Warrant, LEADER EQUITY, LLC and its assignees are entitled to subscribe for and purchase 317,633 shares of Series E Preferred Stock (except as otherwise provided below) of VOCERA COMMUNICATIONS, INC., a Delaware corporation (the
“Company”), at the price of $1.1019 per share (such price and such other price as shall result, from time to time, from the adjustments specified in 5 hereof is referred to as the “Warrant
Price”). 
 1. Definitions. As used herein, capitalized terms not otherwise defined herein
shall have the following respective meanings: 
 (a) “Acquisition” means
any sale or other disposition of all or substantially all of the assets (including intellectual property) of the Company, or any reorganization, consolidation, or merger of the Company where the holders of the Company’s securities before the
transaction beneficially own, for or in consideration of their preexisting equity ownership in the Company, less than 50% of the outstanding voting securities of the entity that succeeds to the business of the Company after the transaction.

 (b) “Act” means the Securities Act of 1933, as amended; 

(c) “Common Stock” means the Common Stock of the Company; 

(d) “Date of Grant” means October 17, 2005;

paragraph of this Warrant and any other person or entity which becomes a holder of this Warrant pursuant to the terms of this Warrant; 
 (f) “IPO” means the initial public offering of the Company’s Common Stock effected pursuant to a registration statement on Form S-1 (or its successor) filed under the Act;

  

 (g) “Other Warrants” means any other
warrants issued by the Company in connection with the transaction with respect to which this Warrant was issued, and any warrant issued upon transfer or partial exercise of or in lieu of this Warrant. The term “Warrant” as used herein
shall be deemed to include Other Warrants unless the context clearly requires otherwise; 
 (h)
“Series Preferred” means (i) the Company’s presently authorized Series E Preferred Stock, (ii) after the conversion of all of the outstanding shares of Series E Preferred Stock into Common Stock,
either automatically or by vote of the requisite holders thereof, the Company’s Common Stock, (iii) upon any conversion, exchange, reclassification or change, any security into which the securities described in clauses (i) or
(ii) of this definition may be converted, exchanged, reclassified or otherwise changed; (iv) if Pay to Play Provisions are applied to the Series Preferred, the security that a holder of Series Preferred would have received had
such holder participated in the manner necessary to receive or retain the security having the rights more favorable to the holder. “Pay to Play Provisions” means (i) provisions that require the holder of a security to participate in a
subsequent round of equity financing or lose all or a portion of the benefit of antidilution protection applicable to a security or have such security automatically convert to common stock or another series of capital stock, or (ii) an exchange

 (i) “Shares”
means the shares of Series Preferred of Company issuable upon exercise of this Warrant. 
 2.
Term. The purchase right represented by this Warrant is exercisable, in whole or in part, at any time and from time to time from the Date of Grant through the earlier of (i) the tenth anniversary of the Date of Grant or (ii) the
first anniversary of the closing of the Company’s IPO. 
 Notwithstanding the foregoing: 

(i) in the event of an Acquisition where the consideration to be received by holders of Series Preferred upon such
Acquisition is all cash (including any deferred payment of cash), then this Warrant (A) to the extent the cash consideration per share of Series Preferred that is payable at the closing of the Acquisition exceeds the Warrant Price, shall
be deemed exercised in accordance with the provisions of Section 3(b) immediately prior to the closing of the Corporate Event, or (B) to the extent the cash consideration per share of Series Preferred payable at the closing of the
Acquisition does not exceed the Warrant Price, shall terminate; and 
 (ii) in the event of an Acquisition where
(A) the consideration paid per share of Series referred upon such Acquisition is to be in excess of the Warrant Price effective at the time of the Acquisition, (B) the consideration to be received by holders of Series Preferred in
such Acquisition is cash (including deferred payment of cash) and/or shares of a publicly traded company listed on a national market or exchange, that are freely tradable without restrictions, except for those of Rule 144 or 145 promulgated under
the Act, and (C) no other warrants or options (other than options issued to employees, officers, directors, independent contractors or consultants) will be assumed by the acquiring entity (or its parent) in connection with the Acquisition, then
this Warrant shall be deemed exercised in accordance with the provisions of Section 3(b) immediately prior to the closing of the Acquisition; 

  

 
provided, that, in either case, the Holder shall have the option to exercise this Warrant for cash immediately prior to the closing of the Acquisition. 

In the event of an Acquisition, that satisfies the conditions set forth in clause (ii) of the previous paragraph,
other than the condition set forth in clause (A) thereof, the Company shall have the option to purchase this Warrant upon the closing of the Acquisition from the Holder at a purchase price equal to the value of the Warrant as determined by
application of the Black-Scholes formula. If the Company and the Holder are unable to agree upon the appropriate calculation using such a formula, then they will reasonably cooperate to engage an investment banker to determine such calculation, with
the costs of such investment banker shared equally by the Company and the Holder. 
 3. Method of Exercise;
Payment; Issuance of New Warrant; Net Issuance. 
 (a) Subject to Section 1 hereof, the
purchase right represented by this Warrant may be exercised by the Holder, in whole or in part and from time to time, at the election of the Holder, by (a) the surrender of this Warrant (with the notice of exercise substantially in the form
attached hereto as Exhibit A-1 duly completed and executed) at the principal office of the Company and by the payment to the Company, by certified or bank check, or by wire transfer to an account designated by the Company (a “Wire
Transfer”) of an amount equal to the then applicable Warrant Price multiplied by the number of Shares then being purchased; (b) if in connection with a registered public offering of the Company’s securities, the surrender of this
Warrant (with the notice of exercise form attached hereto as Exhibit A-2 duly completed and executed) at the principal office of the Company together with notice of arrangements reasonably satisfactory to the Company for payment to the Company
from the proceeds of the sale of shares to be sold by the Holder in such public offering of an amount equal to the then applicable Warrant Price per share multiplied by the number of Shares then being purchased; or (c) exercise of the “net
issuance” right provided for in Section 3(b) hereof. The person or persons in whose name(s) Shares shall be registered upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all
purposes as the record holder(s) of, the shares represented thereby (and such shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised. In the event of any
exercise of this Warrant, certificates for the shares of stock so purchased shall be delivered to the Holder promptly and in any event within thirty (30) days after such exercise and, unless this Warrant has been fully exercised or expired, a
new Warrant representing the portion of the Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder promptly and in any event within such thirty-day period; provided, however, that at
such time as the Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, if requested by the Holder, the Company shall cause its transfer agent to deliver the certificate representing Shares issued upon
exercise of this Warrant to, or credit the securities account of, a broker or other person (as directed by the Holder exercising this Warrant) within the time period required to settle any trade made by the Holder after exercise of this Warrant.

  

 (b) Right to Convert Warrant into Stock: Net
Issuance. 
 (i) Right to Convert. In addition to and without limiting the
rights of the Holder under the terms of this Warrant, the Holder shall have the right to convert this Warrant or any portion thereof (the “Conversion Right”) into shares of Series Preferred as provided in this
Section 3(b) at any time or from time to time during the term of this Warrant. Upon exercise of the Conversion Right with respect to a particular number of shares subject to this Warrant (the “Converted Warrant Shares”),
the Company shall deliver to the Holder (without payment by the Holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Series Preferred as is determined according to the
following formula: 
  

							
		 	 X =  
	  	B– A	  	
	 	  	Y	  	

 Where: 
  

					
		 	 X=
	  	 the number of shares to be issued to the holder

			
		 	 Y =
	  	 the fair market value of one share of Series Preferred

			
		 	 A =
	  	 the aggregate Warrant Price of the specified number of Converted Warrant Shares immediately prior to the exercise of the Conversion Right (i.e., the
number of Converted Warrant Shares multiplied by the Warrant Price)

			
		 	 B =
	  	 the aggregate fair market value of the specified number of Converted Warrant Shares (i.e., the number of Converted Warrant Shares multiplied by
the fair market value of one Converted Warrant Share)

 (ii) Method of Exercise. The Conversion Right may be exercised by
the Holder by the surrender of this Warrant at the principal office of the Company together with a written statement (which may be in the form of Exhibit A-1 or Exhibit A-2 hereto) specifying that the Holder thereby intends to exercise the
Conversion Right and indicating the number of shares subject to this Warrant which are being surrendered (referred to in Section 3(b)(i) hereof as the Converted Warrant Shares) in exercise of the Conversion Right. Such conversion shall be
effective upon receipt by the Company of this Warrant together with the aforesaid written statement, or on such later date as is specified therein (the “Conversion Date”), and, at the election of the Holder, may be made
contingent upon the closing of the sale of the Company’s Common Stock to the public in a public offering pursuant to a registration statement under the Act (a “Public Offering”). 

(iii) Determination of Fair Market Value. For purposes of this Section 3(b), “fair market
value” of a share of Series Preferred as of a particular date (the “Determination Date”) shall mean: 

  

 (1) If the Conversion Right is exercised in connection with
and contingent upon a Public Offering, and if the Company’s Registration Statement relating to such Public Offering (“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then
the initial “Price to Public” specified in the final prospectus with respect to such offering. 
 (2) If the Conversion Right is not exercised in connection with and contingent upon a Public Offering, then as follows: 

(A) If traded on a securities exchange, the fair market value of the Common Stock shall be deemed to be
the average of the closing prices of the Common Stock on such exchange over the five trading days immediately prior to the Determination Date, and the fair market value of the Series Preferred shall be deemed to be such fair market value of the
Common Stock multiplied (if Series Preferred is not then constituted as Common Stock) by the number of shares of Common Stock into which each share of Series Preferred is then convertible; 

(B) If traded on the Nasdaq Stock Market or other over-the-counter system, the fair market value of the
Common Stock shall be deemed to be the average of the closing bid prices of the Common Stock over the five trading days immediately prior to the Determination Date, and the fair market value of the Series Preferred shall be deemed to be such
fair market value of the Common Stock multiplied (if Series Preferred is not then constituted as Common Stock) by the number of shares of Common Stock into which each share of Series Preferred is then convertible; and 

(C) If there is no public market for the Common Stock, then fair market value shall be reasonably
determined in good faith by the board of directors of the Company. 
 (iv) In making a
determination under clauses (A) or (B) above, if on the Determination Date, five trading days had not passed since the IPO, then the fair market value of the Common Stock shall be the average closing prices or closing bid prices, as
applicable, for the shorter period beginning on and including the date of the IPO and ending on the trading day prior to the Determination Date (or if such period includes only one trading day the closing price or closing bid price, as applicable,
for such trading day). If closing prices or closing bid prices are no longer reported by a securities exchange or other trading system, the closing price or closing bid price shall be that which is reported by such securities exchange or other
trading system at 4:00 p.m. New York City time on the applicable trading day. 
 4. Stock Fully Paid;
Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all preemptive
rights and liens and charges created by or through the Company with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for
the purpose of the issue upon exercise of the 

  

 
purchase rights evidenced by this Warrant, a sufficient number of shares of its Series Preferred to provide for the exercise of the rights represented by this Warrant and, while applicable,
a sufficient number of shares of its Common Stock to provide for the conversion of the Series Preferred into Common Stock. 
 5. Adjustment of Warrant Price and Number of Shares. The number and kind of securities purchasable upon the exercise of this Warrant and the Warrant Price shall be subject to adjustment from time
to time upon the occurrence of certain events, as follows: 
 (a) Corporate Events. In
case of any reclassification or change of securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or
combination), or in case of any merger of the Company with or into another corporation (other than a merger with another corporation in which the Company is the acquiring and the surviving corporation and which does not result in any
reclassification or change of outstanding securities issuable upon exercise of this Warrant) (each, a “Corporate Event”), the Company, or such successor corporation, as the case may be, shall duly execute and deliver to the
Holder a new Warrant (in form and substance satisfactory to the Holder), or the Company shall make appropriate provision without the issuance of a new Warrant, so that the Holder shall have the right to receive upon exercise of this Warrant, at a
total purchase price not to exceed that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the shares of Series Preferred theretofore issuable upon exercise of this Warrant, the kind and amount of shares of
stock, other securities, money and property receivable upon such Corporate Event by a holder of the number of shares of Series Preferred then purchasable under this Warrant. Any new Warrant shall provide for adjustments that shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Section 5. The provisions of this Section 5(a) shall similarly apply to successive Corporate Events. Notwithstanding the above, a Corporate Event shall not include,
and this Section 5(a) shall not apply to, an Acquisition described in the second paragraph of Section 2. 
 (b) Subdivision or Combination of Shares. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Series Preferred,
the Warrant Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision and the Warrant Price shall be proportionately increased and the number of Shares
issuable hereunder shall be proportionately decreased in the case of a combination. 
 (c)
Stock Dividends and Other Distributions. If the Company at any time while this Warrant is outstanding and unexpired shall (i) pay a dividend with respect to Series Preferred payable in Series Preferred, then the Warrant Price
shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the Warrant Price in effect immediately prior to such date of determination by a
fraction (A) the numerator of which shall be the total number of shares of Series Preferred outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of
Series Preferred outstanding immediately after such dividend or distribution; or (ii) make any other distribution with respect 

  

 
to Series Preferred (except any distribution specifically provided for in Sections 5(a) and 5(b)), then, in each such case, provision shall be made by the Company such that the Holder shall
receive upon exercise of this Warrant a proportionate share of any such dividend or distribution as though it were the holder of the Series Preferred (or Common Stock issuable upon conversion thereof) as of the record date fixed for the
determination of the shareholders of the Company entitled to receive such dividend or distribution. 
 (d) Adjustment of Number of Shares. Upon each adjustment in the Warrant Price, the number of Shares of Series Preferred purchasable hereunder shall be adjusted, to the nearest whole share, to
the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator
of which shall be the Warrant Price immediately thereafter. 
 (e) Antidilution Rights.
The other antidilution rights applicable to the Shares of Series Preferred purchasable hereunder are set forth in the Company’s Certificate of Incorporation, as amended from time to time, a true and complete copy of which, as of the date
hereof, is attached hereto as Exhibit B (the “Charter”). The Company shall promptly provide the Holder with any restatement, amendment, modification or waiver of the Charter promptly after the same has been made. 

6. Notice of Adjustments. Whenever the Warrant Price or the number of Shares purchasable hereunder shall be
adjusted pursuant to Section 5 hereof, the Company shall deliver to Holder a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated, and the Warrant Price and the number of Shares purchasable hereunder after giving effect to such adjustment. In addition, whenever the conversion price or conversion ratio of the Series Preferred shall be
adjusted, the Company shall deliver to Holder a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was
calculated, and the conversion price or ratio of the Series Preferred after giving effect to such adjustment. 
 7. Fractional Shares. No fractional shares of Series Preferred will be issued in connection with any exercise or conversion hereunder, but in lieu of such fractional shares the Company shall
make a cash payment therefor based on the fair market value of the Series Preferred on the date of exercise as reasonably determined in good faith by the Company’s Board of Directors. 

8. Compliance with Act: Disposition of Warrant or Shares of Series Preferred. 

(a) Compliance with Act. The Holder, by acceptance hereof, agrees that this Warrant, and the shares
of Series Preferred to be issued upon exercise hereof and any Common Stock issued upon conversion thereof are being acquired for investment and that the Holder will not offer, sell or otherwise dispose of this Warrant, or any shares of
Series Preferred to be issued upon exercise hereof or any Common Stock issued upon conversion thereof except under circumstances which will not result in a violation of the Act or any applicable state securities laws. Upon exercise of this
Warrant, unless the Shares being acquired are registered under the 

  

 
Act and any applicable state securities laws or an exemption from such registration is available, the Holder shall confirm in writing that the shares of Series Preferred so purchased (and
any Common Stock issued upon conversion thereof) are being acquired for investment and not with a view toward distribution or resale in violation of the Act and shall confirm such other matters related thereto as may be reasonably requested by the
Company. This Warrant and all shares of Series Preferred issued upon exercise of this Warrant and all Common Stock issued upon conversion thereof (unless registered under the Act and any applicable state securities laws) shall be stamped or
imprinted with a legend in substantially the following form: 
 “THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT AND SUCH LAWS, (ii) AN OPINION OF COUNSEL OR OTHER EVIDENCE,
REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED, OR (iii) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE PROVISIONS OF SECTION 8 OF THE
WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY.” 
 Said legend shall be removed
by the Company, upon the request of the Holder, at such time as the restrictions on the transfer of the applicable security shall have terminated. In addition, in connection with the issuance of this Warrant, the Holder specifically represents to
the Company by acceptance of this Warrant as follows: 
 (1) The Holder is aware of the
Company’s business affairs and financial condition, and has acquired information about the Company sufficient to reach an informed and knowledgeable decision to acquire this Warrant. The Holder is acquiring this Warrant for its own account for
investment purposes only and not with a view to, or for the resale in connection with, any “distribution” thereof in violation of the Act. 

(2) The Holder understands that this Warrant has not been registered under the Act in reliance upon a
specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. 

(3) The Holder further understands that this Warrant must be held indefinitely unless subsequently
registered under the Act and qualified under any applicable state securities laws, or unless exemptions from registration and qualification are otherwise available. The Holder is aware of the provisions of Rule 144, promulgated under the Act.

 (4) The Holder is an “accredited investor” as such term is defined in Rule 501 of
Regulation D promulgated under the Act. 
 (b) Disposition of Warrant or Shares. With
respect to any offer, sale or other disposition of this Warrant, any shares of Series Preferred acquired pursuant to the exercise of this Warrant or any shares of Common Stock acquired pursuant to conversion of Series Preferred, the Holder
agrees to give written notice to the Company prior thereto, 

  

 
describing briefly the manner thereof, together with a written opinion of counsel, or other evidence, if reasonably satisfactory to the Company, to the effect that such offer, sale or other
disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such shares of Series Preferred or Common Stock and indicating whether
or not under the Act certificates for this Warrant or such shares of Series Preferred or Common Stock to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure
compliance with such law. Upon receiving such written notice and reasonably satisfactory opinion or other evidence, the Company, as promptly as practicable but no later than fifteen (15) days after receipt of the written notice, shall notify
the Holder that the Holder may sell or otherwise dispose of this Warrant or such shares of Series Preferred or Common Stock, all in accordance with the terms of the notice delivered to the Company. If a determination has been made pursuant to
this Section 8(b) that the opinion of counsel or other evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such determination has been made. Notwithstanding the
foregoing, this Warrant or such shares of Series Preferred or Common Stock may, as to such federal laws, be offered, sold or otherwise disposed of (i) pursuant to an effective registration statement covering such securities or (ii) in
accordance with Rule 144 or 144A under the Act, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 or 144A have been
satisfied. Each certificate representing this Warrant or the shares of Series Preferred thus transferred (except a transfer pursuant to an effective registration statement or Rule 144 or 144A) shall bear a legend as to the applicable
restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions. 
 (c) Applicability
of Restrictions. Neither any restrictions of any legend described in this Warrant nor the requirements of Section 8(b) above shall apply to any transfer of, or grant of a security interest in, this Warrant (or the Series Preferred or
Common Stock obtainable upon exercise thereof) or any part hereof (i) to a partner of the Holder if the Holder is a partnership or to a member of the Holder if the Holder is a limited liability company, (ii) to a partnership of which the
Holder is a partner or to a limited liability company of which the Holder is a member, or (iii) to a single affiliate of the Holder if the Holder is a corporation, where, in each case, the transferee is an “accredited investor”;
provided, however, in any such transfer, if applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of this Warrant as if an original holder hereof. 

9. Rights as Shareholders; Information. No Holder, as a holder of this Warrant, shall be entitled to vote or
receive dividends or be deemed the holder of Series Preferred or any other securities of the Company which may at any time be issuable upon the exercise or conversion hereof for any purpose, nor shall anything contained herein be construed to
confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to receive notice of meetings, or to
receive dividends or subscription rights or otherwise until this Warrant shall have been exercised or converted and the Shares purchasable upon the exercise or conversion hereof shall have become deliverable, as provided herein. Notwithstanding the

  

 
foregoing, the Company will transmit to the Holder such information, documents and reports as are generally distributed to the holders of any class or series of the securities of the Company
concurrently with the distribution thereof to the shareholders. 
 10. Registration Rights. The Amended
and Restated Investor Rights Agreement, dated as of October 22, 2004, has been amended to extend to the Holder the rights thereunder as a “Purchaser” effective upon exercise hereof and execution of a counterpart thereof by the Holder.

 11. Additional Rights. 

(a) Acquisition Transactions. The Company shall provide the Holder with at least twenty
(20) days’ written notice prior to closing thereof of the terms and conditions of any Acquisition. 
 (b) Exercise Prior to Expiration. To the extent this Warrant is not previously exercised as to all of the Shares subject hereto, and if the fair market value of one share of the
Series Preferred is greater than the Warrant Price then in effect, this Warrant shall be deemed automatically exercised pursuant to Section 3(b) above (even if not surrendered) immediately before its expiration. For purposes of such
automatic exercise, the fair market value of one share of the Series Preferred upon such expiration shall be determined pursuant to Section 3(b). To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant
to this Section 11(b), the Company agrees to promptly notify the Holder of the number of Shares, if any, the Holder is to receive by reason of such automatic exercise. 

12. Representations and Warranties. The Company represents and warrants to the Holder as follows: 

(a) This Warrant has been duly authorized and executed by the Company and is a valid and binding
obligation of the Company enforceable in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and the rules of law or principles at equity governing specific performance,
injunctive relief and other equitable remedies. 
 (b) The Shares have been duly authorized and
reserved for issuance by the Company and, when issued in accordance with the terms hereof, will be validly issued, fully paid and nonassessable and free from preemptive rights. 

(c) The rights, preferences, privileges and restrictions granted to or imposed upon the Series Preferred
and the holders thereof are as set forth in the Charter as amended from time to time, and on the Date of Grant, each share of the Series Preferred represented by this Warrant is convertible into one share of Common Stock. 

(d) The shares of Common Stock issuable upon conversion of the Shares have been duly authorized and
reserved for issuance by the Company and, when issued in accordance with the terms of the Charter will be validly issued, fully paid and nonassessable. 

  

 (e) The execution and delivery of this Warrant are not, and
the issuance of the Shares upon exercise of this Warrant in accordance with the terms hereof will not be, inconsistent with the Company’s Charter or bylaws, do not and will not contravene any law, governmental rule or regulation, judgment or
order applicable to the Company, and do not and will not conflict with or contravene any provision of, or constitute a default under, any indenture, mortgage, contract or other instrument of which the Company is a party or by which it is bound or
require the consent or approval of, the giving of notice to, the registration or filing with or the taking of any action in respect of or by, any Federal, state or local government authority or agency or other person, except for the filing of
notices pursuant to federal and state securities laws, which filings will be effected by the time required thereby. 
 (f) There are no actions, suits, audits, investigations or proceedings pending or, to the knowledge of the Company, threatened against the Company in any court or before any governmental commission, board
or authority which, if adversely determined, could have a material adverse effect on the ability of the Company to perform its obligations under this Warrant. 

(g) The number of shares of Common Stock of the Company outstanding on the date hereof, on a fully diluted
basis (assuming the conversion of all outstanding convertible securities and the exercise of all outstanding options and warrants), does not exceed 82,600 shares. 

13. Modification and Waiver. This Warrant and any provision hereof may be changed, waived, discharged or
terminated only by an instrument in writing signed by the party against which enforcement of the same is sought. 
 14. Notices. Any notice, request, communication or other document required or permitted to be given or delivered to the Holder or the Company shall be delivered, or shall be sent by certified or
registered mail, postage prepaid, to the Holder at its address as shown on the books of the Company or to the Company at the address indicated therefor on the signature page of this Warrant. Such notice, request, communication or other document may
also be delivered by any other means of transmission so long as reasonable confirmation of receipt by the addressee is obtained. 
 15. Binding Effect on Successors. This Warrant shall be binding upon any corporation succeeding the Company by merger, consolidation or acquisition of all or substantially all of the Company’s
assets (except as expressly provided in Section 2), and all of the obligations of the Company relating to the Series Preferred issuable upon the exercise or conversion of this Warrant shall survive the exercise, conversion and termination
of this Warrant and all of the covenants and agreements of the Company shall inure to the benefit of the successors and assigns of the Holder. 
 16. Lost Warrants or Stock Certificates. The Company covenants to the Holder that, upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant or any stock certificate and, in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company, or in the case of any such mutilation upon surrender and cancellation of such Warrant
or stock certificate, the 

  

 
Company will make and deliver a new Warrant or stock certificate, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant or stock certificate. 

17. Descriptive Headings. The descriptive headings of the various Sections of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. The language in this Warrant shall be construed as to its fair meaning without regard to which party drafted this Warrant. 

18. Governing Law. This Warrant shall be construed and enforced in accordance with, and the rights of the parties
shall be governed by, the substantive laws of the State of California. 
 19. Survival of
Representations, Warranties and Agreements. All representations and warranties of the Company and the Holder contained herein shall survive the Date of Grant, the exercise or conversion of this Warrant (or any part hereof) or the
termination or expiration of rights hereunder. All agreements of the Company and the Holder contained herein shall survive indefinitely until, by their respective terms, they are no longer operative. 

20. Remedies. In case any one or more of the covenants and agreements contained in this Warrant shall have been
breached, the Holder (in the case of a breach by the Company), or the Company (in the case of a breach by the Holder), may proceed to protect and enforce their or its rights either by suit in equity and/or by action at law, including, but not
limited to, an action for damages as a result of any such breach and/or an action for specific performance of any such covenant or agreement contained in this Warrant. 

21. Severability. The invalidity or unenforceability of any provision of this Warrant in any jurisdiction shall

FORM OF 

VOCERA COMMUNICATIONS, INC. 
 WARRANT TO PURCHASE STOCK 
  

			
	 Number of Warrant Shares:
	  	______________
	 Class of Stock:
	  	Series E Preferred Stock (subject to Section 3.b. below)
	 Initial Exercise Price:
	  	$1.1019 per share
	 Issue Date:
	  	October     , 2005
	 Expiration Date:
	  	October    , 2015 (subject to Section 2.c. below)

 FOR VALUE RECEIVED, the receipt of which is hereby acknowledged, on or after the date of issuance of this warrant (this
“Warrant”), ____________ or its permitted assignee (the “Holder”) is entitled to purchase the number of fully paid and nonassessable shares of the class of securities (the “Warrant Shares”) of
Vocera Communications, Inc., a Delaware corporation (the “Company”) at the initial exercise price per Warrant Share (the “Exercise Price”) all as set forth above and as adjusted pursuant to Section 3 of this
Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. 
  

	1.	Exercise. 

 a. Method
of Exercise. Except as otherwise provided in Section 1.b. below, the Holder may exercise this Warrant, in whole or in part, by surrendering this Warrant and a duly executed Notice of Exercise in substantially the form attached hereto as
Appendix A to the principal office of the Company, or at such other office or agency as the Company may designate, accompanied by payment in full of the Exercise Price payable in respect of the number of Warrant Shares purchased upon such
exercise. The Exercise Price may be paid by cash, check or wire transfer. 
 b. Net Issue Exercise. 

(1) In lieu of exercising this Warrant in the manner provided above in Section 1.a., the Holder may elect to exercise
this Warrant in whole and receive shares equal to the value of this Warrant by surrender of this Warrant at the principal office of the Company together with notice of such election on the Notice of Exercise duly executed by such Holder, in which
event the Company shall issue to such Holder a number of Warrant Shares computed using the following formula: 
 X= Y
(A-B) 
     A 

 Where:      X = The number of Warrant Shares to be issued to the Holder. 

Y = The number of Warrant Shares purchasable under this Warrant pursuant to Section 1.a. (at the date of such calculation).

 A = The fair market value of one share of Warrant Shares (at the date of such calculation). 

B = The Exercise Price (as adjusted to the date of such calculation). 

(2) For purposes of this Section 1.b., if the Warrant Shares are traded regularly in a public market, the fair market
value of the Warrant Shares shall be the closing price of the Warrant Shares (or the closing price of the Company’s stock into which the Warrant Shares are convertible) reported for the business day immediately before Holder delivers its Notice
of Exercise to the Company. If the Warrant Shares are not regularly traded in a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment. 

c. “Easy Sale” Exercise. In lieu of the payment methods set forth above, when permitted by law and applicable
regulations (including the rules of Nasdaq and the National Association of Securities Dealers (the “NASD”), the Holder may pay the aggregate Exercise Price through a “same day sale” commitment from Holder (and if applicable a
broker-dealer that is a member of the NASD (an “NASD Dealer”), whereby the Holder will irrevocably elect to exercise this Warrant and to sell at least that number of shares of Warrant Stock purchased to immediately pay the aggregate
Exercise Price (and up to all of the Warrant Shares so purchased) and the Holder (or, if applicable, the NASD Dealer) commits upon sale (or, in the case of the NASD Dealer, upon receipt) of such Warrant Shares to forward the aggregate Exercise Price
directly to the Company, with any sale proceeds in excess of the aggregate Exercise Price being for the benefit of the Holder. 

d. Delivery of Certificate and New Warrant. Promptly after Holder exercises this Warrant, the Company shall deliver to the Holder
certificates for the Warrant Shares acquired and, if this Warrant has not been fully exercised and has not expired, a new warrant representing the right to purchase the Warrant Shares not so acquired. 

 

	2.	Effect of Acquisition of the Company. 

 a. “Acquisition.” For the purpose of this Warrant, “Acquisition” means any sale or other disposition of all or substantially all of the assets (including intellectual property)
of the Company, or any reorganization, consolidation, or merger of the Company where the holders of the Company’s securities before the transaction beneficially own, for or in consideration of their preexisting equity ownership in the Company,
less than 50% of the outstanding voting securities of the entity that succeeds to the business of the Company after the transaction. 
 b. Assumption of Warrant. If upon the closing of any Acquisition the successor entity expressly agrees to assume the obligations of this Warrant, then this Warrant shall be exercisable for the same
securities, cash, and/or property, if any, as would be payable for the Warrant Shares issuable upon exercise of the unexercised portion of this Warrant as if such 

  
 2 

 
Warrant Shares were outstanding on the record date for the Acquisition and subsequent closing. The Exercise Price shall be adjusted accordingly. 

c. Nonassumption. If upon the closing of any Acquisition the successor entity does not expressly agree to assume the obligations
of this Warrant and the Holder has not otherwise exercised this Warrant in full, then, notwithstanding Section 3.b., the Expiration Date of this Warrant will be the date of closing of such Acquisition; provided, that immediately prior to the
closing of such Acquisition, if the value of “X” in the calculation set forth in Section 1.b.(1) would be positive, this Warrant shall automatically be deemed to have been exercised by the holder thereof in the manner contemplated in
Section 1.b. hereof. 
 d. Notice. The Company will give the Holder not less than ten days notice of the closing of
any Acquisition. 
  

	3.	Adjustments. 

 a. Stock
Splits, Combinations and Dividends. If the outstanding Warrant Shares shall be subdivided into a greater number of shares or a dividend in such Warrant Shares shall be paid in respect thereof, the Exercise Price in effect immediately prior to
such subdivision or at the record date of such dividend shall simultaneously with the effectiveness of such subdivision or immediately after the record date of such dividend be proportionately reduced. If the outstanding Warrant Shares shall be
combined into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required to be made
in the Exercise Price, the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant
immediately prior to such adjustment, multiplied by the Exercise Price in effect immediately prior to such adjustment, by (ii) the Exercise Price in effect immediately after such adjustment. 

b. Reclassification, Exchange or Substitution. In case there occurs any reclassification or change of the outstanding securities
of the Company or any reorganization of the Company (or any other entity the stock or securities of which are at the time receivable upon the exercise of this Warrant) or any similar reorganization on or after the date hereof, then and in each such
case the Holder, upon the exercise hereof at any time after the consummation of such reclassification, change, or reorganization shall be entitled to receive, in lieu of the shares or other securities and property receivable upon the exercise hereof
prior to such consummation, the shares or other securities or property to which such Holder would have been entitled upon such consummation if such Holder had exercised this Warrant immediately prior thereto, all subject to further adjustment
pursuant to the provisions of this Section 3. This Section 3.b. expressly will apply when and if all of the outstanding shares of Series E Preferred Stock shall have been converted into Common Stock, in which case this Warrant
thereafter will be exercisable to purchase shares of Common Stock. 
 c. No Impairment. The Company shall not, by
amendment of its Certificate of Incorporation avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all times in good faith

  
 3 

 
assist in carrying out all the provisions of this Section 3 and in taking all such action as may be necessary or appropriate to protect the Holder’s rights under this Section 3
against impairment. 
 d. Certificate as to Adjustments. Upon each adjustment of the Exercise Price, the Company at its
expense shall promptly compute such adjustment, and furnish the Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request,
furnish the Holder a certificate setting forth the Exercise Price in effect upon the date thereof and the series of adjustments leading to such Exercise Price. 
  

	4.	Representations and Covenants of the Company. 

 a. Representations and Warranties. The Company hereby represents and warrants to the Holder that all Warrant Shares which may be issued upon the exercise of the purchase right represented by this
Warrant, and all securities, if any, issuable upon conversion of the Warrant Shares, shall, upon issuance, be duly authorized, validly issued, fully paid and nonassessable, and free of any liens and encumbrances created by or through the Company
except for restrictions on transfer provided for herein or under applicable federal and state securities laws. 
 b.
Reservation of Stock. The Company will at all times reserve and keep available, solely for the issuance and delivery upon the exercise of this Warrant, such Warrant Shares and other stock, securities and property, as from time to time shall
be issuable upon the exercise of this Warrant. 
  

	5.	Transfers. 

 a.
Compliance with Securities Laws on Transfer. This Warrant and the Warrant Shares issuable upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion of the Warrant Shares, if any) may not be
transferred or assigned in whole or in part without compliance with applicable federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment representation letters and legal
opinions reasonably satisfactory to the Company). The Company shall not require the Holder to provide an opinion of counsel if the transfer is to an affiliate of the Holder or if there is no material question as to the availability of current
information as referenced in Rule 144( c), the Holder represents that it has complied with Rule 144(d) and (e) in reasonable detail, the selling broker represents that it has complied with Rule 144(f), and the Company is
provided with a copy of the Holder’s notice of proposed sale. 
 b. Transfer Procedure. Subject to the provisions of
Section 5.a. hereof, the Holder may transfer all or part of this Warrant or the Warrant Shares issuable upon exercise of this Warrant (or the securities issuable, directly or indirectly, upon conversion of the Warrant Shares, if any) upon
surrender of the Warrant or the certificates representing the Warrant Shares issuable upon exercise of this Warrant together with a properly executed Notice of Transfer in substantially the form attached hereto as Appendix B to the principal
office of the Company; provided, however, that the Holder may transfer all or part of this Warrant to its affiliates at any time without notice to the Company, and such affiliate shall then be entitled to all the rights of Holder under
this Warrant and any related agreements, and the Company shall cooperate fully in 

  
 4 

 
ensuring that any stock issued upon exercise of this Warrant is issued in the name of the affiliate that exercises the warrant. The terms and conditions of this Warrant shall inure to the benefit
of, and be binding upon, the Company and the holders hereof and their respective permitted successors and assigns. Unless the Company is filing financial information with the SEC pursuant to the Securities Exchange Act of 1934, the Company shall
have the right to refuse to transfer any portion of this Warrant to any person who directly competes with the Company. 
  

	6.	Miscellaneous. 

 a.
Term. This Warrant is exercisable in whole or in part, at any time and from time to time on or before the Expiration Date set forth above except as otherwise provided herein. The Company hereby acknowledges that exercise of this Warrant by
the Holder may subject the Company and/or the Holder to the filing requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) and that the Holder may be prevented from exercising this Warrant until the
expiration or early termination of all waiting periods imposed by the HSR Act (“HSR Act Restrictions”). If on or before the Expiration Date the Holder has sent a notice of exercise of this Warrant to the Company and Holder has not been
able to complete the exercise of this Warrant prior to the Expiration Date because of HSR Act Restrictions, the Expiration Date shall be extended until such time as such HSR Act Restrictions have terminated. The prior sentence may not be amended or
waived without the approval of the Holder, notwithstanding anything else herein. 
 b. Fractional Shares. No fractional
Warrant Shares shall be issuable upon exercise or conversion of the Warrant and the number of Warrant Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the
Warrant, the Company shall eliminate such fractional share interest by paying Holder an amount computed by multiplying the fractional interest by the fair market value of a full Warrant Share, determined per Section 1.b.(2). In determining
whether fractional shares are issuable upon the exercise or conversion of this Warrant, the Company shall aggregate all Warrant Shares issuable to the holder at the time of such exercise or conversion. 

c. Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 
 d. No Rights
as a Stockholder. Until the exercise of this Warrant, the Holder of this Warrant shall not have or exercise any rights by virtue hereof as a stockholder of the Company. 
 e. Legends. This Warrant and the Warrant Shares (and the securities issuable, directly or indirectly, upon conversion of the Warrant Shares, if any) shall be imprinted with a legend in
substantially the form set forth on the first page hereof. 
 f. Notices. All notices and other communications from the
Company to the Holder, or vice versa, shall be deemed delivered and effective when given personally or mailed by first 

  
 5 

 
class registered or certified mail, postage prepaid, at such address as may have been furnished to the Company or the Holder, as the case may be, in writing by the Company or such Holder from
time to time. All notices to the Holder shall be addressed as follows: 
 _________________ 

_________________ 
 _________________ 

g. Amendments. This Warrant and any term hereof may be changed, waived, discharged or terminated only by (1) an instrument in
writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought; or (2) by written approval of the Company and Majority Holders provided, that any proposed amendment or waiver that does not
affect all holders of Joinder Warrants in a similar manner (with respect to such Joinder Warrants) shall require the prior written consent of such person (or a majority of all similarly affected persons). This Warrant is one of a number of warrants
of substantially similar terms issued pursuant to that certain “Joinder Agreement” dated October     , 2005 (collectively, the “Joinder Warrants”). For this purpose, “Majority Holders”
will refer to the holders of a majority in interest of the Joinder Warrants (based on shares issuable upon the exercise of then outstanding Joinder Warrants). 
 h. Attorneys’ Fees. In the event of any dispute between the parties concerning the terms and provisions of this Warrant, the party prevailing in such dispute shall be entitled to collect from
the other party all costs incurred in such dispute, including reasonable attorneys’ fees. 
 i. Headings. The
headings in this Warrant are for purposes of reference only and shall not limit or otherwise affect the meaning of any provision of this Warrant. 
 j. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of California, without giving effect to its principles regarding conflicts of law.
