 APPLIED IMAGING CORP. 
 WARRANT TO PURCHASE
             SHARES OF 
 COMMON STOCK, PAR VALUE $0.001 PER SHARE

 For VALUE RECEIVED,
                     (“Warrantholder”), is entitled to purchase, subject to the provisions of this Warrant, from Applied Imaging
Corp., a Delaware corporation (“Company”), at any time from and after six month anniversary of the Closing Date (as defined in the Purchase Agreement, dated March 14, 2006 among the Company, the Warrantholder and other purchasers of
the Company’s securities (the “Purchase Agreement”)) (and not later than 5:00 P.M., Eastern time, on the Expiration Date (as defined above), at an exercise price per share equal to $2.52 (the exercise price in effect being herein
called the “Warrant Price”),              shares (“Warrant Shares”) of the Company’s Common Stock, par value $0.001 per share (“Common Stock”). The
number of Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time as described herein. 
 Section 1. Records. The Company shall maintain records for the transfer and recording of the Warrant. Upon the initial issuance of this Warrant, the Company shall issue and record the Warrant in the name
of the Warrantholder. 
 Section 2. Transfers. As provided herein, this Warrant may be transferred only pursuant to a
registration statement filed under the Securities Act of 1933, as amended (the “Securities Act”), or an exemption from such registration. Subject to such restrictions, the Company shall transfer this Warrant from time to time upon the
books to be maintained by the Company for that purpose, upon surrender thereof for transfer properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including,
if required by the Company, an opinion of its counsel to the effect that such transfer is exempt from the registration requirements of the Securities Act, to establish that such transfer is being made in accordance with the terms hereof, and a new
Warrant shall be issued to the transferee and the surrendered Warrant shall be canceled by the Company. 

 Section 3. Exercise of Warrant. Subject to the provisions hereof, the Warrantholder may
exercise this Warrant in whole or in part at any time prior to its expiration upon surrender of the Warrant, together with delivery of the duly executed Warrant exercise form attached hereto as Appendix A (the “Exercise Agreement”) and
payment by cash, certified check or wire transfer of funds (or by cashless exercise as provided in Section 17 below) for the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal
business hours on any business day at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the Warrantholder). The Warrant Shares so purchased shall be deemed to be issued to
the Warrantholder or the Warrantholder’s designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered (or evidence of loss, theft or destruction thereof and security or
indemnity satisfactory to the Company), the Warrant Price shall have been paid and the completed Exercise Agreement shall have been delivered. Certificates for the Warrant Shares so purchased, representing the aggregate number of shares specified in
the Exercise Agreement, shall be delivered to the Warrantholder within a reasonable time, not exceeding five business days after the Warrantholder has delivered all documents reasonably requested by the Company’s transfer agent and its counsel,
after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the Warrantholder and shall be registered in the name of the Warrantholder or such other name as shall be designated
by the Warrantholder. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the Warrantholder a new Warrant
representing the number of shares with respect to which this Warrant shall not then have been exercised. As used herein, “business day” means a day, other than a Saturday or Sunday, on which banks in San Francisco are open for the general
transaction of business. Each exercise hereof shall constitute the re-affirmation by the Warrantholder that the representations and warranties contained in Section 5 of the Purchase Agreement (as defined below) are true and correct in all
material respects with respect to the Warrantholder as of the time of such exercise. 
 Section 4. Compliance with the Securities Act
of 1933. Except as provided in the Purchase Agreement (as defined below), the Company may cause the legend set forth on the first page of this Warrant to be set forth on each Warrant or similar legend on any security issued or issuable upon
exercise of this Warrant, unless counsel for the Company is of the opinion as to any such security that such legend is unnecessary. 
 Section 5. Payment of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the Warrantholder in respect of which such shares are issued,
and in such case, the Company shall not be required to issue or deliver any certificate for Warrant Shares or any Warrant until the person requesting the same has paid to the Company 
  

 -2- 

 the amount of such tax or has established to the Company’s reasonable satisfaction that such tax has been paid. The
Warrantholder shall be responsible for income taxes due under federal, state or other law, if any such tax is due. 
 Section 6.
Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and upon cancellation of the mutilated Warrant, or in lieu of and substitution for the
Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and
with respect to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with respect thereto, if requested by the Company. 
 Section 7. Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this
Section 7, out of the authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of purchase represented by this Warrant. The Company agrees that all Warrant Shares issued upon due exercise of
the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company. 
 Section 8. Adjustments. Subject and pursuant to the provisions of this Section 8, the Warrant Price and number of Warrant Shares subject
to this Warrant shall be subject to adjustment from time to time as set forth hereinafter. 
 (a) If the Company shall, at any time or from
time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares
of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation), then the number of Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in effect immediately prior to the date upon which such change shall become effective, shall be adjusted by the
Company so that the Warrantholder thereafter exercising the Warrant shall be entitled to receive the number of shares of Common Stock or other capital stock which the Warrantholder would have received if the Warrant had been exercised immediately
prior to such event upon payment of a Warrant Price that has been adjusted to reflect a fair allocation of the economics of such event to the Warrantholder. Such adjustments shall be made successively whenever any event listed above shall occur.

 (b) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with
another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another corporation shall be effected, then, as a condition of such reorganization,
reclassification, consolidation, merger, sale, transfer or other disposition, lawful 
  

 -3- 

 and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive
upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with
respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of
the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such
consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation
purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Warrantholder, at the last address of the Warrantholder appearing on the books of the Company, such shares of
stock, securities or assets as, in accordance with the foregoing provisions, the Warrantholder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive
reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions. 
 (c) In case the Company shall fix a
payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or
assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 8(a)), or subscription rights or warrants, the Warrant Price to be in effect
after such payment date shall be determined by multiplying the Warrant Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the
Market Price (as defined below) per share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company’s Board of Directors in good faith) of said assets or evidences of indebtedness so
distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Market Price per share of Common Stock immediately prior to such payment date.
“Market Price” as of a particular date (the “Valuation Date”) shall mean the following: (a) if the Common Stock is then listed on a national stock exchange, the closing sale price of one share of Common Stock on such
exchange on the last trading day prior to the Valuation Date; (b) if the Common Stock is then quoted on The Nasdaq Stock Market, Inc. (“Nasdaq”), the National Association of Securities Dealers, Inc. OTC Bulletin Board (the
“Bulletin Board”) or such similar exchange or association, the closing sale price of one share of Common Stock on Nasdaq, the Bulletin Board or such other exchange or association on the last trading day prior to the Valuation Date or, if
no such closing sale price is available, the average of the high bid and the low asked price quoted thereon on the last trading day prior to the Valuation Date; or (c) if the Common Stock is not then listed on a 
  

 -4- 

 national stock exchange or quoted on Nasdaq, the Bulletin Board or such other exchange or association, the fair market
value of one share of Common Stock as of the Valuation Date, shall be determined in good faith by the Board of Directors of the Company and the Warrantholder. If the Common Stock is not then listed on a national securities exchange, the Bulletin
Board or such other exchange or association, the Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Warrantholder prior to the exercise hereunder as to the fair market value of a share of Common Stock as
determined by the Board of Directors of the Company. In the event that the Board of Directors of the Company and the Warrantholder are unable to agree upon the fair market value in respect of subpart (c) hereof, the Company and the
Warrantholder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne equally by the Company and the Warrantholder. Such
adjustment shall be made successively whenever such a payment date is fixed. 
 (d) An adjustment to the Warrant Price shall become effective
immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment. 
 (e) In the event that, as a result of an adjustment made pursuant to this Section 8, the Warrantholder shall become entitled to receive any shares of capital stock of the Company other than shares of Common
Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant
Shares contained in this Warrant. 
 Section 9. Fractional Interest. The Company shall not be required to issue fractions of
Warrant Shares upon the exercise of this Warrant. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 9, be deliverable upon such exercise, the Company, in lieu of delivering such
fractional share, shall pay to the exercising Warrantholder an amount in cash equal to the Market Price of such fractional share of Common Stock on the date of exercise. 
 Section 10. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it
being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder. 
 Section 11.
Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company,
stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice
to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment. 
  

 -5- 

 Section 12. Identity of Transfer Agent. The Transfer Agent for the Common Stock is Wells
Fargo Shareholder Services. Upon the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company
will mail to the Warrantholder a statement setting forth the name and address of such transfer agent. 
 Section 13. Notices.
Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given
upon such delivery, (ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, (iii) if given by mail, then such notice shall be deemed given upon the earlier of
(A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an internationally recognized overnight air courier, then such notice shall be
deemed given one business day after delivery to such carrier. All notices shall be addressed as follows: if to the Warrantholder, at its address as set forth in the Company’s books and records and, if to the Company, at the address as follows,
or at such other address as the Warrantholder or the Company may designate by ten days’ advance written notice to the other:

 Section 16. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Warrant shall
be governed by, and construed in accordance with, the internal laws of the State of California, without reference to the choice of law provisions thereof. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably submits to the
exclusive jurisdiction of the courts of the State of California located in Santa Clara County and the United States District Court for the Northern District of California for the purpose of any suit, action, proceeding or judgment relating to or
arising out of this Warrant and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto by the same methods as are specified for the giving of notices under
this Warrant. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. The Company and, by
accepting this Warrant, the Warrantholder, each irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought
in any such court has been brought in an inconvenient forum. EACH OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE WARRANTHOLDER HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS WARRANT AND REPRESENTS
THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 Section 17. Cashless Exercise. Subject to the provisions
hereof, the Warrantholder may exercise this Warrant in whole or in part at any time prior to its expiration upon surrender of the Warrant and elect to receive, without the payment by the Warrantholder of the aggregate Warrant Price in respect of the
shares of Common Stock to be acquired, shares of Common Stock equal to the value of this Warrant or any portion hereof by the surrender of this Warrant (or such portion of this Warrant being so exercised) together with the Net Issue Election Notice
annexed hereto as Appendix B duly executed, at the office of the Company. Thereupon, the Company shall issue to the Warrantholder such number of fully paid, validly issued and nonassessable shares of Common Stock as is computed using the following
formula: 
  

							
		 	 X =
	 	 Y (A - B)
	 	
		 		 	 A
	 	

 where 
 X = the number of shares of Common Stock which the Warrantholder has then requested be issued to the Warrantholder; 
 Y = the
total number of shares of Common Stock covered by this Warrant which the Warrantholder has surrendered at such time for cash-less exercise (including both shares to be issued to the Warrantholder and shares to be canceled as payment therefor);

 A = the “Market Price” of one share of Common Stock as at the time the net issue election is made; and 
  

 -7- 

 B = the Warrant Price in effect under this Warrant at the time the net issue election is made.

 Section 18. No Rights as Stockholder. Prior to the exercise of this Warrant, the Warrantholder shall not have or exercise any
rights as a stockholder of the Company by virtue of its ownership of this Warrant. 
 Section 19. Amendment; Waiver. This Warrant
is one of a series of Warrants of like tenor issued by the Company pursuant to the Purchase Agreement and initially covering an aggregate of 193,453 shares of Common Stock (collectively, the “Company Warrants”). Any term of this
Warrant may be amended or waived (including the adjustment provisions included in Section 8 of this Warrant) upon the written consent of the Company and the holders of Company Warrants representing at least 50% of the number of shares of Common
Stock then subject to all outstanding Company Warrants (the “Majority Holders”); provided, that (x) any such amendment or waiver must apply to all Company Warrants; and (y) the number of Warrant Shares subject to
this Warrant, the Warrant Price and the Expiration Date may not be amended, and the right to exercise this Warrant may not be altered or waived, without the written consent of the Warrantholder. 
 Section 20. Section Headings. The section headings in this Warrant are for the convenience of the Company and the Warrantholder and in no way
alter, modify, amend, limit or restrict the provisions hereof.

 “Prospectus” shall mean the prospectus included in any Registration Statement, as amended or supplemented by any prospectus supplement,

security becoming eligible for sale by the Investors pursuant to Rule 144(k).

commercially reasonable efforts to prepare and file with the SEC one or more Registration Statements on Form S-1 or Form S-3 or use commercially reasonable efforts to amend the Registration Statement filed pursuant to clause (i)
above, if such Registration Statement has not previously been declared effective covering the resale of the Additional Shares, but only to the extent the Additional Shares are not at the time covered by an effective Registration Statement. Such
Registration Statement also shall cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock
dividends or similar transactions with respect to the Additional Shares. The Company shall use its reasonable efforts to obtain from each person who now has piggyback registration rights a waiver of those rights with respect to such Registration
Statement. 
 (b) Expenses. The Company shall pay all of its expenses associated with each registration, including filing and printing
fees, and the fees and expenses of its counsel and auditors, provided however, that the Company shall not pay any fees and expenses of any counsel or advisors to the Investors or brokerage fees and commissions incurred by them.

shall use its best efforts to promptly respond to any comment letters received from the Staff of the SEC and to have the Registration Statement declared effective by no later than one hundred fifty (150) days after the Closing. The Company

disposition of the securities covered thereby. 
 (ii) Subject to Section 3 below, for not more than thirty (30) consecutive days
in each instance, and for not more than a total of not more than sixty (60) days in any twelve (12) month period in the aggregate, commencing on the date on which the Company determines a post-effective amendment to the Registration
Statement is required and the date any such post-effective amendment is declared effective, the Company may suspend the use of any Prospectus (an “Allowed Delay”); provided, that the Company shall promptly (a) notify the
Investors in writing of the existence of (but in no event, without the prior written consent of an Investor, shall the Company disclose to such Investor any of the facts or circumstances regarding) material non-public information giving rise to an
Allowed Delay, (b) advise the Investors in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.
Each Investor hereby covenants that it will not sell any Registrable Securities pursuant to the Prospectus during the existence of an Allowed Delay. 
 3. Company Obligations. The Company will use its best efforts to effect the registration of the Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will, as
expeditiously as possible: 
  

 -3- 

 (a) use its commercially reasonable efforts to cause such Registration Statement to become effective and
to remain continuously effective for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, or (ii) two years
after the Closing (as defined in the Purchase Agreement) (the “Effectiveness Period”); 
 (b) prepare and file with the SEC
such amendments and post-effective amendments to the Registration Statement and the Prospectus as may be necessary to keep the Registration Statement effective for the period specified in Section 3(a) and to comply with the provisions of the
1933 Act and the 1934 Act with respect to the distribution of all of the Registrable Securities covered thereby; 
 (c) furnish to the
Investors such number of copies of a Prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as each Investor may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such Investor that are covered by the related Registration Statement; 
 (d) use commercially reasonable
efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order at the earliest possible moment; 
 (e) prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate with the Investors
and their counsel in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions requested by the Investors and do any and all other commercially
reasonable acts or things necessary or advisable to enable the distribution in such jurisdictions of the Registrable Securities covered by the Registration Statement; provided, however, that the Company shall not be required in connection therewith
or as a condition thereto to (i) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(e), (ii) subject itself to general taxation in any jurisdiction where it would not
otherwise be so subject but for this Section 3(e), or (iii) file a general consent to service of process in any such jurisdiction; 
 (f) immediately notify the Investors, at any time when a Prospectus relating to Registrable Securities is required to be delivered under the 1933 Act, upon discovery that, or upon the happening of any event (without describing such event)
as a result of which, the Prospectus included in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing, and at the request of any such holder, promptly prepare and furnish to such holder a reasonable number of copies of a supplement to or an amendment of such Prospectus as may be
necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus shall not include an 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 light of the circumstances then existing; and 
  

 -4- 

 (g) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of
the SEC under the 1933 Act and the 1934 Act, take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder, and make available to its security holders, as soon as reasonably
practicable, but not later than the Availability Date (as defined below), an earnings statement covering a period of at least twelve (12) months, beginning after the effective date of each Registration Statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the 1933 Act, including Rule 158 promulgated thereunder (for the purpose of this subsection 3(g), “Availability Date” means the 45th day following the end of the fourth
fiscal quarter that includes the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the 90th day after the end
of such fourth fiscal quarter). 
 (h) With a view to making available to the Investors the benefits of Rule 144 (or its successor rule)
and any other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock to the public without registration, the Company covenants and agrees, until the earlier of (A) such date as all of the
Registrable Securities may be resold pursuant to Rule 144(k) or any other rule of similar effect, (B) such date as all of the Registrable Securities shall have been resold, or (C) three years from the Closing (as defined in the
Purchase Agreement): (i) subject to the other qualifications contained in this Agreement, use commercially reasonable efforts to make and keep public information available, as those terms are understood and defined in Rule 144 (ii) to
file with the SEC in a timely manner all reports and other documents required of the Company under the 1934 Act; and (iii) to furnish to each Investor upon request, as long as such Investor owns any Registrable Securities, (A) a written
statement by the Company that it has complied with the reporting requirements of the 1934 Act, (B) a copy of the Company’s most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other
information as may be reasonably requested in order to avail such Investor of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration. 
 4. Obligations of the Investors. 
 (a)
Each Investor has answered all questions on the Investor Questionnaire attached hereto as Exhibit B for use in preparation of the Registration Statement and the answers thereto are true, correct and complete as of the date hereof and will be
true, correct and complete throughout the Effectiveness Period and each Investor will notify the Company immediately of any change in any of such information until the end of the Effectiveness Period. 
 (b) Each Investor, by its acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in
connection with the preparation and filing of a Registration Statement hereunder, unless such Investor has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement. 
 (c) Each Investor agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to
Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(f) hereof, such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable
Securities, 
  

 -5- 

 until the Investor’s receipt of the copies of the supplemented or amended prospectus filed with the SEC and until
any related post-effective amendment is declared effective and, if so directed by the Company, the Investor shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies
in the Investor’s possession of the Prospectus covering the Registrable Securities current at the time of receipt of such notice. 
 5.
Indemnification. 
 (a) Indemnification by the Company. The Company will, notwithstanding any termination of this Agreement,
indemnify and hold harmless each Investor and its officers, directors, members, employees and agents, successors and assigns, and each other person, if any, who controls such Investor within the meaning of the 1933 Act, against any third party
losses, claims, damages or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon:
(i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof; (ii) any blue sky
application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities
under the securities laws thereof (any such application, document or information herein called a “Blue Sky Application”); (iii) the omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; (iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction
required of the Company in connection with such registration; or (v) any failure to register or qualify the Registrable Securities included in any such Registration in any state where the Company or its agents has affirmatively undertaken or
agreed in writing that the Company will undertake such registration or qualification on an Investor’s behalf and will reimburse such Investor, and each such officer, director or member and each such controlling 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; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Investor or any such controlling person in writing
specifically for use in such Registration Statement or Prospectus. 
 (b) Indemnification by the Investors. Each Investor agrees,
severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against
any third party losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or
Prospectus or preliminary prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in any information
furnished in writing by such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. For the 
  

 -6- 

 purposes of this Section, the information contained in Exhibit A and Exhibit B hereto shall be
deemed to have been furnished by the Investors to the Company specifically for inclusion in the Registration Statement, the Prospectus and any amendment or supplement thereto. In no event shall the liability of an Investor be greater in amount than
the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 5 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue
statement or omission) received by such Investor upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation. 
 (c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying
party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has
agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based
upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ
separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give notice
as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation.
It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No
indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim or litigation. 
 (d) Contribution. If for any reason the
indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the
amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other
relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no
event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 5 and the
amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution
obligation. 
  

 -7- 

 6. Miscellaneous. 
 (a) Piggyback on Registrations. If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to
prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the 1933 Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the
1933 Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, then
the Company shall send to each Investor written notice of such determination and, if within fifteen days after receipt of such notice, any such Investor shall so request in writing, the Company shall include in such registration statement all or any
part of such Registrable Securities such holder requests to be registered, subject to customary underwriter cutbacks applicable to all holders of registration rights. 
 (b) Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the Required Investors. The Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, only if the Company shall have obtained the written consent to such amendment, action or omission to act, of the Required Investors. 
 (c) Notices. All notices and other communications provided for or permitted hereunder shall be made as set forth in Section 9.4 of the Purchase Agreement. 
 (d) Assignments and Transfers by Investors. The provisions of this Agreement shall be binding upon and inure to the benefit of the Investors and
their respective successors and assigns. An Investor may transfer or assign, in whole or from time to time in part, to one or more persons its rights hereunder in connection with the transfer of Registrable Securities by such Investor to such
person, provided that such Investor complies with all laws applicable thereto and provides written notice of assignment to the Company promptly after such assignment is effected. 
 (e) Assignments and Transfers by the Company. This Agreement may not be assigned by the Company (whether by operation of law or otherwise) without
the prior written consent of the Required Investors, provided, however, that the Company may assign its rights and delegate its duties hereunder to any surviving or successor corporation in connection with a merger or consolidation of the Company
with another corporation, or a sale, transfer or other disposition of all or substantially all of the Company’s assets to another corporation, without the prior written consent of the Required Investors, after notice duly given by the Company
to each Investor. 
 (f) Benefits of the Agreement. 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. 
  

 -8-

hereof be construed in favor of the classification of the Warrants as equity under EITF No. 00-19. 
 (h) Counterparts; Faxes.
This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may also be executed via facsimile, which shall be deemed

 (i) Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to
be considered in construing or interpreting this Agreement. 
 (j) Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be
enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by
applicable law, the parties hereby waive any provision of law which renders any provisions hereof prohibited or unenforceable in any respect. 
 (k) Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence

jurisdiction of the courts of the State of California located in Santa Clara County and the United States District Court for the Northern District of California for the purpose of any suit, action, proceeding or judgment relating to or arising out
of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto by the same methods as are specified for the giving of notices under this
Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of
venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES

 EXHIBIT A 
 Plan of Distribution 
 The selling stockholders, which as used herein includes donees, pledgees,
transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer,
may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private
transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. 
 The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein: 
 - ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 
 - block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to
facilitate the transaction; 
 - purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 
 - an exchange distribution in accordance with the rules of the applicable exchange; 
 - privately negotiated transactions; 
 -
short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the SEC; 
 -
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; 
 -
broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; and 
 - a
combination of any such methods of sale. 
 The selling stockholders may, from time to time, pledge or grant a security interest in some or
all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under
an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders

 under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in
which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. 
 In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common
stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers
that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to
such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

 The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the
common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made
directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of the warrants. 
 The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities
Act of 1933, provided that they meet the criteria and conform to the requirements of that rule. 
 The selling stockholders and any
underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or
profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject
to the prospectus delivery requirements of the Securities Act. 
 To the extent required, the shares of our common stock to be sold, the
names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an
accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus. 
 In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be
sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with. 
  

 -2- 

 We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the
Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to
the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against
certain liabilities, including liabilities arising under the Securities Act. 
 We have agreed to indemnify the selling stockholders against
liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus. 
 We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this
prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the Securities Act.
