 Exhibit 10.50 
 RIGHT OF LAST REFUSAL AGREEMENT 
 This Right of Last Refusal Agreement
(this “Agreement”) is made and entered into as of March 11, 2011 by and between Dell Products L.P., a Texas limited partnership (“Dell”), and Glasshouse Technologies, Inc., a Delaware corporation (the
“Company”). 
 RECITALS 
 WHEREAS, the Company and Dell desire to amend and restate that certain Subordinated Convertible Promissory Note (the “Original Note”) dated as of March 6, 2008, issued by the Company
to Dell; and 
 WHEREAS, the Company desires to induce Dell to enter into the Amended and Restated Subordinated Convertible
Promissory Note (the “Amended and Restated Note”) dated as of even date herewith by agreeing to the terms and conditions set forth herein. 
 NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

 1. Definitions. 
 (a) “Affiliate” means with respect to a specified Person, any Person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common
control with, the Person specified. 
 (b) “Asset Sale” means any sale, exchange, assignment, conveyance,
transfer, delivery, license, liquidation or other disposition of any of the Company’s or any of its Subsidiaries’ (defined below) properties or assets, including the Company’s or any of its Subsidiaries’ executory contracts and
associated resources, other than in the ordinary course of business consistent with the Company’s and its Subsidiaries’ historic past practice. 
 (c) “Beneficial Owner” has the meaning ascribed to it in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934. 

(d) “Extraordinary Transaction” means any of the following: 

(i) any merger, reorganization, share exchange, consolidation or other business combination involving the Company or any of its
Subsidiaries, other than (A) a merger or consolidation of the Company in which the holders of capital stock of the Company immediately prior to such merger or consolidation continue to hold a majority of the capital stock of the Company or the
surviving entity after giving effect to such merger or consolidation, and (B) any merger or similar transaction effected solely to change the domicile of the Company or any of its Subsidiaries; 

(ii) any acquisition by any Person or Group (defined below) (including any “person” within the meaning of Section 13(d) of
the Securities Exchange Act of 1934) as a result of which, such Person (or any Group of which such Person is a member) or Group becomes a Beneficial Owner of 50% or more of the issued and outstanding shares of capital stock of the Company or any of
its Subsidiaries in any single transaction or a series of related transactions; 

  
 1 

 (iii) any sale, liquidation or transfer of all or substantially all of the assets of the
Company; or 
 (iv) the redemption or repurchase of shares, the effect of which is that any Person or Group that did not
beneficially own a majority of the voting power of the outstanding shares of capital stock of the Company immediately prior to such redemption or repurchase owns at least a majority of such voting power of the outstanding shares of capital stock of
the Company after such redemption or repurchase; 
 provided, however, that a recapitalization of the Company in which the
Company’s stockholders of record (or their Affiliates) immediately prior to such recapitalization shall (as a result of the securities issued as part of the recapitalization) continue to hold all of the stock of the Company immediately
following such recapitalization (without regard to any change in relative ownership) shall not constitute an Extraordinary Transaction unless as a result of such recapitalization a strategic investor or its Affiliates (other than Dell and its
Affiliates) would be the holder of 50% or more of the voting power of the Company. 
 (e) “Group” means two or
more Persons acting as a partnership, limited partnership, syndicate or other group for the purpose of acquiring, holding or disposing of the applicable securities referred to herein.

 2 

 2. Restrictions on Sale Events. Upon the occurrence of any Event of Default
(as defined in the Amended and Restated Note) or any event of default of the Senior Indebtedness or the Junior Indebtedness (each as defined in that certain Amended and Restated Intercreditor Agreement dated as of March 29, 2010 by and among
the Company, Dell and the other parties thereto), and during the continuation of such Event of Default or event of default, as applicable, the Company shall not, directly or indirectly, and shall cause its Subsidiaries not to enter into or agree to
any Proposal or consummate a Sale Event unless the Company has complied with all of the terms of this Agreement. Any consummation of a Sale Event in violation of any term of this Agreement shall be void and ineffectual. Except as set forth herein,
the Company shall not and shall cause its Subsidiaries not to enter into any binding agreement or arrangement that (a) provides for the Company or any of its Subsidiaries to pay any fees and expenses, including any termination or break-up fees,
or any similar provisions with any Person with respect to a Sale Event or (b) imposes limitations or restrictions on the Company’s or any of its Subsidiaries’ ability to comply with all of the terms of this Agreement (“Letter of
Intent”). 
 3. Notice of Sale Event. 

(a) At least 10 business days prior to entering into or agreeing to any Proposal, the Company shall provide a written notice of such
Proposal (the “Company Notice”) to Dell. The Company Notice shall include (i) a true and correct copy of the Proposal, including all schedules, exhibits and ancillary documents related thereto, and (ii) the expected date of
consummation of such Sale Event. 
 (b) Immediately after delivering the Company Notice to Dell, the Company shall provide Dell
and its Representatives access to, and, if requested, copies of, the information and other diligence materials, including all non-public information of the Company or its Subsidiaries, that are or have been supplied to any third party or any third
party’s Representatives in connection with the Sale Event. 
 4. Right of Last Refusal. 

(a) Right of Last Refusal with Respect to an Extraordinary Transaction. Upon receipt of the Company Notice with respect to an
Extraordinary Transaction, Dell shall have the irrevocable and exclusive option, at its sole discretion, to become, or to have any of its Affiliates become, the purchaser with respect to the Extraordinary Transaction on substantially the same
financial terms as provided in the Proposal. If Dell elects to become, or to have any of its Affiliates become, the purchaser, Dell shall deliver a written notice (the “Dell Notice”) to the Company of such election within 10
business days of the receipt by Dell of the Company Notice (such 10-business day period, the “Extraordinary Transaction Review Period”). Upon receipt by the Company of the Dell Notice, the Company shall not enter into or agree to
the Proposal relating to the Extraordinary Transaction and shall enter into an agreement with Dell or any of its Affiliates (as designated by Dell) on substantially the same financial terms and containing substantially the same representations and
warranties, exclusivity (including any no-shop or other similar provisions) and indemnities in favor of Dell or any of its Affiliates (as designated by Dell) as provided in the Proposal. 

  
 3 

 (b) Right of Last Refusal with Respect to an Asset Sale. Upon receipt of the Company
Notice with respect to an Asset Sale, Dell shall have the irrevocable and exclusive option, at its sole discretion, to purchase, or to have any of its Affiliates purchase, any or all of the properties or assets involved in such Asset Sale on
substantially the same financial terms as provided in the Proposal, as adjusted for the specific properties or assets Dell elects to purchase, or to have any of its Affiliates purchase, as compared to all of the properties and assets subject to the
Proposal. If Dell elects to purchase, or to have any of its Affiliates purchase, any or all of the properties or assets involved in such Asset Sale, Dell shall deliver a written notice (the “Asset Sale Notice”) to the Company of
such election within 10 business days of the receipt of the Company Notice specifying the properties or assets it elects to purchase (such 10-business day period, the “Asset Sale Review Period”). Upon receipt by the Company of the
Asset Sale Notice, the Company shall (i) either (A) not enter into or agree to the Proposal governing the Asset Sale if Dell elects to purchase, or to have any of its Affiliates purchase, all of the properties or assets included in such
Asset Sale or (B) amend the Proposal governing the Asset Sale to exclude the properties or assets that Dell elects purchase, or to have any of its Affiliates purchase, and (ii) enter into an agreement with Dell or any of its Affiliates (as
designated by Dell) (A) on substantially the same financial terms as provided in the Proposal, as adjusted as set forth above for the specific properties or assets Dell elects to purchase, or to have any of its Affiliates purchase, and
(B) containing substantially the same representations and warranties, exclusivity (including any no-shop or other similar provision) and indemnities in favor of Dell or any of its Affiliates (as designated by Dell) as provided in the Proposal.

 (c) With respect to each Proposal for which Dell received a Company Notice, and for which the Company and its Subsidiaries
complied with all of the applicable procedures and requirements of this Agreement (the “Noticed Proposal”), in the event that (i) Dell does not deliver a Dell Notice or Asset Sale Notice, as applicable, to the Company prior to
the expiration of the applicable Review Period or (ii) Dell delivers to the Company prior to the expiration of the applicable Review Period an Asset Sale Notice that excludes any properties or assets that were subject of the applicable Proposal
(such excluded properties or assets, the “Excluded Assets”), then, and only then, the Company or its Subsidiary, as applicable, shall be free, for a period of 60 days following expiration of the applicable Review Period (the
“Noticed Proposal Period”), to enter into a Letter of Intent or other definitive agreement with respect to (x) in the case of clause (i), the Sale Event contemplated in such Noticed Proposal with the Person or
Persons subject of such Noticed Proposal on terms and conditions substantially similar to, and in any event not more favorable in any material respect to such Person or Persons than, the terms and conditions described in the Noticed Proposal and
(y) in the case of clause (ii), the Excluded Assets on terms and conditions substantially similar to, and in any event not more favorable in any material respect to such Person or Persons, as adjusted for the specific properties or
assets Dell elected to purchase, or to have any of its Affiliates purchase, as compared to all of the properties and assets subject to the applicable Proposal; provided, however, that no such Letter of Intent or other definitive
agreement shall provide for the payment of any fees and expenses, including any termination or break-up fees, or any similar provisions with any Person with respect to Dell’s rights hereunder with respect to a new Proposal resulting from a
Material Change (defined below) as set forth in Section 4(d) or that otherwise imposes limitations or restrictions on the Company’s or any of its Subsidiaries’ ability to comply with all of the terms of this Agreement.

  
 4 

 (d) If, during a Review Period or a Notice Proposal Period, any change or amendment to the
applicable Proposal or Noticed Proposal is made that individually or in the aggregate with any other changes or amendments, are more favorable in any material respect to the purchaser or purchasers (a “Material Change”), then such
Proposal or Noticed Proposal as changed or amended shall constitute a new Proposal subject to the terms and conditions of Sections 2, 3 and 4. 
 5. Additional Information Rights. The Company will furnish to Dell, upon reasonable notice, full information regarding any financing transaction, the proceeds of which may be used to repay
amounts owing under the Amended and Restated Note, and such other financial information as Dell may reasonably request. 
 6.
Termination. The rights described in this Agreement shall terminate upon the payment in full of the outstanding principal, accrued and unpaid interest and all fees and expenses under the Amended and Restated Note. 

7. Miscellaneous. 
 (a) Successors and Assigns. Neither party may assign its rights or obligations hereunder without the prior written consent of the other party. Subject to the foregoing, the terms and conditions of
this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 
 (b) Amendments and Waivers. Any term of this Agreement may be amended or waived only with the written consent of the Company and Dell. For purposes of this Agreement, no course of dealing between
the parties hereto and no delay on the part of any party hereto in exercising any rights hereunder shall operate as a waiver of the rights hereof. 
 (c) Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable,
the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties shall use their reasonable best efforts to replace such void or unenforceable
provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision. 

(d) Entire Agreement. This Agreement constitutes the entire agreement among the parties relating to the transactions contemplated
hereby and no party shall be liable or bound to any other party in any manner by any warranties, representations or covenants relating to the transactions contemplated hereby except as specifically set forth herein. The terms of any other agreement
between the parties are not affected by this Agreement and remain in full force and effect. 

  
 5 

 (e) Governing Law; Jurisdiction; Venue and Process. This Agreement and all acts and
transactions pursuant hereto shall be governed, construed, and interpreted in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof that would cause the laws of any other jurisdiction
to apply. Each party to this Agreement irrevocably and unconditionally agrees, for itself and its property, that the exclusive jurisdiction and venue of any action or proceeding arising out of or relating to this Agreement, the transactions
contemplated hereby or the subject matter hereof shall be the state courts of the State of Delaware or the federal courts of the United States located in the State of Delaware, and submits itself to the exclusive jurisdiction and venue of such
courts for the purposes of any such action or proceeding. Each party to this Agreement agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in any other jurisdictions by suit on the judgment or in any
other manner provided by applicable law. Each party to this Agreement irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any
action or proceeding arising out of or relating to this Agreement, the transactions contemplated hereby or the subject matter hereof in any court referred to above, including the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in the Purchase Agreement. Nothing in this Agreement will affect the right of any party to this Agreement to
serve process in any other manner permitted by law. 
 (f) Specific Performance. The Company acknowledges and agrees that
irreparable damage would occur and Dell would not have an adequate remedy at law in the event that any of the provisions of this Agreement were not performed by the Company in accordance with their specific terms or were otherwise breached, and that
monetary damages, even if available, would not be an adequate remedy therefor and therefore fully intend for specific performance to be the principal remedy for breaches of this Agreement. It is accordingly agreed that Dell shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 7(e), without proof of actual damages, this being
in addition to any other remedy to which they are entitled at law or in equity. The Company further agrees not to assert that a remedy of specific performance is unenforceable, invalid, contrary to law or inequitable for any reason, nor to object to
a remedy of specific performance on the basis that a remedy of monetary damages would provide an adequate remedy for any such breach. 
 (g) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

 (h) Facsimile or PDF Signatures. This Agreement may be executed and delivered by facsimile or PDF and upon such
delivery, the facsimile or PDF signature will be deemed to have the same effect as if the original signature had been delivered to the other party. 
 (i) Rules of Construction. The titles, captions and headings used in this Agreement are included for ease of reference only and will be disregarded in interpreting or construing this Agreement.
When a reference is made in this Agreement to a section, such reference shall be to a section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this
Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “hereto,” “hereby,” 

  
 6 

 
“herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this
Agreement. The term “or” is not exclusive. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Any agreement, instrument or law defined or referred to herein means such
agreement, instrument or law as from time to time amended, modified or supplemented, unless otherwise specifically indicated. References to a person are also to its permitted successors and assigns. No provision of this Agreement will be interpreted
in favor of, or against, any of the parties to this Agreement by reason of the extent to which any such party or its counsel participated in the drafting thereof or by reason of the extent to which any such provision is inconsistent with any prior
draft of this Agreement, and no rule of strict construction will be applied against any party hereto.

 Exhibit A 
 Form of Seventh Amended and Restated Registration Rights Agreement 

 Exhibit B 
 Certificate of Amendment to the Eighth Amended and Restated Certificate of IncorporationWarrant to Purchase Stock

 Exhibit 10.51 
 THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER UNITED STATES FEDERAL OR STATE SECURITIES LAWS AND MAY NOT BE OFFERED FOR SALE, SOLD, OR OTHERWISE
TRANSFERRED OR ASSIGNED FOR VALUE, DIRECTLY OR INDIRECTLY, NOR MAY THIS WARRANT OR THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT BE TRANSFERRED ON THE BOOKS OF THE COMPANY, WITHOUT REGISTRATION OF SUCH WARRANT OR SECURITIES, AS APPLICABLE,
UNDER ALL APPLICABLE UNITED STATES FEDERAL OR STATE SECURITIES LAWS OR COMPLIANCE WITH AN APPLICABLE EXEMPTION THEREFROM, SUCH COMPLIANCE, AT THE OPTION OF THE COMPANY, TO BE EVIDENCED BY AN OPINION OF STOCKHOLDER’S COUNSEL, IN A FORM
ACCEPTABLE TO THE COMPANY, THAT NO VIOLATION OF SUCH REGISTRATION PROVISIONS WOULD RESULT FROM ANY PROPOSED TRANSFER OR ASSIGNMENT. 
 GLASSHOUSE TECHNOLOGIES, INC. 
 WARRANT TO PURCHASE STOCK 

This Warrant is issued to Dell Products L.P., a Texas limited partnership, or its registered assigns (“Holder”), by
Glasshouse Technologies, Inc., a Delaware corporation (“Company”), on March 11, 2011 (the “Issue Date”). Capitalized terms used herein but not otherwise defined shall have the meaning given to such term in that
certain Securities Purchase Agreement dated as of March 6, 2008, as amended, by and between Company and Holder. 

Section 1. CERTAIN DEFINITIONS. As used in this Warrant, the following terms shall have the following meanings:

 “Common Stock” means the Common Stock, par value $0.001 per share, of Company. 

“Daily VWAP” means the daily dollar volume-weighted average price for the Common Stock on the national securities
exchange on which the Common Stock is then listed (the “Principal Market”) (or, if the Principal Market is not the principal trading market for the Common Stock, then on the principal securities exchange or securities market on
which the Common Stock is then traded) during the period beginning at 9:30 a.m. (New York City time) (or such other time as such Principal Market publicly announces is the official open of trading), and ending at 3:59 p.m. (New York City time) (or
one minute before such other time as such Principal Market publicly announces is the official close of trading) as reported by Bloomberg.com through its “Volume at Price” function (subject to adjustment to reflect dividends, stock splits,
stock combinations or other similar transactions) of the Common Stock pursuant to an individual transaction, or, if no dollar volume-weighted average price is reported for the Common Stock by Bloomberg.com for such hours, the average of the highest
closing bid price and the lowest closing ask price of any of the market makers for such security as reported in the “pink sheets” by Pink Sheets LLC. If the Daily VWAP cannot be calculated for the Common Stock on such date on any of the
foregoing bases, the Daily VWAP of the Common Stock on such date shall be the fair market value as mutually determined by Company and Holder. 

 “Exercise Price” means a price equal to 90% of the initial public offering
price per share at which Common Stock was issued and sold to the public in a Qualifying IPO. 
 “Qualifying
IPO” shall have the definition of a Qualified Public Offering as set forth in Company’s Certificate of Incorporation, as amended. 
 “Trading Day” means any day on which the Common Stock is traded on the Principal Market, or, if the Principal Market is not the principal trading market for the Common Stock, then on the
principal securities exchange or securities market on which the Common Stock is then traded; provided that “Trading Day” shall not include any day on which the Common Stock is scheduled to trade on such exchange or market for less than 4.5
hours or any day that the Common Stock is suspended from trading during the final hour of trading on such exchange or market (or if such exchange or market does not designate in advance the closing time of trading on such exchange or market, then
during the hour ending at 4:00 p.m., New York City time). 
 Section 2. PURCHASE OF SHARES. Subject to the terms
and conditions set forth in this Warrant, Holder is entitled to purchase from Company at the Exercise Price up to that number of shares Common Stock determined by dividing $10,000,000 by the Exercise Price. The number of shares of Common Stock
issuable pursuant to this Section (the “Shares”) shall be subject to adjustment pursuant to Section 7. 

Section 3. EXERCISE PERIOD. Except as provided below, this Warrant is exercisable at any time and from time to time after
the closing of a Qualifying IPO. 
 This Warrant shall immediately expire and terminate with no further action on the part of
Company or Holder at the earliest of (the “Termination Event”) (i) three (3) years after the closing of a Qualifying IPO (the “Qualifying IPO Termination”) or (ii) the closing of an Extraordinary
Transaction prior to a Qualifying IPO. The period during which this Warrant is exercisable is referred to as the “Exercise Period.” 
 Section 4. METHOD OF EXERCISE. During the Exercise Period, Holder may exercise, in whole or in part, the purchase rights evidenced by this Warrant. Such exercise shall be effected by
surrender of this Warrant at the principal office of Company together with a Notice of Election attached to this Warrant, and if Holder is deemed to have exercised this Warrant in full pursuant to this Section, Holder shall receive, in either case
without the payment by Holder of any additional consideration, Shares equal to the value of this Warrant (or the portion of this Warrant being canceled). Upon any such surrender or exercise, Company shall issue to Holder of this Warrant a number of
Shares computed using the following formula: 
  

							
		  	Y (A - B)	  		  	
	X =	  	        A	  		  	

  

					
	 Where:
	  	X=	  	The number of Shares to be issued to Holder pursuant to this net exercise;
			
		  	Y=	  	The number of Shares in respect of which the net issue election is made;

  
 2 

					
		  	A=	  	The fair market value of one Share at the time the net issue election is made; and
			
		  	B=	  	The Exercise Price (as adjusted to the date of the net issuance).

 For purposes of this Section, the fair market value of one Share as of a particular date shall be determined based upon
the average of the Daily VWAP for the 20 Trading Day period ending on the Trading Day immediately prior to the date of the Notice of Election. 
 If Holder has not otherwise notified Company or exercised this Warrant in full prior to the Qualifying IPO Termination, then Holder shall be deemed to have exercised this Warrant in full pursuant to this
Section immediately prior to the Qualifying IPO Termination, without any action, election or notice required by Holder. 

Section 5. HSR COMPLIANCE. Company acknowledges that exercise of this Warrant by Holder may subject Holder to the filing
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). As such, exercise of this Warrant is subject to compliance by Holder with all applicable filing requirements and the expiration of
all waiting periods under the HSR Act (the “HSR Act Restrictions”). If, on or before the expiration of this Warrant, Holder has sent a Notice of Election to Company and Holder has not been able to effect the exercise of this Warrant
prior to its expiration because of HSR Act Restrictions, Holder shall be entitled to effect the exercise of this Warrant in accordance with the procedures contained herein notwithstanding the fact that the exercise of this Warrant would be effected
after the expiration of the Warrant. Company will cooperate with Holder in making all applicable filings under the HSR Act, provided, however, that Holder shall pay all applicable filing fees. 

Section 6. DELIVERY OF CERTIFICATES AND NEW WARRANT. Promptly after Holder exercises or converts this Warrant,
Company shall deliver to Holder the certificate(s) for the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired. 

Section 7. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The number of and kind of securities purchasable upon
exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows: 
 (a)
Subdivisions, Combinations and Other Issuances. If Company shall at any time prior to the expiration of this Warrant subdivide its Common Stock, by split-up or otherwise, or combine its Common Stock, or issue additional shares of its Common
Stock as a dividend with respect to any shares of its Common Stock, the number of Shares issuable on the exercise of this Warrant shall immediately be proportionately increased in the case of a subdivision or stock dividend, or proportionately
decreased in the case of a combination. Appropriate adjustments shall also be made to the Exercise Price such that the aggregate Exercise Price payable for the total number of Shares purchasable under this Warrant (as adjusted) shall remain the
same. Any adjustment under this Section shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the
making of such dividend. 

  
 3 

 (b) Reclassification, Reorganization and Consolidation. In case of any
reclassification, capital reorganization, or change in the Common Stock of Company (other than as a result of a subdivision, combination, or stock dividend provided for in Section 7(a) above), then, as a condition of such
reclassification, reorganization, or change, lawful provision shall be made, and duly executed documents evidencing the same from Company or its successor shall be delivered to Holder, so that Holder shall have the right at any time prior to the
expiration of this Warrant to purchase, at a total Exercise Price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and other securities and property receivable in connection with such reclassification,
reorganization, or change of the same number of shares of Common Stock as were purchasable by Holder immediately prior to such reclassification, reorganization, or change. In any such case appropriate provisions shall be made with respect to the
rights and interest of Holder so that the provisions of this Warrant shall be applicable after such reclassification, reorganization, or change with respect to any shares of stock or other securities and property deliverable upon exercise of this
Warrant, and appropriate adjustments shall be made to the Exercise Price such that the aggregate Exercise Price payable for the total number of Shares purchasable under this Warrant (as adjusted) shall remain the same. 

(c) Distributions of Other Property. In case Company shall distribute to all holders of its Common Stock
(including any such distribution made in connection with a consolidation or merger in which Company is the continuing corporation) evidences of its indebtedness or assets (excluding cash dividends or distributions payable out of consolidated
earnings or earned surplus and dividends or distributions referred to in Section 7(a) above) or rights, options, or warrants, or convertible or exchangeable securities containing the right to subscribe for or purchase debt securities,
assets, or other securities of Company (excluding those referred to in Section 7(a) above), then in lieu of an adjustment in the number of Shares purchasable upon the exercise of this Warrant, Holder upon the exercise of this Warrant at
any time after such distribution shall be entitled to receive from Company the stock or other securities to which Holder would have been entitled if Holder had exercised the Warrant immediately prior to such distribution, all subject to further
adjustment as provided in this Section; provided, that no adjustment in respect of cash dividends or interest on such stock or other securities shall be made during the term of this Warrant or upon the exercise of this Warrant. 

(d) Notice of Certain Events. If, at any time prior to the expiration or exercise in full of this Warrant, (i) Company shall
declare any dividend on the Common Stock payable in cash or shares of Common Stock or other capital stock of Company; or (ii) Company shall authorize the issuance to all holders of shares of Common Stock of rights, options, or warrants to
subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; or (iii) Company shall authorize the distribution to all holders of shares of Common Stock evidences of its indebtedness or assets; or
(iv) the Board of Directors of Company shall have approved any consolidation or merger to which Company is a party and for which approval of any stockholders of Company is required, or any sale or lease of all or substantially all of the assets
of Company or any reclassification or change of Common Stock issuable upon exercise of this Warrant (other than a change in par value or as a result of a subdivision or combination), or a 

  
 4 

 
tender offer or exchange offer for shares of Common Stock; or (v) the voluntary or involuntary dissolution, liquidation, or winding up of Company occurs; or (vi) Company proposes to
take any action that would require an adjustment in the number or kind of securities issuable upon exercise of this Warrant pursuant to this Section; then Company shall cause to be given to Holder, at least 20 calendar days prior to the applicable
record date specified, or promptly in the case of events for which there is no record date, a written notice stating (A) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such dividends, rights,
options, warrants, or distribution are to be determined, or (B) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock, or (C) the date on which any such consolidation, merger, sale, lease,
reclassification, change, dissolution, liquidation, or winding up is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock shall be entitled to exchange such shares for
securities or other property, if any, deliverable upon such consolidation, merger, sale, transfer, lease, reclassification, change, dissolution, liquidation, or winding up. 
 (e) Notice of Adjustment. When any adjustment is required to be made in the number or kind of Shares or in the Exercise Price, Company shall promptly notify Holder of such event and of the number
of Shares or other securities or property purchasable after such required adjustment upon exercise of this Warrant and the Exercise Price for such adjusted number or kind of Shares. 

Section 8. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or scrip representing fractional shares shall be issued upon
the exercise of this Warrant, but, in lieu of such fractional shares, Company shall make a cash payment for such fractional shares on the basis of the Exercise Price then in effect. 

Section 9. NO STOCKHOLDER RIGHTS. Prior to exercise of this Warrant, Holder shall not be entitled to any rights of a
stockholder with respect to the Shares, including (without limitation) the right to vote such Shares, receive dividends or other distributions on such Shares, exercise preemptive rights or be notified of stockholder meetings, and such Holder shall
not be entitled to any notice or other communication concerning the business or affairs of Company. However, nothing in this Section shall limit the right of Holder to be provided the notices required under this Warrant. 

Section 10. LIMITATION OF LIABILITY. No provision of this Warrant, in the absence of affirmative action by Holder to
purchase the Shares, and no mere enumeration in this Warrant of the rights or privileges of Holder, shall give rise to any liability of such Holder for the Exercise Price, whether such liability is asserted by Company or by creditors of Company.

 Section 11. TRANSFERS OF WARRANT AND SHARES. Except as subject to compliance with applicable federal and state
securities laws, this Warrant and all rights under this Warrant are transferable in whole or in part by Holder to any person or entity upon written notice to Company. The transfer shall be recorded on the books of Company upon the surrender of this
Warrant, properly endorsed, to Company at its principal offices, and the payment to Company of all transfer taxes and other governmental charges imposed on such transfer. In the event of a partial transfer, Company shall issue to the holders one or
more appropriate new warrants.
