SECTION 3. EXERCISE OF THE PURCHASE RIGHTS. 

  
 3 








 (a) Exercise. The purchase rights set forth in this Agreement are exercisable by the
Warrantholder, in whole or in part, at any time, or from time to time, during the Warrant Term, by tendering to the Company at its principal office a notice of exercise in the form attached hereto as Exhibit I (the “Notice of
Exercise”), duly completed and executed. Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in accordance with the terms set forth below, and in no event later than three (3) business days thereafter,
the Company shall issue to the Warrantholder a certificate for the number of shares of Common Stock purchased and shall execute the acknowledgment of exercise in the form attached hereto as Exhibit II (the “Acknowledgment of
Exercise”) indicating the number of shares which remain subject to future purchases, if any. 
 The Purchase Price may be paid at
the Warrantholder’s election either (i) by cash or check, or (ii) by surrender of all or a portion of the Warrant for shares of Common Stock to be exercised under this Agreement and, if applicable, an amended Agreement representing
the remaining number of shares purchasable hereunder, as determined below (“Net Issuance”). If the Warrantholder elects the Net Issuance method, the Company will issue Common Stock in accordance with the following formula: 

 

					
		  		  	X = Y(A-B)
		  		  	 A

			
	Where:	  	X	  	the number of shares of Common Stock to be issued to the Warrantholder.
			
		  		  	Y = the number of shares of Common Stock requested to be exercised under this Agreement (including the number of shares to be cancelled in payment of the Purchase Price).
			
		  		  	A = the fair market value of one (1) share of Common Stock at the time of issuance of such shares of Common Stock.
			
		  	B =	  	the Exercise Price.

 For purposes of the above calculation, the fair market value per share of Common Stock shall mean: 

(i) if the Common Stock is traded on the New York Stock Exchange, the American Stock Exchange, any exchange operated by The
NASDAQ Stock Market LLC or any other securities exchange, the fair market value shall be deemed to be the average of the closing prices over a five (5) day period ending three (3) days before the day the fair market value of the Common
Stock is being determined; or 
 (ii) if at any time the Common Stock is not listed on the New York Stock Exchange, the
American Stock Exchange, any exchange operated by The NASDAQ Stock Market LLC or any other securities exchange, the fair market value of such Common Stock shall be fair market value of Common Stock as determined in good faith by the Company’s
Board of Directors (provided, that if Warrantholder disagrees with the fair market value determined by the Company’s Board of Directors Warrantholder may solicit, from an appraiser reasonably acceptable to the Company, an independent


  
 4 








 
appraisal of the fair market value of the Common Stock and, if such valuation is higher, Warrantholder may substitute the Board of Directors’ fair market value determination with that of the
independent appraiser), unless the Company shall consummate a Merger Event pursuant to which the Company is not the surviving party, in which case the fair market value of Common Stock shall be deemed to be the per share value received by the
holders of the Company’s Common Stock on a Common Stock-equivalent basis pursuant to such Merger Event. 
 Upon partial exercise by
either cash or Net Issuance, the Company shall promptly issue an amended Agreement representing the remaining number of shares purchasable hereunder. All other terms and conditions of such amended Agreement shall be identical to those contained
herein, including, but not limited to the Effective Date hereof. 
 (b) Exercise Prior to Expiration. To the extent that the
Warrantholder has not exercised its purchase rights under this Agreement to all Common Stock subject hereto, and if the fair market value of one share of the Common Stock is greater than the Exercise Price then in effect, this Agreement shall be
deemed automatically exercised pursuant to Section 3(a) (even if not surrendered) immediately before the expiration of the Warrant Term. For purposes of such automatic exercise, the fair market value of one share of the Common Stock upon such
expiration shall be determined pursuant to Section 3(a). To the extent this Agreement or any portion thereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to promptly notify the Warrantholder of the
number of shares of Common Stock, if any, the Warrantholder is to receive by reason of such automatic exercise. 
 SECTION 4.
RESERVATION OF SHARES. 
 From and after the Effective Date, the Company will at all times have authorized and reserved a sufficient number
of shares of its Common Stock to provide for the exercise of the rights to purchase Common Stock as provided for herein. 
 SECTION
5. NO FRACTIONAL SHARES OR SCRIP. 
 No fractional shares or scrip representing fractional shares shall be issued upon the exercise of
the Warrant provided for in this Agreement, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the fair market value of the share, as determined in accordance with Section 3. 

SECTION 6. NO RIGHTS AS SHAREHOLDER/STOCKHOLDER. 

This Agreement does not entitle the Warrantholder to any voting rights or other rights as a shareholder/stockholder of the Company prior to
the exercise of the Warrant. 
 SECTION 7. WARRANTHOLDER REGISTRY. 

The Company shall maintain a registry showing the name and address of the registered holder of the Warrant. Warrantholder’s initial
address, for purposes of such registry, is set forth in Section 12(g). Warrantholder may change such address by giving written notice of such changed address to the Company. 

  
 5 








 SECTION 8. ADJUSTMENT RIGHTS. 

The Exercise Price and the number of shares of Common Stock purchasable hereunder are subject to adjustment, as follows: 

(a) Merger Event. If at any time there shall be a Merger Event, then, as a part of such Merger Event, lawful provision shall be made so
that the Warrantholder shall thereafter be entitled to receive, upon exercise of the Warrant, the kind, amount and value of shares of common stock or other securities or property of the successor, surviving or purchasing corporation resulting from,
or participating in, such Merger Event that would have been issuable if Warrantholder had exercised the Warrant immediately prior to the Merger Event. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board
of Directors) shall be made in the application of the provisions of this Agreement with respect to the rights and interests of the Warrantholder after the Merger Event to the end that the provisions of this Agreement (including adjustments of the
Exercise Price) shall be applicable in their entirety, and to the greatest extent possible. Without limiting the foregoing, in connection with any Merger Event, upon the closing thereof, the successor, surviving or purchasing entity shall assume the
obligations of this Agreement. The provisions of this Section 8(a) shall similarly apply to successive Merger Events. In connection with a Merger Event and upon Warrantholder’s written election to the Company, the Company shall cause the
Warrant to be exchanged for the consideration that Warrantholder would have received if Warrantholder chose to exercise its right to have shares issued pursuant to the Net Issuance provisions of this Agreement without actually exercising such right,
acquiring such shares and exchanging such shares for such consideration. 
 (b) Reclassification of Shares. Except as set forth in
Section 8, if the Company at any time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities as to which purchase rights under this Agreement exist into the same or a different
number of securities of any other class or classes, this Agreement shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were
subject to the purchase rights under this Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change. 

(c) Subdivision or Combination of Shares. If the Company at any time shall combine or subdivide its Common Stock purchasable hereunder,
(i) in the case of a subdivision, the Exercise Price shall be proportionately decreased, or (ii) in the case of a combination, the Exercise Price shall be proportionately increased. 

(d) Stock Dividends. If the Company at any time while the Warrant is outstanding and unexpired shall: 

(i) pay a dividend with respect to the Common Stock payable in Common Stock, then the Exercise Price shall be adjusted, from
and after the date of determination of stockholders entitled to receive such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the
numerator of which shall be the total number of 

  
 6 








 
shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock outstanding
immediately after such dividend or distribution; or 
 (ii) make any other distribution with respect to the Common Stock,
except any distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision shall be made by the Company such that the Warrantholder shall receive upon exercise of the Warrant a proportionate
share of any such distribution as though it were the holder of the Common Stock as of the record date fixed for the determination of the stockholders of the Company entitled to receive such distribution. 

(e) Antidilution Rights. Antidilution rights applicable to the Common Stock purchasable hereunder, if any, are as set forth in the
Charter. The Company shall promptly provide the Warrantholder with a copy of any restatement, amendment, modification or waiver of the Charter; provided, that no such restatement, amendment, modification or waiver shall impair or reduce the
antidilution rights, if any, applicable to the Common Stock unless such restatement, amendment, modification or waiver affects the rights of Warrantholder with respect to the Common Stock purchasable hereunder in the same manner as it affects all
other holders of the Common Stock. The Company shall, within ten (10) business days of the end of each fiscal quarter following the Effective Date in which an antidilution adjustment with respect to the Common Stock purchasable hereunder
occurred pursuant to the Charter, provide Warrantholder with written notice of any issuance of its stock or other equity security during such fiscal quarter that triggered such an antidilution adjustment, which notice shall include (a) the
price at which such stock or security was sold, (b) the number of shares issued, and (c) such other information as reasonably necessary for Warrantholder to verify that such antidilution adjustment occurred and the amount of any such
adjustment. For the avoidance of doubt, there shall be no duplicate antidilution adjustment pursuant to this subsection (e), the forgoing subsection (d) and the Charter. 

(f) Notice of Adjustments. If (i) the Company shall declare any dividend or distribution upon its Common Stock, whether in stock,
cash, property or other securities (assuming Warrantholder consents to a dividend involving cash, property or other securities under the Loan Agreement, if such consent is then required by the terms of the Loan Agreement); (ii) the Company
shall offer for subscription pro rata to the holders of Common Stock any additional shares of stock of any class or other rights; (iii) there shall be any Merger Event or the Company shall sell, lease, license or otherwise transfer all or
substantially all of its assets; or (iv) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall send to the Warrantholder: (A) at least fifteen
(15) 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, distribution, subscription rights (specifying the date on which the holders of Common Stock shall be
entitled thereto) or for determining rights to vote in respect of such Merger Event, dissolution, liquidation or winding up; and (B) in the case of any such Merger Event, sale, lease, license or other transfer of all or substantially all of the
Company’s assets, dissolution, liquidation or winding up, at least fifteen (15) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of Common Stock shall be entitled to
exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding up). 

  
 7 








 Each such written notice shall set forth, in reasonable detail, (i) the event requiring the
notice, and (ii) if any adjustment is required to be made, (A) the amount of such adjustment, (B) the method by which such adjustment was calculated, (C) the adjusted Exercise Price (if the Exercise Price has been adjusted), and
(D) the number of shares subject to purchase hereunder after giving effect to such adjustment, and shall only be provided in the manner set forth in Section 12(g)(i). 

(g) Timely Notice. Failure to timely provide such notice required by subsection (f) above shall entitle Warrantholder to retain
the benefit of the applicable notice period notwithstanding anything to the contrary contained in any insufficient notice received by Warrantholder. 

SECTION 9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY. 

(a) Reservation of Common Stock. The Common Stock issuable upon exercise of the Warrantholder’s rights has been, or in accordance
with Section 4, will be duly and validly reserved and, when issued in accordance with the provisions of this Agreement, will be validly issued, fully paid and non-assessable, and will be free of any taxes, liens, charges or encumbrances of any

true, correct and complete copies of its Charter and current bylaws. The issuance of certificates for shares of Common Stock upon exercise of the Warrant and payment of the Purchase Price shall be made without charge to the Warrantholder for any
issuance tax in respect thereof, or other cost incurred by the Company in connection with such exercise and the related issuance of shares of Common Stock; provided, that the Company shall not be required to pay any tax which may be payable in
respect of any transfer and the issuance and delivery of any certificate in a name other than that of the Warrantholder. 
 (b) Due

authorized by all necessary corporate action on the part of the Company. The execution and delivery by the Company of this Agreement: (1) does not violate the Company’s Charter or current bylaws; (2) does not contravene any law or
governmental rule, regulation or order applicable to it; and (3) does not and will not contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument to which it is a party or by which it is

agreement.

(j) Listing of Shares. The Common Stock is listed for trading on The NASDAQ Global Market as of the Effective Date and the Company
shall maintain such listing through the Warrant Term. 
 (k) Registration Rights. If, prior to the date on which Warrantholder
may sell all shares of Common Stock issuable upon exercise of this Warrant without restriction pursuant to Rule 144 promulgated under the Act (assuming that Warrantholder were to exercise this Warrant by Net Issuance), the Company proposes to
register under the Act for resale any shares of Common Stock held by any person (other than the Company) (other than a registration statement on Form S-8 or its successor or any other form for a similar limited purpose), then the Company shall give
Warrantholder reasonable prior written notice of such proposed registration and shall, upon written request of the Warrantholder given within five days after the Company provides such notice, permit Warrantholder to include (but Warrantholder shall
not be obligated to include) all or a portion (as determined by Warrantholder in its sole discretion) of the shares of Common Stock issuable upon exercise of this Warrant (exclusive of any shares of Common Stock theretofore registered pursuant to
the provisions of this Section 9(k)) in such registration on a pari passu basis with the other holders participating therein and on the same terms and conditions as applicable to such other holders; provided that the Company will have the right
to postpone or withdraw any such registration without obligation to the Warrantholder. 
 SECTION 10. REPRESENTATIONS AND COVENANTS
OF THE WARRANTHOLDER. 
 This Agreement has been entered into by the Company in reliance upon the following representations and covenants of
the Warrantholder: 
 (a) Investment Purpose. The right to acquire Common Stock or the Common Stock issuable upon exercise of the
Warrantholder’s rights contained herein has been, and such shares will be, acquired for investment and not with a view to, or for sale in connection with, the distribution of any part thereof, and the Warrantholder has no present intention of
selling or engaging in, or any agreement, undertaking or commitment with respect to, any public distribution of the same. 
 (b) Private
Issue. The Warrantholder understands (i) that the Common Stock issuable upon exercise of this Agreement is not registered under the Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this
Agreement will be exempt from the registration and qualifications requirements thereof, and (ii) that the Company’s reliance on such exemption is predicated on the representations set forth in this Section 10. 

  
 10 








 (c) Financial Risk. The Warrantholder has sufficient knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of its investment, and has the ability to bear the economic risks of its investment, in the Company. Such Warrantholder has made detailed inquiry concerning the Company, its
business and its personnel and the officers of the Company have made available to such Warrantholder any and all written information which it has requested and have answered to such Warrantholder’s satisfaction all inquiries made by such
Warrantholder. 
 (d) Risk of No Registration. Without prejudice to Section 9(k), the Warrantholder understands that if the
Company does not register shares of its capital stock with the SEC pursuant to Section 12 of the Securities Exchange Act of 1934 (the “1934 Act”), or file reports pursuant to Section 15(d) of the 1934 Act, or if a
registration statement covering shares of its capital stock under the Act covering the Warrant granted pursuant to this Agreement and the shares of Common Stock issuable upon exercise of the Warrant granted pursuant to this Agreement is not in
effect when it desires to sell (i) the Warrant granted pursuant to this Agreement or (ii) the shares of Common Stock issuable upon exercise of such Warrant, it may be required to hold such securities for an indefinite period. The
Warrantholder also understands that any sale of (A) such Warrant or (B) the shares of Common Stock issued or issuable hereunder which might be made by it in reliance upon Rule 144 under the Act may be made only in accordance with the terms
and conditions of that Rule. 
 (e) Accredited Investor. Warrantholder is an “accredited investor” within the meaning of
Rule 501 of Regulation D, as presently in effect, under the Act. 
 (f) No Short Sales. The Warrantholder has not engaged, and will
not engage, in “short sales” of the Common Stock of the Company. The term “short sale” shall mean any sale of a security which the seller does not own or any sale which is consummated by the delivery of a security borrowed by, or
for the account of, the seller. 
 SECTION 11. TRANSFERS. 

Subject to compliance with the provisions of this Agreement and applicable federal and state securities laws, this Agreement and all rights
hereunder are transferable, in whole or in part, without charge to the holder hereof (except for transfer taxes) upon surrender of this Agreement properly endorsed. Subject to such compliance, each taker and holder of this Agreement, by taking or
holding the same, consents and agrees that this Agreement, when endorsed in blank, shall be deemed negotiable, and that the holder hereof, when this Agreement shall have been so endorsed and its transfer recorded on the Company’s books, shall
be treated by the Company and all other persons dealing with this Agreement as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented by this Agreement. The transfer of this Agreement shall be
recorded on the books of the Company upon receipt by the Company of a notice of transfer in the form attached hereto as Exhibit III (the “Transfer Notice”), at its principal offices and the payment to the Company of all transfer taxes and
other governmental charges imposed on such transfer. Until the Company receives such Transfer Notice, the Company may treat the registered owner hereof as the owner for all purposes. 

  
 11 








 Each certificate representing shares acquired upon exercise of such Warrant shall bear a legend substantially in
the following form: 
 “The securities represented by this certificate have not been registered under the Securities Act of 1933, as
amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such securities are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such
registration is not required.” 
 SECTION 12. MISCELLANEOUS.

executed and delivered by the Company on the date hereof. This Agreement shall be binding upon any successors or assigns of the Company.

suit in equity and/or by action at law, including but not limited to an action for damages as a result of any such default, and/or an action for specific performance for any default where the non-defaulting party will not have an adequate remedy at
law and where damages will not be readily ascertainable. Each party hereto expressly agrees that it shall not oppose an application by the other party or any other person entitled to the benefit of this Agreement requiring specific performance of
any or all provisions hereof or enjoining a party from continuing to commit any such breach of this Agreement. 
 (c) No Impairment of
Rights. The Company will not, by amendment of its Charter or through any other means, avoid or seek to avoid the observance or performance of any of the terms of this Agreement, but will at all times in good faith assist in the carrying out of
all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of the Warrantholder against impairment.

 (h) Entire Agreement; Amendments. This Agreement constitutes the
entire agreement and understanding of the parties hereto in respect of the subject matter hereof, and supersedes and replaces in their entirety any prior proposals, term sheets, letters, negotiations or other documents or agreements, whether written
or oral, with respect to the subject matter hereof (including the proposal letter dated February 17, 2016 between the Warrantholder and the Company). None of the terms of this Agreement may be amended except by an instrument executed by each of
the parties hereto. 
 (i) Headings. The various headings in this Agreement are inserted for convenience only and shall not affect
the meaning or interpretation of this Agreement or any provisions hereof. 
 (j) Advice of Counsel. Each of the parties represents to
each other party hereto that it has discussed (or had an opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(n), 12(o), 12(p), 12(q) and 12(r). 

(k) No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the
event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement. 
 (l) No Waiver. No omission or delay by either party at any time to enforce any
right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by the other party at any time designated, shall be a waiver of any such right or remedy to which such party is entitled, nor shall it in
any way affect the right of such party to enforce such provisions thereafter. 
 (m) Survival. All agreements, representations and
warranties contained in this Agreement or in any document delivered pursuant hereto shall be for the benefit of Warrantholder and shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.

 (n) Governing Law. This Agreement has been negotiated and delivered to Warrantholder in the State of California, and shall have
been accepted by Warrantholder in the State of California. Delivery of Common Stock to Warrantholder by the Company under this Agreement is due in the State of California. This Agreement shall be governed by, and construed and enforced in accordance
with, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction. 

(o) Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Agreement may be brought in any
state or federal court of competent jurisdiction 

  
 14 








 
located in the State of California. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (a) consents to personal jurisdiction in San Mateo County,
State of California; (b) waives any objection as to jurisdiction or venue in San Mateo County, State of California; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and
(d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance
with the requirements for notice set forth in Section 12(g), and shall be deemed effective and received as set forth in Section 12(g). Nothing herein shall affect the right to serve process in any other manner permitted by law or shall
limit the right of either party to bring proceedings in the courts of any other jurisdiction. 
 (p) Mutual Waiver of Jury Trial.
Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration
rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF THE COMPANY AND WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM,
COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST WARRANTHOLDER OR ITS ASSIGNEE OR BY WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY. This waiver extends to all such
Claims, including Claims that involve Persons other than the Company and Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and Warrantholder; and any Claims for damages, breach of contract,
specific performance, or any equitable or legal relief of any kind, arising out of this Agreement. 
 (q) Arbitration. If the Mutual
Waiver of Jury Trial set forth in Section 12(p) is ineffective or unenforceable, the parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of JAMS (the “Rules”),
such arbitration to occur before one arbitrator, which arbitrator shall be a retired California state judge or a retired Federal court judge. Such proceeding shall be conducted in California with California rules of evidence and discovery applicable
to such arbitration. The decision of the arbitrator shall be binding on the parties, and shall be final and non-appealable to the maximum extent permitted by law. Any judgment rendered by the arbitrator may be entered in a court of competent
jurisdiction and enforced by the prevailing party as a final judgment of such court. 
 (r) Prearbitration Relief. In the event
Claims are to be resolved by arbitration, either party may seek from a court of competent jurisdiction identified in Section 12(o), any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to
the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by binding arbitration. 
 (s)
Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed
an original, but all of which counterparts shall constitute but one and the same instrument. 

  
 15 








 (t) Specific Performance. The parties hereto hereby declare that it is impossible to
measure in money the damages which will accrue to a party hereto by reason of the other party’s failure to perform any of the obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by
either party hereto. If a party hereto institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action or proceeding is brought hereby waives the claim or defense therein that such party has an
adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.
