parties shall indemnify each indemnified party to the full extent provided in Section 2.8.1 and Section 2.8.2 without regard to the relative fault of said indemnifying party or indemnified party or any other equitable
consideration provided for in this Section 2.8.4 subject, in the case of the Holders, to the limited dollar amounts set forth in Section 2.8.2. 
  

 16 

 2.8.5 The indemnification and contribution provided for under this Agreement will remain in full force
and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, or controlling Person of such indemnified party and will survive the transfer of securities. 
 2.9 Transfer of Registration Rights. The rights of each Holder under this Agreement may be assigned to any direct or indirect transferee of a
Holder who agrees in writing to be subject to and bound by all the terms and conditions of this Agreement. 
 2.10 Rule 144. The
Company will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder (or, if the Company is not required to file such reports, will, upon the request of
the Holders, make publicly available other information) and will take such further action as the Holders may reasonably request, all to the extent required from time to time to enable the Holders to sell Shares without registration under the
Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such rule may be amended from time to time or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the
reasonable request of any Holder, the Company will deliver to such parties a written statement as to whether it has complied with such requirements and will, at its expense, forthwith upon the request of any such Holder, deliver to such Holder a
certificate, signed by the Company’s principal financial officer, stating (a) the Company’s name, address and telephone number (including area code), (b) the Company’s Internal Revenue Service identification number,
(c) the Company’s SEC file number, (d) the number of shares of each class of capital stock outstanding as shown by the most recent report or statement published by the Company, and (e) whether the Company has filed the reports
required to be filed under the Exchange Act for a period of at least ninety (90) days prior to the date of such certificate and in addition has filed the most recent annual report required to be filed thereunder. 
 2.11 Preservation of Rights. The Company will not (i) grant any registration rights to third parties which are more favorable than or
inconsistent with the rights granted hereunder or (ii) enter into any agreement, take any action, or permit any change to occur, with respect to its securities that violates or subordinates the rights expressly granted to the Holders in this
Agreement. 
 ARTICLE 3 
 TERMINATION 
 3.1 Termination. The Holders may exercise the registration rights granted hereunder in such
manner and proportions as they shall agree among themselves. The registration rights hereunder shall cease to apply to any particular Registrable Share when: (a) a registration statement with respect to the sale of such Shares (or other
securities) shall have become effective under the Securities Act and such Shares shall have been disposed of in accordance with such registration statement; (b) such Shares (or 

  

 17 

 
other securities) shall have been sold to the public pursuant to Rule 144 under the Securities Act (or any successor provision); (c) such Shares (or
other securities) shall have been otherwise transferred, new certificates for them not bearing a legend restricting further transfer shall have been delivered by the Company and subsequent public distribution of them shall not require registration
or qualification of them under the Securities Act or any similar state law then in force; (d) such Shares (or other securities) shall have ceased to be outstanding or (e) in the case of Registrable Shares held by a Holder that is not ENV
or any affiliate thereof, such Holder holds less than three percent (3%) of the then outstanding Registrable Shares and such Registrable Shares are eligible for sale pursuant to Rule 144(k) under the Securities Act (or any successor provision).
The Company shall promptly upon the request of any Holder furnish to such Holder evidence of the number of Registrable Shares then outstanding.

 Exhibit 10.21 
 FORM OF DIRECTOR INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement
(“Agreement”) is made as of November __, 2007 by and between EnergySolutions, Inc., a Delaware corporation (the “Company”), and
                     (“Indemnitee”). 
 RECITALS 
 WHEREAS, highly competent persons have become more reluctant to serve publicly-held
corporations as directors or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and
activities on behalf of the corporation; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in
order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the
furnishing of such insurance has been a customary and widespread practice among U.S.-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in
the future only with certain exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other
things, matters that traditionally would have been brought only against the Company or business enterprise itself. The By-laws and Certificate of Incorporation of the Company require indemnification of the officers and directors of the Company.
Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”). The By-laws, Certificate of Incorporation and the DGCL expressly provide that the indemnification provisions
set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors and other persons with respect to indemnification; 
 WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons;

 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best
interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of,
such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 
 WHEREAS, this Agreement is a supplement to and in furtherance of the By-laws and Certificate of Incorporation of the Company and any resolutions adopted
pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 

 WHEREAS, Indemnitee does not regard the protection available under the Company’s By-laws and
insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to
serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; and 
 NOW, THEREFORE, in
consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows: 
 Section 1. Services to the Company. Indemnitee agrees to serve as a director of the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation
imposed by operation of law), in which event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries
or any Enterprise) and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s service to the Company (or any of its subsidiaries or any Enterprise), if any, is at will, and the Indemnitee may be discharged at any time for any
reason, with or without cause, except as may be otherwise provided in any written employment contract between Indemnitee and the Company (or any of its subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the
Board, or, with respect to service as a director or officer of the Company, by the Company’s Certificate of Incorporation, the Company’s By-laws, and the DGCL. The foregoing notwithstanding, this Agreement shall continue in force after
Indemnitee has ceased to serve as a director of the Company. 
 Section 2. Definitions. As used in this Agreement: 
 (a) A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any of the following events:

 i. Acquisition of Stock by Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined below), directly or
indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting power of the Company’s then outstanding securities; 
 ii. Change in Board. During any period of two (2) consecutive years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board, and
any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in Sections 2(a)(i), 2(a)(iii) or 2(a)(iv)) whose election by the Board or nomination for election by
the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved,
cease for any reason to constitute at least a majority of the members of the Board; 
 iii. Corporate Transactions. The effective date of a
merger or consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent
(either by remaining outstanding or by being 

  

 2 

 
converted into voting securities of the surviving entity) more than 51% of the combined voting power of the voting securities of the surviving entity
outstanding immediately after such merger or consolidation and with the power to elect at least a majority of the board of directors or other governing body of such surviving entity; 
 iv. Liquidation. The approval by the stockholders of the Company of a complete liquidation of the Company or an agreement for the sale or disposition by
the Company of all or substantially all of the Company’s assets; and 
 v. Other Events. There occurs any other event of a nature that
would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item on any similar schedule or form) promulgated under the Exchange Act (as defined below), whether or not the Company is
then subject to such reporting requirement. 
 For purposes of this Section 2(a), the following terms shall have the following meanings: 
 (A) “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended. 
 (B) “Person” shall have the meaning as set forth in Sections 13(d) and 14(d) of the Exchange Act; provided, however, that Person
shall exclude (i) the Company, (ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company, and (iii) any corporation owned, directly or indirectly, by the stockholders of the Company in
substantially the same proportions as their ownership of stock of the Company. 
 (C) “Beneficial Owner” shall have
the meaning given to such term in Rule 13d-3 under the Exchange Act; provided, however, that Beneficial Owner shall exclude any Person otherwise becoming a Beneficial Owner by reason of the stockholders of the Company approving a merger of the
Company with another entity. 
 (b) “Corporate Status” describes the status of a person who is or was a director, officer, employee
or agent of the Company or of any other corporation, limited liability company, partnership or joint venture, trust, employee benefit plan or other enterprise which such person is or was serving at the request of the Company. 
 (c) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in respect of which
indemnification is sought by Indemnitee. 
 (d) “Enterprise” shall mean the Company and any other corporation, limited liability
company, partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary. 
  

 3 

 (e) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs,
transcript costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, and all other disbursements or expenses of the types customarily incurred in
connection with prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing to be a witness in, or otherwise participating in, a Proceeding. Expenses also shall include (i) Expenses incurred in connection with
any appeal resulting from any Proceeding, including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent, and (ii) for purposes of Section 13(d)
only, Expenses incurred by Indemnitee in connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement, by litigation or otherwise. Expenses, however, shall not include amounts paid in settlement by
Indemnitee or the amount of judgments or fines against Indemnitee. 
 (f) “Independent Counsel” means a law firm, or a member of a
law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect
to matters concerning the Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the
foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an
action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims,
liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 
 (g) The term
“Proceeding” shall include any threatened, pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding,
whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative legislative, or investigative nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party, potential
party, non-party witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the Company, by reason of any action taken by him or of any action on his part while acting as director or officer of the Company, or by
reason of the fact that he is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, limited liability company, partnership, joint venture, trust or other enterprise, in each case whether or
not serving in such capacity at the time any liability or expense is incurred for which indemnification, reimbursement, or advancement of expenses can be provided under this Agreement; except one initiated by an Indemnitee to enforce his rights
under this Agreement. 
 (h) References to “other enterprise” shall include employee benefit plans; references to “fines”
shall include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director of the Company which imposes duties on, or involves services by,
such director with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the best interests of the participants and beneficiaries of an employee
benefit plan shall be deemed to have acted in manner “not opposed to the best interests of the Company” as referred to in this Agreement.

 Section 3. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in
accordance with the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor.
Pursuant to this Section 3, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his behalf
in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal proceeding
had no reasonable cause to believe that his conduct was unlawful. 
 Section 4. Indemnity in Proceedings by or in the Right of the
Company. The Company shall indemnify Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a
judgment in its favor. Pursuant to this Section 4, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by him or on his behalf in connection with such
Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this
Section 4 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery or any court in which the
Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 
 Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of this
Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein,
in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or
otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each successfully
resolved claim, issue or matter. If the Indemnitee is not wholly successful in such Proceeding, the Company also shall indemnify Indemnitee against all Expenses reasonably incurred in connection with a claim, issue or matter related to any claim,
issue, or matter on which the Indemnitee was successful. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a
successful result as to such claim, issue or matter. 
 Section 6. Indemnification For Expenses of a Witness. Notwithstanding any
other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent 

  

 5 

 
that Indemnitee is, by reason of his Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all
Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 
 Section 7. Additional
Indemnification. 
 (a) Notwithstanding any limitation in Sections 3, 4, or 5, the Company shall indemnify Indemnitee to the fullest
extent permitted by applicable law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines
and amounts paid in settlement actually and reasonably incurred by Indemnitee in connection with the Proceeding. 
 (b) For purposes of
Section 7(a), the meaning of the phrase “to the fullest extent permitted by applicable law” shall include, but not be limited to: 
 i. to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL, and 
 ii. to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that
increase the extent to which a corporation may indemnify its officers and directors. 
 Section 8. Exclusions. Notwithstanding
any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy
or other indemnity provision; or 
 (b) for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by
Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act (as defined in Section 2(a) hereof) or similar provisions of state statutory law or common law, or (ii) any reimbursement of the Company
by the Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such
reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale
by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act), or 
 (c) except as provided in Section 13(d) of
this Agreement, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or
other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the
Company under applicable law.

 Section 9. Advances of Expenses. In accordance with the existing requirements of
Section 3 of Article VI of the By-laws of the Company, and notwithstanding any provision of this Agreement to the contrary, the Company shall advance, to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection with
any Proceeding, and such advancement shall be made within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding.
Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of
this Agreement. Advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed.
The Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that the Indemnitee undertakes to repay the advance to the extent that it is ultimately
determined that Indemnitee is not entitled to be indemnified by the Company. This Section 9 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 8. 
 Section 10. Procedure for Notification and Defense of Claim. 
 (a) Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek indemnification or advancement of Expenses hereunder as soon as reasonably practicable following the
receipt by Indemnitee of written notice thereof. The written notification to the Company shall include a description of the nature of the Proceeding and the facts underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee
shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to
indemnification following the final disposition of such action, suit or proceeding. The omission by Indemnitee to notify the Company hereunder will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise
than under this Agreement, and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification,
advise the Board in writing that Indemnitee has requested indemnification. 
 (b) The Company will be entitled to participate in the
Proceeding at its own expense. 
 Section 11. Procedure Upon Application for Indemnification. 
 (a) Upon written request by Indemnitee for indemnification pursuant to Section 10(a), a determination, if required by applicable law, with respect to
Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or
(ii) if a Change in Control shall not have occurred, (A) by a majority 

  

 7 

 
vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority
vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy
of which shall be delivered to Indemnitee or (D) if so directed by the Board, by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten
(10) days after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity
upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses
(including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s
entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 
 (b) In the event the
determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 11(a) hereof, the Independent Counsel shall be selected as provided in this Section 11(b). If a Change in Control shall not have
occurred, the Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the
Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of
the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver to the Company or to
Indemnitee, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of
“Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as
Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is
without merit. If, within twenty (20) days after the later of submission by Indemnitee of a written request for indemnification pursuant to Section 10(a) hereof and the final disposition of the Proceeding, no Independent Counsel shall have
been selected and not objected to, either the Company or Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent
Counsel and/or for the appointment as Independent Counsel of a person selected by the Court or by such other person as the Court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act
as Independent Counsel under Section 11(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 13(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 
  

 8 

 Section 12. Presumptions and Effect of Certain Proceedings. 
 (a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall,
to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 10(a) of this Agreement, and the
Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure
of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met
the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a
presumption that Indemnitee has not met the applicable standard of conduct. 
 (b) Subject to Section 13(e), if the person, persons or
entity empowered or selected under Section 11 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor,
the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law;
provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in good
faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 12(b) shall not apply (i) if the determination
of entitlement to indemnification is to be made by the stockholders pursuant to Section 11(a) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the Board has
resolved to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of
stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made
thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 11(a) of this Agreement. 
 (c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise
expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the
best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. 
  

 9 

 (d) Reliance as Safe Harbor. For purposes of any determination of good faith, Indemnitee shall be
deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of
their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with the reasonable
care by the Enterprise. The provisions of this Section 12(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in
this Agreement. 
 (e) Actions of Others. The knowledge and/or actions, or failure to act, of any director, officer, agent or employee
of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 
 Section 13. Remedies of Indemnitee. 
 (a) Subject to Section 13(e), in the event that (i) a determination is
made pursuant to Section 11 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 9 of this Agreement, (iii) no
determination of entitlement to indemnification shall have been made pursuant to Section 11(a) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification
is not made pursuant to Section 5 or 6 or the last sentence of Section 11(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to
Section 3, 4 or 7 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any other person takes or threatens to
take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee
hereunder, Indemnitee shall be entitled to an adjudication by a court of his entitlement to such indemnification or advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an award in arbitration to be conducted by a single
arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee
first has the right to commence such proceeding pursuant to this Section 13(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his rights under
Section 5 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 
 (b) In the event that a determination shall have been made pursuant to Section 11(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this
Section 13 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant
to this Section 13 the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 
  

 10 

 (c) If a determination shall have been made pursuant to Section 11(a) of this Agreement that
Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a material fact, or an
omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 
 (d) The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced
pursuant to this Section 13 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of
this Agreement. It is the intent of the Company that the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or
otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee,
shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by law, such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by
Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is
determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 
 (e) Notwithstanding
anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 Section 14. Non-exclusivity; Survival of Rights; Insurance; Subrogation. 
 (a) The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights
to which Indemnitee may at any time be entitled under applicable law, the Company’s Certificate of Incorporation, the Company’s By-laws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. No amendment,
alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his Corporate Status prior to such amendment,
alteration or repeal. To the extent that a change in Delaware, U.S. federal or other law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be afforded currently under the Company’s
By-laws, Certificate of Incorporation and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be
exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 
  

 11 

 (b) To the extent that the Company maintains an insurance policy or policies providing liability
insurance for directors, officers, employees, or agents of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person serves at the request of the Company, Indemnitee shall
be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies. If, at the time of the receipt of a notice
of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in
the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such
policies. 
 (c) In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of
the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

 (d) The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable (or for which advancement
is provided hereunder) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 
 (e) The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a
director, officer, employee or agent of any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee has actually received as indemnification
or advancement of Expenses from such other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise. 
 Section 15. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten (10) years after the date that Indemnitee shall have ceased to serve as a of the
Company or (b) one (1) year after the final termination of any Proceeding then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee
pursuant to Section 13 of this Agreement relating thereto. This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and his heirs, executors and administrators. 
 Section 16. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any
reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid,
illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or provisions shall be
deemed reformed to the extent necessary to 

  

 12 

 
conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of
this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as
to give effect to the intent manifested thereby. 
 Section 17. Enforcement. 
 (a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce
Indemnitee to serve as a director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director of the Company. 
 (b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the
parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation of the Company, the By-laws of the Company and applicable law, and shall not
be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 
 Section 18. Modification and
Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by the parties thereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other
provisions of this Agreement nor shall any waiver constitute a continuing waiver. 
 Section 19. Notice by Indemnitee. Indemnitee
agrees promptly to notify the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement
of Expenses covered hereunder. The failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise. 
 Section 20. Notices. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be
deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) mailed by certified or registered mail with postage prepaid, on the third
business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been directed or (d) sent by facsimile transmission, with
receipt of oral confirmation that such transmission has been received: 
 (a) If to Indemnitee, at the address indicated on the signature page
of this Agreement, or such other address as Indemnitee shall provide to the Company. 
  

 13 

 (b) If to the Company to 423 West 300 South, Suite 200, Salt Lake City, Utah 84101, Telecopy No.:
(801) 321-0453, Attn: General Counsel, or to any other address as may have been furnished to Indemnitee by the Company. 
 Section 21. Contribution. To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying
Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event
under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s)
and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 Section 22. Applicable Law and Consent to Jurisdiction. This Agreement and the legal relations among the parties shall be governed by, and
construed and enforced in accordance with, the laws of the State of Delaware. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 13(a) of this Agreement, the Company and Indemnitee hereby irrevocably and
unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Chancery Court of the State of Delaware (the “Delaware Court”), and not in any other state or
federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this
Agreement, (iii) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court, and (iv) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware
Court has been brought in an improper or inconvenient forum. 
 Section 23. Identical Counterparts. This Agreement may be
executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability
is sought needs to be produced to evidence the existence of this Agreement. 
 Section 24. Miscellaneous. Use of the masculine
pronoun shall be deemed to include usage of the feminine pronoun where appropriate. The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the
construction thereof.
