 WHEREAS, the undersigned Series A Investors, Series B Investors, Series C Investors, and Series D Investors desire to terminate the Prior Agreement and to accept the rights created pursuant hereto
in lieu of the rights granted to them under the Prior Agreement; 
 WHEREAS, in order to induce the Company to approve the
issuance of the Series E Stock and to induce certain of the Investors to invest funds in the Company pursuant to the Purchase Agreement, the Investors and the Company hereby agree that this Agreement shall govern the rights of the Investors to
cause the Company to register shares of Common Stock 

 
issued or issuable to them under the U.S. securities laws and certain other matters as set forth herein; and 
 WHEREAS, pursuant to Sections 5.7 and 5.8 of the Prior Agreement, the Prior Agreement may be amended by the Company and Investors
holding at least seventy-five percent (75%) of the then outstanding Registrable Securities (for the purposes of this clause only, as defined in the Prior Agreement) party thereto, and the undersigned parties to this Agreement include the
Company and the holders of a majority of such Registrable Securities. 
 NOW, THEREFORE, the parties hereto agree as follows:

 1.        Termination of Prior Rights. Each party hereto agrees and
acknowledges that the Prior Agreement is hereby terminated and this Agreement supersedes all prior agreements and understandings among the parties with respect to registration rights for the Registrable Securities (as defined herein) and all other
matters addressed herein. 
 2.        Restrictions on Transferability. Each
Investor hereby acknowledges and agrees that the Preferred Stock or Common Stock issued upon conversion of the Preferred Stock shall not be sold, assigned, transferred or pledged except upon conditions specified in this Agreement, which conditions
are intended, among other things, to ensure compliance with the provisions of the Securities Act of 1933, as amended (the “Securities Act”). Each Investor will cause any proposed purchaser, assignee, transferee or pledgee of
the Preferred Stock to agree to take and hold such securities subject to the provisions specified in this Agreement. 
 3.        Registration Rights. 
 3.1        Certain Definitions. As used in this Agreement: 
 (a)        The terms “register,” “registered,” and “registration” refer to a registration effected by preparing and filing a registration statement
in compliance with the Securities Act and the subsequent declaration or ordering of the effectiveness of such registration statement. 
 (b)        The term “Registrable Securities” means (i) the shares of Common Stock of the Company (the “Common Stock”) issuable or issued
upon conversion of the Preferred Stock, (ii) the shares of Common stock issuable or issued upon conversion of the Preferred Stock issued upon exercise, conversion or exchange of the Warrants, (iii) the shares of Common Stock issued to the
Founders; provided, however, that such shares of Common Stock shall not be deemed Registrable Securities for purposes of Sections 3.2, 3.6, 3.15, 4.1, 4.2, 4.3 and 5.7 and (iv) any other shares of Common Stock issued as (or issuable upon the
conversion or exercise of any warrant, right or other security which is issued as) a dividend or other distribution with respect to, upon conversion of, in exchange for or in replacement of the shares referenced in (i), (ii) and
(iii) above, excluding in all cases, however, any Registrable Securities sold by a person in a transaction in which such person’s rights under this Agreement are not assigned; provided, however, that such Common Stock shall only be treated
as Registrable Securities if and so long as they have not been (A) sold to or through a broker or dealer or underwriter in a public distribution or a public securities transaction, including sales made pursuant to Rule 144 promulgated under the
Securities Act or (B) sold in a transaction exempt 

  

 2 

 
from the registration and prospectus delivery requirements of the Securities Act under Section 4(1) thereof so that all transfer restrictions, and
restrictive legends with respect thereto, if any, are removed upon the consummation of such sale. 
 (c)        The number of shares of “Registrable Securities then outstanding” shall be the sum of the number of shares of Common Stock outstanding that are Registrable Securities plus
the number of shares of Common Stock issuable upon exercise or conversion of then exercisable or convertible securities that are Registrable Securities. 
 (d)        The term “Holder” means any (i) Investor or (ii) other person owning or having the right to acquire Registrable Securities who acquired
such Registrable Securities in a transaction or series of transactions not involving any registered public offering or who validly was assigned rights hereunder by the transferor. 
 (e)        The term “Form S-3” means such form under the Securities Act as in
effect on the date hereof or any registration form under the Securities Act subsequently adopted by the Securities and Exchange Commission (“SEC”) that permits inclusion or incorporation of substantial information by reference to
other documents filed by the Company with the SEC. 
 (f)        The term
“Warrants” means (i) the warrants to purchase Series D Stock and (ii) the warrants to purchase Series E Stock. 
 3.2        Request for Registration. 
 (a)        Subject to the conditions of this Section 3.2, if the Company shall receive at any time after the earlier of (i) August 15, 2008 or (ii) twelve (12) months after
the effective date of the Company’s first firm commitment underwritten public offering of its Common Stock (the “Initial Offering”), a written request from the Holders of thirty percent (30%) or more of the
Registrable Securities then outstanding (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities with an anticipated aggregate
offering price of at least $5,000,000, then the Company shall, within twenty (20) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 3.2, use best efforts to
effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request to be registered in a written request received by the Company within twenty (20) days of the mailing of the
Company’s notice pursuant to this Section 3.2(a). 
 (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 this Section 3.2 and the Company shall include
such information in the written notice referred to in Section 3.2(a). In such event the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such
underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall enter into an underwriting 

  

 3 

 
agreement in customary form with the underwriter or underwriters selected for such underwriting by a majority in interest of the Initiating Holders (which
underwriter or underwriters shall be reasonably acceptable to the Company). Notwithstanding any other provision of this Section 3.2, if the underwriter advises the Company that marketing factors require a limitation of the number of securities
underwritten (including Registrable Securities), then the Company shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be
allocated to the Holders of such Registrable Securities on a pro rata basis based on the number of Registrable Securities held by all such Holders (including the Initiating Holders). In no event shall any Registrable Securities be excluded from such
underwriting unless all other securities are first excluded. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration. 
 (c)        The Company shall not be required to effect a registration pursuant to this Section 3.2: 
 (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)        after the Company has effected two (2) registrations pursuant to this
Section 3.2, and such registrations have been declared or ordered effective; or 
 (iii)        during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred eighty
(180) days following the effective date of, a Company-initiated registration subject to Section 3.3 below, provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become
effective; or 
 (iv)        if the Initiating Holders propose to dispose of
Registrable Securities that may be registered on Form S-3 pursuant to Section 3.6 hereof; or 
 (v)        if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 3.2, a certificate signed by the Company’s President or Chairman of the Board
stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration statement to be effected at such time, in which event the Company shall
have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders, provided that such right to delay a request shall be exercised by the Company not more than once in any
twelve-month period. 
 3.3        Company Registration. 
 (a)        If (but without any obligation to do so) 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 relating either to 

  

 4 

 
the sale of securities to participants in a Company stock option, stock purchase or similar plan or a registration relating to a corporate reorganization or
other transaction under SEC Rule 145), 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, the Company shall, subject to the provisions of Section 3.8, cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered. Each Holder’s written request
shall state the number of Registrable Securities such Holder wishes to include in such registration statement. Holders that do not elect to participate in any registration and underwriting under this Section 3.3 shall nevertheless continue to
have the right to include any Registrable Securities in subsequent registrations and underwritings to which this Section 3.3 is applicable. 
 (b)        The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 3.3 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 3.7 hereof. 
 (c)        Except as otherwise provided herein, there shall be no limit on the number of times
the Holders may request registration of Registrable Securities under this Section 3.3; provided that payment of expenses for such registrations is subject to Section 3.7. 
 3.4        Obligations of the Company. Whenever required under this Section 3 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 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 up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the
Registration Statement has been completed. 
 (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 for the period set forth in paragraph (a) above. 
 (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 best efforts to cause the listing of the Registrable Securities for trading on the Nasdaq Stock Market or on another national or regional securities exchange on which the Common
Stock of the Company is then listed or traded. 
  

 5 

 (e)        Use its 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. 
 (f)        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. 
 (g)        Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required
to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. 
 (h)        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. 
 3.5        Furnish
Information. The Holder or Holders of Registrable Securities included in any registration 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 required to effect the registration of such Holder’s Registrable Securities. 
 3.6        Form S-3 Registration. In case the Company shall receive from the Holders of at least fifty percent (50%) of the 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 shall: 
 (a)        promptly give written notice of the proposed registration, and any related
qualification or compliance, to all other Holders; and 
 (b)        use best
efforts to effect, as soon as practicable, 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 Holders’ Registrable
Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holders joining in such request as are specified in a written request given within fifteen (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 3.6: 
  

	 	 (1)
	 if Form S-3 is not available for use by the Company with respect to such offering by the Holders; 

  

 6 

	 	 (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 $1,000,000; 

  

	 	 (3)
	 if the Company shall furnish to the Holders a certificate signed by the President or Chairman of the Board of the Company stating that in the good faith judgment
of the Board of Directors of the Company, it would be seriously 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 one hundred twenty (120) days after receipt of the request of the Holder or Holders under this Section 3.6; provided, however, that the Company shall not utilize this right more
than once in any twelve-month period; 

  

	 	 (4)
	 if the Company has, within the twelve-month period preceding the date of such request, already effected one registration on Form S-3 for the Holders pursuant to
this Section 3.6; 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; 

 (c)        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 this Section 3.6 and the Company shall include such information in the written notice referred to in Section 3.6(a). The provisions of Section 3.2(b) shall be applicable to such request (with the substitution of
Section 3.6 for references to Section 3.2). 
 (d)        Subject to the
foregoing, the Company shall file a registration statement on Form S-3 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.
Registrations effected pursuant to this Section 3.6 shall not be counted as requests for registration effected pursuant to Section 3.2. Except as otherwise provided herein, there shall be no limit on the number of times the Holders may
request registration of Registrable Securities under this Section 3.6. 
 3.7        Expenses. The Company shall bear the registration expenses (exclusive of underwriting discounts, commissions and, other than as set forth below, expenses of special 
  

 7 

 
counsel of a selling stockholder) of up to two demand registrations pursuant to Section 3.2, three “piggyback registrations” pursuant to
Section 3.3 and all Form S-3 registrations pursuant to Section 3.6, including the expenses of one special counsel to the selling stockholders not to exceed Twenty-Five Thousand Dollars ($25,000). Notwithstanding the foregoing, the Company
shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 3.2 or Section 3.6 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), provided, however,
that in the case of a registration requested under Section 3.2 which is subsequently withdrawn, the Company shall pay the expenses of such registration if in connection therewith, the Holders of a majority of the Registrable Securities agree to
forfeit their right to one (1) demand registration pursuant to Section 3.2 and, provided, further, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business or
prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be
required to pay any of such expenses and shall retain their rights pursuant to Sections 3.2 and 3.6. 
 3.8        Underwriting Requirements. In connection with any offering involving an underwriting of shares being issued by the Company, the Company shall not be required under Section 3.3
to include the Registrable Securities of any Holder that fails to execute the underwriting agreement entered into between the Company and the underwriter or underwriters selected by it. In addition, the Company shall be required to include in the
offering only that number of Registrable Securities that the underwriters determine in good faith will not jeopardize the success of the offering (the securities so included to 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 such selling Holders), but in no event shall (i) the amount of securities of the selling Holders included in the offering be
reduced below twenty five percent (25%) of the total amount of securities included in such offering, unless such offering is the Initial Offering, in which case the selling Holders may be completely excluded if the underwriters make the
determination described above and no other stockholder’s securities are included, (ii) any securities held by the Founder be included if any securities held by the Investors are excluded, and (iii) any securities (other than those of
the Company) be included in such underwriting which would reduce the number of shares included by the Holders without the consent of the majority-in-interest of the Holders of the outstanding Registrable Securities that desire to include securities
in the offering. 
 3.9        Delay of Registration. No Holder shall have any
right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 3. 
 3.10        Indemnification. In the event any Registrable Securities are included in a
registration statement under this Section 3: 
 (a)        To the extent
permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter (as defined in the Securities Act) for such Holder 

  

 8 

 
and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended
(the “1934 Act”), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under such laws, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a
“Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or
supplement thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the
Company of the Securities Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the Securities Act, the 1934 Act or any state securities law; and the Company will pay as incurred to each such Holder,
underwriter or controlling person, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in
this subsection 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 or controlling person and is subject to the condition that, insofar as it relates to any such untrue statement, alleged untrue statement, omission or alleged omission made
in a preliminary prospectus on file with the SEC at the time the registration statement becomes effective or the amended prospectus filed with the SEC pursuant to Rule 424(b) (the “Final Prospectus”), such indemnity agreement shall
not inure to the benefit of (i) any underwriter, if a copy of the Final Prospectus was not furnished to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act, and if the
Final Prospectus would have cured the defect giving rise to the loss, liability, claim or damage or (ii) any Holder, if there is no underwriter and if a copy of the Final Prospectus was furnished to such Holder and was not subsequently
furnished by the Holder to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act, if the Final Prospectus would have cured the defect giving rise to the loss, liability, claim
or damage. 
 (b)        To the extent permitted by law, each selling Holder will
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, 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 (severally and not jointly) to which any of the foregoing persons may become
subject, under the Securities Act, the 1934 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, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant to 

  

 9 

 
this subsection, in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 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 that in no event shall any indemnity under this subsection exceed the net proceeds from the offering received by such Holder. 
 (c)        Promptly after receipt by an indemnified party under this Section 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, 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 shall have the right to retain its own 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, 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. 
 (d)        If the indemnification provided for in this Section is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any
loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss,
liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other 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; provided, however, that no contribution by any Holder, when combined with any amounts paid by such Holder pursuant to Section 3.10(b),
shall exceed the net proceeds from the offering received by such Holder. 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 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. 
 (e)        The obligations of the
Company and Holders under this Section shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 3, and otherwise. 
  

 10 

 (f)        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. 
 3.11        Reports Under Securities Exchange Act of
1934. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Securities Act and any other Rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to
the public without registration, the Company agrees to: 
 (a)        make and keep
public information available, as those terms are understood and defined in SEC Rule 144 (or any successor rule promulgated under the Securities Act, “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; and 
 (b)        file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the 1934 Act; and 
 (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 Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by
the Company), the Securities Act and the 1934 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 in the possession of or reasonably obtainable by the Company as any
Holder may reasonably request in availing itself of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. 
 3.12        Assignment of Registration Rights. The rights to cause the Company to register
Registrable Securities pursuant to this Section 3 may be assigned by an Investor to a transferee or assignee who agrees in writing to be bound by the terms hereof; provided that the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and provided, further, that such assignment shall be effective only if
immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Securities Act. The foregoing limitation shall not apply, however, to transfers by an Investor to other stockholders
of the Company, stockholders or other equity holders of an Investor, other entities in which an Investor is a stockholder or equity holder, affiliates, family members, family trusts, partners, limited partners or retired partners or members of the
Investor (including spouses and ancestors, lineal descendants and siblings of such partners or spouses who acquire Registrable Securities by gift, will or intestate succession) if all such transferees or assignees agree in writing to be bound by the
terms hereof and to appoint a single representative as their attorney in fact for the purpose of receiving any notices and exercising their rights under this Agreement. 
  

 11 

 3.13        Market Stand-Off Agreement.
Each Holder of Registrable Securities and each Founder hereby agrees that for a period not to exceed 180 days following the effective date of a registration statement of the Company filed under the Securities Act, it shall not, to the extent
requested by the Company and such underwriter, sell or otherwise transfer or dispose of (other than to donees who agree to be similarly bound) any Common Stock (or other securities) of the Company held by it at any time during such period except
Common Stock included in such registration; provided, however, that: 
 (a)        such agreement shall be applicable only to the first such registration statement of the Company which covers Common Stock (or other securities) to be sold on its behalf to the public in an
underwritten offering; 
 (b)        all officers and directors and greater than or
equal to one percent (1%) stockholders of the Company enter into similar agreements; and 
 (c)        the Company shall not during same period sell, or otherwise transfer or dispose any Common Stock of the Company, except in connection with the grant to and/or exercise of stock options by
employees, consultants and directors of the Company. 
 To enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of the Investor (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. The underwriters in connection with the
Company’s initial underwritten public offering are intended third-party beneficiaries of this Section 3.13 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Any discretionary
waiver or termination of the restrictions of any or all of such market stand-off 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.

 3.14        Termination of Registration Rights. No Holder shall be entitled
to exercise any right provided for in this Section 3 (a) after five (5) years following the consummation of the Company’s Initial Offering or (b) as to any Holder, during such earlier time at which the Company’s shares
are publicly traded on a national securities exchange or the Nasdaq Stock Market (or substantially equivalent or successor securities market) and all Registrable Securities held by such Holder can be sold in compliance with Rule 144.

 3.15        Limitation 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 at least seventy-five percent (75%) of the outstanding Registrable Securities, enter into any agreement granting any holder or prospective
holder of any securities of the Company registration rights senior to or pari passu with those granted to the Holders hereunder. 
 4.        Covenants of the Company. 
 The Company hereby covenants to each of the
Investors as follows: 
 4.1        Delivery of Financial Statements

  

 12 

 (a)        Basic Financial Information and
Reporting. 
  

	 	 (1)
	 The Company will maintain true books and records of account in which full and correct entries will be made of all its business transactions pursuant to a system
of accounting established and administered in accordance with generally accepted accounting principles consistently applied, and will set aside on its books all such proper accruals and reserves as shall be required under generally accepted
accounting principles consistently applied. 

  

	 	 (2)
	 The Company will furnish each Holder as soon as practicable after the end of each fiscal year of the Company, and in any event within ninety (90) days
thereafter, a consolidated balance sheet of the Company, as at the end of such fiscal year, and a consolidated statement of income and a consolidated statement of cash flows of the Company, for such year, all prepared in accordance with generally
accepted accounting principles and setting forth in each case in comparative form the figures for the previous fiscal year, all in reasonable detail. Such financial statements shall be accompanied by a report and opinion thereon by independent
public accountants of national standing selected by the Company’s Board of Directors. 

 (b)        In addition, the Company shall deliver to each Investor who holds at least 250,000 shares of Preferred Stock (as adjusted for any stock dividends, combinations, splits, recapitalizations,
or the like with respect to such shares) in the Company (a “Major Investor”), unaudited quarterly consolidated statements of income and cash flows of the Company in the same reasonable detail as the financial statements delivered
pursuant to Section 4.1(a)(2) and the Company’s operating business plan for the fiscal year prior to the beginning of that fiscal year. 
 4.2        Inspection. The Company shall permit each Major Investor, at such Major Investor’s expense, reasonable access to allow such Major Investor 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 requested by the Major Investor; provided,
however, that the Company shall not be obligated pursuant to this Section 4.2 to provide access to any information that it reasonably considers to be a trade secret or similar confidential information. 
 4.3        Right of First Offer. (a) Subject to the terms and conditions specified in this
Section 4.3, the Company hereby grants to each Major Investor a right of first offer (the “Right of First Offer”) to purchase up to or all of its pro rata share of any Additional Shares of Common Stock (as defined below) that
the Company may, from time to time, propose to sell and issue. A Major Investor’s pro rata share, for purposes of this Right of First Offer, is the ratio of: the number of shares of Common Stock owned by such Major Investor immediately prior to
the 
  

 13 

 
issuance of the Additional Shares of Common Stock, assuming full conversion of any Preferred Stock and the exercise of any option or warrant held by such
Major Investor, to the total number of shares of the Company’s outstanding Common Stock, assuming full conversion of the Preferred Stock and exercise of all outstanding convertible securities, rights, options and warrants. For purposes of this
Section 4.3, “Major Investor” includes any general partners or affiliates of a Major Investor. A Major Investor shall be entitled to apportion the Right of First Offer hereby granted it among itself and its affiliates in such
proportions as it deems appropriate. 
 (b)        In the event the Company proposes
to undertake an issuance of Additional Shares of Common Stock, it shall give each Major Investor written notice (the “Issuance Notice”) of its intention, describing the type of Additional Shares of Common Stock, their price and the
general terms upon which the Company proposes to issue the same. Each Major Investor shall have ten (10) business days after the receipt of such notice to agree to purchase up to or all of such Major Investor’s pro rata share of such
Additional Shares of Common Stock for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of the Additional Shares of Common Stock to be purchased. The Company shall promptly,
in writing, inform each Major Investor that purchases all the shares available to it (each, a “Fully-Exercising Investor”) of any other Major Investor’s failure to do likewise. During the 10-day period commencing after receipt
of such information, each Fully-Exercising Investor shall be entitled to obtain up to that portion of the Additional Shares of Common Stock for which Major Investors were entitled to subscribe but which were not subscribed for by the Major Investors
that is equal to the proportion that the number of shares of Registrable Securities then held by such Fully-Exercising Investor bears to the total number of shares of Registrable Securities held by all Fully-Exercising Investors (assuming full
conversion and exercise of all convertible or exercisable securities then outstanding). 
 (c)        If all Additional Shares of Common Stock that Major Investors are entitled to obtain pursuant to Section 4.3(a) are not elected to be obtained as provided in Section 4.3(a) and
(b), the Company may, during the ninety (90) day period following the expiration of the period provided in Section 4.3(b), offer the remaining unsubscribed portion of such Additional Shares of Common Stock to any person or persons at a
price not less than that, and upon terms no more favorable to the offeree than those specified in the Issuance Notice. If the Company does not enter into an agreement for the sale of the Additional Shares of Common Stock within such period, or if
such agreement is not consummated within ninety (90) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Additional Shares of Common Stock shall not be offered unless first reoffered to the Major
Investors in accordance herewith. 
 (d)        For the purposes of this
Section 4.3, Additional Shares of Common Stock shall mean any shares of, or securities convertible into or exchangeable or exercisable for any shares of, capital stock of the Company; provided that Additional Shares of Common Stock shall not
include (1) Common Stock issued upon conversion of Series A Stock, Series B Stock, Series C Stock, Series D Stock or Series E Stock; (2) the Warrants or any securities issuable or issued upon exercise, conversion or exchange of the
Warrants; (3) securities issued to employees, consultants, officers or directors of the Company pursuant to any stock grant, stock option plan, stock purchase plan or other employee stock incentive program approved by the Company’s Board
of Directors; (4) securities issued in any Qualified Public Offering (as defined 

  

 14 

 
in the Company’s Certificate of Incorporation, as amended from time to time); (5) securities issued pursuant to the acquisition by merger, purchase
of assets, or other reorganization, of another corporation by the Company whereby the stockholders of the Company will own greater than 50% of the voting power of the surviving entity; (6) securities issued in connection with any equipment
lease financing transaction, equipment purchase transaction, real estate leases or bank financing transaction, provided that such issuance is primarily for other than equity financing purposes; (7) securities issued to corporate or strategic
partners pursuant to transactions approved by the Company’s Board of Directors, provided that such issuance is primarily for other than equity financing purposes; (8) shares of Common Stock or Preferred Stock issued in connection with any
stock split, stock dividend, or recapitalization of the Company; or (9) Series E Stock issued after the date hereof pursuant to the terms of the Purchase Agreement. 
 4.4        Reservation of Common Stock. The Company will at all times reserve and keep available, solely for issuance and delivery upon the
conversion of the Preferred Stock, all Common Stock issuable from time to time upon such conversion. 
 4.5        Common Stock Vesting. All shares of Common Stock (including options therefor) granted to new employees shall after the date hereof (i) vest with respect to 25% of such shares
following the first year of service to the Company, and with respect to an additional 1/48th of such shares after each additional month of service to the Company, such that the shares shall be fully vested after four (4) years of service to the
Company, (ii) be nontransferable prior to vesting as provided in the preceding subsection (i), (iii) be subject to a right of first refusal in favor of the Company until the Company’s Initial Offering, and (iv) be subject to
Section 3.13 hereof. Shares of Common Stock (or options therefor) granted to members of the Board of Directors or advisors to the Company may vest monthly, provided that the vesting terms for such shares shall be approved by the Board of
Directors. 
 4.6        Proprietary Information and Inventions Agreements.
The Company shall require all employees and consultants to execute and deliver a Proprietary Information and Inventions Agreement in substantially the form provided to the Investors. 
 4.7        Termination of Covenants. The covenants of the Company contained in
Sections 4.1, 4.2, 4.3, 4.4 and 4.5 shall expire and terminate as to each Investor immediately after the effectiveness of the Company’s Initial Offering. 
 5.        Miscellaneous. 
 5.1        Assignment. Subject to the provisions of Section 3.12 hereof, 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 hereto. 
 5.2        Governing Law.
This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to
principles of conflicts of law. 
  

 15 

 5.3        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. 
 5.4        Notices. Unless otherwise provided, any notice under this Agreement shall be given in writing and shall be deemed effectively delivered
(a) upon personal delivery to the party to be notified, (b) upon confirmation of receipt by fax or electronic mail by the party to be notified if sent during normal business hours of the recipient; if not, then on the next business day,
(c) one (1) business day after deposit with a reputable overnight courier, prepaid for overnight delivery and addressed as set forth in (d), or (d) five days after deposit with the United States Postal Service, postage prepaid,
registered or certified with return receipt requested and addressed to the party to be notified at the address indicated for such party on the exhibits hereto, or at such other address as such party may designate by 10 days advance written notice to
the other party given in the foregoing manner. 
 5.5        Ownership. Each
Founder represents and warrants that such Founder is the sole legal and beneficial owner of the shares of stock subject to this Agreement and that no other person has any interest (other than a community property interest) in such shares.

 5.6        Severability. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, portions of such provisions, or such provisions in their entirety, to the extent necessary, shall be severed from this Agreement, and the balance of this Agreement shall be enforceable in accordance
with its terms. 
 5.7        Amendment, Waiver and Additional Rights. Any
provision of this Agreement (other than Sections 4.1(b), 4.2 and 4.3) may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only with
the written consent of (i) the Company and (ii) the Holders holding at least seventy-five percent (75%) of the then outstanding Registrable Securities; provided, however, that in the event that such amendment or waiver adversely
affects the obligations or rights of the Founders in a different manner than the other Holders, such amendment or waiver shall also require the written consent of the holders of a majority in interest of the Founders. The provisions of Sections
4.1(b), 4.2 and 4.3 may be amended or waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of (i) the Company and (ii) the holders of at least seventy-five percent
(75%) of the then outstanding Registrable Securities then held by the Major Investors. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each holder of any Registrable Securities, each future holder of all
such Registrable Securities, and the Company. 
 Any amendment or waiver effected in accordance with this Section 5.7
shall be binding upon each Holder of Registrable Securities. 
 5.8        Effect
of Amendment or Waiver. Each Investor and each such Investor’s respective successors and assigns acknowledge that by the operation of, and subject to, Section 5.7 hereof, the holders of at least seventy-five percent (75%) of the
then outstanding 

  

 16 

 
Registrable Securities, acting in conjunction with the Company, will have the right and power to diminish or eliminate all rights pursuant to this Agreement.

 5.9        Rights of Holders. Each Holder of Registrable Securities shall
have the absolute right to exercise or refrain from exercising any right or rights that such Holder may have by reason of this Agreement, including, without limitation, the right to consent to the waiver or modification of any obligation under this
Agreement, and such holder shall not incur any liability to any other holder of any securities of the Company as a result of exercising or refraining from exercising any such right or rights. 
 5.10        Delays or Omissions. No delay or omission to exercise any right, power or
remedy accruing to any party to this Agreement, upon any breach or default of the other party, shall impair any such right, power or remedy of such non-breaching 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 made 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 holder, shall be cumulative and not alternative. 
 5.11        Expenses. If any action at law or in equity is necessary to enforce or
interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled. 
 5.12        Aggregation of Stock. All shares of Registrable Securities held or acquired by
affiliated entities (including affiliated venture capital funds) or persons shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. 
 5.13        Addition of Investors. Notwithstanding anything to the contrary contained
herein, if, following the date hereof, the Company shall issue additional shares of Series E Stock pursuant to the Purchase Agreement, any purchaser of such shares of Series E Stock (the “New Purchaser”) shall become a party to this
Agreement by executing and delivering an additional counterpart signature page to this Agreement, in each case without having to obtain the signature, consent or permission of the Holders hereunder. Upon execution and delivery of said counterpart
signature page, the New Purchaser shall be deemed an Investor hereunder.

 Exhibit 10.1 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement
(“Agreement”) is made as of the          day of                     ,
20        , by and between Fortinet, Inc., a Delaware corporation (the “Company”), and
                     (“Indemnitee”). 
 RECITALS 
 WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals and entities, such as Indemnitee, to serve the Company; 
 WHEREAS, in order to induce Indemnitee to
continue to provide services to the Company, the Company wishes to provide for the indemnification of, and advancement of expenses to, Indemnitee to the maximum extent permitted by law; 
 WHEREAS, the Certificate of Incorporation of the Company (the “Certificate”) authorizes the Company to provide
indemnification of (and advancement of expenses to) directors, officers, agents (and any other persons to which Delaware law permits the Company to provide indemnification), subject only to limits created by applicable Delaware law, and Indemnitee
may also be entitled to indemnification pursuant to the Company’s Bylaws (the “Bylaws”) and the General Corporation Law of the State of Delaware (the “DGCL”); 
 WHEREAS, the Certificate, the Bylaws 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 of the Company (the “Board”), officers and other persons with respect to indemnification; 
 WHEREAS, the Company and Indemnitee recognize the continued difficulty in obtaining liability insurance for the directors, officers,
employees, agents, fiduciaries, stockholders and controlling persons of the Company and any other Enterprise (as defined herein), the significant and continual increases in the cost of such insurance and the general trend of insurance companies to
reduce the scope of coverage of such insurance; 
 WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers, employees, agents, fiduciaries, stockholders and controlling persons of the Company and any other Enterprise to expensive litigation risks at the same time as the
availability and scope of coverage of liability insurance provide increasing challenges for the Company; 
 WHEREAS,
Indemnitee does not regard the protection currently provided by applicable law, the Company’s governing documents and available insurance as adequate under the present circumstances, and Indemnitee and certain other directors, officers,
employees, agents, fiduciaries, stockholders and controlling persons of the Company and any other Enterprise may not be willing to continue to serve in such capacities without additional protection; 

 WHEREAS, the Board has determined that the increased difficulty in attracting and
retaining highly qualified individuals and entities such as Indemnitee is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such individuals and entities 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 individuals and entities 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; and 
 WHEREAS, this Agreement is a supplement to and in furtherance of the indemnification provided
in the Certificate, Bylaws, and any resolutions adopted pursuant thereto, and this Agreement shall not be deemed a substitute therefor, nor shall this Agreement be deemed to limit, diminish, or abrogate any rights of Indemnitee thereunder.

 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. Definitions. 
 As used in this Agreement: 
 (a)            “Change of Control” means any transaction or series of related transactions in which the shareholders before the transaction
or series of related transactions own less than 50% of the voting power of the Company after such transaction or series of related transaction. 
 (b)            “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent, fiduciary,
stockholder or controlling person of the Company or of any other corporation, partnership or joint venture, trust, employee benefit plan or other Enterprise which such person or entity 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, partnership, limited liability company, 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, trustee, general partner, managing member, officer, employee, agent, fiduciary, stockholder or controlling person. 
 (e)            “Expenses” shall include all reasonable
attorneys’ fees, retainers, court costs, transcript costs, fees and costs 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
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, supersedes bond, or other appeal bond or its equivalent. Expenses,

  

 -2- 

 
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
partner (or, if applicable, member) of such 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 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)            “Proceeding” means any threatened, pending or completed action, suit, arbitration, mediation, 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 or
investigative nature, including without limitation any such proceeding pending as of the date of this Agreement, in which Indemnitee was, is or will be involved as a party or otherwise by reason of the fact that Indemnitee is or was a director of
the Company, by reason of any action taken by Indemnitee or of any action on Indemnitee’s part while acting as director of the Company, or by reason of the fact that Indemnitee is or was serving at the request of the Company as a director,
trustee, general partner, managing member, officer, employee, agent, fiduciary, stockholder or controlling person of the Company or any 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. 
 Section 2. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with the provisions of this Section 2 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 2, Indemnitee shall be indemnified against all Expenses, judgments, fines and amounts paid in settlement actually
and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee 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 Indemnitee’s conduct was unlawful. Indemnitee shall not enter into any settlement in connection with a Proceeding without
ten (10) days prior notice to the Company. 
 Section 3. Indemnity in Proceedings by or in the Right of the
Company. 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 by or in the right of the 

  

 -3- 

 
Company to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee shall be indemnified against all Expenses actually and reasonably
incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee 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 3 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court of competent jurisdiction to be liable to
the Company, unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) 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 for such expenses as the Delaware Court or such other court shall deem proper. 
 Section 4. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of
this Agreement, 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 Indemnitee 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 Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or
matter. 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 5. Indemnification For Expenses of a Witness. Notwithstanding any other provision of this
Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by
Indemnitee or on Indemnitee’s behalf in connection therewith. 
 Section 6. Additional Indemnification.

 (a)            Notwithstanding any limitation in Sections 2,
3, or 4, the Company shall indemnify Indemnitee to the fullest extent permitted by law if Indemnitee is a party to or is 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 6(a), the meaning of the phrase “to the fullest extent permitted by 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 or such provision thereof; and 
  

 -4- 

 (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. 
 (c)            Notwithstanding any other provision of this Agreement, the
Company shall be liable to indemnify Indemnitee against all Expenses actually and reasonably incurred by or on behalf of Indemnitee in taking any action to enforce any provision of this Agreement if Indemnitee is the prevailing party in such action,
including all Expenses incurred in bringing a claim, counterclaim, or cross-claim in any Proceeding to enforce this Agreement or any provision hereof. 
 Section 7. Exclusions. Notwithstanding any provision in this Agreement to the contrary, 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; 
 (b)            for 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 Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law; provided, however, that
notwithstanding any limitation on the Company’s obligation to provide indemnification set forth in this Section 7(b) or elsewhere, Indemnitee shall be entitled to receive advancement of Expenses hereunder with respect to any such Claim
unless and until a court having jurisdiction over the Claim shall have made a final determination (as to which all rights of appeal therefrom have been exhausted or lapsed) that Indemnitee has violated said statute; or 
 (c)            for which payment is prohibited by applicable law.

 Section 8. Advances of Expenses. The Company shall advance any and all 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, made without regard to Indemnitee’s ability to repay such Advances, and shall be made 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. Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement which shall constitute an undertaking providing that Indemnitee undertakes to repay the advance if and to the extent that it is
ultimately determined by a court of competent jurisdiction in a final judgment, not subject to appeal, that Indemnitee is not entitled to be indemnified by the Company. This Section 8 shall not apply to any claim made by Indemnitee for which
indemnity is excluded pursuant to Section 7. The right to advances under this paragraph shall in all events continue until final disposition of any Proceeding, including any appeal therein.

 Section 9. Procedure for Notification and Defense of Claim. 
 (a)            To obtain indemnification under this Agreement, Indemnitee
shall submit to the Company a written request therefor. 
 (b)            The Company will be entitled to participate in the Proceeding at its own expense. 
 Section 10. Procedure Upon Application for Indemnification. 
 (a)            Upon written request by Indemnitee for indemnification pursuant to Section 9(a), a determination, if required by applicable law, with respect to
Indemnitee’s entitlement thereto shall be made in the specific case by (i) by a majority of the Disinterested Directors, even though less than a quorum, or (ii) if there are no Disinterested Directors or if the Disinterested Directors
so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee 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. Notwithstanding the foregoing sentence regarding the determination being made by the Disinterested Directors, if the determination is being made after any Change of Control, such determination must be made by
Independent Counsel. Indemnitee shall cooperate with the person, persons, or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such counsel 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 Independent Counsel 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)            The Independent Counsel shall be selected by Indemnitee. In the event the determination of entitlement to indemnification is to be made by Independent Counsel
pursuant to Section 10(a) hereof, the Independent Counsel shall be selected by Indemnitee subject to the provisions of this Section 10(b). The Company may, within ten (10) days after written notice of such selection, deliver to
Indemnitee 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 1 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 9(a) hereof, and the final disposition of the Proceeding, including any appeal therein, no Independent Counsel shall have
been selected and not objected to, Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Company to the 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 

  

 -6- 

 
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 10(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(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). 
 Section 11. Presumptions and Effect of
Certain Proceedings. 
 (a)            In making a
determination with respect to entitlement to indemnification hereunder, the person, persons, or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request
for indemnification in accordance with Section 9(a) of this Agreement, and the Company shall have the burden of proof to overcome that presumption in connection with the making by such person, persons, or entity of any determination contrary to
that presumption. Neither the failure of the Company (including that of the Board) or of Independent 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 the Board) or by Independent Counsel that Indemnitee has not met such applicable standard of conduct, shall be a
defense to the action, admissible as evidence against Indemnitee, referred to in any Proceeding for any purpose, or create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (b)            If the person, persons, or entity empowered or selected under
Section 10 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 Indemnitee’s written request for indemnification
pursuant to Section 9(b) of this Agreement, the requisite determination of entitlement to indemnification shall 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 Independent Counsel 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. 
 (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 guilty, 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 Indemnitee 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 Indemnitee’s conduct was unlawful.

 (d)            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

  

 -7- 

 
of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or the Board or counsel selected by any committee of
the Board or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser, investment banker or other expert selected with reasonable care by the Company or the Board or any
committee of the Board. The provisions of this Section 11(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this
Agreement. 
 (e)            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 12. Remedies of Indemnitee. 
 (a)            In the event that (i) a determination is made pursuant to Section 10 of this Agreement that Indemnitee is not
entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8 of this Agreement, (iii) payment of indemnification is not made pursuant to Section 4, 5, or 6 or the last
sentence of Section 10(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, or (iv) payment of indemnification pursuant to Section 2, 3 or 6 of this Agreement is not made within
ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication by a court of Indemnitee’s entitlement to such indemnification or advancement of Expenses.
Alternatively, Indemnitee, at Indemnitee’s 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. 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 10(a) of this Agreement that Indemnitee is not entitled to indemnification, any
judicial proceeding or arbitration commenced pursuant to this Section 12 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 12 the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. In any judicial proceeding or
arbitration commenced pursuant to this Section 12, in the event that the person, persons, or entity empowered or selected under Section 10 of this Agreement to determine whether Indemnitee is entitled to indemnification has not made such a
determination within the time period provided for under Section 11(b) of this Agreement, the Company shall stipulate and may not contest that Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed
to the best interests of the Company, and, with respect to any criminal action or Proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful. 
 (c)            If a determination shall have been made pursuant to Section 10(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 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material
fact 

  

 -8- 

 
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 be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 12 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. 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 such Expenses to Indemnitee that are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement 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. 
 Section 13. 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 Certificate, the Company’s Bylaws, 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 Indemnitee’s Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be
afforded currently under the Certificate, Bylaws and this Agreement, or any Enterprises’ Certificate, Bylaws, or indemnification 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. 
 (b)            To the extent that the Company maintains an insurance policy
or policies providing liability insurance for directors, trustee, partners, managing members, officers, employees, agents, fiduciaries, stockholders or controlling persons of the Company or of any other Enterprise, 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 person 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 Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 
  

 -9- 

 (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 hereunder (or for which advancement is provided
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, trustee, partner, managing member, officer, employee, agent, or fiduciary of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses
from such other Enterprise. 
 Section 14. Duration of Agreement. This Agreement shall continue until and terminate
upon the later of (a) six (6) years after the date that Indemnitee shall have ceased to serve as a director of the Company or as a director, trustee, partner, management member, officer, employee, agent, fiduciary, stockholder or
controlling person of the Company or any other Enterprise; or (b) one (1) year after the final termination of any Proceeding, including any appeal, 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 12 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, as the case may be, Indemnitee’s heirs, executors, administrators, successors and assigns. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise)
to all, substantially all or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform if no such succession had taken place. 
 Section 15.
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 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. 
  

 -10- 

 Section 16. 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 the Company, the Bylaws 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 17. 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 18. Notice by Indemnitee. Each 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 Indemnitee under this Agreement or otherwise. 
 Section 19. 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

 -11- 

 
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 21. 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, without regard
to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 12(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 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) appoint, to the extent such party is not otherwise subject to service of process in the State
of Delaware, The Corporation Trust Company, Wilmington, Delaware as its agent in the State of Delaware as such party’s agent for acceptance of legal process in connection with any such action or proceeding against such party with the same legal
force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court, and (v) 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 22. 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 23. Miscellaneous. 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.
