 (a) If the Company shall receive at any time after the earlier of
(i) 5 years after the date of this Agreement or (ii) 180 days after the effective date of the first registration statement for a public offering of securities of the Company (other than a registration statement relating either to the sale
of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or a SEC Rule 145 transaction), a written request from the Holders who hold in excess of thirty percent (30%) of the Registrable Securities
then outstanding that the Company file a registration statement under the Securities Act covering the registration of the Registrable Securities then outstanding with an anticipated aggregate offering price (net of underwriting discounts and
commissions) of at least Ten Million Dollars ($10,000,000), then the Company shall: 
 (i) within ten (10) days of the
receipt thereof, give written notice of such request to all Holders; 
 (ii) as soon as practicable, and in any event within
sixty (60) days of the receipt of such request, file a registration statement under the Securities Act covering all Registrable Securities which the Holders request to be registered, subject to the limitations of subsection 2.1(b),
within twenty (20) days of the mailing of such notice by the Company in accordance with Section 6.5; and 
 (iii) use its best efforts to cause such registration statement to be declared effective by the SEC as soon as practicable. 
 (b)
If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to subsection 2.1 (a) and the
Company shall include such information in the written notice referred to in subsection 2.1(a). The underwriter will be selected by the Company and shall be reasonably acceptable to a majority in interest of the Initiating Holders. In such
event, the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s 

  

 4 

 
participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 2.3(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected
for such underwriting. Notwithstanding any other provision of this Section 2.1, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the
Initiating Holders shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all
Holders of Registrable Securities, including the Initiating Holders, in proportion (as nearly as practicable) to the number of Registrable Securities of the Company owned by each Holder; provided, however, that the number of shares of
Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. To facilitate the allocation of shares in accordance with the above
provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. 
 (c) The
Company shall not be obligated to effect, or to take any action to effect, any registration 
 (i) pursuant to this Section
2.1: 
 (i) In any particular jurisdiction in which the Company would be required to execute a general consent to service
of process in effecting such registration, unless the Company is already subject to service in such jurisdiction and except as may be required under the Securities Act; 
 (ii) After the Company has effected two (2) registrations pursuant to this Section 2.1 and such registrations have been
declared or ordered effective; 
 (iii) If the Initiating Holders propose to dispose of shares of Registrable Securities that
may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.11, below; or 
 (iv)
If the Registrable Securities to be included in the registration statement could be sold without restriction under SEC Rule 144(k) within a ninety (90) day period and the Company is currently subject to the periodic reporting requirements of
Sections 12(g) or 15(d) of the Exchange Act, or 
 (ii) pursuant to any other provision of this Agreement: 
 (i) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting
such registration, unless the Company is already subject to service in such jurisdiction and except as may be required under the Securities Act; or 
 (ii) If the Registrable Securities to be included in the registration statement could be sold without restriction under SEC Rule 144(k) within a ninety (90) day period and the Company is currently subject to the
periodic reporting requirements of Sections 12(g) or 15(d) of the Exchange Act. 
  

 5 

 (d) Notwithstanding the foregoing, if the Company shall furnish to Holders requesting a registration
statement pursuant to this Section 2.1 a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board it would be materially detrimental to the Company and its stockholders for
such registration statement to be filed and it is therefore necessary to defer the filing of such registration statement, the Company shall have the right to defer taking action with respect to such filing for a period of not more than ninety
(90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve-month period. 
 A registration statement shall not be counted until such time as such registration statement has been declared effective by the SEC (unless the
Initiating Holders withdraw their request for such registration (other than as a result of information concerning the business or financial condition of the Company which is made known to the Investors after the date on which such registration was
requested) and elect not to pay the registration expenses therefor pursuant to Section 2.5). A registration statement shall not be counted if, as a result of an exercise of the underwriter’s cut-back provisions, fewer than
seventy-five percent (75%) of the total number of Registrable Securities that Holders have requested to be included in such registration statement are actually included. 
 2.2. Company Registration. If the Company proposes to register (including for this purpose a registration effected by the Company for stockholders
other than the Holders) any of its stock or other securities under the Securities Act in connection with the public offering of such securities solely for cash (other than a registration statement relating either to the sale of securities to
employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction, a registration on any form which does not include substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities which are also being registered), the Company shall,
at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 6.6, the
Company shall, subject to the provisions of Section 2.7, cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered. The Company shall have the right to
terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The expenses of such
withdrawn registration shall be borne by the Company in accordance with Section 2.6, hereof. 
 2.3. Obligations of the
Company. Whenever required under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible, 
 (a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its reasonable best efforts to cause such
registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days
or, if earlier, until the distribution contemplated in the Registration Statement has been completed; provided, however, that (i) such 120-day period shall be extended for a period of time equal to the period the Holder refrains
from selling any securities included in such registration at the request of an underwriter of Common Stock (or other securities) of the Company; and (ii) in the case of any registration of Registrable Securities on Form S-3 which are intended
to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such 120-day period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold;

  

 6 

 (b) prepare and file with the SEC such amendments and supplements to such registration statement and the
prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement; 
 (c) furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them; 
 (d) use its reasonable best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by
the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdiction and except as may be required by the Securities Act; 
 (e) in the event of any underwritten
public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform
its obligations under such an agreement; 
 (f) cause all such Registrable Securities registered pursuant to this Agreement hereunder to be
listed on a national securities exchange or trading system and each securities exchange and trading system on which similar securities issued by the Company are then listed; 
 (g) provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of such registration; 
 (h) use its reasonable best efforts to furnish, at the
request of any Holder requesting registration of Registrable Securities pursuant to this Section 2, on the date on which such Registrable Securities are sold to the underwriter, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a “comfort” letter dated
such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters,
if any. 
 2.4. Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant
to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of
disposition of such securities as shall be reasonably required to effect the registration of such Holder’s Registrable Securities. 
 2.5. Expenses of Demand Registration. All expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant to Section 2.1, including (without
limitation) all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel for the selling Holders, shall be borne by
the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.1 

  

 7 

 
if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which
case all participating Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless the Holders of a majority of the Registrable Securities agree to forfeit
their right to one demand registration pursuant to Section 2. 
 2.6. Expenses of Company Registration. The Company shall
bear and pay all expenses incurred in connection with any registration, filing or qualification of Registrable Securities with respect to the registrations pursuant to Section 2.2 hereof for each Holder (which right may be assigned as
provided in Section 6.2 hereof), including (without limitation) all registration, filing, and qualification fees, printers and accounting fees relating or apportionable thereto and the fees and disbursements of one counsel for the
selling Holders selected by them, but excluding underwriting discounts and commissions relating to Registrable Securities. 
 2.7.
Underwriting Requirements. In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to Section 2.2, the Company shall not be required to include any of the Holders’
securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the
success of the offering by the Company subject to the limitations set forth below. If the total number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the amount of securities to be
sold other than by the Company that the underwriters determine in their reasonable discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities,
including Registrable Securities, which the underwriters and the Company determine in their sole discretion will not jeopardize the success of the offering. In no event shall any Registrable Securities be excluded from such offering unless all other
stockholders’ securities have been first excluded. In the event that the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that
are included in such offering shall be apportioned pro rata among the selling Holders based on the number of Registrable Securities held by all selling Holders or in such other proportions as shall mutually be agreed to by all such selling Holders.
Notwithstanding the foregoing, in no event shall the amount of securities of the selling Holders included in the offering be reduced below thirty percent (30%) of the total amount of securities included in such offering, unless such offering is
the Company’s IPO in which case the selling Holders may be excluded beyond this amount if the underwriters make the determination described above and no other stockholder’s securities are included in such offering. For purposes of the
preceding parenthetical concerning apportionment, for any selling stockholder which is a Holder of Registrable Securities and which is an investment fund, partnership, limited liability company or corporation, the partners, members, retired
partners, retired members, stockholders and Affiliates of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing persons shall be
deemed to be a single “selling Holder”, and any pro-rata reduction with respect to such “selling Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals
included in such “selling Holder,” as defined in this sentence. 
 2.8. Delay of Registration. No Holder shall have any
right to obtain or seek an injunction or restraining order or otherwise delay any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this
Section 2. 
 2.9. Indemnification. In the event any Registrable Securities are included in a registration statement under
this Section 2: 
 (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners,
members, officers, directors and stockholders of each Holder, legal counsel and accountants for each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Securities Act or the Exchange Act, against any Violation and the Company will pay to each such Holder, underwriter, controlling person or other aforementioned person, any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage, liability, or action as such expenses are incurred; provided, however, that the indemnity agreement contained in this subsection 2.9(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such
registration by any such Holder, underwriter, controlling person or other aforementioned person. 
  

 8 

 (b) To the extent, permitted by law, each selling Holder will severally and not jointly indemnify and
hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company,
any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the
foregoing persons may become subject, under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay
any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this subsection 2.9(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this subsection 2.9(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld; provided, further, that, in no event shall any indemnity under this subsection 2.9(b) exceed the net proceeds from the offering received by such Holder, except in the
case of fraud or willful misconduct by such Holder. 
 (c) Promptly after receipt by an indemnified party under this Section 2.9
of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.9, deliver to the indemnifying
party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the
defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right
to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action,
if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.9, but the omission so to deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.9. 
  

 9 

 (d) In order to provide for just and equitable contribution to joint liability under the Securities Act
in any case in which either (i) any Holder exercising rights under this Agreement, or any controlling person of any such Holder, makes a claim for indemnification pursuant to this Section 2.9 but it is judicially determined (by the
entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this
Section 2.9 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling Holder or any such controlling person in circumstances for which indemnification is
provided under this Section 2.9, then, and in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such
proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity
to correct or prevent such statement or omission; provided however, that, in any such case, (I) no such Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered
and sold by such Holder pursuant to such registration statement, and (II) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation; provided further, that in no event shall a Holder’s liability pursuant to this Section 2.9(d), when combined with the amounts paid or payable by such holder
pursuant to Section 2.9(b), exceed the proceeds from the offering (net of any underwriting discounts or commissions) received by such Holder, except in the case of willful fraud by such Holder. 
 (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 
 (f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Company and Holders under this Section 2.9 shall
survive the completion of any offering of Registrable Securities in a registration statement under this Section 2, and otherwise and shall survive the termination of this Agreement. 
 2.10. Reports Under Exchange Act. With a view to making available to the Holders the benefits of Sec Rule 144 promulgated under the Securities Act
and any other rule or regulation of the SEC that may at any time permits a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to: 
 (a) make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the
first registration statement filed by the Company for the offering of its securities to the general public so long as the Company is subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act; 
 (b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

  

 10 

 (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request
(i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144, the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies
as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and
(iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. 
 2.11. Form S-3 Registration. In case the Company shall receive from Holders of Registrable Securities then outstanding a written request or
requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company will: 
 (a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and 
 (b) as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate
the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining
in such request as are specified in a written request given within 15 days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification
or compliance, pursuant to this Section 2.11: (1) if Form S-3 is not then available for such offering by the Holders; (2) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in
such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters’ discounts or commissions) of less than One Million Dollars ($1,000,000); (3) if the
Company shall furnish to the Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be materially detrimental to the Company and its stockholders for such Form S-3 Registration to
be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this
Section 2.11; provided, however, that the Company shall not utilize this right more than once in any twelve month period, and, provided further that the Company shall not register any securities for the account of
itself or any other stockholder during such ninety day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under
SEC Rule 145, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only
Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered); (4) if the Company has, within the twelve (12) month period preceding the date of such request, already effected two
(2) registrations on Form S-3 for the Holders pursuant to this Section 2.11; or (5) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance; or (6) during the period ending one hundred eighty (180) days after the effective date of a registration statement subject to Section 2.2 hereof. 

(c) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to
be registered as soon as practicable after receipt of the request or requests of the Holders. All expenses incurred in connection with a registration requested pursuant to Section 2.11, including (without limitation) all registration,
filing, qualification, 

  

 11 

 
printer’s and accounting fees and the reasonable fees and disbursements of counsel for the selling Holder or Holders and counsel for the Company, but
excluding any underwriters’ discounts or commissions associated with Registrable Securities, shall be borne by the Company. Registrations effected pursuant to this Section 2.11 shall not be counted as demands for registration or
registrations effected pursuant to Sections 2.1. 
 (d) If the Initiating Holders intend to distribute the Registrable Securities
covered by their request by means of an underwriting, they shall so advise the Company as part of their request made pursuant to this Section 2.11 and the Company shall include such information in the written notice referred to in
Section 2.11(a). The provisions of Section 2.1(b) shall be applicable to such request (with the substitution of Section 2.11, for references to Section 2.1). 
 2.12. Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder (a) to
include such securities in any registration unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the
amount of the Registrable Securities of the Holders that are included or (b) to demand registration of any securities held by such holder or prospective holder. 
 2.13. “Market Stand-Off” Agreement. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final
prospectus relating to the Company’s IPO and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days which period may be extended upon the request of the managing
underwriter for an additional period of up to fifteen (15) days if the Company issues or proposes to issue an earnings or other public release within fifteen (15) days of the expiration of the 180-day lockup period) (i) lend, offer,
pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock
or any securities convertible into or exercisable or exchangeable for Common Stock held immediately prior to the effectiveness of the Registration Statement for such offering, or (ii) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash
or otherwise. The foregoing provisions of this Section 2.13 shall apply only to the Company’s IPO, shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall only be applicable to
the Holders if all officers, directors and greater than one percent (1%) stockholders of the Company enter into similar agreements. The underwriters in connection with the Company’s IPO are intended third-party beneficiaries of this
Section 2.13 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in
the Company’s IPO that are consistent with this Section 2.13 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the
underwriters shall apply to all Holders subject to such agreements pro rata based on the number of shares subject to such agreements, except that, notwithstanding the foregoing, the Company and the underwriters may, in their sole discretion, waive
or terminate these restrictions with respect to up to 100,000 shares of the Company’s Common Stock. 
  

 12 

 In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with
respect to the Registrable Securities of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. 
 2.14. Termination of Registration Rights No Holder shall be entitled to exercise any right provided for in this Section 2, after five
(5) years following the consummation of a Qualified Public Offering. 
 (b) In addition, the right of any Holder to exercise any right
provided for in this Section 2, including the right to request registration or inclusion in a registration, shall terminate when all shares of Registrable Securities held by such Holder can be sold without restriction under SEC Rule
144(k). 
 3. Inspection Rights and Confidentiality. 
 3.1. Inspection. The Company shall permit an Investor or Stockholder, at such Investor’s or Stockholder’s expense, to visit and inspect the Company’s properties, to examine its books of account
and records and to discuss the Company’s affairs, finances and accounts with its officers, all at such reasonable times as may be reasonably requested by the Investor or Stockholder; provided, however, that the Company shall not
be obligated pursuant to this Section 3.1, to provide access to any information which it reasonably considers to be a trade secret or similar confidential information or would adversely affect the attorney-client privilege between the
Company and its counsel. The covenant set forth in this Section 3.1 shall terminate and be of no further force or effect (i) immediately prior to the consummation of an IPO, (ii) when the Company first becomes subject to the
periodic reporting requirements of Sections 12(g) or 15(d) of the Exchange Act; or (iii) upon a Sale of the Company, whichever event shall first occur. 
 3.2. Confidentiality. Each Investor agrees that such Investor will keep confidential and will not disclose, divulge or use for any purpose, other than to monitor its investment in the Company, any confidential
information obtained from the Company pursuant to the terms of this Agreement, unless such confidential information (i) is known or becomes known to the public in general (other than as a result of a breach of this Section 3.2 by
such Investor), (ii) is or has been independently developed or conceived by the Investor without use of the Company’s confidential information or (iii) is or has been made known or disclosed to the Investor by a third party without a
breach of any obligation of confidentiality such third party may have to the Company; provided, however, that an Investor may disclose confidential information (a) to its attorneys, accountants, consultants, and other
professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company, (b) to any prospective investor of any Registrable Securities from such Investor as long as such prospective investor
agrees to be bound by the provisions of this Section 3.2 or executes a similar confidentiality agreement, (c) to any Affiliate, partner, member, stockholder, prospective investor or acquirer or wholly owned subsidiary of such
Investor or such other person with whom Investor is considering entering into a strategic relationship as long as such person agrees to be bound by the provisions of this Section 3.2 or executes a similar confidentiality agreement or
(d) as may otherwise be required by law (including without limitation disclosure of financial and other information required to be made in regulatory filings by Arrowhead), provided that the Investor takes reasonable steps to minimize the
extent of any such required disclosure. The Company acknowledges that the Investors may be in the business of venture capital investing and therefore review the business plans and related proprietary information of many enterprises, including
enterprises which may have products or services which compete directly or indirectly with those of the Company. Nothing in this Agreement shall preclude or in any way restrict the Investors from investing or participating in any particular
enterprise whether or not such enterprise has products or services which compete with those of the Company.

 4. Right of First Offer; First Refusal Right on Future Rounds: Directed Shares Right of First Offer. Subject to
the terms and conditions specified in this Section 4.1, and applicable securities laws, in the event the Company proposes to offer or sell any New Securities, the Company shall first make an offering of such New Securities to each
Investor and Stockholder (for purposes of this Section 4.1 only, each a “Major Investor,” and collectively, “Major Investors”) in accordance with the following provisions of this Section 4.1.
A Major Investor shall be entitled to apportion the right of first offer hereby granted it among itself and its partners, members and Affiliates in such proportions as it deems appropriate. 
 (a) The Company shall deliver a notice, in accordance with the provisions of Section 6.6 hereof (the “Offer Notice”), to
each of the Major Investors stating (i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New
Securities. 
 (b) By written notification received by the Company, within twenty (20) calendar days after mailing of the Offer Notice,
each of the Major Investors may elect to purchase or obtain, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the number of shares of Common Stock issued and held
(and any other securities convertible into, or otherwise exercisable or exchangeable for, shares of Common Stock) by such Major Investor bears to the total number of shares of Common Stock of the Company then outstanding (assuming full conversion
and exercise of all convertible or exercisable securities). The Company shall promptly, in writing, inform each Major Investor that elects to purchase all the shares available to it (each, a “Fully-Exercising Investor”) of
any other Major Investor’s failure to do likewise. During the ten (10) day period commencing after receipt of such information, each Fully-Exercising Investor shall be entitled to obtain that portion of the New Securities for which Major
Investors were entitled to subscribe but which were not subscribed for by the Major Investors which is equal to the proportion that the number of shares of Common Stock issued and held by such Fully-Exercising Investor bears to the total number of
shares of Common Stock issued and held by all Fully-Exercising Investors who wish to purchase such unsubscribed shares. 
 (c) If all New
Securities referred to in the Offer Notice are not elected to be purchased or obtained as provided in Section 4.1(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in
Section 4.1(b) hereof, offer the remaining unsubscribed portion of such New Securities (collectively, the “Refused Securities”) to any person or persons at a price not less than, and upon terms no more favorable to the
offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof,
the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Major Investors in accordance with this Section 4.1. 
 (d) The right of first offer in this Section 4.1 shall not be applicable to: (i) shares of Common Stock issued or deemed issued to
employees or directors of, or consultants to, the Company or any of its subsidiaries pursuant to a plan, agreement, or arrangement approved by the Board; (ii) shares of Series C Preferred Stock issued in a transaction or series of transactions
in a bona fide private financing transaction of the Company; (iii) shares of Common Stock issued in an IPO; (iii) the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities outstanding on the
date hereof; (iv) securities issued in connection with any stock split or stock dividend of the Company; (v) the issuance of securities in connection with a bona fide business acquisition of or by the Company, whether by merger,
consolidation, sale of assets, sale or exchange of stock or otherwise unanimously approved by the Board; (vi) the issuance of stock, warrants or other securities or rights to persons or entities with which the Company has business relationships
provided such issuances are for other than primarily capital raising purposes and provided that at the time of any such issuance, the aggregate of such issuance 

  

 14 

 
and similar issuances in the preceding twelve month period do not exceed one percent (1%) of the then outstanding Common Stock of the Company (assuming
full conversion and exercise of all convertible and exercisable securities); or (vii) the issuance of up to an aggregate of 250,000 shares of Common Stock, or the grant of options or warrants therefor, in connection with any present or future
borrowing, line of credit, leasing or similar financing arrangement approved by the Board, including at least one Investor-Designated Director and by a majority of the members of the Board who are not employees of the Company or any subsidiary.

 (e) In lieu of complying with the provisions of this Section 4.1, the Company may elect to give notice to the Major Investors
within thirty (30) days after the issuance of New Securities. Such notice shall describe the type, price and terms of the New Securities: Each Major Investor shall have twenty (20) days from the date of receipt of such notice to elect to
purchase up to the number of New Securities that would, if purchased by such Major Investor, maintain such Major Investor’s percentage ownership position, calculated as set forth in Section 4.1(b) prior to giving effect to the
issuance of such New Securities. The closing of such sale shall occur within sixty (60) days of the date of notice to the Major Investors. 
 4.2. Directed IPO Shares. In the event of an IPO, the Company will use its reasonable best efforts to cause the managing underwriter(s) of such IPO to designate a number of shares equal to ten percent (10%) of the Company’s
shares of Common Stock to be offered in such IPO for sale under a “directed shares program” and shall instruct such underwriter(s) to allocate no less than fifty percent (50%) of such directed shares program to be sold to persons or
entities designated by the Investor, pro rata on the basis of the number of shares held by each such holder. The shares designated by the underwriter(s) for sale under a directed shares program are referred to herein as “directed shares.”
The Investors acknowledge that, despite the Company’s use of its reasonable best efforts, the underwriter(s) may determine in their sole discretion that it is not advisable to designate all such shares as directed shares in the IPO, in which
case the number of designated shares may be reduced or no directed shares may be designated, as applicable. The Investors also acknowledge that notwithstanding the terms of this Agreement, the sale of any directed shares to any person or entity
pursuant to this Agreement will only be made in compliance with Rule 2110 of the National Association of Securities Dealers, Inc. Conduct Rules, IM-21 10-1 and federal, state and local laws, rules and regulations. 
 4.3. Termination. The provisions of Section 4.1 shall terminate (i) immediately prior to the consummation of a Qualified Public
Offering, (ii) when the Company first becomes subject to the periodic reporting requirements of Sections 12(g) or 15(d) of the Exchange Act; or (iii) upon a Sale of the Company, whichever event shall first occur. The provisions of
Section 4.2 shall terminate upon a Sale of the Company. 
 5. Additional Covenants Insurance; Director Indemnification. The Company shall
maintain its existing policy of Directors and Officers Errors and Omissions insurance. The Company shall provide indemnification to the former directors of Carbon Nanotechnologies, Inc., a Delaware corporation (“CNI”) as and to the same
extent that the Company provides indemnification to directors of the Company under the certificate of incorporation and bylaws of the Company as of April 20, 2007. 
 5.2. Employee Agreements. The Company will cause each person now or hereafter employed by it or any subsidiary (or engaged by the Company or any subsidiary as a consultant/independent contractor) with access to
confidential information and/or trade secrets to enter into a non-disclosure and proprietary rights assignment agreement substantially in the form approved by the Board. In addition, the Company shall not amend, modify, terminate, waive or otherwise
alter, in whole or in part, any of the above-referenced agreements or any restricted stock agreement between the Company and any employee without the consent of those members of the Board elected solely by the Investors pursuant to the Voting
Agreement. 
  

 15 

 5.3. Vesting of Option, Stock Grants. Unless approved by the Board, including any
Investor-Designated Director, all future employees and consultants of the Company, who shall purchase, or receive options to purchase, shares of the Company’s capital stock following the date hereof shall be required to execute stock purchase
or option agreements providing for (i) vesting of shares over a four (4) year period, with twenty-five percent (25%) of the shares subject to such option vesting one (1) year after the applicable vesting commencement date and the
balance of the shares subject to such option vesting in a series of thirty-six (36) successive equal monthly installments over the thirty-six (36)-month period measured from the first anniversary of the vesting commencement date, and
(ii) a 180-day lockup period in connection with the Company’s IPO. The Company shall retain a “right of first refusal” on employee transfers until the Company’s IPO and the right to repurchase unvested shares at cost.

 5.4. Meetings of the Board. Unless otherwise determined by the vote of a majority of the directors then in office, the Board shall
meet at least quarterly in accordance with an agreed upon schedule. 
 5.5. Successor Indemnification. In the event that the Company
or any of its successors or assigns (i) consolidates with or merges into any other entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially
all of its properties and assets to any person or entity, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Company assume the obligations of the Company with respect to
indemnification of members of the Board as in effect immediately prior to such transaction, whether in the Company’s bylaws, Certificate of Incorporation, or elsewhere, as the case may be. 
 5.6. Termination of Covenants. The covenants set forth in this Section 5, except for Section 5.5, shall terminate and be
of no further force or effect (i) immediately prior to the consummation of the sale of shares of Common Stock in the Company’s IPO, (ii) when the Company first becomes subject to the periodic reporting requirements of Sections 12(g)
or 15(d) of the Exchange Act; or (iii) upon a Sale of the Company, whichever event shall first occur. 
 6. Miscellaneous. 
 6.1. Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by
reason of this Agreement, except as expressly provided in this Agreement. 
 6.2. Transfers of Rights. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, permitted assigns, heirs, executors and administrators of the parties hereto. The registration rights under Section 2 hereof, the
information rights under Section 3 hereof, and the rights of first refusal under Section 4 hereof, may only be transferred to transferees or assignees acquiring the greater of (a) at least 300,000 shares of Series A Preferred Stock,
Series B Preferred Stock and/or Series C Preferred Stock (on an as-converted basis and subject to appropriate adjustment for stock splits, stock dividends, combinations, and other recapitalizations) or (b) all shares of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock (or Common Stock issued upon conversion thereof), then held by the transferor; provided that each transferee or assignee of rights under this Agreement shall continue to be subject to the
terms hereof, and, as a 

  

 16 

 
condition to the Company’s recognizing such transfer, each transferee or assignee shall agree in writing to be subject to each of the terms of this
Agreement by executing and delivering an Adoption Agreement substantially in the form attached hereto as Exhibit A. Upon the execution and delivery of an Adoption Agreement by any transferee, such transferee shall be deemed to be a party
hereto as if such transferee’s signature appeared on the signature pages of this Agreement. By execution of this Agreement or of any Adoption Agreement, each of the parties appoints the Company as its attorney in fact for the purpose of
executing any Adoption Agreement that may be required to be delivered under the terms of this Agreement. The Company shall not permit the transfer of the Registrable Securities subject to this Agreement on its books or issue a new certificate
representing any such Registrable Securities unless and until such transferee shall have complied with the terms of this Section 6.2. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the
parties or their respective executors, administrators, heirs, successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. Notwithstanding the
foregoing, the rights of first refusal contained in Section 4 may be transferred or assigned only to a Person that is an “accredited” investor as defined in Rule 501 of the Securities Act. 
 6.3. Additional Investors. Notwithstanding anything to the contrary contained herein, if the Company issues additional shares of the
Company’s Series C Preferred Stock after the date hereof pursuant to a Series C Agreement, the Company shall cause any purchaser of such shares of Series C Preferred Stock to execute a counterpart signature page hereto as an Investor, and such
party shall thereby be bound by, and subject to, all the terms and provisions of this Agreement applicable to an Investor. 
 6.4.
Governing Law. This Agreement shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, without regard to its principles of conflicts of laws.

 6.5. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument. This Agreement may also be executed and delivered by facsimile signature and in two or more counterparts, each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument. 
 6.6. Titles and Subtitles. The titles and subtitles used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting this Agreement. 
 6.7. Notices. All notices and other
communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent
during normal business hours of the recipient, and if not so confirmed, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one
(1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the respective parties at their address as set forth on the signature
page or Schedule A hereto, or to such email address, facsimile number or address as subsequently modified by written notice given in accordance with this Section 6.6. 
 6.8. Costs of Enforcement. If any party to this Agreement seeks to enforce its rights under this Agreement by legal proceedings, the
non-prevailing party shall pay all costs and expenses incurred by the prevailing party, including, without limitation, all reasonable attorneys’ fees. 
 6.9. Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and 

  

 17 

 
either retroactively or prospectively), only with the written consent of (i) the Company, (ii) the holders of at least a majority of the
Registrable Securities then outstanding and held by the Stockholders and (iii) the holders of at least a majority of the Registrable Securities then outstanding and held by the Investors. Any amendment or waiver effected in accordance with this
paragraph shall be binding upon each holder of any Registrable Securities then outstanding, each future holder of all such Registrable Securities, and the Company. Notwithstanding the foregoing, this Agreement may not be amended or terminated and
the observance of any term hereunder may not be waived with respect to any Investor without the written consent of such Investor, unless such amendment, termination or waiver applies to all Investors in the same fashion (it being agreed that a
waiver of the provisions of Section 4 with respect to a particular transaction shall be deemed to apply to all Investors in the same fashion if such waiver does so by its terms, notwithstanding the fact that certain Investors may
nonetheless, by agreement with the Company, purchase securities in such transaction). The Company shall give prompt written notice of any amendment or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such
amendment, termination or waiver. Any amendment, termination or waiver effected in accordance with this Section 6.8 shall be binding on all parties hereto, even if they do not execute such consent. No waivers of or exceptions to any
term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision. Any party may agree to waive or amend its own rights
hereunder with respect to the Company or another party without the necessity of obtaining the consent or agreement of any other party. 
 6.10. Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision. 
 6.11. Aggregation of Stock. All shares of Registrable Securities held or acquired by Affiliates shall be aggregated together for the purpose of
determining the availability of any rights under this Agreement. 
 6.12. Entire Agreement. This Agreement (including the Schedules
hereto) constitutes the full and entire understanding and agreement between the parties with respect to the subject matter hereof, and any other prior written or oral agreement, or contemporaneous written or oral agreement, relating to the subject
matter hereof existing between the parties are expressly canceled. 
 6.13. Delays or Omissions. No delay or omission to exercise any
right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such nonbreaching or non-defaulting party nor shall it be
construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or
default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or
conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not
alternative. 
 6.14. Prior Agreement Superseded. Pursuant to Section 6.8 of the Prior Agreement, the undersigned parties who are
parties to such Prior Agreement hereby amend and restate the Prior Agreement to read in its entirety as set forth in this Agreement, all with the intent and effect that the Prior Agreement shall hereby be terminated and entirely replaced and
superseded by this Agreement.

 EXHIBIT A 
 ADOPTION AGREEMENT 
 This Adoption Agreement (“Adoption Agreement”) is
executed by the undersigned (the “Transferee”) pursuant to the terms of that certain Amended and Restated Investors’ Rights Agreement dated as of October [__], 2007 (the “Agreement”), by and among the
Company, Stockholder and certain of its Investors. Capitalized terms used but not defined in this Adoption Agreement shall have the respective meanings ascribed to such terms in the Agreement. By the execution of this Adoption Agreement, the
Transferee agrees as follows:

 ARTICLE II. 
 PARTICIPATION 
 2.1 An Eligible Individual shall become a Participant in the Deferral Plan by
(1) electing to make deferrals in accordance with Section 3.1 and (2) filing with the Company such other forms as the Committee may reasonably require for participation hereunder. 
 2.2 An Eligible Individual who completes the requirements of the preceding subsection of this Article II shall commence participation in the Deferral Plan as of the
first day of the Deferral Plan Year with respect to which Bonus is elected to be deferred. 
 ARTICLE III. 
 CONTRIBUTIONS 
 3.1 Elections to Defer
Bonus. 
 (a) General Rule. Each Eligible Individual may defer up to 50% (in whole percentages) of such Eligible
Individual’s Bonus for a Deferral Plan Year by filing with the Administrator a Deferral Election Form for such Deferral Plan Year that conforms to the requirements of this Section 3.1. Because the Bonus is performance-based compensation
based on services performed over a period of at least twelve (12) months, within the meaning of Section 409A(a)(4)(B)(iii) and the Treasury Regulations thereunder, an election to defer up to 50% (in whole percentages) of such Eligible
Individual’s Bonus may be filed no later than six months before the end of the period over which such services are to be performed, under the terms and conditions specified by the Committee, in accordance with Section 409A(a)(4)(B)(iii) of
the Code and the Treasury Regulations thereunder. A Participant shall make a separate election to defer Bonus for each Deferral Plan Year. 
 (b) Base RSUs. In the event an Eligible Individual elects to defer up to 50% of his or her Bonus, the deferred amounts of such Bonus shall be granted to such Eligible Individual in the form of Restricted Stock
Units (“Base RSUs”); provided, that such Eligible Individual is an employee or service provider of the Company on the date of grant. The Base RSUs shall be granted under the Plan and shall be evidenced by a Restricted Stock Unit
Agreement specifying the number of shares of Company common stock covered thereby, in such form as the Committee shall establish (“RSU Agreement”), and the Eligible Individual must sign such RSU Agreement as a condition of receiving
the Base RSUs. The Base RSUs shall be fully vested upon the date of grant. The number of shares of Company common stock covered by the Base RSUs shall be (i) the deferred amounts of the Eligible Individual’s Bonus (i.e., up to 50% of
Bonus), divided by (ii) the Fair Market Value (as defined in the Plan) of a share of Company common stock on the date of grant. The Base RSUs shall be distributed in accordance with Article IV of the Deferral Plan. 
 (c) Premium RSUs. In the event an Eligible Individual elects to defer up to 50% of his or her Bonus, the Company shall grant
additional Restricted Stock Units (“Premium RSUs”) to such Eligible Individual; provided, that such Eligible Individual is an employee or service provider of the Company on the date of grant. The Premium RSUs shall be granted under
the Plan and shall be evidenced by an RSU Agreement, and the Eligible Individual must sign such RSU Agreement as a condition of receiving the Premium RSUs. The Premium RSUs will fully vest on or around the third anniversary of the date of grant,
subject to the Participant’s continuing service to the Company through the vesting date. The number of shares of Company common stock covered by the Premium RSUs shall be (i) the number of shares of Company common stock covered by the
Eligible Individual’s Base RSUs, divided by (ii) three (rounded down to the next whole number of shares). The Premium RSUs shall be distributed in accordance with Article IV of the Deferral Plan.

 (d) Duration of Deferral Election. 
 (1) A Participant shall not modify or suspend his election to defer Bonus later than six months before the end of the period over which
such services are to be performed. 
 (2) A Participant must file a new deferral election for each subsequent Deferral Plan
Year. In the event a Participant fails to file a timely deferral election for the next Deferral Plan Year, the Participant shall be deemed to have elected not to defer any Bonus for such Deferral Plan Year. 
 3.2 FICA and Other Taxes. For each Deferral Plan Year in which a Participant who is an employee makes a deferral under Section 3.1, the Company shall
withhold from that portion of the Participant’s Bonus, in a manner determined by the Company, the Participant’s share of FICA and other employment taxes on such amount. If necessary, the Committee may reduce the Participant’s
deferrals under Section 3.1 or make deductions from his or her deferred amounts in order to comply with this Section, to the extent permitted under Section 409A of the Code and the Treasury Regulations thereunder. 
 3.3 Compliance with Section 16 of the Exchange Act. Notwithstanding any other provision of the Deferral Plan or any rule, instruction, election form or other
form, the Deferral Plan and any such rule, instruction or form shall be subject to any additional conditions or limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3)
that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, such Deferral Plan provision, rule, instruction or form shall be deemed amended to the extent necessary to conform to such applicable
exemptive rule. 
 ARTICLE IV. 
 DISTRIBUTIONS 
 4.1 Scheduled Distribution of Base RSUs and Premium RSUs. 
 (a) Distribution of Base RSUs. Subject to Section 4.2 below, the shares of Company common stock subject to the Base RSUs shall
be distributed (i.e., settled) on a date determined by the Committee on or prior to the date of grant (the “distribution date”). The distribution date generally shall be on or around the third anniversary of the date of grant. In
the Committee’s sole discretion, the Base RSUs may be settled, in part or solely, in cash in lieu of shares of the Company common stock, equal to (i) the Fair Market Value of a share of Company common stock on the distribution date,
multiplied by (ii) the number of Base RSUs to be distributed, subject to any applicable tax withholding. 
 (b) Distribution of Premium RSUs. Subject to Section 4.2 below, the
shares of Company common stock subject to the Premium RSUs shall be distributed (i.e., settled) as soon as administratively practicable after vesting, but in no event later than the 15th day of the third month following the end of (i) the Company’s fiscal year in which the Premium RSUs vest or (ii) the calendar year in which the Premium RSUs vest,
whichever is later. In the Committee’s sole discretion, the Premium RSUs may be settled, in part or solely, in cash in lieu of shares of the Company common stock, equal to (i) the Fair Market Value of a share of Company common stock on the
distribute date, multiplied by (ii) the number of Premium RSUs to be distributed, subject to any applicable tax withholding.

 4.2 Unscheduled Distributions of Base RSUs and Premium RSUs. 
 (a) Distribution upon Termination of Employment. In the event the Participant has a “separation from service” within the
meaning of Treasury Regulation Section 1.409A-1(h), the shares of Company common stock subject to the Base RSUs shall be distributed (i.e., settled) on the date of such termination of employment. The unvested shares of Company common stock
subject to the Premium RSUs as of the time of such separation from service shall be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company and the Participant’s right to acquire any shares of Company
common stock under the Premium RSUs shall immediately terminate. Notwithstanding the foregoing, if the Participant is deemed at the time of his or her separation from service to be a “specified employee” for purposes of
Section 409A(a)(2)(B)(i) of the Code, then to the extent delayed distribution of the Base RSUs and Premium RSUs to which the Participant is entitled under the Deferral Plan is required in order to avoid a prohibited distribution under
Section 409A(a)(2)(B)(i) of the Code, such portion of the Participant’s benefits shall not be provided to the Participant prior to the earlier of (A) the expiration of the six-month period measured from the date of the
Participant’s “separation from service” with the Company (as such term is defined in the Treasury Regulations issued under Section 409A of the Code) or (B) the date of Participant’s death. The determination of whether
the Participant is a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code as of the time of his or her separation from service shall be made by the Company in accordance with the terms of Section 409A of the
Code and applicable guidance thereunder (including without limitation Treasury Regulation Section 1.409A-1(i) and any successor provision thereto). 
 (b) Distribution upon Change in Control. In the event of a Change in Control, the shares of Company common stock subject to the Base RSUs shall be distributed (i.e., settled) on the date of such Change in
Control. The Premium RSUs shall be assumed or an equivalent restricted stock unit substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. 
 In the event that the successor corporation refuses to assume or substitute for the Premium RSUs, the Participant shall fully vest in the
shares of Company common stock as to which such Premium RSUs would not otherwise be vested and such Premium RSUs shall be distributed (i.e., settled) on the date of such Change in Control. 
 For the purposes of this Section, a Premium RSU shall be considered assumed if, following the Change in Control, the Premium RSU confers
the right to purchase or receive, for each share subject to the Premium RSU immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of Company
common stock for each share held on the effective date of the transaction. 
 (c) Distribution upon Death. In the event
of the Participant’s death, the vested shares of Company common stock subject to the Base RSUs shall be distributed (i.e., settled) to the Participant’s estate as soon as administratively practicable after the date of death, and the
unvested shares of Company common stock subject to the Premium RSUs as of the time of such death shall be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company and the Participant’s right to acquire
any shares of Company common stock under the Premium RSUs shall immediately terminate.

 Each Participant shall pay to the Company or make provision satisfactory to the Committee for payment of any taxes required by law to be withheld in
respect of the distribution of shares of Company common stock subject to the Restricted Stock Units under the Deferral Plan, no later than the date of the event creating the tax liability. In the Committee’s discretion, such tax obligations may
be paid in whole or in part, in any event up to the minimum amount required to be withheld based on the statutory withholding rates for federal and state tax purposes that apply to supplemental taxable income, in shares of Company common stock,
including shares obtained in connection with the Restricted Stock Units, if any, valued at their Fair Market Value on the date of distribution (rounded up to the nearest whole share of Company common stock). The Company may, to the extent permitted
by law, deduct any such tax obligations from any payment of any kind otherwise due to the Participant. 
 6.2 Amendment, Modification, Suspension or
Termination. 
 (a) The Committee may amend, modify, suspend or terminate the Deferral Plan in whole or in part, except

Deferral Plan. 
 (b) Notwithstanding anything to the contrary in the Deferral Plan, if and to the extent the Company shall
determine that the terms of the Deferral Plan may result in the failure of the Deferral Plan, or amounts deferred by or for any Participant under the Deferral Plan, to comply with the requirements of Section 409A of the Code, or any applicable
regulations or guidance promulgated by the Secretary of the Treasury in connection therewith, the Company shall have the authority to take such action to amend, modify, cancel or terminate the Deferral Plan or distribute any or all of the amounts
deferred by or for a Participate, as it deems necessary or advisable, including without limitation: 
 (1) Any amendment or
modification of the Deferral Plan to conform the Deferral Plan to the requirements of Section 409A of the Code or any regulations or other guidance thereunder (including, without limitation, any amendment or modification of the terms of any
applicable to any Participant’s Accounts regarding the timing or form of payment). 
 (2) Any cancellation or termination
of any unvested Restricted Stock Units without any payment to the Participant. 
 (3) Any cancellation or termination of any
Restricted Stock Units, with immediate payment to the Participant of the amount otherwise payable to such Participant. 
 Any such amendment, modification,
cancellation, or termination of the Deferral Plan may adversely affect the rights of a Participant without the Participant’s consent.

 Neither the establishment of the Deferral Plan nor any modification thereof, nor the creating of any fund or account, nor the payment of any benefits shall be construed as giving to any Participant or other person any
legal or equitable right against the Company except as provided in the Deferral Plan. In no event shall the terms of employment of, or membership on the Board by, any Participant be modified or in any way be effected by the provisions of the
Deferral Plan. The Deferral Plan shall not give rise to any right on the part of any employee participant to continue in the employ of the Company, or any subsidiary or affiliate thereof.

of the Deferral Plan shall be declared unenforceable or invalid for any reason, such unenforceability or invalidity shall not affect the remaining provisions of the Deferral Plan but shall be fully severable, and the Deferral Plan shall be construed
