 Void After 5 P.M. Eastern Time on December 31, 2020 
 THIS CERTIFIES THAT, for value received, Carilion Clinic, formerly known as Carilion Health System, or assigns, with its

$0.001, of the Company (the “Common Stock”) determined in accordance with the terms of this Warrant and the attachments hereto (the “Warrant”). 
 1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings: 
 (a) “Exercise Period” shall mean the period commencing at 5:00 P.M. Eastern Time on December 31, 2012
and continuing for eight (8) years thereafter. 
 (b) “Exercise Price” shall mean $2.50 per
share, subject to adjustment pursuant to Section 5 below. 
 (c) “Exercise Shares” shall
mean the 10,000 shares of Common Stock issuable upon exercise of this Warrant, subject to adjustment pursuant to the terms herein, including but not limited to adjustment pursuant to Section 5 below. 
 2. EXERCISE OF WARRANT. 
 2.1 Procedure. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address
set forth above (or at such other address as it may designate by notice in writing to the Holder): 
 (a) An executed
Notice of Exercise in the form attached hereto (the “Notice of Exercise”); 

 (b) Payment of the Exercise Price either (i) in cash, by wire transfer or by
check, (ii) by cancellation of indebtedness, or (iii) by net exercise in accordance with Section 2.2 hereof; and 
 (c) This Warrant. 
 Upon the exercise of the rights represented by this Warrant, a certificate or certificates
for the Exercise Shares so purchased, in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant
shall have been so exercised, and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired shall be issued and delivered to the Holder within a reasonable time after the
rights represented by this Warrant shall have been so exercised. 
 The person in whose name any certificate or certificates for
the Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the
date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at
the close of business on the next succeeding date on which the stock transfer books are open. 
 2.2 Net Exercise.
Notwithstanding any provisions herein to the contrary, if the fair market value of one share of the Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of
cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly completed
and endorsed Notice of Exercise, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula: 
  

							
		 	X	  	=	  	Y (A-B)
		 		  		  	     A
				
	Where	 	X	  	=	  	the number of shares of Common Stock to be issued to the Holder
				
		 	Y	  	=	  	the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of
such calculation)

  

 2 

							
		 	A	  	=	  	the fair market value of one share of the Common Stock (at the date of such calculation)
				
		 	B	  	=	  	Exercise Price (as adjusted to the date of such calculation)

 For purposes of the above calculation, the fair market value of one share of Common
Stock shall mean the average of the closing bid and asked prices of Common Stock quoted in the over-the-counter market in which the Common Stock is traded or the closing price quoted on any exchange on which the Common Stock is listed, whichever is
applicable, as published in the Eastern Edition of The Wall Street Journal for the ten (10) trading days prior to the date on which this Warrant is surrendered and payment of the Exercise Price has been paid (or such shorter period of
time during which such stock was traded over-the-counter or on such exchange). If the Common Stock is not traded on the over-the-counter market or on an exchange, the fair market value shall be the price per share that the Company could obtain from
a willing buyer for Common Stock sold by the Company from authorized but unissued shares, as such price shall be determined in good faith by the Company’s Board of Directors. 
 3. COVENANTS OF THE COMPANY. The Company covenants and agrees that all the Exercise Shares that may be issued upon the exercise of
the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable. The Company further covenants and agrees that the Company will at all times during the Exercise Period have authorized and
reserved a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. 
 4. REPRESENTATIONS OF HOLDER. 
 4.1 Acquisition of Warrant for Personal Account. The Holder represents
and warrants that it is acquiring the Warrant and the Exercise Shares solely for its account for investment and not with a view to or for sale or distribution of said Warrant or the Exercise Shares or any part thereof. The Holder also represents
that the entire legal and beneficial interests of the Warrant and the Exercise Shares the Holder is acquiring is being acquired for, and will be held for, its account only. 
 4.2 Securities Are Not Registered. 
 (a) The Holder understands that the Warrant and the Exercise Shares have not been registered under the Securities Act of 1933, as amended (the “Act”) on the basis that no
distribution or public offering of the stock of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the
securities for a fixed or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention. 
 (b) The Holder recognizes that the Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered
under the Act or an exemption from such registration is available. The Holder recognizes that the Company has no obligation to register the Warrant or the Exercise Shares of the Company, or to comply with any exemption from such registration.

  

 3 

 (c) The Holder is aware that neither the Warrant nor the Exercise Shares may be sold
pursuant to Rule 144 adopted under the Act unless certain conditions are met, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale
following the required holding period under Rule 144 and the number of shares being sold during any three month period not exceeding specified limitations. 
 4.3 Disposition of Warrant and Exercise Shares. 
 (a) The Holder
further agrees not to make any disposition of all or any part of the Warrant or the Exercise Shares in any event unless and until: 
 (i) There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with said registration statement; 
 (ii) The Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the
effect that such disposition will not require registration of such Warrant or the Exercise Shares under the Act or any applicable state securities laws; or 
 (iii) The Company shall have received a letter secured by the Holder from the Securities and Exchange Commission stating that no action will be recommended to the Commission with respect to the
proposed disposition. 
 (b) The Holder understands and agrees that all certificates evidencing the shares to be issued
to the Holder may bear the following legend: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE AMENDED AND RESTATED INVESTOR
RIGHTS AGREEMENT, THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE
OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A

  

 4 

 
BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT
OR OTHER LOAN SECURED BY SUCH SECURITIES. 
 5. ADJUSTMENT OF EXERCISE SHARES AND EXERCISE PRICE. 
 (a) Stock Splits, Combinations, etc. In the event of changes in the outstanding Common Stock of the Company by reason of stock
dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and the Exercise
Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had the Warrant been exercised prior to the
event and had the Holder continued to hold such shares until after the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number of the Exercise Shares subject to this Warrant. The foregoing
provisions of this Section 5(a) shall similarly apply to successive stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like and to the stock
or securities of any other entity that are at the time receivable upon the exercise of this Warrant. 
 (b) Merger, Sale of
Assets, etc. If at any time while this Warrant, or any portion hereof, is outstanding and unexpired there shall occur (i) the sale, conveyance, exchange, license or other transfer of all or substantially all of the intellectual property or
assets of the Company, (ii) any acquisition of the Company by means of a consolidation, stock exchange, merger or other form of corporate reorganization of the Company with any other corporation in which the Company’s stockholders prior to
the consolidation or merger own less than a majority of the voting securities of the surviving entity or (iii) any transaction or series of related transactions following which the Company’s stockholders prior to such transaction or series
of related transactions own less than a majority of the voting securities of the Company (collectively, a “Change of Control”), this Warrant shall cease to represent the right to receive the Exercise Shares and shall
automatically and without further action represent the right to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect, the number of shares of stock or other securities or
property offered to the Company’s holders of Common Stock in connection with such Change of Control that a holder of the shares deliverable upon exercise of this Warrant would have been entitled to receive in such Change of Control if this
Warrant had been exercised immediately before such Change of Control, subject to further adjustment as provided in this Section 5. The foregoing provisions of this Section 5(b) shall similarly apply to successive reorganizations,
consolidations, mergers, sales and transfers and to the stock or securities of any other entity that are at the time receivable upon the exercise of this Warrant. If the per share consideration payable to the holder hereof in connection with any
such transaction is in a form other than cash or marketable securities, then the value of such consideration shall be determined in good faith by the Company’s Board of Directors. In all events, appropriate adjustment (as determined in good
faith by the Company’s Board of Directors) shall be made in the application of the provisions of

  

 5 

 
this Warrant with respect to the rights and interests of the Holder after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as
reasonably may be, in relation to any shares or other property deliverable after that event upon exercise of this Warrant. 
 6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be
aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any
fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction. 
 7. NOTICE OF CERTAIN EVENTS. The Company shall provide to the Holder at least five (5) days advance written notice of any event
that would result in an adjustment to the Exercise Shares or Exercise Price pursuant to Section 5 hereof. 
 8. MARKET
STAND-OFF AGREEMENT. In connection with any public offering of securities of the Company registered under the Act, the Holder hereby agrees not to sell, transfer, make any short sale of, grant any option for the purchase of, enter into any
hedging or similar transaction with the same economic effect as a sale or otherwise transfer or dispose of any Common Stock (or any other securities of the Company) held by the Holder (other than those included in the registration) for a period of
one hundred eighty (180) calendar days following the effective date of a registration statement of the Company filed under the Act in connection with such offering (or such other period as may be requested by the Company or an underwriter to
accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE
Rule 472(f)(4), or any successor provisions or amendments thereto). The Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s
obligations under this Section 8 or that are necessary to give further effect thereto. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or any other securities) subject to the foregoing restriction
until the end of the market stand-off day period. 
 9. NO STOCKHOLDER RIGHTS. This Warrant in and of itself shall not
entitle the Holder to any voting rights or other rights as a stockholder of the Company. 
 10. TRANSFER OF WARRANT.
Subject to applicable laws and the restriction on transfer set forth on the first page of this Warrant, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and
the form of assignment attached hereto to any transferee designated by the Holder. The transferee shall sign an investment letter in form and substance satisfactory to the Company. 
 11. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such
terms as to indemnity

  

 6 

 
or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so
lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

 12. NOTICES, ETC. Any notices required or permitted hereunder shall be in writing and shall be deemed effectively
given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five (5) days after
having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of
receipt. All communications shall be sent to the Company or to the Holder at their respective addresses set forth above or at such other address as the Company or the Holder may designate by ten (10) days advance written notice to the other
parties hereto. 
 13. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to
all of the terms and conditions contained herein.

liabilities hereunder shall be governed by the laws of the State of Delaware.

$0.001, of the Company (the “Common Stock”) determined in accordance with the terms of this Warrant and the attachments hereto (the “Warrant”). 
 1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings: 
 (a) “Exercise Period” shall mean the period commencing at 5:00 P.M. Eastern Time on February 1, 2013 and

 (c) “Exercise Shares” shall mean the 356,000
shares of Common Stock issuable upon exercise of this Warrant, subject to adjustment pursuant to the terms herein, including but not limited to adjustment pursuant to Section 5 below. 
 2. EXERCISE OF WARRANT. 
 2.1 Procedure. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address
set forth above (or at such other address as it may designate by notice in writing to the Holder): 
 (a) An executed
Notice of Exercise in the form attached hereto (the “Notice of Exercise”); 

 (b) Payment of the Exercise Price either (i) in cash, by wire transfer or by
check, (ii) by cancellation of indebtedness, or (iii) by net exercise in accordance with Section 2.2 hereof; and 
 (c) This Warrant. 
 Upon the exercise of the rights represented by this Warrant, a certificate or certificates
for the Exercise Shares so purchased, in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant
shall have been so exercised, and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired shall be issued and delivered to the Holder within a reasonable time after the

 The person in whose name any certificate or certificates for

date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at
the close of business on the next succeeding date on which the stock transfer books are open. 
 2.2 Net Exercise.
Notwithstanding any provisions herein to the contrary, if the fair market value of one share of the Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of
cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly completed
and endorsed Notice of Exercise, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula: 
  

					
	X	 	=	 	Y (A-B)
		 		 	     A
			
	Where X	 	=	 	the number of shares of Common Stock to be issued to the Holder
			
	Y	 	=	 	the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date
of such calculation)

  

 2

Stock shall mean the average of the closing bid and asked prices of Common Stock quoted in the over-the-counter market in which the Common Stock is traded or the closing price quoted on any exchange on which the Common Stock is listed, whichever is

time during which such stock was traded over-the-counter or on such exchange). If the Common Stock is not traded on the over-the-counter market or on an exchange, the fair market value shall be the price per share that the Company could obtain from
a willing buyer for Common Stock sold by the Company from authorized but unissued shares, as such price shall be determined in good faith by the Company’s Board of Directors. 
 3. COVENANTS OF THE COMPANY. The Company covenants and agrees that all the Exercise Shares that may be issued upon the exercise of
the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable. The Company further covenants and agrees that the Company will at all times during the Exercise Period have authorized and
reserved a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. 
 4. REPRESENTATIONS OF HOLDER. 
 4.1 Acquisition of Warrant for Personal Account. The Holder represents
and warrants that it is acquiring the Warrant and the Exercise Shares solely for its account for investment and not with a view to or for sale or distribution of said Warrant or the Exercise Shares or any part thereof. The Holder also represents

 4.2 Securities Are Not Registered. 
 (a) The Holder understands that the Warrant and the Exercise Shares have not been registered under the Securities Act of 1933, as amended (the “Act”) on the basis that no
distribution or public offering of the stock of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the
securities for a fixed or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention. 
 (b) The Holder recognizes that the Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered

 3 

 (c) The Holder is aware that neither the Warrant nor the Exercise Shares may be sold
pursuant to Rule 144 adopted under the Act unless certain conditions are met, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale
following the required holding period under Rule 144 and the number of shares being sold during any three month period not exceeding specified limitations. 
 4.3 Disposition of Warrant and Exercise Shares. 
 (a) The Holder
further agrees not to make any disposition of all or any part of the Warrant or the Exercise Shares in any event unless and until:

 (ii) The Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the
effect that such disposition will not require registration of such Warrant or the Exercise Shares under the Act or any applicable state securities laws; or 
 (iii) The Company shall have received a letter secured by the Holder from the Securities and Exchange Commission stating that no action will be recommended to the Commission with respect to the
proposed disposition. 
 (b) The Holder understands and agrees that all certificates evidencing the shares to be issued
to the Holder may bear the following legend: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE AMENDED AND RESTATED INVESTOR
RIGHTS AGREEMENT, THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE
OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A

  

 4 

 
BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT
OR OTHER LOAN SECURED BY SUCH SECURITIES. 
 5. ADJUSTMENT OF EXERCISE SHARES AND EXERCISE PRICE. 
 (a) Stock Splits, Combinations, etc. In the event of changes in the outstanding Common Stock of the Company by reason of stock
dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and the Exercise
Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had the Warrant been exercised prior to the
event and had the Holder continued to hold such shares until after the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number of the Exercise Shares subject to this Warrant. The foregoing
provisions of this Section 5(a) shall similarly apply to successive stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like and to the stock
or securities of any other entity that are at the time receivable upon the exercise of this Warrant. 
 (b) Merger, Sale of
Assets, etc. If at any time while this Warrant, or any portion hereof, is outstanding and unexpired there shall occur (i) the sale, conveyance, exchange, license or other transfer of all or substantially all of the intellectual property or
assets of the Company, (ii) any acquisition of the Company by means of a consolidation, stock exchange, merger or other form of corporate reorganization of the Company with any other corporation in which the Company’s stockholders prior to
the consolidation or merger own less than a majority of the voting securities of the surviving entity or (iii) any transaction or series of related transactions following which the Company’s stockholders prior to such transaction or series
of related transactions own less than a majority of the voting securities of the Company (collectively, a “Change of Control”), this Warrant shall cease to represent the right to receive the Exercise Shares and shall
automatically and without further action represent the right to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect, the number of shares of stock or other securities or
property offered to the Company’s holders of Common Stock in connection with such Change of Control that a holder of the shares deliverable upon exercise of this Warrant would have been entitled to receive in such Change of Control if this
Warrant had been exercised immediately before such Change of Control, subject to further adjustment as provided in this Section 5. The foregoing provisions of this Section 5(b) shall similarly apply to successive reorganizations,
consolidations, mergers, sales and transfers and to the stock or securities of any other entity that are at the time receivable upon the exercise of this Warrant. If the per share consideration payable to the holder hereof in connection with any
such transaction is in a form other than cash or marketable securities, then the value of such consideration shall be determined in good faith by the Company’s Board of Directors. In all events, appropriate adjustment (as determined in good
faith by the Company’s Board of Directors) shall be made in the application of the provisions of

  

 5 

 
this Warrant with respect to the rights and interests of the Holder after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as
reasonably may be, in relation to any shares or other property deliverable after that event upon exercise of this Warrant. 
 6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be
aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any
fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction. 
 7. NOTICE OF CERTAIN EVENTS. The Company shall provide to the Holder at least five (5) days advance written notice of any event
that would result in an adjustment to the Exercise Shares or Exercise Price pursuant to Section 5 hereof. 
 8. MARKET
STAND-OFF AGREEMENT. In connection with any public offering of securities of the Company registered under the Act, the Holder hereby agrees not to sell, transfer, make any short sale of, grant any option for the purchase of, enter into any
hedging or similar transaction with the same economic effect as a sale or otherwise transfer or dispose of any Common Stock (or any other securities of the Company) held by the Holder (other than those included in the registration) for a period of
one hundred eighty (180) calendar days following the effective date of a registration statement of the Company filed under the Act in connection with such offering (or such other period as may be requested by the Company or an underwriter to
accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE
Rule 472(f)(4), or any successor provisions or amendments thereto). The Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s
obligations under this Section 8 or that are necessary to give further effect thereto. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or any other securities) subject to the foregoing restriction
until the end of the market stand-off day period. 
 9. NO STOCKHOLDER RIGHTS. This Warrant in and of itself shall not
entitle the Holder to any voting rights or other rights as a stockholder of the Company. 
 10. TRANSFER OF WARRANT.
Subject to applicable laws and the restriction on transfer set forth on the first page of this Warrant, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and
the form of assignment attached hereto to any transferee designated by the Holder. The transferee shall sign an investment letter in form and substance satisfactory to the Company and shall be subject to all terms and conditions of this Warrant.

 11. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen,
mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as
the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable
by anyone. 
 12. NOTICES, ETC. Any notices required or permitted hereunder shall be in writing and shall be deemed
effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five
(5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written
verification of receipt. All communications shall be sent to the Company or to the Holder at their respective addresses set forth above or at such other address as the Company or the Holder may designate by ten (10) days advance written notice
to the other parties hereto. 
 13. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and
agreement to all of the terms and conditions contained herein. 
 14. GOVERNING LAW. This Warrant and all rights,
obligations and liabilities hereunder shall be governed by the laws of the State of Delaware. 
 15. AMENDMENT. Any term
of this Warrant may be amended or waived with the written consent of the Company and Holder.

 IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by its duly authorized officer as of January 13, 2010.

required.
