 AMENDED AND RESTATED INVESTORS’ RIGHTS AGREEMENT 

THIS AMENDED AND RESTATED INVESTORS’ RIGHTS AGREEMENT (the “Agreement”) is made as of the
7th day of January, 2010, by and among Violin Memory,
Inc., a Delaware corporation (the “Company”), the investors listed on Schedule A hereto, each of which is herein referred to as an “Investor” and the holders of Common Stock listed on Schedule B hereto,
each of which is herein referred to as a “Common Holder”. 
 RECITALS 

WHEREAS, certain of the Investors (the “Existing Investors”) are parties to that certain Investors’ Rights
Agreement dated as of February 20, 2007 by and among the Company, the Common Holders and such Existing Investors (the “Prior Agreement”); 
 WHEREAS, the Prior Agreement may be amended, and any provision therein waived, with the consent of the Company, and the holders of at least sixty percent (60%) of the Registrable Securities
(as such term is defined in the Prior Agreement); 
 WHEREAS, the Existing Investors, as holders of at least sixty
percent (60%) of the Registrable Securities (as such term is defined in the Prior Agreement), 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; and 
 WHEREAS, certain Investors are parties to that certain Series A and Series 1 Preferred Stock Purchase
Agreement of even date herewith (the “Purchase Agreement”), which provides that, as a condition to the closing of the sale of the Series A Preferred Stock and Series 1 Preferred Stock thereunder, the Prior Agreement shall be amended and
restated in its entirety as set forth herein. 
 NOW, THEREFORE, in consideration of the mutual promises and covenants
set forth herein, the Existing Investors hereby agree that the Prior Agreement shall be superseded and replaced in its entirety by this Agreement, and the parties hereto further agree as follows: 

NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS: 
 1. Registration Rights. The Company covenants and agrees as follows: 
 1.1
Definitions. For purposes of this Section 1: 
 (a) The term “Act” means the Securities Act of 1933, as
amended. 
 (b) The term “Form S-3” means such form under the Act as in effect on the date hereof or any registration
form under the Act subsequently adopted by the SEC that permits inclusion or incorporation of substantial information by reference to other documents filed by the Company with the SEC. 

 (c) The term “Holder” means any person owning or having the right to acquire
Registrable Securities or any assignee thereof in accordance with Section 1.11 hereof; provided, however, that each Common Holder shall be deemed to be a Holder for purposes of Sections 1.3, 1.5, 1.6, 1.7,1.8, 1.9, 1.10 and 1.13 only.

 (d) The term “Initial Offering” means the Company’s first firm commitment underwritten public offering of its
Common Stock under the Act. 
 (e) The term “1934 Act” means the Securities Exchange Act of 1934, as amended.

 (f) The terms “register,” “registered,” and “registration” refer to a registration effected by
preparing and filing a registration statement or similar document in compliance with the Act, and the declaration or ordering of effectiveness of such registration statement or document. 

(g) The term “Registrable Securities” means (i) the Common Stock issuable or issued upon conversion of the Preferred
Stock, (ii) the shares of Common Stock issued to the Common Holders, solely for the purposes of Sections 1.3, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10 and 1.13 and (iii) any Common Stock of the Company issued as (or issuable upon the conversion or
exercise of any warrant, right or other security that is issued as) a dividend or other distribution with respect to, or in exchange for, or in replacement of, the shares referenced in (i) and (ii) above, excluding in all cases, however,
any Registrable Securities sold by a person in a transaction in which his rights under this Section 1 are not assigned. The number of shares of “Registrable Securities” outstanding shall be determined by the number of shares of Common
Stock outstanding that are, and the number of shares of Common Stock issuable pursuant to then exercisable or convertible securities that are, Registrable Securities. 
 (h) The term “Rule 144” shall mean Rule 144 under the Act. 
 (i) The
term “Rule 144(b)(l)(i)” shall mean subsection (b)(l)(i) of Rule 144 under the Act as it applies to persons who have held shares for more than one (1) year. 
 (j) The term “SEC” shall mean the Securities and Exchange Commission. 

1.2 Request for Registration. 
 (a) Subject to the conditions of this Section 1.2, if the Company shall receive at any time after the earlier of (i) six (6) months after the effective date of the Initial Offering and
(ii) three years after January 7, 2010 (which is the date of the first closing under the Purchase Agreement), a written request from the Holders of at least a majority of the Registrable Securities then outstanding (for purposes of this
Section 1.2, the “Initiating Holders”) that the Company file a registration statement under the Act covering the registration of Registrable Securities with an anticipated aggregate offering price of at least $10,000,000, 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 1.2, use all commercially

  
 2 

 
reasonable efforts to effect, as soon as practicable, the registration under the 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 1.2(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 1.2 and the Company shall
include such information in the written notice referred to in Section 1.2(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 agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company (which underwriter or underwriters
shall be reasonably acceptable to a majority in interest of the Initiating Holders). Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Company that marketing factors require a limitation on 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 pro rata 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) Notwithstanding the foregoing, the Company shall not be required to effect a registration pursuant to this Section 1.2:

 (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 Act; or 
 (ii) after the Company has effected two (2) registrations pursuant to this Section 1.2, 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 a registration statement for its Initial Offering and ending on a date one hundred eighty (180) days following the effective date of the Initial Offering, provided that the Company is actively employing in good faith all commercially
reasonable efforts to cause such registration statement to become effective and delivers such notice within thirty (30) days of receipt of such request for registration; or 

  
 3 

 (iv) if the Initiating Holders propose to dispose of Registrable Securities that may be
registered on Form S-3 pursuant to Section 1.4 hereof; or 
 (v) if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 1.2 a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board stating that in the good faith judgment of the Board of Directors of the Company (the “Board of
Directors”), 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
forty-five (45) days after receipt of the request of the Initiating Holders, provided that such right shall be exercised by the Company not more than twice in any twelve (12)-month period and provided further that the Company shall not register
any securities for the account of itself or any other stockholder during such forty-five (45) day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a
corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the
Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered). 

1.3 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 Act in connection with the public offering of such securities (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate
reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable
Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered), the Company shall, at such time, promptly give each Holder written notice of
such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 3.5, the Company shall, subject to the provisions of Section 1.3(c), use
all commercially reasonable efforts to cause to be registered under the Act all of the Registrable Securities that each such Holder requests to be registered. 
 (b) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1.3 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 1.7 hereof. 

(c) Underwriting Requirements. In connection with any offering involving an underwriting of shares of the Company’s capital
stock, the Company shall not be required under this Section 1.3 to include any of the Holders’ securities in such 

  
 4 

 
underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by the Company (or by other persons entitled to select the
underwriters) and enter into an underwriting agreement in customary form with such underwriters, and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If
the total amount of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, that the underwriters determine in their sole discretion will not
jeopardize the success of the offering. In no event shall any Registrable Securities be excluded from such offering unless all other stockholders’ securities have been first excluded. In the event that the underwriters determine that less than
all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be apportioned pro rata among the selling Holders based on the number of
Registrable Securities held by all selling Holders or in such other proportions as shall mutually be agreed to by all such selling Holders. Notwithstanding the foregoing, in no event shall (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 public offering of the Company’s securities, in which case the selling
Holders may be excluded if the underwriters make the determination described above and no other stockholder’s securities are included in such offering or (ii) any securities held by a Common Holder be included in such offering if any
Registrable Securities held by any Holder (and that such Holder has requested to be registered) are excluded from such offering. For purposes of the preceding sentence concerning apportionment, for any selling stockholder that is a Holder of
Registrable Securities and that is a venture capital fund, partnership or corporation, the affiliated venture capital funds, partners, members, retired members, retired partners and stockholders of such Holder, or the estates and family members of
any such partners, members, retired members and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling
Holder” shall be based upon the aggregate amount of Registrable Securities owned by all such related entities and individuals. 
 1.4 Form S-3 Registration. In case the Company shall receive from the Holders of at least fifteen percent (15%) of the Registrable Securities (for purposes of this Section 1.4, the
“Initiating Holders”) 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 all commercially reasonable 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 

  
 5 

 
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 1.4: 
 (i) if Form S-3 is not available for such offering by the
Holders; 
 (ii) 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; 

(iii) if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 1.4 a certificate signed
by the Company’s Chief Executive Officer or Chairman of the Board stating that in the good faith judgment of the Board of Directors, 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 forty-five (45) days after receipt of the request of the Initiating Holders, provided that such right shall be exercised
by the Company not more than twice in any twelve (12)-month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such forty-five (45) day period (other than a
registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include
substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon
conversion of debt securities that are also being registered); 
 (iv) if the Company has, within the twelve (12) month
period preceding the date of such request, already effected two registrations on Form S-3 for the Holders pursuant to this Section 1.4; or 
 (v) 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 1.4 and the Company shall include such information in the written notice referred to in Section 1.4(a). The provisions of
Section 1.2(b) shall be applicable to such request (with the substitution of Section 1.4 for references to Section 1.2). 
 (d) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of
the request or requests of the Initiating Holders. Registrations effected pursuant to this Section 1.4 shall not be counted as requests for registration effected pursuant to Sections 1.2. 

  
 6 

 1.5 Obligations of the Company. Whenever required under this Section 1 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 all commercially reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a
majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the Registration Statement has
been completed; 
 (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 Act with respect to the disposition of all securities covered by such registration statement; 

(c) furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them; 
 (d) use all commercially reasonable 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;

 (e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such offering; 
 (f) 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 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,
and amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit 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; 
 (g) cause all such Registrable Securities registered pursuant to
this Section 1 to be listed on a national exchange or trading system and on each securities exchange and trading system on which similar securities issued by the Company are then listed; and 

  
 7 

 (h) provide a transfer agent and registrar for all Registrable Securities registered
pursuant to this Agreement and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 
 Notwithstanding the provisions of this Section 1, the Company shall be entitled to postpone or suspend, for a reasonable period of time, the filing, effectiveness or use of, or trading under, any
registration statement if the Company shall determine that any such filing or the sale of any securities pursuant to such registration statement would in the good faith judgment of the Board of Directors: 

(i) materially impede, delay or interfere with any material pending or proposed financing, acquisition, corporate reorganization or
other similar transaction involving the Company for which the Board of Directors has authorized negotiations; 
 (ii)
materially adversely impair the consummation of any pending or proposed material offering or sale of any class of securities by the Company; or 
 (iii) require disclosure of material nonpublic information that, if disclosed at such time, would be materially harmful to the interests of the Company and its stockholders; provided,
however, that during any such period all executive officers and directors of the Company are also prohibited from selling securities of the Company (or any security of any of the Company’s subsidiaries or affiliates). 

In the event of the suspension of effectiveness of any registration statement pursuant to this Section 1.5, the applicable time
period during which such registration statement is to remain effective shall be extended by that number of days equal to the number of days the effectiveness of such registration statement was suspended. 

1.6 Information from Holder. It shall be a condition precedent to the obligations of the Company to take any action pursuant to
this Section 1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of
such securities as shall be reasonably required to effect the registration of such Holder’s Registrable Securities. 
 1.7
Expenses of Registration. All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Sections 1.2, 1.3 and 1.4, including (without limitation) all
registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel for the selling Holders shall be borne by the Company.
Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 1.2 or Section 1.4 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

  
 8 

 
withdrawn registration), unless, in the case of a registration requested under Section 1.2, the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand
registration pursuant to Section 1.2 and provided, however, 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 Section 1.2 and 1.4. 
 1.8 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 1. 

1.9 Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 1:

 (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members,
officers, directors and stockholders of each Holder, legal counsel and accountants for each Holder, any underwriter (as defined in the Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the
Act or the 1934 Act, against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Act, the 1934 Act, any state securities laws or any rule or regulation promulgated under the Act, 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 supplements thereto, (ii) the omission or alleged omission to state in such
registration statement 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 Act, the 1934 Act, any state securities laws or
any rule or regulation promulgated under the Act, the 1934 Act or any state securities laws, and the Company will reimburse each such Holder, underwriter, controlling person or other aforementioned person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 1.9(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such
registration by any such Holder, underwriter, controlling person or other aforementioned person; provided further, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any
Holder or underwriter or other aforementioned person, or any person controlling such Holder or underwriter, from whom the person asserting any such losses, claims, damages or liabilities purchased shares in the offering,

  
 9 

 
if a copy of the most current prospectus was not sent or given by or on behalf of such Holder or underwriter or other aforementioned person to such person, if required by law to have been so
delivered, at or prior to the written confirmation of the sale of the shares to such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability. 

(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 Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such registration
statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, the 1934 Act, any state
securities laws or any rule or regulation promulgated under the Act, the 1934 Act or any state securities laws, 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
reimburse any person intended to be indemnified pursuant to this Section 1.9(b) for any legal or other expenses reasonably incurred by such person in connection with investigating or defending any such loss, claim, damage, liability or action
as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 1.9(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder (which consent shall not be unreasonably withheld), and provided that in no event shall any indemnity under this Section 1.9(b) exceed the net proceeds from the offering received by such Holder. 

(c) Promptly after receipt by an indemnified party under this Section 1.9 of notice of the commencement of any action (including
any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.9, deliver to the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the
parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by
the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section 1.9 to the extent of such prejudice, but the omission to so 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 1.9. 

  
 10 

 (d) If the indemnification provided for in this Section 1.9 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 the
indemnified party on the other hand 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 1.9(b), shall exceed the net proceeds from the offering received by such Holder. The relative fault of the indemnifying party and the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the
indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public
offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 
 (f) The
obligations of the Company and Holders under this Section 1.9 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1 and otherwise. 

1.10 Reports Under the 1934 Act. With a view to making available to the Holders the benefits of Rule 144 and any other rule or
regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to: 

(a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the effective
date of the Initial Offering; 
 (b) file with the SEC in a timely manner all reports and other documents required of the
Company under the 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 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 as may be reasonably requested to avail any Holder of any rule or regulation
of the SEC that permits the selling of any such securities without registration or pursuant to such form. 

  
 11 

 1.11 Assignment of Registration Rights. The rights to cause the Company to register
Registrable Securities pursuant to this Section 1 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such securities that (i) is a subsidiary, parent, partner, limited partner, retired
partner or stockholder of a Holder, (ii) is a Holder’s family member or trust for the benefit of an individual Holder, or (iii) after such assignment or transfer, holds at least two percent (2%) of the Registrable Securities
(subject to appropriate adjustment for stock splits, stock dividends, combinations or the like), provided: (a) 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; (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including, without
limitation, the provisions of Section 1.13 below; and (c) 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 Act.

 1.12 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not,
without the prior written consent of the Holders of at least a majority of the Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or prospective holder
(a) to include any of such securities in any registration filed under Section 1.2, Section 1.3 or Section 1.4 hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any
such registration only to the extent that the inclusion of such securities will not reduce the amount of the Registrable Securities of the Holders that are included or (b) to demand registration of their securities. 

1.13 “Market Stand-Off” Agreement. 
 (a) Each Investor and Common Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating
to the Initial Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days) (or such longer period, not to exceed 34 days after the expiration of the 180-day
period, as the managing underwriter or the Company shall request in order to facilitate compliance with FINRA rules or any successor or similar rule or regulation), (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock (other than those included in such registration), or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock,
whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing provisions of this Section 1.13 shall apply only to the
Company’s initial offering of equity securities, shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall only be applicable to the Investors

  
 12 

 
and Common Holders if all officers, directors and greater than one percent (1%) stockholders of the Company enter into similar agreements. The underwriters in connection with the Initial
Offering are intended third-party beneficiaries of this Section 1.13 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Investor and Common Holder further agrees to execute
such agreements as may be reasonably requested by the underwriters in the Initial Offering that are consistent with this Section 1.13 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the
restrictions of any or all of such agreements by the Company or the underwriters shall apply to all Investors and Common Holders subject to such agreements pro rata based on the number of shares subject to such agreements. 

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities
of each Investor and Common Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. 
 (b) Each Investor and Common Holder agrees that a legend reading substantially as follows shall be placed on all certificates representing all Registrable Securities of each Investor and Common Holder
(and the shares or securities of every other person subject to the restriction contained in this Section 1.13): 
 THE
SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD AFTER THE EFFECTIVE DATE OF THE ISSUER’S REGISTRATION STATEMENT FILED UNDER THE ACT, AS AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER
OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD IS BINDING ON TRANSFEREES OF THESE SHARES. 
 1.14 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this Section 1 (i) after two (2) years following the Initial Offering,
(ii) as to any Holder, such earlier time at which such Holder (A) can sell all shares held by it in compliance with Rule 144(b)(l)(i) or (B) holds less than five percent (5%) of the Company’s outstanding Common Stock and all
Registrable Securities held by such Holder (together with any affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) can be sold in any three (3)-month period without registration in compliance with Rule 144 or
(iii) after the consummation of a Liquidation Event, as that term is defined in the Company’s Restated Certificate of Incorporation (the “Restated Certificate”). 

2. Covenants of the Company. 
 2.1 Delivery of Financial Statements. The Company shall, upon request, deliver to each Investor (or transferee of an Investor) that holds at least five percent (5%) of the then outstanding
shares of Preferred Stock (a “Major Investor”): 
 (a) as soon as practicable, but in any event within ninety
(90) days after the end of each fiscal year of the Company, an income statement for such fiscal year, a balance sheet of the Company and statement of stockholders’ equity as of the end of such year, and a statement of cash flows for such
year, such year-end financial reports to be in reasonable detail, prepared in accordance with generally accepted accounting principles (“GAAP”), and, for fiscal year 2010 and each fiscal year of the Company thereafter, audited and
certified by independent registered public accounting firm of nationally recognized standing selected by the Company; 

  
 13 

 (b) as soon as practicable, but in any event within sixty (60) days after the end of
each of the first three (3) quarters of each fiscal year of the Company, an unaudited income statement, statement of cash flows for such fiscal quarter and an unaudited balance sheet as of the end of such fiscal quarter, prepared in accordance
with generally accepted accounting principles consistently applied (except as noted therein), with the exception that no notes need be attached to such statements and year-end audit adjustments may not have been made; 

(c) within thirty (30) days of the end of each month, (i) an unaudited income statement and statement of cash flows and
balance sheet for and as of the end of such month, in reasonable detail that shows comparison to plan, prepared in accordance with generally accepted accounting principles consistently applied (except as noted therein), with the exception that no
notes need be attached to such statements and year-end audit adjustments may not have been made and (ii) upon request by a Major Investor, an updated report of the Company’s capitalization as of the end of such month, which report shall
include, without limitation, all outstanding options, warrants, rights or other agreements for the purchase or acquisition from the Company of any shares of its capital stock; 

(d) as soon as practicable, but in any event at least thirty (30) days prior to the end of each fiscal year, a budget and business
plan for the next fiscal year, prepared on a monthly basis, including balance sheets, income statements and statements of cash flows for such months and, as soon as prepared, any other budgets or revised budgets prepared by the Company; and

 (e) such other information relating to the financial condition, business or corporate affairs of the Company as the Major
Investor may from time to time request, provided, however, that the Company shall not be obligated under this Section 2.1 to provide such other information (i) to any Major Investor that is affiliated with a competitor of the Company, as
determined in good faith by the Board of Directors or (ii) the Board of Directors determines in good faith to be a trade secret or similar confidential information. Notwithstanding the above, if such information is required in order to permit a
Major Investor to prepare its own financial statements then the limitations provided for in this Section 2.1(e) shall be disregarded and be of no force or effect. 
 2.2 Inspection. The Company shall permit each Major Investor, at such Major Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account and records
and to discuss the Company’s affairs, finances and accounts with its officers, all at such reasonable times as may be requested by the Major Investor; provided, 

  
 14 

 
however, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to any information (i) to any Major Investor that is affiliated with a competitor of the
Company, as determined in good faith by the Board of Directors or (ii) the Board of Directors determines in good faith to be a trade secret or similar confidential information. Notwithstanding the above, if such information is required in order
to permit a Major Investor to prepare its own financial statements then the limitations provided for in this Section 2.2 shall be disregarded and be of no force or effect. 

2.3 Termination of Information and Inspection Covenants. The covenants set forth in Sections 2.1 and 2.2 shall terminate and be
of no further force or effect upon the earlier to occur of (i) the consummation of the Initial Offering, (ii) when the Company first becomes subject to the periodic reporting requirements of Sections 12(g) or 15(d) of the 1934 Act,
whichever event shall first occur or (iii) the consummation of a Liquidation Event (as defined in the Restated Certificate). 
 2.4 Right of First Offer. Subject to the terms and conditions specified in this Section 2.4, the Company hereby grants to each Major Investor a right of first offer with respect to future
sales by the Company of its Shares (as hereinafter defined). For purposes of this Section 2.4, the term “Major Investor” includes any partners, members, directly or indirectly wholly-owned subsidiaries, parent entities that own all of
the equity interests of such Major Investor and 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 partners, members, directly or indirectly wholly-owned
subsidiaries, parent entities that own all of the equity interests of such Major Investor and affiliates in such proportions as it deems appropriate. 
 Each time the Company proposes to offer any shares of, or securities convertible into or exchangeable or exercisable for any shares of, its capital stock (“Shares”), the Company shall first make
an offering of such Shares to each Major Investor in accordance with the following provisions: 
 (a) The Company shall deliver
a notice in accordance with Section 3.5 (“Notice”) to the Major Investors stating (i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered and (iii) the price and terms upon which
it proposes to offer such Shares. 
 (b) By written notification received by the Company within twenty (20) calendar days
after the giving of Notice, each Major Investor may elect to purchase, at the price and on the terms specified in the Notice, up to that portion of such Shares that equals the proportion that the number of shares of Common Stock that are Registrable
Securities issued and held by such Major Investor (assuming full conversion and exercise of all convertible and exercisable securities then outstanding) bears to the total number of shares of Common Stock of the Company then outstanding (assuming
full conversion and exercise of all convertible and exercisable securities then outstanding). The Company shall promptly, in writing, inform each Major Investor that elects to purchase all the shares available to it (a “Fully-Exercising
Investor”) of any other Major Investor’s failure to do likewise. During the ten (10) day period commencing after such information is given, each Fully-Exercising Investor may elect to purchase that portion of the Shares for which
Major Investors were entitled to subscribe, but which were not 

  
 15 

 
subscribed for by the Major Investors, that is equal to the proportion that the number of shares of Registrable Securities issued and held by such Fully-Exercising Investor bears to the total
number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by all Fully-Exercising Investors who wish to purchase some of the unsubscribed shares. 

(c) If all Shares that Major Investors are entitled to obtain pursuant to Section 2.4(b) are not elected to be obtained as provided
in Section 2.4(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in Section 2.4(b) hereof, offer the remaining unsubscribed portion of such Shares 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 Notice. If the Company does not enter into an agreement for the sale of the Shares within such period, or if such agreement is not consummated
within sixty (60) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Major Investors in accordance herewith. 

(d) The right of first offer in this Section 2.4 shall not be applicable to any issuance of securities that does not constitute an
issuance of Additional Stock pursuant to the terms of the Restated Certificate and is hereby waived with respect to the Preferred Stock issued pursuant to the Purchase Agreement. In addition to the foregoing, the right of first offer in this
Section 2.4 shall not be applicable with respect to any Major Investor in any subsequent offering of Shares if (i) at the time of such offering, the Major Investor is not an “accredited investor,” as that term is then defined in
Rule 501(a) of the Act and (ii) such offering of Shares is otherwise being offered only to accredited investors. 
 (e)
The rights provided in this Section 2.4 may not be assigned or transferred by any Major Investor; provided, however, that a Major Investor that is a venture capital fund may assign or transfer such rights to an affiliated venture capital fund,
and a Major Investor that is a corporation may assign or transfer such rights to any directly or indirectly wholly-owned subsidiary or parent entity that owns all of the equity interests of such Major Investor. 

2.5 Observer Rights. Unless otherwise approved by the Board of Directors, the Company shall invite Jon C.R. Bennett (so long as
he is an employee of the Company) to attend all meetings of its Board of Directors in a nonvoting observer capacity and, in this respect, shall give such party copies of all notices, minutes, consents and other materials that it provides to its
directors; provided, however, that such party shall agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information so provided; and, provided further, that the Company reserves the right to withhold any
information and to exclude such party from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or would result in
disclosure of trade secrets to any of such representatives, or if such party is affiliated with a competitor of the Company. 

2.6 Proprietary Information and Inventions Agreements. The Company shall require all employees and consultants with access to
confidential information to execute and deliver a Proprietary Information and Inventions Agreement (the “PIIA”) in 

  
 16 

 
substantially the form approved by the Board of Directors. Such PIIA shall provide, among other things: (i) except as expressly provided in any written employment or consulting agreement
between the employee or consultant, such individual is either an at-will employee or a consultant to the Company, as the case may be; (ii) such individual will maintain all Company proprietary information in confidence; (iii) such
individual will assign all inventions created by such individual as an employee or consultant during his employment or service to the Company; and (iv) such individual will not disclose any information related to the Company’s work. 

2.7 Stock Vesting. Unless approved by the Board of Directors, each grant of shares of Common Stock (or options therefore) shall
vest in equal monthly installments over a four-year period. All grants of shares of Common Stock (or options therefore) shall be approved by the Board of Directors. 
 2.8 Directors’ and Officers’ Insurance. The Company shall, as soon as practicable after the date hereof, obtain Directors’ and Officers’ Insurance with a carrier and in an
amount and terms satisfactory to the Board of Directors. In the event that the Company merges with or into another entity and is not the surviving entity following the merger, or transfers all of its assets, the Company shall use its best efforts to
ensure that successors to the Company assume the Company’ obligations with respect to the indemnification of the directors. 
 2.9 Board Committees. The Board of Directors will establish a compensation committee which shall consist of at least one director appointed by the holders of the Series A Preferred Stock and one
director appointed by the holders of the Series 1 Preferred Stock. The compensation committee shall review and determine the compensation of the Company’s executive officers. 

2.10 Directors. The Company shall promptly reimburse in full each director of the Company who is not an employee of the Company
for all of his reasonable out-of-pocket expenses incurred in attending each meeting of the Board of Directors, any committee thereof and other activities performed upon request of the Company. Each director of the Company that is not an employee or
affiliate of an Investor shall receive equity compensation and/or other incentives commensurate with such director’s duties to the Company. 
 2.11 Termination of Certain Covenants. The covenants set forth in Sections 2.4, 2.5, 2.6, 2.7, 2.8, 2.9 and 2.10 shall terminate and be of no further force or effect upon the consummation of
(i) a Qualified Public Offering (as defined in the Restated Certificate) or (ii) a Liquidation Event (as defined in the Restated Certificate). 
 2.12 Notification and Repurchase Obligations. 
 (a) The Company shall
notify each Major Investor in writing at least thirty (30) days prior to (i) the exercise of any Right of Repurchase (as such term is defined those certain Stock Purchase Agreements pursuant to which the Company has, prior to such
exercise, issued (or may in the future issue) shares of its capital stock under the Company’s 2005 Stock Plan (the “Plan”)), (ii) any other redemption or reacquisition by the Company of shares of its capital stock, (iii) the
closing of any financing that results in an adjustment to the Conversion Price (as defined in the Restated Certificate) of any series of Preferred Stock, (iv) the expiration 

  
 17 

 
of any outstanding options, warrants or other rights to acquire from the Company any shares of its capital stock that results in a reduction in the number of authorized shares of capital stock of
Company on a Fully Diluted Basis, (v) any reduction in the number of shares authorized for issuance under the Plan or any similar plan established in the future, and (vi) any event that would or could reasonably be expected to cause such
Major Investor’s equity interest in the Company to exceed 19.9% on a Fully Diluted Basis, in each case identifying such Major Investor’s equity interest in the Company, on a Fully Diluted Basis, subsequent to the occurrence of such event.
Notwithstanding the foregoing, the Company shall not be required to notify any Major Investor in accordance with the terms of this subsection unless (x) such Major Investor’s equity interest in the Company exceeds 18% on a Fully Diluted
Basis prior to the occurrence of an action contemplated herein or (y) the consummation of such action would cause such Major Investor’s equity interest in the Company to exceed 18% on a Fully Diluted Basis. 

(b) For the purposes of this Section 2.12, a “Fully Diluted Basis” shall mean an as-converted to Common Stock basis,
assuming conversion and exercise of all convertible and exercisable securities and including all shares available for issuance under the Plan or any similar plan established in the future. 

(c) Subject to applicable corporate law and the fiduciary duties of the Company’s Board of Directors, if at any time a Major
Investor holds an equity interest in the Company that exceeds 20% on a Fully Diluted Basis, such Major Investor may require the Company to repurchase that portion of such Major Investor’s Preferred Stock as is necessary to reduce such Major
Investor’s equity interest in the Company below 20% on a Fully Diluted Basis. Such repurchase shall occur within 3 days of the Company’s receipt of such Major Investor’s request, at a purchase price per share equal to the Original
Issue Price (as defined in the Restated Certificate) applicable to the series of Preferred Stock to be repurchased, plus any declared but unpaid dividends thereupon. 
 (d) The covenants set forth in this Sections 2.12 shall terminate and be of no further force or effect upon the consummation of (i) a Qualified Public Offering (as defined in the Restated
Certificate) or (ii) a Liquidation Event (as defined in the Restated Certificate). 
 3. Miscellaneous. 

3.1 Successors and Assigns. Except as otherwise provided herein, 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 (including transferees of any shares of Registrable Securities). Nothing in this Agreement, express or implied, is intended to confer upon any party other than the
parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

 3.5 Notices. All notices and other communications given or made pursuant hereto shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be
notified, (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; if not, then on the next business day, (iii) five (5) days after having been sent by registered or certified

3.6 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. 
 3.7 Entire Agreement: Amendments and Waivers. This Agreement (including the Exhibits hereto, if any) constitutes the full and entire understanding and agreement among the parties with regard to the
subjects hereof and thereof. Any term of this Agreement (other than Section 2.1, Section 2.2, Section 2.3 and Section 2.4) may be amended and the observance of any term of this Agreement may be waived only with the written
consent of the Company and the holders of at least a majority of the Registrable Securities; provided, however, that in the event that such amendment or waiver adversely affects the obligations or rights of the Common Holders 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 Common Holders. The provisions of Section 2.1, Section 2.2, Section 2.3, Section 2.4 and
Section 2.12 may be amended or waived only with the written consent of the Company and the holders of at least a majority of the Registrable Securities that are held by Major Investors (including, solely in the case of Section 2.12, each
holder of more than 9,000,000 shares of Preferred Stock, as adjusted for stock splits, stock dividends, combinations or the like)). 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. 
 3.8 Severability. If
one or more provisions of this Agreement are held to be unenforceable under applicable law, such provision(s) shall be excluded from this Agreement and the balance of the Agreement shall be interpreted as if such provision(s) were so excluded and
shall be enforceable in accordance with its terms.

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.

Company’s Series A Preferred Stock, Series I Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and any and all future series of preferred stock authorized under the Restated Certificate.

 VIOLIN MEMORY, INC. 

AMENDMENT TO AMENDED AND RESTATED INVESTORS
RIGHTS AGREEMENT 
 This AMENDMENT (the “Amendment”) to that certain Amended
and Restated Investors Rights Agreement dated as of January 7, 2010 (the “Rights Agreement”), is entered into as of November 13, 2012, by and among VIOLIN MEMORY, INC., a Delaware corporation (the “Company”)
and the undersigned Investors and Common Holders. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Rights Agreement. 
 W I T N E S S E T H: 
 WHEREAS, the Company
and each Investor are parties to the Rights Agreement; 
 WHEREAS, Section 3.7 of the
Rights Agreement provides that any term of the Rights Agreement may be amended or waived only with the written consent of the Company and the holders of a majority of the Registrable Securities then outstanding (the “Required
Investors”); 
 WHEREAS, the undersigned Investors constitute the Required
Investors; and 
 WHEREAS, the Company and the undersigned Investors desire to consent to
and waive the Company’s non-compliance with certain obligations of the Company under the Rights Agreement and to amend and supplement certain terms of the Rights Agreement as set forth in this Amendment: 

NOW, THEREFORE, in consideration of the mutual promises and covenants set forth
herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree to amend the Rights Agreement as follows: 

1. Section 1.1(c) of the Rights Agreement is hereby amended and replaced in its entirety by the following new Section 1.1(c):

 “(c) The term “Holder” means any person owning or having the right to acquire Registrable Securities or any
assignee thereof in accordance with Section 1.11 hereof; provided, however, that each Common Holder, other than Executive (as defined below), shall be deemed to be a Holder for purposes of Sections 1.3, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10 and 1.14
only; and provided, further, however, that Executive shall not be treated as a Common Holder for purposes of Section 1.3(c).” 
 2. Section 1.1(g) of the Rights Agreement is hereby amended and replaced in its entirety by the following new Section 1.1(g): 

“(g) The term “Registrable Securities” means (i) the Common Stock issuable or issued upon conversion of the Preferred
Stock, (ii) the shares of Common Stock issued to the Common Holders (other than Executive), solely for the purposes of Sections 1.3, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10 and 1.14, (iii) the shares of Common Stock issued to Don Basile
(“Executive”) for so long as such shares are held by Executive or any assignee thereof in accordance with Section 1.11 hereof and (iv) any Common Stock of the Company issued as (or issuable upon the conversion or 

  
 -1-

 
exercise of any warrant, right or other security that is issued as) a dividend or other distribution with respect to, or 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 his rights under this Section 1 are not assigned. The number of shares of “Registrable Securities”
outstanding shall be determined by the number of shares of Common Stock outstanding that are, and the number of shares of Common Stock issuable pursuant to then exercisable or convertible securities that are, Registrable Securities.”

 3. The following section is hereby added as a new Section 1.3(d) to the end of Section 1.3 to the Rights Agreement:

 “(d). Planned IPO. In the event of a Planned IPO (as defined herein), if the Underwriting Agreement entered into
by and among the Company and the Underwriter’s Representatives in connection with the Planned IPO provides that Registrable Securities and other outstanding shares of the Common Stock may be included in the Planned IPO (the “Secondary
Shares”), the Holders agree, notwithstanding anything to contrary in Section 1.3(c) and even if the Underwriter’s Representatives determine that less than all of the Registrable Securities requested to be registered by the Holders can
be included in the Planned IPO, that up to thirty-five percent (35%) of the aggregate number of Secondary Shares to be sold in the Planned IPO may be sold by certain employees and directors of the Company, including family members of such
individuals and trusts for the benefit of such individuals or such individuals’ family members, as determined in the sole discretion of the Board of Directors in such individual amounts as determined in the sole discretion of the Board of
Directors. After giving effect to this Section 1.3(d), any Secondary Shares to be sold in the Planned IPO by the Holders shall be included in the Planned IPO in accordance with terms set forth in Section 1.3(c) above. The term
“Planned IPO” means the first sale by the Company of Common Stock in a firm commitment underwritten public offering pursuant to an effective registration statement on Form S-1 (or any successor form) under the Securities Act that is
completed no later than October 31, 2013.” 
 4. Section 3.7 of the Rights Agreement is hereby amended and
replaced in its entirety by the following new Section 3.7: 
 “3.7 Entire Agreement; Amendments and Waivers.
This Agreement (including the Exhibits hereto, if any) constitutes the full and entire understanding and agreement among the parties with regard to the subjects hereof and thereof. Any term of this Agreement (other than Section 2.1,
Section 2.2, Section 2.3 and Section 2.4) may be amended and the observance of any term of this Agreement may be waived only with the written consent of the Company and the holders of at least a majority of the Registrable Securities;
provided, however, that in the event that such amendment or waiver adversely affects the obligations or rights of the Common Holders 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 Common Holders; provided, further, however, that in the event that such amendment or waiver adversely affects the obligations or rights of Executive in a different manner than the other Holders, such
amendment or waiver shall also require the written consent of Executive. The provisions of Section 2.1, Section 2.2, Section 2.3, Section 2.4 and Section 2.12 may be amended or waived only with the written consent of the
Company and the holders of at least a majority of the Registrable Securities that are held by Major Investors (including, solely in the case of Section 2.12, each 

  
 -2-

 
holder of more than 9,000,000 shares of Preferred Stock, as adjusted for stock splits, stock dividends, combinations or the like)). 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.” 
 5. Consent and Waiver. 
 Each Holder hereby consents to the Company’s
non-compliance with, and waives the observance by the Company of any and all rights of Holders under, Section 1.3 of the Rights Agreement to the extent that said Section 1.3 would require the Company to include in the Planned IPO more
shares than provided for in this Amendment or to provide Holders with 20 days to elect to participate in the Planned IPO. In addition, each Holder hereby consents to the Company’s non-compliance with, and waives the observance by the Company of
any and all rights of Holder under, the portion of Section 1.3, which provides for an allocation of shares among Holder in an underwritten offering that differs with the provisions contained in this Amendment, including but not limited to the
allocation of up to thirty-five percent (35%) of shares of Common Stock to be included in the Planned IPO by certain employees and directors of the Company. For the avoidance of doubt, no Holder, nor the Company, consents to any non-compliance
with, or waives the observance by the Company or the Holder, of the provisions of Section 1.3 that provide that the shares to be included by Holders may be cut-back in whole or in part if the Underwriter’s Representative determines in its
sole discretion that inclusion of such shares will jeopardize the success of the offering by the Company. 
 6. No Other
Changes. Except as expressly amended, modified or superseded hereby, the terms of the Rights Agreement shall remain in full force and effect. 
 7. Governing Law. This Amendment shall be governed by and construed under the laws of the State of Delaware, irrespective of conflicts of laws principles thereof. 

8. Entire Agreement. This Amendment and the documents referred to herein constitute the entire agreement among the parties with
respect to the subject matter and no party shall be liable or bound to any other party in any manner by any written or oral representations, warranties or covenants except as specifically set forth herein or therein. 

9. Telecopy Execution and Delivery. A facsimile, telecopy or other reproduction of this Amendment may be executed by one or more
parties hereto, and an executed copy of this Amendment may be delivered by one or more parties hereto by facsimile or similar electronic transmission device pursuant to which the signature of or on behalf of such party can be seen, and such
execution and delivery shall be considered valid, binding and effective for all purposes. At the request of any party hereto, all parties hereto agree to execute an original of this Amendment as well as any facsimile, telecopy or other reproduction
hereof.

RIGHTS AGREEMENTEX-4.4

 Exhibit 4.4 
 THIS WARRANT AND THE SHARES PURCHASABLE HEREUNDER HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER ANY STATE SECURITIES
LAWS. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR QUALIFICATION OR AN EXEMPTION THEREFROM UNDER SAID ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 

Dated: December 22, 2011 
 WARRANT TO PURCHASE 
 SERIES D PREFERRED STOCK OF 

VIOLIN MEMORY, INC. 
 This certifies that Toshiba America Electronic Components, Inc., or permitted assigns (collectively, the “Holder”), for value received, is entitled to purchase, at an exercise price of
$0.01 per share, from Violin Memory, Inc., a Delaware corporation (the “Company”), up to that number of fully paid and nonassessable Warrant Shares, equal to the quotient obtained in accordance with the following calculation:

  

											
		 	Warrant Shares	  	=	  		  	 Aggregate Unpaid Past Due Amounts
	 	
		 		  		  		  	the Stock Valuation Price	 	

 This Warrant shall be exercisable at any time from time to time up to and including the earlier of (i) 5:00 p.m.
(Pacific Time) on December 22, 2021, and (ii) immediately prior to the closing of any reorganization, consolidation or merger of the Company in a transaction pursuant to which the stockholders of the Company immediately prior to such
transaction do not hold a majority of the equity interests and voting power of the resulting or surviving entity immediately following such transaction (such earlier time being referred to herein as the “Expiration Date”) upon
delivery to the Company at its principal office of (i) the Form of Subscription attached hereto duly completed and executed, (ii) payment pursuant to Section 2 of the aggregate exercise price for the number of Warrant Shares for which
this Warrant is being exercised determined in accordance with the provisions hereof, and (iii) documentation supporting the applicable Aggregate Unpaid Past Due Amounts (as defined below) in respect of which this Warrant is being exercised. The
Stock Valuation Price and the number and constitution of the Warrant Shares purchasable hereunder are subject to adjustment as provided below and in Section 4 of this Warrant. 
 For purposes of this Warrant, (a) the term “Warrant Shares” means shares of Series D Preferred Stock, (b) the term “Stock Valuation Price” shall initially mean
$7.00 per share; provided that in the event of a Qualified Series D Preferred Stock Financing, the Stock Valuation Price shall be the price per share of the Company’s preferred stock sold by the Company in such Qualified Series D Preferred
Stock Financing, (c) the term “Qualified Series D Preferred Stock Financing” shall mean the next sale by the Company in a transaction or series of related transactions of shares of its preferred stock following the final
closing of the sale of the 

  
 1 

 
Company’s Series C Preferred Stock (whether such preferred stock is actually designated or denominated as Series D or otherwise; following a Qualified Series D Preferred Stock Financing, all
references herein to “Series D Preferred Stock” shall be deemed to be references to the preferred stock issued in a Qualified Series D Preferred Stock Financing) to investors in one or more transactions for aggregate cash proceeds to the
Company of no less than $2,000,000 for bona fide capital-raising purposes, and (d) the term “Aggregate Unpaid Past Due Amount” at any time shall mean the sum of (i) the aggregate undisputed unpaid amounts (including
interest accrued thereon) owed by the Company to Toshiba America Electronic Components, Inc. or its successor, that are then past due for payment pursuant to that certain Sales Agreement, dated effective as of June 27, 2011 by and between
Toshiba America Electronic Components, Inc. and the Company (the “Base Unpaid Past Due Amount”) and (ii) 0.5% of the Base Unpaid Past Due Amount; provided, however, that upon each exercise of this Warrant, the Aggregate Unpaid
Past Due Amount at the time of such exercise shall be reduced by the product obtained by multiplying (x) the number of Warrant Shares issued upon such exercise, by (y) the Stock Valuation Price. Upon written request of the Company at any
time, the Holder shall, as soon as reasonably practicable but in any event within 20 business days, deliver to Company a written statement of Holder’s computation of the Aggregate Unpaid Past Due Amount as of such date. 

The parties hereto acknowledge that this Warrant supersedes and replaces in all respects that certain Warrant to Purchase Series C
Preferred Stock of Violin Memory, Inc. issued to the Holder by the Company on February 2, 2011, which warrant is hereby rendered null, void and without further force or effect. 

1. Exercise; Issuance of Certificates; Acknowledgement. This Warrant is exercisable at the option of the holder of record hereof,
at any time or from time to time from the date hereof up to the Expiration Date for all or any part of the Warrant Shares (but not for a fraction of a share) which may be purchased hereunder. The Company agrees that the Warrant Shares purchased
under this Warrant shall be and are deemed to be issued to the Holder hereof as the record owner of such Warrant Shares as of the close of business on the date on which the executed Form of Subscription and supporting documentation delivered and
payment made for such Warrant Shares. Certificates for the Warrant Shares so purchased, together with any other securities or property to which the Holder hereof is entitled upon such exercise, shall be delivered to the Holder hereof by the Company
at the Company’s expense as soon as reasonably practicable but in any event within 20 business days after the rights represented by this Warrant have been so exercised. Each certificate so delivered shall be in such denominations of the Warrant
Shares as may be requested by the Holder hereof and shall be registered in the name of such Holder or its assignee. Notwithstanding anything to the contrary contained herein, unless the Holder otherwise notifies the Company, this Warrant shall be
deemed to be automatically exercised using the Net Issuance method pursuant to Section 2 hereof immediately prior to the time on the Expiration Date at which this Warrant ceases to be exercisable. 

2. Payment for Shares. The aggregate exercise price for Warrant Shares being purchased hereunder may be paid either (i) by
cash or wire transfer of immediately available funds, (ii) if the fair market value of one (1) Warrant Share on the date of exercise is greater than the exercise price, by surrender of a number of Warrant Shares which have a fair market
value equal to the aggregate exercise price of the Warrant Shares being purchased (“Net Issuance”) as determined herein, or (iii) any combination of the foregoing. If the Holder elects the Net

  
 2 

 
Issuance method of payment, the Company shall issue to Holder upon exercise a number of Warrant Shares determined in accordance with the following formula: 

 

					
	X=	  	 Y(A-B)
	  	
	  	A	  	

  

							
	where:	 	X	 	=	  	the number of Warrant Shares to be issued to the Holder;
				
		 	Y	 	=	  	the number of Warrant Shares with respect to which the Holder is exercising its purchase rights under this Warrant;
				
		 	A	 	=	  	the fair market value of one (1) Warrant Share on the date of exercise; and
				
		 	B	 	=	  	the exercise price.

 No fractional shares arising out of the above formula for determining the number of Warrant Shares to be
issued to the Holder shall be issued, and the Company shall in lieu thereof make payment to the Holder of cash in the amount of such fraction multiplied by the fair market value of one (1) Warrant Share on the date of exercise. For purposes of
this Warrant, the fair market value of one (1) Warrant Share shall mean (a) if the date of exercise is after the commencement of trading of the Common Stock on a securities exchange or over-the-counter but prior to the closing of the
initial public offering of the Company’s Common Stock pursuant to a registration statement under the Securities Act of 1933, as amended (the “IPO”), the price per share of such Common Stock to the public set forth on the final
prospectus relating to the IPO, multiplied (if Section 4.1 is not applicable) by the number of shares of Common Stock into which each Warrant Share is then convertible, (b) if the Common Stock is then traded on a securities exchange, the
average of the closing prices of such Common Stock on such exchange over the thirty (30) calendar day period (or portion thereof) ending three (3) days prior to the date of exercise, multiplied (if Section 4.1 is not applicable) by
the number of shares of Common Stock into which each Warrant Share is then convertible, (c) if the Common Stock is then regularly traded over-the-counter, the average of the closing sale prices or secondarily the closing bid of such Common
Stock over the thirty (30) calendar day period (or portion thereof) ending three (3) days prior to the date of exercise, multiplied (if Section 4.1 is not applicable) by the number of shares of Common Stock into which each Warrant
Share is then convertible, or (d) if there is no active public market for the Common Stock, the price per Warrant Share that the Company could obtain from a willing buyer for Warrant Shares sold by the Company, as such price shall be determined
in good faith by the Company’s board of directors. 
 3. Shares to be Fully Paid; Reservation of Shares. The Company
covenants and agrees that all Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant (together with all shares of Common Stock issuable upon conversion of such Warrant Shares, if applicable) will, upon
issuance, be duly authorized, validly issued, fully paid and nonassessable and free from all preemptive rights of any stockholder and free of all taxes, liens and charges with respect to the issue thereof. The Company further covenants and agrees
that during the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized and reserved, for the purpose of issue or transfer upon

  
 3 

 
exercise of the subscription rights evidenced by this Warrant, a sufficient number of Warrant Shares (which shall initially be that number of authorized but unissued Series D Preferred Stock
equal to the quotient obtained by dividing $45,000,000 by the Stock Valuation Price) (together with the number of shares of Common Stock issuable upon conversion of such Warrant Shares, if applicable), or other securities and property, when and as
required to provide for the exercise of the rights represented by this Warrant. 
 4. Adjustment of Warrant Shares and Stock
Valuation Price. The Stock Valuation Price and the number and constitution of Warrant Shares purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events described in this
Section 4. Upon each adjustment of the Stock Valuation Price or number and constitution of Warrant Shares purchasable upon the exercise of this Warrant (as adjusted pursuant to this Section 4), the Holder of this Warrant shall thereafter
be entitled to purchase, at the exercise price of $0.01 per share, the number of Warrant Shares obtained by dividing the Aggregate Unpaid Past Due Amounts by the Stock Valuation Price subsequent to such adjustment. 

4.1 Conversion of Preferred Stock. If, at a time when the Warrant Shares consist of shares of Preferred Stock, all of the
outstanding Preferred Stock of the Company are converted into shares of Common Stock, then this Warrant shall automatically become exercisable for that number of shares of Common Stock equal to the number of shares of Common Stock that would have
been received if this Warrant had been exercised in full immediately prior to such event and the shares of Preferred Stock received thereupon had been simultaneously converted into shares of Common Stock in connection with such event. Thereafter,
this Warrant shall become exercisable for such adjusted number of Warrant Shares consisting of shares of Common Stock, and the Stock Valuation Price shall not be adjusted. 
 4.2 Subdivisions, Combinations and Dividends. In case the Company shall at any time subdivide its outstanding Warrant Shares into a greater number of shares or pay a dividend in Warrant Shares in
respect of outstanding Warrant Shares, the Stock Valuation Price in effect immediately prior to such subdivision or at the record date of such dividend shall be proportionately reduced, and conversely, in case the outstanding Warrant Shares shall be
combined into a smaller number of shares, the Stock Valuation Price in effect immediately prior to such combination shall be proportionately increased. 
 4.3 Reclassification. If any reclassification of the capital stock of the Company shall be effected in such a way that holders of Warrant Shares shall be entitled to receive stock, securities, or
other assets or property (collectively, the “Reclassification Substitute”), then, as a condition of such reclassification, lawful and adequate provisions shall be made whereby the Holder hereof shall thereafter have the right to
purchase and receive (in lieu of the Warrant Shares immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such amount of Reclassification Substitute as may be issued or payable with respect to or in
exchange for a number of outstanding Warrant Shares equal to the number of Warrant Shares immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. Thereafter, this Warrant shall be exercisable for such
adjusted number of Warrant Shares consisting of Reclassification Substitute and the Stock Valuation Price shall not be adjusted. In any reclassification described above, appropriate provision shall

  
 4 

 
be made with respect to the rights and interests of the Holder of this Warrant to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Stock
Valuation Price and of the amount of Reclassification Substitute purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, as nearly as may be, in relation to any Reclassification Substitute thereafter deliverable
upon the exercise hereof. 
 4.4 Notice of Adjustment. Upon any adjustment of the Stock Valuation Price or the number and
constitution of Warrant Shares purchasable upon the exercise of this Warrant, the Company shall give written notice thereof, by first class mail postage prepaid, addressed to the registered Holder of this Warrant at the address of such Holder as
shown on the books of the Company. The notice shall be signed by the Company’s chief financial officer and shall state the Stock Valuation Price and number and constitution of Warrant Shares resulting from such adjustment, setting forth in
reasonable detail the method of calculation and the facts upon which such calculation is based. For the avoidance of doubt, the Company acknowledges that the Holder of this Warrant shall be entitled to the benefit of all adjustments in the number of
shares of Common Stock of the Company issuable upon conversion of Warrant Shares consisting of Preferred Stock which occur prior to the exercise of this Warrant, including without limitation, any increase in the number of shares of Common Stock
issuable upon conversion as a result of a dilutive issuance of capital stock. 
 4.5 Other Notices. If at any time:

 (1) the Company shall declare any cash dividend upon its Warrant Shares (or Common Stock issuable upon conversion thereof,
if applicable); 
 (2) there shall be any reorganization, consolidation or merger of the Company in a transaction pursuant to
which the stockholders of the Company immediately prior to such transaction do not hold a majority of the equity interests and voting power of the resulting or surviving entity immediately following such transaction; 

(3) there shall be any reclassification of the capital stock of the Company; 

(4) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Company; or 

(5) there shall be an IPO; 

then, in any one or more of said cases, the Company shall give, by first class mail, postage prepaid, addressed to the Holder of this Warrant at the
address of such Holder as shown on the books of the Company, (a) at least twenty (20) days prior written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend or for determining rights to vote
in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation,
winding-up or public offering, at least twenty (20) days prior written notice of the date when the same shall take place. Any notice given in accordance with the foregoing clause (a) shall also specify, in the case of any such dividend, the date on
which the holders of Warrant Shares (or Common Stock issuable 

  
 5 

 
upon conversion thereof, if applicable) shall be entitled thereto. Any notice given in accordance with the foregoing clause (b) shall also specify the date on which the holders of Warrant
Shares (or Common Stock issuable upon conversion thereof, if applicable) shall be entitled to exchange their Warrant Shares (or Common Stock issuable upon conversion thereof, if applicable) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, winding-up, conversion or public offering, as the case may be. 
 5. Miscellaneous. 
 5.1 Authorization of Series D Preferred Stock.
The Company hereby represents and warrants that on or prior to the date hereof, the Company has taken all required corporate actions to authorize and reserve for issuance upon exercise of this warrant at least 6,428,571 shares of Series D Preferred
Stock, each having a per share liquidation preference senior to all other shares of capital stock equal to or greater than $7.00. 
 5.2 Protective Provisions. From the date hereof until the closing of a Qualified Series D Preferred Stock Financing, other than in connection with the consummation of a Qualified Series D Preferred
Stock Financing that strictly complies with the terms of this Warrant, including but not limited to Section 5.3, the Company shall not, without first obtaining the written consent of the Holder: 

(a) alter or change, whether by merger, consolidation or otherwise, the rights, preferences or privileges of the shares of Series D
Preferred Stock; or 
 (b) increase or decrease the total number of authorized shares of Series D Preferred Stock. 

5.3 Series D Financing Documents. Upon the closing of any Qualified Series D Preferred Stock Financing, and whether or not the
Holder is issued shares of Series D Preferred Stock in connection with such Qualified Series D Preferred Stock Financing, the Holder shall, and shall be permitted to, enter into each agreement pursuant to which investors in the Qualified Series D
Preferred Stock Financing are granted contractual rights (and become subject to contractual obligations) in connection with the Qualified Series D Preferred Stock Financing, including, without limitation, an investors’ rights agreement or
registration rights agreement, a right of first refusal and co-sale agreement, and a voting agreement, thereby agreeing to be bound by all obligations and receive all rights thereunder as if the Holder were an investor in the Series D Preferred
Stock Financing with the effect that Holder shall become bound by the same obligations and entitled to the same rights thereunder with respect to Warrant Shares issued or issuable upon exercise of this Warrant as the other investors in such
Qualified Series D Preferred Stock Financing with respect to the shares of Series D Preferred Stock purchased by such other investors in such Qualified Series D Preferred Stock Financing. 

6. No Voting or Dividend Rights. Nothing contained in this Warrant shall be construed as conferring upon the Holder hereof the
right to vote or to consent to receive notice as a stockholder of the Company or any other matters or any rights whatsoever as a stockholder of the Company. No dividends or interest shall be payable or accrued in respect of this Warrant or

  
 6 

 
the interest represented hereby or the shares purchasable hereunder until, and only to the extent that, this Warrant shall have been exercised. 

7. Warrants Transferable. Subject to compliance with applicable federal and state securities laws, this Warrant and all rights
hereunder may be transferred, in whole or in part, without charge to the holder hereof (except for transfer taxes), upon surrender of this Warrant properly endorsed; provided, that the transferee shall be an entity that controls, is controlled by,
or is under common control with, the Holder (such entity, an “Affiliate”). For the avoidance of doubt, neither this Warrant nor any rights hereunder may be transferred to an entity that is not an Affiliate of the Holder. 

8. Lost Warrants. In the case of any loss, theft, destruction or mutilation of this Warrant, upon receipt of an indemnity
reasonably satisfactory to the Company, the Company, at its expense, will make and deliver a new Warrant, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant. 

9. Modification and Waiver. No term of this Warrant may be amended and the observance of any term of this Warrant may not be
waived (either generally or in a particular instance and either retroactively or prospectively) without the written consent of the Company and the Holder. 
 10. Notices. Except as may be otherwise provided herein, all notices, requests, waivers and other communications made pursuant to this Warrant shall be in writing and shall be conclusively deemed
to have been duly given (a) when hand delivered to the other party; (b) when sent by facsimile to the number set forth below if sent between 8:00 a.m. and 5:00 p.m. recipient’s local time on a business day, or on the next business day
if sent by facsimile to the number set forth below if sent other than between 8:00 a.m. and 5:00 p.m. recipient’s local time on a business day; (c) three business days after deposit in the U.S. mail with first class or certified mail

for purposes of this Section 10 by giving the other party written notice of the new address in the manner set forth above. 

11. Governing Law. This Warrant is to be construed in accordance with and governed by the laws of the State of California.

 AMENDMENT NO. 1 TO 

WARRANT TO PURCHASE SERIES D PREFERRED STOCK 
 OF VIOLIN MEMORY, INC. 
 THIS AMENDMENT NO. 1 TO WARRANT TO PURCHASE SERIES
D PREFERRED STOCK OF VIOLIN MEMORY, INC. (“Amendment”) is made as of the 30th day of November, 2012, by and among Violin Memory, Inc., a Delaware corporation (the “Company”), and Toshiba America Electronic
Components, Inc. or permitted assigns (the “Holder”). Terms not otherwise defined herein shall have the meaning ascribed to them in the Warrant (as defined below). 

RECITALS 
 A. The Company issued to the Holder a Warrant to Purchase Series D Preferred Stock dated December 22, 2011 (the “Warrant”), which Warrant superseded and replaced all other warrants
