number of shares of Stock that may be issued under the Plan shall be thirteen million eight hundred thirty two thousand three hundred eighty (13,832,380) and shall consist of authorized but unissued or reacquired shares of Stock or any combination
thereof. If an outstanding Option for any reason expires or is terminated or canceled or if shares of Stock are acquired upon the exercise of an Option subject to a Company repurchase option and are repurchased by the Company at the Optionee’s
exercise price, the shares of Stock allocable to the unexercised portion of such Option or such repurchased shares of Stock shall again be available for issuance under the Plan. However, except as adjusted pursuant to Section 4.2, in no event
shall more than thirteen million eight hundred thirty two thousand three hundred eighty (13,832,380) shares of Stock be available for issuance pursuant to the exercise of Incentive Stock Options (the “ISO Share Issuance
Limit”). Notwithstanding the foregoing, at any such time as the offer and sale of securities pursuant to the Plan is subject to compliance with Section 260.140.45 of Title 10 of the California Code of Regulations
(“Section 260.140.45”), the total number of shares of Stock issuable upon the exercise of all outstanding Options (together with options outstanding under any other stock option plan of the Company) and the total number of
shares provided for under any stock bonus or similar plan of the Company shall not exceed thirty percent (30%) (or such other higher percentage limitation as may be approved by the stockholders of the Company pursuant to
Section 260.140.45) of the then outstanding shares of the Company as calculated in accordance with the conditions and exclusions of Section 260.140.45. 

4.2 Adjustments for Changes in Capital Structure. In the event of any stock dividend, stock split, reverse stock
split, recapitalization, combination, reclassification or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number and class of shares subject to the Plan and to any outstanding Options, in the ISO
Share Issuance Limit set forth in Section 4.1, and in the exercise price per share of any outstanding Options. If a majority of the shares which are of the same class as the shares that are subject to outstanding Options are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership Change Event, as defined in Section 8.1) shares of another corporation (the “New Shares”), the Board may unilaterally amend the outstanding
Options to provide that such Options are exercisable for New Shares. In the event of any such amendment, the number of shares subject to, and the exercise price per share of, the outstanding Options shall be adjusted in a fair and equitable manner
as determined by the Board, in its discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 4.2 shall be 

 
rounded down to the nearest whole number, and in no event may the exercise price of any Option be decreased to an amount less than the par value, if any, of the stock subject to the Option. The
adjustments determined by the Board pursuant to this Section 4.2 shall be final, binding and conclusive. 
  

	5.	 ELIGIBILITY AND OPTION LIMITATIONS. 

5.1 Persons Eligible for Options. Options may be granted only to Employees, Consultants, and Directors. For
purposes of the foregoing sentence, “Employees,” “Consultants” and “Directors” shall include prospective Employees, prospective Consultants and prospective Directors to whom Options are granted in connection with
written offers of an employment or other service relationship with the Participating Company Group. Eligible persons may be granted more than one (1) Option. However, eligibility in accordance with this Section shall not entitle any person to
be granted an Option, or, having been granted an Option, to be granted an additional Option. 
 5.2 Option
Grant Restrictions. Any person who is not an Employee on the effective date of the grant of an Option to such person may be granted only a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective Employee upon the condition
that such person become an Employee shall be deemed granted effective on the date such person commences Service with a Participating Company, with an exercise price determined as of such date in accordance with Section 6.1. 

5.3 Fair Market Value Limitation. To the extent that options designated as Incentive Stock Options (granted under
all stock option plans of the Participating Company Group, including the Plan) become exercisable by an Optionee for the first time during any calendar year for stock having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000),
the portions of such options which exceed such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section 5.3, options designated as Incentive Stock Options shall be taken into account in the order in which they were
granted, and the Fair Market Value of stock shall be determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a different limitation from that set forth in this Section 5.3, such
different limitation shall be deemed incorporated herein effective as of the date and with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated as an Incentive Stock Option in part and as a
Nonstatutory Stock Option in part by reason of the limitation set forth in this Section 5.3, the Optionee may designate which portion of such Option the Optionee is exercising. In the absence of such designation, the Optionee shall be deemed to
have exercised the Incentive Stock Option portion of the Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. 

 

	6.	 TERMS AND CONDITIONS OF OPTIONS. 

Options shall be evidenced by Option Agreements specifying the number of shares of Stock covered thereby, in such form as
the Board shall from time to time establish. No Option or purported Option shall be a valid and binding obligation of the Company unless evidenced by a fully executed Option Agreement. Option Agreements may incorporate all or any of the terms of

 
the Plan by reference and shall comply with and be subject to the following terms and conditions: 
 6.1 Exercise Price. The exercise price for each Option shall be established in the discretion of the Board; provided, however, that (a) the exercise price per share for an Incentive Stock
Option shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option, (b) the exercise price per share for a Nonstatutory Stock Option shall be not less than eighty-five percent (85%) of the
Fair Market Value of a share of Stock on the effective date of grant of the Option, and (c) no Option granted to a Ten Percent Owner Optionee shall have an exercise price per share less than one hundred ten percent (110%) of the Fair
Market Value of a share of Stock on the effective date of grant of the Option. Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an exercise price lower than the minimum
exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another option in a manner qualifying under the provisions of Section 424(a) of the Code. 

6.2 Exercisability and Term of Options. Options shall be exercisable at such time or times, or upon such event or
events, and subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Board and set forth in the Option Agreement evidencing such Option; provided, however, that (a) no Option shall be exercisable
after the expiration of ten (10) years after the effective date of grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent Owner Optionee shall be exercisable after the expiration of five (5) years after the
effective date of grant of such Option, (c) no Option granted to a prospective Employee, prospective Consultant or prospective Director may become exercisable prior to the date on which such person commences Service with a Participating
Company. and (d) with the exception of an Option granted to an officer, Director or Consultant, no Option shall become exercisable at a rate less than twenty percent (20%) per year over a period of five (5) years from the effective
date of grant of such Option, subject to the Optionee’s continued Service. Subject to the foregoing, unless otherwise specified by the Board in the grant of an Option, any Option granted hereunder shall terminate ten (10) years after the
effective date of grant of the Option, unless earlier terminated in accordance with its provisions. 
 Notwithstanding contrary
terms contained in any Option Agreement (whether executed before or after the date of effectiveness of the Plan amendment incorporating this sentence and the following sentences of this Section 6.2) applicable to an Optionee: 

(a) if such Optionee is not permitted, under the terms of such Optionee’s Option Agreement, to
exercise all or a portion of such Optionee’s Option due to vesting restrictions, such Optionee may exercise any portion of such Option that has not yet vested, provided that the shares issued upon such exercise will be “Unvested
Shares.” 
 (b) Unvested Shares referred to in (a), above, will become Vested Shares at the
same rate and on the same basis that the Option underlying same would have become vested, collectively with any portion of the Option that has not been exercised, under the terms of Optionee’s Option Agreement. If at any time there is a choice
as to whether to 

 
vest exercised portions of the Option or Unvested Shares, vesting will be applied to Unvested Shares. 

(c) Effective with any termination of Optionee’s Service, the Company will have the assignable right,
exercisable no later than 90 days after such termination, to repurchase for cash all or portion of such Unvested Shares at the Exercise Price per share paid by Optionee for such Unvested Shares.

(a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the exercise
price for the number of shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check or cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of shares of Stock owned by the Optionee

the exercise price, (iii) by delivery of a properly executed notice together with irrevocable instructions to a broker providing for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares being
acquired upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System) (a
“Cashless Exercise”), (iv) provided that the Optionee is an Employee (unless otherwise not prohibited by law, including, without limitation, any regulation promulgated by the Board of Governors of the Federal Reserve
System) and in the Company’s sole discretion at the time the Option is exercised, by delivery of the Optionee’s promissory note in a form approved by the Company for the aggregate exercise price, provided that, if the Company is
incorporated in the State of Delaware, the Optionee shall pay in cash that portion of the aggregate exercise price not less than the par value of the shares being acquired, (v) by such other consideration as may be approved by the Board from
time to time to the extent permitted by applicable law, or (vi) by any combination thereof. The Board may at any time or from time to time, by approval of or by amendment to the standard forms of Option Agreement described in Section 7, or
by other means, grant Options which do not permit all of the foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration. 

(b) Limitations on Forms of Consideration. 

(i) Tender of Stock. Notwithstanding the foregoing, an Option may not be exercised by tender to the
Company, or attestation to the ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. Unless
otherwise provided by the Board, an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months (and not used
for another Option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company. 

 (ii) Cashless Exercise. The Company reserves, at any
and all times, the right, in the Company’s sole and absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise. 

(iii) Payment by Promissory Note. No promissory note shall be permitted if the exercise of an
Option using a promissory note would be a violation of any law Any permitted promissory note shall be on such terms as the Board shall determine at the time the Option is granted. The Board shall have the authority to permit or require the Optionee
to secure any promissory note used to exercise an Option with the shares of Stock acquired upon the exercise of the Option or with other collateral acceptable to the Company. Unless otherwise provided by the Board, if the Company at any time is
subject to the regulations promulgated by the Board of Governors of the Federal Reserve System or any other governmental entity affecting the extension of credit in connection with the Company’s securities, any promissory note shall comply with
such applicable regulations, and the Optionee shall pay the unpaid principal and accrued interest, if any, to the extent necessary to comply with such applicable regulations. 

6.4 Tax Withholding. The Company shall have the right, but not the obligation, to deduct from the shares of Stock
issuable upon the exercise of an Option, or to accept from the Optionee the tender of, a number of whole shares of Stock having a Fair Market Value, as determined by the Company, equal to all or any part of the federal, state, local and foreign
taxes, if any, required by law to be withheld by the Participating Company Group with respect to such Option or the shares acquired upon the exercise thereof. Alternatively or in addition, in its discretion, the Company shall have the right to
require the Optionee, through payroll withholding, cash payment or otherwise, including by means of a Cashless Exercise, to make adequate provision for any such tax withholding obligations of the Participating Company Group arising in connection
with the Option or the shares acquired upon the exercise thereof. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall not exceed the amount determined by the applicable minimum
statutory withholding rates. The Company shall have no obligation to deliver shares of Stock or to release shares of Stock from an escrow established pursuant to the Option Agreement until the Participating Company Group’s tax withholding
obligations have been satisfied by the Optionee. 
 6.5 Repurchase Rights. Shares issued under the Plan
may be subject to a right of first refusal, one or more repurchase options, or other conditions and restrictions as determined by the Board in its discretion at the time the Option is granted. The Company shall have the right to assign at any time
any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. Upon request by the Company, each Optionee shall execute any agreement evidencing such transfer restrictions
prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such
transfer restrictions.

(a) Option Exercisability. Subject to earlier termination of the Option as otherwise provided
herein and unless otherwise provided by the Board in the grant of an Option and set forth in the Option Agreement, an Option shall be exercisable after an Optionee’s termination of Service only during the applicable time period determined in
accordance with this Section 6.6 and thereafter shall terminate: 
 (i) Disability.
If the Optionee’s Service with the Participating company Group terminates because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be
exercised by the Optionee (or the Optionee’s guardian or legal representative) at any time prior to the expiration of twelve (12) months (or such longer period of time as determined by the Board, in its discretion) after the date on which
the Optionee’s Service terminated, but in any event no later than the date of expiration of the Option’s term as set forth in the Option Agreement evidencing such Option (the “Option Expiration Date”). 

(ii) Death. If the Optionee’s Service with the Participating Company Group terminates because
of the death of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the right to
exercise the Option by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months (or such longer period of time as determined by the Board, in its discretion) after the date on which the Optionee’s
Service terminated, but in any event no later than the Option Expiration Date. The Optionee’s Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months (or such longer period of time as
determined by the Board, in its discretion) after the Optionee’s termination of Service. 

(iii) Other Termination of Service. If the Optionee’s Service with the Participating Company
Group terminates for any reason, except Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee at any time prior to the

(b) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of an
Option within the applicable time periods set forth in Section 6.6(a) is prevented by the provisions of Section 10 below, the Option shall remain exercisable until three (3) months (or such longer period of time as determined by the
Board, in its discretion) after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Expiration Date. 

(c) Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if a sale

Options. During the lifetime of the Optionee, an Option shall be exercisable only by the Optionee or the Optionee’s guardian or legal representative. No Option shall be assignable or transferable by the Optionee, except by will or by the
laws of descent and distribution. Notwithstanding the foregoing, to the extent permitted by the Board, in its discretion, and set forth in the Option Agreement evidencing such Option, a Nonstatutory Stock Option shall be assignable or transferable
subject to the applicable limitations, if any, described in Section 260.140.41 of Title 10 of the California Code of Regulations, Rule 701 under the Securities Act, and the General Instructions to Form S-8 Registration Statement under the
Securities Act. 
  

	7.	 STANDARD FORMS OF OPTION AGREEMENT. 

7.1 Option Agreement. Unless otherwise provided by the Board at the time the Option is granted, an Option shall
comply with and be subject to the terms and conditions set forth in the form of Option Agreement approved by the Board concurrently with its adoption of the Plan and as amended from time to time. 

7.2 Authority to Vary Terms. The Board shall have the authority from time to time to vary the terms of any
standard form of Option Agreement described in this Section 7 either in connection with the grant or amendment of an individual Option or in connection with the authorization of a new standard form or forms; provided, however, that the terms
and conditions of any such new, revised or amended standard form or forms of Option Agreement are not inconsistent with the terms of the Plan. 
  

	8.	 CHANGE IN CONTROL. 

8.1 Definitions. 

(a) An “Ownership Change Event” shall be deemed to have occurred if any of the
following occurs with respect to the Company: (i) the direct or indirect sale or exchange in a single or series of related transactions by the stockholders of the Company of more than fifty percent (500/0) of the voting stock of the
Company; (ii) a merger or consolidation in which the Company is a party; (iii) the sale, exchange, or transfer of all or substantially all of the assets of the Company; or (iv) a liquidation or dissolution of the Company. 

(b) A “Change in Control” shall mean an Ownership Change Event or a series of
related Ownership Change Events (collectively, a “Transaction”) wherein the stockholders of the Company immediately before the Transaction do not retain immediately after the Transaction, in substantially the same proportions
as their ownership of shares of the Company’s voting stock immediately before the Transaction, direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding voting stock of
the Company or, in the case of a Transaction described in Section 8.1(a)(iii), the corporation or corporations to which the assets of the Company were transferred (the “Transferee Corporation(s)”), as the case may be.
For purposes of the preceding sentence, 

 
indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting stock of one or more corporations which, as a result of the Transaction, own
the Company or the Transferee Corporation(s), as the case may be, either directly or through one or more subsidiary corporations. The Board shall have the right to determine whether multiple sales or exchanges of the voting stock of the Company or
multiple Ownership Change Events are related, and its determination shall be final, binding and conclusive. 

8.2 Effect of Change in Control on Options. In the event of a Change in Control, the surviving, continuing,
successor, or purchasing corporation or parent corporation thereof, as the case may be (the “Acquiring Corporation”), may either assume the Company’s rights and obligations under outstanding Options or substitute for
outstanding Options substantially equivalent options for the Acquiring Corporation’s stock. In the event the Acquiring Corporation elects not to assume the Company’s rights and obligations under the Option or substitute for the Option in
connection with the Change in Control, and provided that the Optionee’s Service has not terminated prior to such date, any unexercised or unvested portion of the Option shall be immediately exercisable and vested in full as of the date ten
(10) days prior to the date of the Change in Control. Any exercise or vesting of the Option that was permissible solely by reason of this Section 8.2 shall be conditioned upon the consummation of the Change in Control. Any Options which
are neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control shall terminate and cease to be outstanding effective as of the date of the Change in Control. Notwithstanding the foregoing, shares
acquired upon exercise of an Option prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of the Option Agreement
evidencing such Option except as otherwise provided in such Option Agreement. 
  

	9.	 PROVISION OF INFORMATION. 

At least annually, copies of the Company’s balance sheet and income statement for the just completed fiscal year
shall be made available to each Optionee and purchaser of shares of Stock upon the exercise of an Option. The Company shall not be required to provide such information to key employees whose duties in connection with the Company assure them access
to equivalent information. 
  

	10.	 COMPLIANCE WITH SECURITIES LAW. 

The grant of Options and the issuance of shares of Stock upon exercise of Options shall be subject to compliance with all
applicable requirements of federal, state and foreign law with respect to such securities. Options may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign
securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, no Option may be exercised unless (a) a registration statement under the Securities Act
shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (b) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in
accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the

 
authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability in respect of the
failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of any Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or
appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 

 

	11.	 TERMINATION OR AMENDMENT OF PLAN. 

The Board may terminate or amend the Plan at any time. However, subject to changes in applicable law, regulations or rules
that would permit otherwise, without the approval of the Company’s stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of
Section 4.2), (b) no change in the class of persons eligible to receive Incentive Stock Options, and (c) no other amendment of the Plan that would require approval of the Company’s stockholders under any applicable law,
regulation or rule. No termination or amendment of the Plan shall affect any then outstanding Option unless expressly provided by the Board. In any event, no termination or amendment of the Plan may adversely affect any then outstanding Option
without the consent of the Optionee, unless such termination or amendment is required to enable an Option designated as an Incentive Stock Option to qualify as an Incentive Stock Option or is necessary to comply with any applicable law, regulation
or rule. 
  

	12.	 STOCKHOLDER APPROVAL. 

The Plan or any increase in the maximum aggregate number of shares of Stock issuable thereunder as provided in Section 4.1 (the
“Authorized Shares”) shall be approved by the stockholders of the Company within twelve (12) months of the date of adoption thereof by the Board. Options granted prior to stockholder approval of the Plan or in excess of the Authorized
Shares previously approved by the stockholders shall become exercisable no earlier than the date of stockholder approval of the Plan or such increase in the Authorized Shares, as the case may be.

 PLAN HISTORY 
 The original 2000 Stock Option Plan was amended by the Board on October 13 2005 and by the Stockholders as of October 14, 2005 to permit early exercise by employees, and by the Board as of
March 30, 2006 and by the Stockholders as of April 13, 2006 to increase the maximum number of shares of stock that may be issued under the Plan to 14, 365,000. 
 This Amended and Restated 2000 Plan was created to reflect these two amendments. 

 Amendment to Vocera Communications, Inc. 

2000 Stock Option Plan 
 Vocera Communications, Inc. (the “Company”) originally adopted the Vocera Communications, Inc. 2000 Stock Option Plan effective as of March 1, 2000. As previously amended, such 2000 Stock
Option Plan is referred to as the “Plan.” Except as otherwise provided herein, capitalized terms used herein will have the meanings set forth in the Plan. 
 The Plan is hereby amended as follows: 
 1. The following language is added to the
end of Section 6.2 of the Plan: 
 Notwithstanding contrary terms contained in any Option Agreement (whether
executed before or after the date of effectiveness of the Plan amendment incorporating this sentence and the following sentences of this Section 6.2) applicable to an Optionee who is an Employee: 

(a) if such Optionee is not permitted, under the terms of such Optionee’s Option Agreement, to exercise all or a
portion of such Optionee’s Option due to vesting restrictions, such Optionee may exercise any portion of such Option that has not yet vested so long as such Optionee is an Employee, provided that the shares issued upon such exercise will be
“Unvested Shares.” 
 (b) Unvested Shares referred to in (a), above, will become Vested Shares at the
same rate and on the same basis that the Option underlying same would have become vested, collectively with any portion of the Option that has not been exercised, under the terms of Optionee’s Option Agreement. If at any time there is a choice
as to whether to vest exercised portions of the Option or Unvested Shares, vesting will be applied to Unvested Shares. 
 (c) Effective with any termination of Optionee’s Service as an Employee, the Company will have the assignable right, exercisable no later than 90 days after such termination, to repurchase for cash
all or portion of such Unvested Shares at the Exercise Price per share paid by Optionee for such Unvested Shares. 
 2. If this
Amendment of the Plan is not approved by the holders of a majority of the outstanding Shares of the Company within twelve months of the effective date set forth above, then this Amendment will be null and void. 

3. The Company is authorized to amend and restate the Plan to reflect the foregoing amendment of Section 6.2 thereof. 

4. Except as amended hereby, the Plan will continue in full force and effect. 

 Approval of the foregoing amendment by the Board of Directors of the Company is hereby
acknowledged by the below signature of the Secretary of the Company:

 Vocera Communications, Inc. 

Stock Option Agreement 
 Vocera Communications, Inc. has granted to the individual (the “Optionee”) named in the Notice of Grant of Stock Option (the
“Notice”) to which this Stock Option Agreement (the “Option Agreement”) is attached an option (the “Option”) to purchase certain shares
of Stock upon the terms and conditions set forth in the Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects be subject to the terms and conditions of the Vocera Communications, Inc. 2000 Stock Option
Plan (the “Plan”), as amended to the Date of Option Grant, the provisions of which are incorporated herein by reference. By signing the Notice, the Optionee: (a) represents that the Optionee has read and is
familiar with the terms and conditions of the Notice, the Plan and this Option Agreement, including the Effect of Termination of Service set forth in Section 7 and the Right of First Refusal set forth in Section 11, (b) accepts the
Option subject to all of the terms and conditions of the Notice, the Plan and this Option Agreement, (c) agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under the
Notice, the Plan or this Option Agreement, and (d) acknowledges receipt of a copy of the Notice, the Plan and this Option Agreement. 
  

	 	1.	 DEFINITIONS AND CONSTRUCTION. 

1.1 Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings
assigned to such terms in the Notice or the Plan. 
 1.2 Construction. Captions
and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural
shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise. 
  

	 	2.	 TAX CONSEQUENCES. 

2.1 Tax Status of Option. This Option is intended to have the tax status designated in the
Notice. 
 (a) Incentive Stock Option. If the Notice so designates, this Option is
intended to be an Incentive Stock Option within the meaning of Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such. The Optionee should consult with the Optionee’s own tax advisor
regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to, holding period requirements. (NOTE TO OPTIONEE: If the Option is
exercised more than three (3) months after the date on which you cease to be an Employee (other than by reason of your death or permanent and total disability as defined in Section 22(e)(3) of the Code), the Option will be treated as a
Nonstatutory Stock Option and not as an Incentive Stock Option to the extent required by Section 422 of the Code.) 

 (b) Nonstatutory Stock Option. If the
Notice so designates, this Option is intended to be a Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option within the meaning of Section 422(b) of the Code. 

2.2 ISO Fair Market Value Limitation. If the Notice designates this Option as an Incentive Stock
Option, then to the extent that the Option (together with all Incentive Stock Options granted to the Optionee under all stock option plans of the Participating Company Group, including the Plan) becomes exercisable for the first time during any
calendar year for shares having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options. For purposes of this Section 2.2,
options designated as Incentive Stock Options are taken into account in the order in which they were granted, and the Fair Market Value of stock is determined as of the time the option with respect to such stock is granted. If the Code is amended to
provide for a different limitation from that set forth in this Section 2.2, such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. If the Option is treated as
an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this Section 2.2, the Optionee may designate which portion of such Option the Optionee is exercising. In the absence of such
designation, the Optionee shall be deemed to have exercised the Incentive Stock Option portion of the Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. (NOTE TO OPTIONEE: If the
aggregate Exercise Price of the Option (that is, the Exercise Price multiplied by the Number of Option Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or any other stock
option plan of the Participating Company Group) is greater than $100,000, you should contact the Chief Financial Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.) 

 

	 	3.	 ADMINISTRATION. 

 All questions of interpretation concerning this Option Agreement shall be determined by the Board. All determinations by the Board shall be final and binding upon all persons having an interest in the
Option. Any officer of a Participating Company shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided
the officer has apparent authority with respect to such matter, right, obligation, or election. 
  

	 	4.	 EXERCISE OF THE OPTION. 

4.1 Right to Exercise. Except as otherwise provided herein, the Option shall be exercisable
on and after the Initial Vesting Date and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the number of Vested Shares less the number of shares previously acquired upon exercise of the Option,
subject to the Company’s repurchase rights set forth in Section 11. In no event shall the Option be exercisable for more shares than the Number of Option Shares. 

4.2 Method of Exercise. Exercise of the Option shall be by written notice to the Company
which must state the election to exercise the Option, the number of whole shares of 

 
Stock for which the Option is being exercised and such other representations and agreements as to the Optionee’s investment intent with respect to such shares as may be required pursuant to
the provisions of this Option Agreement. The written notice must be signed by the Optionee and must be delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the
Company may permit, to the Chief Financial Officer of the Company, or other authorized representative of the Participating Company Group, prior to the termination of the Option as set forth in Section 6, accompanied by full payment of the
aggregate Exercise Price for the number of shares of Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such written notice and the aggregate Exercise Price. 

4.3 Payment of Exercise Price. 

(a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the
aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check, or cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of whole shares of
Stock owned by the Optionee having a Fair Market Value (as determined by the Company without regard to any restrictions on transferability applicable to such stock by reason of federal or state securities laws or agreements with an underwriter for
the Company) not less than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as defined in Section 4.3(b), (iv) provided the Optionee is an Employee (unless otherwise not prohibited by law, including, without
limitation, any regulation promulgated by the Board of Governors of the Federal Reserve System) and in the Company’s sole discretion at the time the Option is exercised, by delivery of the Optionee’s promissory note in a form approved by
the company for the aggregate Exercise Price, provided that, if the Company is incorporated in the state of Delaware, the Optionee shall pay in cash that portion of the aggregate Exercise Price not less than the par value of the shares being
acquired, or (v) by any combination of the foregoing. 
 (b) Limitations on Forms of
Consideration. 
 (i) Tender of Stock. Notwithstanding the foregoing, the Option
may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption
of the Company’s stock. The Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not
acquired, directly or indirectly, from the Company. 
 (ii) Cashless Exercise. A
“Cashless Exercise” means the delivery of a properly executed notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the
proceeds of a sale or loan with respect to some or all of the shares of Stock acquired upon the exercise of the Option pursuant to a program or procedure approved by the Company (including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). The Company 

 
reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to decline to approve or terminate any such program or procedure. 

(iii) Payment by Promissory Note. No promissory note shall be permitted if an exercise of the
Option using a promissory note would be a violation of any law. Unless otherwise specified by the Board at the time the Option is granted, the promissory note permitted in clause (iv) of Section 4.3(a) shall be a full recourse note in a
form satisfactory to the Company. Such recourse promissory note shall be secured by the shares of Stock acquired pursuant to the then current form of security agreement as approved by the Company. At any time the Company is subject to the
regulations promulgated by the Board of Governors of the Federal Reserve System or any other governmental entity affecting the extension of credit in connection with the Company’s securities, any promissory note shall comply with such
applicable regulations, and the Optionee shall pay the unpaid principal and accrued interest, if any, to the extent necessary to comply with such applicable regulations. The Company in its sole discretion, may require the Optionee to pay the unpaid
principal balance of the promissory note and any accrued interest thereon upon termination of the Optionee’s Service with the Participating Company Group for any reason, with or without cause. 

4.4 Tax Withholding. At the time the Option is exercised, in whole or in part, or at any
time thereafter as requested by the Company, the Optionee hereby authorizes withholding from payroll and any other amounts payable to the Optionee, and otherwise agrees to make adequate provision for (including by means of a Cashless Exercise to the
extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company Group, if any, which arise in connection with the Option, including, without limitation,
obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired upon exercise of the Option, (iii) the operation of any law or regulation providing for the
imputation of interest, or (iv) the lapsing of any restriction with respect to any shares acquired upon exercise of the Option. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the
Participating Company Group have been satisfied by the Optionee. 
 4.5 Certificate
Registration. Except in the event the Exercise Price is paid by means of a Cashless Exercise, the certificate for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, in the
names of the heirs of the Optionee. 
 4.6 Restrictions on Grant of the Option and Issuance of
Shares. The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option
may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system
upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon
exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with 

 
the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE
SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the
Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority
shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to
make any representation or warranty with respect thereto as may be requested by the Company. 

4.7 Fractional Shares. The Company shall not be required to issue fractional shares upon the
exercise of the Option. 
  

	 	5.	 NONTRANSFERABILITY OF THE OPTION. 

 The Option may be exercised during the lifetime of the Optionee only by the Optionee or the Optionee’s guardian or legal representative and may not be assigned or transferred in any manner except by
will or by the laws of descent and distribution. Following the death of the Optionee, the Option, to the extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person empowered to do so under the
deceased Optionee’s will or under the then applicable laws of descent and distribution. 
  

	 	6.	 TERMINATION OF THE OPTION. 

 The Option shall terminate and may no longer be exercised on the first to occur of (a) the Option Expiration Date, (b) the last date for exercising the Option following termination of the
Optionee’s Service as described in Section 7, or (c) a Change in Control to the extent provided in Section 8. 
  

	 	7.	 EFFECT OF TERMINATION OF SERVICE. 

7.1 Option Exercisability. 

(a) Disability. If the Optionee’s Service with the Participating Company Group
terminates because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or legal
representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 

(b) Death. If the Optionee’s Service with the Participating Company Group terminates
because of the death of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the
right to exercise the Option by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the 

 
date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. The Optionee’s Service shall be deemed to have terminated on account of death
if the Optionee dies within thirty (30) days after the Optionee’s termination of Service. 
 (c) Other Termination of Service. If the Optionee’s Service with the Participating Company Group terminates for any reason, except Disability or death, the Option, to the extent
unexercised and exercisable by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee at any time prior to the expiration of ninety (90) days (or such other longer period of time as determined
by the Board, in its discretion) after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 

7.2 Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise
of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until thirty (30) days after the date the Optionee is notified by the Company
that the Option is exercisable, but in any event no later than the Option Expiration Date. 
 7.3
Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if a sale within the applicable time periods set forth in Section 7.1 of shares acquired upon the exercise of the Option would subject the Optionee to
suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Optionee would no longer be subject to
such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee’s termination of Service, or (iii) the Option Expiration Date. 
  

	 	8.	 CHANGE IN CONTROL. 

 In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or parent corporation thereof, as the case may be (the “Acquiring
Corporation”), may either assume the Company’s rights and obligations under the Option or substitute for the Option a substantially equivalent option for the Acquiring Corporation’s stock. For purposes of this
Section 8, the Option shall be deemed assumed if, following the Change in Control, the Option confers the right to purchase in accordance with its terms and conditions, for each share of Stock subject to the Option immediately prior to the
Change in Control, the consideration (whether stock, cash or other securities or property) to which a holder of a share of Stock on the effective date of the Change in Control was entitled. In the event the Acquiring Corporation elects not to assume
the Company’s rights and obligations under the Option Agreement or substitute for the Option in connection with the Change in Control, and provided that the Optionee’s Service has not terminated prior to such date, the Vested Ratio shall
be deemed to be 1/1 and all shares acquired upon exercise of the Option shall be Vested Shares for purposes of Section 11 as of the date ten (10) days prior to the date of the Change in Control. Any vesting of the Option that was
permissible solely by reason of this Section 8 shall be conditioned upon the consummation of the Change in Control. The Option shall terminate and cease to be outstanding effective as of the date of the Change in Control to the extent that the
Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control. Notwithstanding the foregoing, shares

 
acquired upon exercise of the Option prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to
all applicable provisions of this Option Agreement except as otherwise provided herein. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the Option immediately prior to an Ownership Change Event
constituting a Change in Control is the surviving or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or
by other corporations that are members of an affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the Option shall not terminate unless the Board otherwise
provides in its discretion. 
  

	 	9.	 ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. 

In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or similar change
in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise Price and class of shares of stock subject to the Option. If a majority of the shares which are of the same class as the shares that are subject
to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the “New Shares”), the Board may unilaterally amend the
Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option Shares and the Exercise Price shall be adjusted in a fair and equitable manner, as determined by the Board, in its discretion.
Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 9 shall be rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par
value, if any, of the stock subject to the Option. The adjustments determined by the Board pursuant to this Section 9 shall be final, binding and conclusive. 
  

	 	10.	 RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT. 

The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a
certificate for the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or
other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 9. If the Optionee is an Employee, the Optionee understands and acknowledges that, except as otherwise provided in a separate,
written employment agreement between a Participating Company and the Optionee, the Optionee’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Optionee any right to continue
in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Optionee’s Service as an Employee or Consultant, as the case may be, at any time. 

 

	 	11.	 RIGHT OF FIRST REFUSAL. 

11.1 Grant of Right of First Refusal. Except as provided in Section 11.7 below, in the
event the Optionee, the Optionee’s legal representative, or other holder of shares 

 
acquired upon exercise of the Option proposes to sell, exchange, transfer, pledge, or otherwise dispose of any shares acquired upon exercise of the Option (the “Transfer
Shares”) to any person or entity, including, without limitation, any stockholder of a Participating Company, the Company shall have the right to repurchase the Transfer Shares under the terms and subject to the conditions set
forth in this Section 11 (the “Right of First Refusal”). 
 11.2 Notice of Proposed Transfer. Prior to any proposed transfer of the Transfer Shares, the Optionee shall deliver written notice (the “Transfer
Notice”) to the Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the proposed transferee (the “Proposed Transferee”) and, if
the transfer is voluntary, the proposed transfer price, and containing such information necessary to show the bona fide nature of the proposed transfer. In the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be
deemed to be the Fair Market Value of the Transfer Shares, as determined by the Board in good faith. If the Optionee proposes to transfer any Transfer Shares to more than one Proposed Transferee, the Optionee shall provide a separate Transfer Notice
for the proposed transfer to each Proposed Transferee. The Transfer Notice shall be signed by both the Optionee and the Proposed Transferee and must constitute a binding commitment of the Optionee and the Proposed Transferee for the transfer of the
Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal. 
 11.3
Bona Fide Transfer. If the Company determines that the information provided by the Optionee in the Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Optionee
written notice of the Optionee’s failure to comply with the procedure described in this Section 11, and the Optionee shall have no right to transfer the Transfer Shares without first complying with the procedure described in this
Section 11. The Optionee shall not be permitted to transfer the Transfer Shares if the proposed transfer is not bona fide. 
 11.4 Exercise of Right of First Refusal. If the Company determines the proposed transfer to be bona fide, the Company shall have the right to purchase all, but not less than all, of the
Transfer Shares (except as the Company and the Optionee otherwise agree) at the purchase price and on the terms set forth in the Transfer Notice by delivery to the Optionee of a notice of exercise of the Right of First Refusal within thirty
(30) days after the date the Transfer Notice is delivered to the Company. The Company’s exercise or failure to exercise the Right of First Refusal with respect to any proposed transfer described in a Transfer Notice shall not affect the
Company’s right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer Notice, whether or not such other Transfer Notice is issued by the Optionee or issued by a person other than the
Optionee with respect to a proposed transfer to the same Proposed Transferee. If the Company exercises the Right of First Refusal, the Company and the Optionee shall thereupon consummate the sale of the Transfer Shares to the Company on the terms
set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company (unless a longer period is offered by the Proposed Transferee); provided, however, that in the event the Transfer Notice
provides for the payment for the Transfer Shares other than in cash, the Company shall have the option of paying for the Transfer Shares by the present value cash equivalent of the consideration described in the Transfer Notice as reasonably
determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of the Optionee to any Participating Company shall be treated 

 
as payment to the Optionee in cash to the extent of the unpaid principal and any accrued interest canceled. 

11.5 Failure to Exercise Right of First Refusal. If the Company fails to exercise the Right
of First Refusal in full (or to such lesser extent as the Company and the Optionee otherwise agree) within the period specified in Section 11.4 above, the Optionee may conclude a transfer to the Proposed Transferee of the Transfer Shares on the
terms and conditions described in the Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice. The Company shall have the right to demand further assurances from
the Optionee and the Proposed Transferee (in a form satisfactory to the Company) that the transfer of the Transfer Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Transfer Shares shall be transferred
on the books of the Company until the Company has received such assurances, if so demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as
well as any subsequent proposed transfer by the Optionee, shall again be subject to the Right of First Refusal and shall require compliance by the Optionee with the procedure described in this Section 11. 

11.6 Transferees of Transfer Shares. All transferees of the Transfer Shares or any interest
therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer Shares or interest therein subject to all of the
terms and conditions of this Option Agreement, including this Section 11 providing for the Right of First Refusal with respect to any subsequent transfer. Any sale or transfer of any shares acquired upon exercise of the Option shall be void
unless the provisions of this Section 11 are met. 
 11.7 Transfers Not Subject to Right
of First Refusal. The Right of First Refusal shall not apply to any transfer or exchange of the shares acquired upon exercise of the Option if such transfer or exchange is in connection with an Ownership Change Event. If the consideration
received pursuant to such transfer or exchange consists of stock of a Participating Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of Section 11.9 below result in a termination of the Right
of First Refusal. 
 11.8 Assignment of Right of First Refusal. The Company shall
have the right to assign the Right of First Refusal at any time, whether or not there has been an attempted transfer, to one or more persons as may be selected by the Company. 

11.9 Early Termination of Right of First Refusal. The other provisions of this Option
Agreement notwithstanding, the Right of First Refusal shall terminate and be of no further force and effect upon (a) the occurrence of a Change in Control, unless the Acquiring Corporation assumes the Company’s rights and obligations under
the Option or substitutes a substantially equivalent option for the Acquiring Corporation’s stock for the Option, or (b) the existence of a public market for the class of shares subject to the Right of First Refusal. A
“public market” shall be deemed to exist if (i) such stock is listed on a national securities exchange (as that term is used in the Exchange Act) or (ii) such stock is traded on the over-the-counter
market and prices therefor are published daily on business days in a recognized financial journal. 

	 	12.	 STOCK DISTRIBUTIONS SUBJECT TO OPTION AGREEMENT. 

If, from time to time, there is any stock dividend, stock split or other change, as described in Section 9, in the character or
amount of any of the outstanding stock of the corporation the stock of which is subject to the provisions of this Option Agreement, then in such event any and all new, substituted or additional securities to which the Optionee is entitled by reason
of the Optionee’s ownership of the shares acquired upon exercise of the Option shall be immediately subject to the Right of First Refusal and any security interest held by the Company with the same force and effect as the shares subject to such
restrictions immediately before such event. 
  

	 	13.	 NOTICE OF SALES UPON DISQUALIFYING DISPOSITION. 

The Optionee shall dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement.
In addition, if the Notice designates this Option as an Incentive Stock Option, the Optionee shall (a) promptly notify the Chief Financial Officer of the Company if the Optionee disposes of any of the shares acquired pursuant to the
Option within one (1) year after the date the Optionee exercises all or part of the Option or within two (2) years after the Date of Option Grant and (b) provide the Company with a description of the circumstances of such disposition.
Until such time as the Optionee disposes of such shares in a manner consistent with the provisions of this Option Agreement, unless otherwise expressly authorized by the Company, the Optionee shall hold all shares acquired pursuant to the Option in
the Optionee’s name (and not in the name of any nominee) for the one-year period immediately after the exercise of the Option and the two-year period immediately after Date of Option Grant. At any time during the one-year or two-year periods
set forth above, the Company may place a legend on any certificate representing shares acquired pursuant to the Option requesting the transfer agent for the Company’s stock to notify the Company of any such transfers. The obligation of the
Optionee to notify the Company of any such transfer shall continue notwithstanding that a legend has been placed on the certificate pursuant to the preceding sentence. 
  

	 	14.	 LEGENDS. 

 The Company may at any time place legends referencing the Right of First Refusal and any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock
subject to the provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in
order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following: 

14.1 “THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE ACT, OR
THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH 

 
SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.” 

14.2 “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF FIRST REFUSAL OPTION IN
FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION.”

 14.3 If the Notice designates this Option as an Incentive Stock Option: “THE SHARES EVIDENCED BY THIS CERTIFICATE WERE
ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON EXERCISE OF AN INCENTIVE STOCK OPTION AS DEFINED IN SECTION 422 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (“ISO”). IN ORDER TO OBTAIN THE PREFERENTIAL TAX TREATMENT
AFFORDED TO ISOs, THE SHARES SHOULD NOT BE TRANSFERRED PRIOR TO [INSERT LATER OF TWO YEARS AFTER THE DATE OF OPTION GRANT OR ONE YEAR AFTER THE DATE OF EXERCISE HERE]. SHOULD THE REGISTERED HOLDER ELECT TO TRANSFER ANY OF THE SHARES
PRIOR TO THIS DATE AND FOREGO ISO TAX TREATMENT, THE TRANSFER AGENT FOR THE SHARES SHALL NOTIFY THE CORPORATION IMMEDIATELY. THE REGISTERED HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE INCENTIVE STOCK OPTION IN THE REGISTERED HOLDER’S NAME
(AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE OR UNTIL TRANSFERRED AS DESCRIBED ABOVE.” 
  

	 	15.	 LOCK-UP AGREEMENT. 

 The Optionee hereby agrees that in the event of any underwritten public offering of stock, including an initial public offering of stock, made by the Company pursuant to an effective registration
statement filed under the Securities Act, the Optionee shall not offer, sell, contract to sell, pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to
acquire stock of the Company for such period of time from and after the effective date of such registration statement as may be established by the underwriter for such public offering; provided, however, that such period of time shall not exceed one
hundred eighty (180) days from the effective date of the registration statement to be filed in connection with such public offering. The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act.

  

	 	16.	 RESTRICTIONS ON TRANSFER OF SHARES. 

 No shares acquired upon exercise of the Option may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee or agent of the Optionee), assigned, pledged, hypothecated or
otherwise disposed of, including by operation of law, in any manner which violates any of the provisions of this Option Agreement and any such attempted disposition shall be void. The Company shall not be required (a) to transfer on its books
any shares which will have been transferred in violation of any of the provisions set forth in this Option Agreement or 

 
(b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares will have been so transferred. 

 

	 	17.	 MISCELLANEOUS PROVISIONS. 

17.1 Binding Effect. Subject to the restrictions on transfer set forth herein, this Option
Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns. 

17.2 Termination or Amendment. The Board may terminate or amend the Plan or the Option at any time;
provided, however, that except as provided in Section 8 in connection with a Change in Control, no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee unless such
termination or amendment is necessary to comply with any applicable law or government regulation or is required to enable the Option, if designated an Incentive Stock Option in the Notice, to qualify as an Incentive Stock Option. No amendment or
addition to this Option Agreement shall be effective unless in writing. 
 17.3 Notices.
Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given (except to the extent that this Option Agreement provides for effectiveness only upon actual receipt of such notice) upon personal delivery or
upon deposit in the United States Post Office, by registered or certified mail, with postage and fees prepaid, addressed to the other party at the address shown below that party’s signature or at such other address as such party may designate
in writing from time to time to the other party. 
 17.4 Integrated Agreement. The Notice,
this Option Agreement and the Plan constitute the entire understanding and agreement of the Optionee and the Participating Company Group with respect to the subject matter contained herein or therein and supersedes any prior agreements,
understandings, restrictions, representations, or warranties among the Optionee and the Participating Company Group with respect to such subject matter other than those as set forth or provided for herein or therein. To the extent contemplated
herein or therein, the provisions of the Notice and the Option Agreement shall survive any exercise of the Option and shall remain in full force and effect. 

17.5 Applicable Law. This Option Agreement shall be governed by the laws of the State of California
as such laws are applied to agreements between California residents entered into and to be performed entirely within the State of California.

 Exhibit 10.03 
 AMENDED AND RESTATED 2006 STOCK OPTION PLAN, AS AMENDED, 
 OF

 VOCERA COMMUNICATIONS, INC. 

1. Adoption and Purpose of the Plan. This stock option plan, to be known as the “Vocera Communications, Inc.
2006 Stock Option Plan” (but referred to herein as the “Plan”) has been adopted by the Board of Directors (the “Board”) of Vocera Communications, Inc., a Delaware corporation (the “Company”),
and is subject to the approval of its stockholders pursuant to Section 7 below. The purpose of this Plan is to advance the interests of the Company and its shareholders by enabling the Company and its Affiliates to attract and retain qualified
directors, officers, employees and certain independent contractors, consultants and advisors by providing them with an opportunity for investment in the Company. The options that may be granted hereunder (“Options”) represent the
right by the grantee thereof (each, including any permitted transferee pursuant to Section 6.7 below, an “Optionee”) to acquire shares of the Company’s Common Stock (“Shares” which if acquired pursuant to
the exercise of an Option will be referred to as “Option Shares”) subject to the terms and conditions of this Plan and a written agreement between the Company and the Optionee to evidence each such Option (an “Option
Agreement”). 
 2. Certain Definitions. The defined terms set forth in Exhibit A attached
hereto and incorporated herein (together with other capitalized terms defined elsewhere in this Plan) will govern the interpretation of this Plan. 
 3. Eligibility. The Company may grant Options under this Plan only to (i) persons who, at the time of such grant, are directors, officers or employees of the Company and/or any of its
Subsidiaries or Affiliates, and (ii) natural persons who, at the time of such grant, are independent contractors, consultants or advisors to the Company and/or any of its Subsidiaries or Affiliates and who perform bona fide services on
its or their behalf other than in connection with capital raising transactions (collectively, “Eligible Participants”). No person will be an Eligible Participant following his or her Termination of Eligibility Status and no Option
may be granted to any person other than an Eligible Participant. There is no limitation on the number of Options that may be granted to an Eligible Participant. 

4. Option Pool; Shares Reserved for Options. In no event (except as provided in Section 8) will the Company
issue, in the aggregate, more than 31,352,984 Shares (the “Option Pool”) pursuant to the exercise of all Options granted under this Plan (including the exercise of ISOs), inclusive of those Option Shares that may be reacquired by
the Company by repurchase or otherwise. At all times while Options granted under this Plan are outstanding, the Company will reserve for issuance for the purposes hereof a sufficient number of authorized and unissued Shares to fully satisfy the
Company’s obligations under all such outstanding Options. 
 5. Administration. This Plan will be
administered and interpreted by the Board, or by a committee consisting of two or more members of the Board, appointed by the Board for such purpose (the Board, or such committee, referred to herein as the “Administrator”). Subject
to the express terms and conditions hereof, the Administrator is authorized to prescribe, amend and rescind rules and regulations relating to this Plan, and to make all other determinations 

  
 1 

 
necessary or advisable for its administration and interpretation. Specifically, the Administrator will have full and final authority in its discretion, subject to the specific limitations on that
discretion as are set forth herein and in the Certificate of Incorporation and Bylaws of the Company, at any time: 
 (a) to select and approve the Eligible Participants to whom Options will be granted from time to time hereunder; 

(b) to determine the Fair Market Value of the Shares as of the Grant Date for any Option that is granted
hereunder; 
 (c) with respect to each Option it decides to grant, to determine the terms and
conditions of that Option, to be set forth in the Option Agreement evidencing that Option (the form of which also being subject to approval by the Administrator), which may vary from the “default” terms and conditions set forth in
Section 6 below, except to the extent otherwise provided in this Plan, including, without limitation, as follows (provided that the Administrator may waive compliance with any of the following in any particular situation to the extent that such
limitation was based on seeking to comply with applicable securities law and adherence to same is not required to so comply, as determined by the Administrator after consultation with counsel to the Company): 

(i) the total number of Option Shares that may be acquired by the Optionee pursuant to the Option;

 (ii) if the Option satisfies the conditions under Section 422(b) of the Code, whether the
Option will be treated as an ISO to the maximum extent permissible under the Code; 
 (iii) the
per share purchase price to be paid to the Company by the Optionee to acquire the Option Shares issuable upon exercise of the Option (the “Option Price”), provided that the Option Price will not be less than 100%, unless the
Optionee is a 10% Shareholder, in which case the Option Price will not be less than 110% of such Fair Market Value in the case of ISOs; 
 (iv) the maximum period or term during which the Option will be exercisable (the “Option Term”), provided that in no event may the Option Term be longer than 10 years from the
Grant Date; 
 (v) the maximum period following any Termination of Eligibility Status, whether
resulting from an Optionee’s death, Disability or any other reason, during which period (the “Grace Period”) the Option will be exercisable, subject to Vesting and to the expiration of the Option Term, provided that in
no event may the Administrator designate a Grace Period that is shorter than six (6) months after such Termination of Eligibility Status by reason of the Optionee’s death or Disability, or thirty (30) days after such Termination of
Eligibility for any other reason, except in the event of a Termination for Cause, in which case no Grace Period will be required (i.e., the Option would terminate immediately); 

  
 2 

 (vi) whether to accept a promissory note or other form of
legal consideration in addition to cash as payment of all or a portion of the Option Price and/or Tax Withholding Liability to be paid by the Optionee upon the exercise of an Option granted hereunder; 

(vii) the conditions (e.g., the passage of time or the occurrence of events), if any, that must be
satisfied prior to the vesting of the right to exercise all or specified portions of an Option (such portions being described as the number of Option Shares, or the percentage of the total number of Option Shares that may be acquired by the Optionee
pursuant to the Option; the vested portion being referred to as a “Vested Option” and the unvested portion being referred to as an “Unvested Option”); and 

(viii) in addition, or as an alternative, to imposing conditions on the right to exercise an Option as
provided in Section 5(c)(vii) above, whether any portion of the Option Shares acquired by an Optionee upon exercise of an Option will be subject to repurchase by the Company or its assigns pursuant to Section 6.8(c) below at the Option
Price paid for such Shares or at some other price that may be less than the Fair Market Value of such Shares (such Shares, if subject to repurchase at less than Fair Market Value, being referred to as “Unvested Shares”) following a
Termination of Eligibility Status or other designated event, and the conditions (e.g., the passage of time or the occurrence of events), if any, that must be satisfied for such Shares to be no longer subject to such right of repurchase at less than
Fair Market Value (such Shares being referred to as “Vested Shares”); and 
 (d)
to delegate all or a portion of the Administrator’s authority under Sections 5(a), (b) and (c) above to one or more members of the Board who also are executive officers of the Company, subject to such restrictions and limitations as
the Administrator may decide to impose on such delegation. 
 6. Default Terms and Conditions of Option
Agreements. Unless otherwise expressly provided in an Option Agreement based on the Administrator’s determination pursuant to Section 5(c) above, the following terms and conditions will be deemed to apply to each Option as if expressly
set forth in the Option Agreement: 
 6.1 ISO. No portion of an Option will be treated as
an ISO unless treatment as an ISO is expressly provided for in an Option Agreement and such portion of the Option satisfies the conditions of Section 422(b) of the Code. 

6.2 Option Term. The Option Term will be for a period of ten (10) years beginning on the Grant
Date, except that in the case of an ISO granted to a 10% Shareholder, the Option Term will be for a period of five (5) years beginning on the Grant Date. 

6.3 Grace Periods. Following a Termination of Eligibility Status: 

(a) the Grace Period will be ninety (90) days, unless the Termination of Eligibility Status is a
result of a Termination for Cause or the death or Disability of the Optionee; 

  
 3 

 (b) the Grace Period will be twelve (12) months if the
Termination of Eligibility Status is a result of the death or Disability of the Optionee; and 

(c) the Option will terminate, and there will be no Grace Period, effective immediately as of the date and
time of a Termination for Cause of the Optionee, regardless of whether the Option is Vested or Unvested. 
 The Company will
have no obligation to inform an Optionee as to when a relevant Grace Period will terminate; it will be the responsibility of the Optionee to determine the dates of the relevant Grace Period. 

6.4 Vesting. The Option will be exercisable in whole or in part prior to the Optionee’s
Termination of Eligibility Status. The Option will be exercisable following a Termination of Eligibility Status only to purchase such portion of the Shares issuable upon exercise of the Option as would represent Vested Shares upon issuance. The
Shares issued or issuable upon exercise of the Option initially will be deemed Unvested Shares, but portions of such aggregate number of Shares issued or issuable upon exercise of the Option will become Vested Shares on the following schedule:
Twenty-five percent (25%) of the aggregate number of such Shares will become Vested Shares as of the first anniversary of the “Vesting Start Date” specified in the Option Agreement (which may be earlier but may not be later than the
Grant Date specified therein) and the balance of such Shares will become Vested Shares pro rata monthly (based on monthly anniversary dates of the day of the month of the Vesting Start Date) over the three year period immediately following such
first anniversary; provided that there will be no further vesting once the Optionee suffers a Termination of Eligibility Status and provided further that additional vesting will be suspended during any period while the Optionee is on a
leave of absence from the Company or its Subsidiaries or Affiliates, as determined by the Administrator. If at any time there are both outstanding Shares issued upon exercise of the Option and Shares not yet issued but issuable upon exercise of the
Option, then the portion of Shares constituting Vested Shares shall be allocated to the maximum extent possible to the outstanding Shares as opposed to the Shares not yet issued but issuable upon exercise of the Option. 

6.5 Exercise of the Option; Issuance of Share Certificate. 

(a) The Option may be exercised by giving written notice thereof to the Company, on such form as may be
specified by the Administrator, but in any event stating: the Optionee’s intention to exercise the Option; the date of exercise; the number of full Option Shares to be purchased (which number will be no less than one hundred (100) Shares,
without regard to adjustments to the number of Shares subject to the Option pursuant to Section 8 below, or, if less, all of the remaining Shares subject to the Option); the amount and form of payment of the Option Price; and such assurances of
the Optionee’s investment intent as the Company may require to ensure that the transaction complies in all respects with the requirements of the 1933 Act and other applicable securities laws. The notice of exercise will be signed by the person
or persons exercising the Option. In the event that the Option is being exercised by the representative of the Optionee, the notice will be accompanied by proof satisfactory to the Company of the representative’s right to exercise the Option.
The notice of exercise will be accompanied by full payment of the Option Price for the number of Option Shares to be 

  
 4 

 
purchased, in United States dollars, in cash, by check made payable to the Company, or by delivery of such other form of payment (if any) as may be approved by the Administrator in the particular
case. 
 (b) To the extent required by applicable federal, state, local or foreign law, and as a
condition to the Company’s obligation to issue any Shares upon the exercise of the Option in full or in part, the Optionee will make arrangements satisfactory to the Company for the payment of any applicable Tax Withholding Liability that may
arise by reason of or in connection with such exercise. Such arrangements may include, in the Company’s sole discretion, that the Optionee tender to the Company the amount of such Tax Withholding Liability, in cash, by check made payable to the
Company, or by delivery of such other form of payment (if any) as may be approved by the Administrator in the particular case. 
 (c) After receiving a proper notice of exercise and payment of the applicable Option Price and Tax Withholding Liability, the Company will cause to be issued a certificate or certificates for the Option
Shares as to which the Option has been exercised, registered in the name of the person rightfully exercising the Option and the Company will cause such certificate or certificates to be delivered to such person or into escrow as provided in
Section 6.8(e), below. 
 6.6 Compliance with Law. Notwithstanding any other
provision of this Plan, Options may be granted pursuant to this Plan, and Option Shares may be issued pursuant to the exercise thereof by an Optionee, only after and on the condition that there has been compliance with all applicable federal and
state securities laws. The Company will not be required to list, register or qualify any Option Shares upon any securities exchange, under any applicable state, federal or foreign law or regulation, or with the Securities and Exchange Commission or
any state agency, or secure the consent or approval of any governmental regulatory authority, except that if at any time the Board determines, in its discretion, that such listing, registration or qualification of the Option Shares, or any such
consent or approval, is necessary or desirable as a condition of or in connection with the exercise of an Option and the purchase of Option Shares thereunder, that Option may not be exercised, in whole or in part, unless and until such listing,
registration, qualification, consent or approval is effected or obtained free of any conditions that are not acceptable to the Board, in its discretion. However, the Company will seek to register or qualify with, or as may be provided by applicable
local law, file for and secure an exemption from such registration or qualification requirements from, the applicable securities administrator and other officials of each state in which an Eligible Participant would be granted an Option hereunder
prior to such grant. 
 6.7 Restrictions on Transfer. 

(a) Restrictions on Options Transferability. 

(i) No ISO will be transferable by an Optionee other than (x) by will or the laws of descent and
distribution; or (y) with the prior written consent of the Company, to a trust if the Optionee is considered the sole beneficial owner of the Option for tax purposes and under applicable law while it is held in trust. 

(ii) Except as otherwise determined by the Board, no Option that is not an ISO will be
transferable other than (x) by will or the laws of descent and distribution; (y) with the prior written consent of the Company, to a trust if the Optionee is considered the sole beneficial owner of the Option for tax purposes and under applicable
law while it is held in trust; or (z) to such further extent as permitted by Section 260.140.41(c) of Title 10 of the California Code of Regulations, except as otherwise provided in the Option Agreement therefor. 

  
 5 

 (b) Prohibited Transfers. No Holder of any Option
Shares may Transfer such Shares, or any interest therein: (i) except as expressly provided in this Plan; and (ii) other than in full compliance with all applicable securities laws and any applicable restrictions on Transfer provided in the
Company’s Certificate of Incorporation and/or Bylaws, which will be deemed incorporated by reference into this Plan. All Transfers of Option Shares not complying with the specific limitations and conditions set forth in this Section 6.7
and Section 6.8 below are expressly prohibited. Any prohibited Transfer is void and of no effect, and no purported transferee in connection therewith will be recognized as a Holder of Option Shares for any purpose whatsoever. Should such a
Transfer purport to occur, the Company may refuse to carry out the Transfer on its books, attempt to set aside the Transfer, enforce any undertakings or rights under this Plan, or exercise any other legal or equitable remedy. Without the prior
written consent of the Company, no Unvested Shares will be transferable by an Optionee other than by will or the laws of descent and distribution. 

(c) Permitted Transfers. In the case of a Permitted Transfer, the rights of first refusal and
purchase of the Company set forth in Sections 6.8(a) and 6.8(b) below will not apply to the particular Transfer constituting the Permitted Transfer. For such purposes, a “Permitted Transfer” means a Transfer by a Holder of Option
Shares that is approved in writing by the Company as a Permitted Transfer for the purposes of this Plan. 
 (d) Conditions to Transfer. It will be a condition to any Transfer (whether as a Permitted Transfer, as a Transfer referred to in Section 6.8(a)(iv) or otherwise) of any Option Shares that:

 (i) the transferee of the Shares will execute such documents as the Company may reasonably
require to ensure that the Company’s rights under this Plan, and any applicable Option Agreement, are adequately protected with respect to such Shares, including, without limitation, the transferee’s agreement to be bound by all of the
terms and conditions of this Plan (such as transfer restrictions, market standoff provisions and rights of first refusal on transfer) and such Agreement, as if he or she were the original Holder of such Shares; and 

(ii) the Company is satisfied that such Transfer complies in all respects with the requirements imposed
by applicable state and federal securities laws and regulations. 
 (e) Market Standoff.
If in connection with any public offering of securities of the Company (or any Successor Entity), the underwriter or underwriters managing such offering so requests, then each Optionee and each Holder of Option Shares will agree to not sell or
otherwise Transfer any such Shares (other than Shares if and to the extent included in such underwriting) without the prior written consent of such underwriter, for such period of time as may be requested by the underwriter commencing on the
effective date of the registration statement filed with the Securities and Exchange Commission in connection with such offering. By accepting an Option and/or Option Shares under this Plan, the Optionee will be deemed to agree to execute such
documents to further evidence such market standoff agreement as may be requested by such underwriter. 

  
 6 

 6.8 Rights of Purchase and First Refusal. The Company
will have the following rights of purchase and first refusal with respect to Option Shares: 

(a) Right of First Refusal. If any Holder proposes to Transfer any Option Shares prior to a
Qualified Initial Public Offering, other than in the case of a Permitted Transfer pursuant to Section 6.7(c) above or an Involuntary or Donative Transfer subject to Section 6.8(b) below, the Company will have an assignable right of first
refusal to purchase such Shares on the terms and conditions set out in this Section 6.8(a). If the Company (or its assignee) elects to exercise all or part of such right, it will do so with respect to any particular Transfer of Shares in the
following manner: 
 (i) Before any such Transfer, the Holder proposing to Transfer such Shares
will deliver a notice of proposed Transfer (a “Proposed Transfer Notice”) to the Company stating: the number of Option Shares that the Holder proposes to Transfer and the Holder’s bona fide intention to Transfer such
Shares; the names and addresses of the Holder, the proposed transferee and subsequently such other information regarding such transferee as the Company reasonably requests; the manner and date of such proposed Transfer; and the bona fide cash
price and/or other consideration (and the Holder’s estimate of the fair market value thereof) per share, if any, that such Transferee has offered to pay Holder for such Shares (the “Offered Price”) as well as such other terms,
including payment terms, and conditions, if any, as were included in such offer (the “Offered Terms”). 
 (ii) The Company (or its assignee) may exercise its right of first refusal under this Section 6.8(a) at any time not more than twenty (20) days after the Company has received the Proposed
Transfer Notice with respect to such Shares. If the Company (or its assignee) elects to exercise such purchase rights it will do so by delivering to the Holder of such Shares a notice of such election, specifying the number of Shares to be purchased
and a closing date that is no more than thirty (30) days after receipt of the Proposed Transfer Notice (or such later date as the transferee may have offered or on which the Transfer is otherwise scheduled to occur). 

(iii) At the closing of the sale of the Shares to the Company (or its assignee), to be held at its
principal executive offices, the Company (or its assignee) will pay the Holder of the Shares, in cash, the purchase price equal to the Offered Price (provided, however, that if any of the Shares being transferred are Unvested Shares, the
purchase price for the Unvested Shares will equal the Option Price per Share paid upon the exercise of the Option to purchase such Unvested Shares), subject to an appropriate adjustment as determined in good faith by the Company to take into account
any deferred payment terms that were included in the Offered Terms, except in the case of a Transfer of Option Shares without consideration; provided that if the Offered Price includes any non-cash consideration, the value thereof for
purposes of this Section 6.8(a) will be determined in good faith by the Board. 
 (iv) If
the Company (including its assignees) fails or refuses to exercise its rights under this Section 6.8(a) with respect to any Shares that are the subject of any Proposed Transfer Notice, then the Holder will have the right to Transfer such Shares
to the transferee named in such Notice at the Offered Price and upon such Offered Terms as were set 

  
 7 

 
forth in such Notice; provided that such Transfer must be completed within ninety (90) days after the Company has received the Proposed Transfer Notice with respect to such Shares.

 (b) Following an Involuntary or Donative Transfer. Following any Involuntary Transfer
or Donative Transfer (other than a Permitted Transfer) of Option Shares (the “Transferred Shares”) that occurs either prior to a Qualified Initial Public Offering or represents a Transfer of Unvested Shares at any time, the Company
will have the assignable right to purchase from the transferee of the Transferred Shares (“Transferee”) all or a portion of such Shares for a purchase price that is equal to the Fair Market Value of those Shares as of the date of
such Transfer (provided, however, that if any of the Shares being transferred are Unvested Shares, the purchase price for the Unvested Shares will equal the Option Price per Share paid upon the exercise of the Option to purchase such Unvested
Shares). If the Company (or its assignee) elects to exercise such right, it will do so in the following manner: 
 (i) Promptly after such Transfer, the transferor of the Transferred Shares will deliver, or will cause the Transferee to deliver, a notice (a “Completed Transfer Notice”) to the Company
stating: the number of Transferred Shares; the names and addresses of the transferor and the Transferee, and subsequently such other information regarding the Transferee as the Company reasonably requests; and the manner, circumstances and date of
such Transfer. 
 (ii) The Company (or its assignee) may exercise its purchase rights under this
Section 6.8(b) at any time not more than ninety (90) days after the Company has received the Completed Transfer Notice with respect to the Transferred Shares. If the Company (or its assignee) elects to exercise such purchase rights it will
do so by delivering to the Transferee a notice of such election, specifying the number of Transferred Shares to be purchased and a closing date that is no more than sixty (60) days after the giving of such notice. 

(iii) At such closing, to be held at the Company’s principal executive offices, the Company (or its
assignee) will pay the Transferee the purchase price specified in this Section 6.8(b). 

(c) Following a Termination of Eligibility Status. Following any Termination of Eligibility Status
of the original Holder of any Option Shares, the Company will have the assignable right (but not the obligation) to purchase from the current Holder of those Option Shares to the extent constituting Unvested Shares, all or a portion (as designated
by the Company) of such Unvested Shares for a purchase price that is equal to the Option Price per Share paid for those Shares upon the exercise of the Option. Such right will be exercisable in the following manner: 

(i) The Company (or its assignee) may exercise its right of repurchase under this Section 6.8(c) at
any time not more than ninety (90) days after the effective date of such Termination of Eligibility Status (or in the case of Shares issued upon the exercise of Options after such Termination of Eligibility Status, a period of ninety
(90) days after the date of the exercise). If the Company (or its assignee) elects to exercise such purchase rights it will do so by delivering to the Holder of such Shares a notice of such election, specifying the number of Unvested Shares to
be purchased and a closing date that is within such ninety (90) day period, 

  
 8 

 
provided that if the Holder of the Shares is not an employee of the Company or any of its Subsidiaries or Affiliates, or is an officer, director or affiliate thereof, the Option Agreement
may provide that the period during which such purchase of the Shares must take place may be longer than ninety (90) days. 
 (ii) At such closing, the Company (or its assignee) will pay the Holder of the Shares, the purchase price, as specified in this Section 6.8(c), in cash, or by cancellation of indebtedness to the
Company, if any, incurred by the original Holder of the Option Shares to purchase such Unvested Shares, or both, at a closing to be held at the Company’s principal executive offices on the date specified in such notice, provided that if
the Holder of the Shares is not an employee of the Company or any of its Subsidiaries or Affiliates, or is an officer, director or affiliate thereof, the Option Agreement may provide that the purchase price may be paid, in whole or in part, with a
promissory note from the Company (or its assignee). 
 (d) Escrow. For purposes of
facilitating the enforcement of the restrictions on Transfer, rights of first refusal and rights of repurchase set forth in this Plan or in any Option Agreement, the Administrator may, at its discretion, require the Holder of Option Shares to
deliver the certificate(s) for such Shares with a stock power executed by him or her and by his or her spouse (if required for Transfer), in blank, to the Secretary of the Company or his or her designee, to hold said certificate(s) and stock
power(s) in escrow and to take all such actions and to effectuate all such Transfers and/or releases as are in accordance with the terms of this Plan. The certificates may be held in escrow so long as the Option Shares whose ownership they evidence
are subject to any right of repurchase or first refusal under this Plan or under an Option Agreement, and will be released by the escrow holder to an Optionee (or to any permitted transferee of the Optionee) when they are no longer subject to any
transfer restrictions, right of repurchase or right of first refusal under this Plan or under the Option Agreement. Each Optionee, by exercising an Option, thereby acknowledges that the Secretary of the Company (or his or her designee) is so
appointed as the escrow holder with the foregoing authorities as a material inducement to the grant of an Option under this Plan, that the appointment is coupled with an interest, and that it accordingly will be irrevocable. The escrow holder will
not be liable to any party to an Option Agreement (or to any other party) for any actions or omissions unless the escrow holder is grossly negligent relative thereto. The escrow holder may rely upon any letter, notice or other document executed by
any signature purported to be genuine. 
 6.9 Change of Control Transactions. In the event
of a Change of Control Transaction, the Company shall endeavor to cause the Successor Entity in such transaction either to assume all of the Options which have been granted hereunder and which are outstanding as of the consummation of such
transaction (“Closing”), or to issue (or cause to be issued) in substitution thereof comparable options of such Successor Entity (or of its parent or its Subsidiary). In each case, each Option Agreement automatically will be deemed
amended to conform to any such assumption or substitution. If the Successor Entity is unwilling to either assume such Options or grant comparable options in substitution for such Options, on terms that are acceptable to the Company as determined by
the Board in the exercise of its discretion, then the Board may cancel all outstanding Options, and terminate this Plan, effective as of the Closing, provided that it will notify all Optionees of the proposed Change of Control Transaction a
reasonable amount of time prior to the Closing so that each Optionee will be given the 

  
 9 

 
opportunity to exercise his or her Option prior to the Closing, treating all shares issued upon such exercise as Vested Shares conditioned on the Closing. For purposes of this Section 6.9,
the term “Change of Control Transaction” means a Business Combination in which (x) less than fifty percent (50%) of the outstanding voting securities of the Successor Entity immediately following the Closing of the
Business Combination transaction are beneficially held by those persons and entities who beneficially held the voting securities of the Company immediately prior to such transaction as a result of or in exchange for such voting securities of the
Company held immediately prior to such transaction; or (b) an existing shareholder (including its Affiliates) that held less than 50% of the outstanding voting securities of the Company prior to such transaction succeeds to ownership of more
than 50% of the outstanding voting securities of the Company as a result of the transaction; the term “Business Combination” means a transaction or series of related transactions consummated within any period of ninety
(90) days resulting in (i) the sale of all or substantially all of the assets of the Company, or (ii) a merger or consolidation or other reorganization in which the Company or a Subsidiary is a party. 

6.10 Securities Law Matters; Investment Intent. By accepting an Option and/or Option Shares under
this Plan, the Optionee will be deemed to represent, warrant and agree that, unless a registration statement is in effect with respect to the offer and sale of Option Shares: (i) neither the Option nor any such Shares will be freely tradable
and must be held indefinitely unless such Option and such Shares are either registered under the 1933 Act or an exemption from such registration is available; (ii) the Company is under no obligation to register the Option or any such Shares;
(iii) upon exercise of the Option, the Optionee will purchase the Option Shares for his or her own account and not with a view to distribution within the meaning of the 1933 Act, other than as may be effected in compliance with the 1933 Act and
the rules and regulations promulgated thereunder; (iv) no one else will have any beneficial interest in the Option Shares; (v) the Optionee has no present intention of disposing of the Option Shares at any particular time; and
(vi) neither the Option nor the Shares have been qualified under the securities laws of any state and may only be offered and sold pursuant to an exception from qualification under applicable state securities laws. 

6.11 Stock Certificates; Legends. Certificates representing Option Shares will bear all legends
required by law and necessary or appropriate in the Administrator’s discretion to effectuate the provisions of this Plan and of the applicable Option Agreement. The Company may place a “stop transfer” order against Option Shares until
full compliance with all restrictions and conditions set forth in this Plan, in any applicable Option Agreement and in the legends referred to in this Section 6.11. 

6.12 Notices. Any notice to be given to the Company under the terms of an Option Agreement will be
addressed to the Company at its principal executive office, Attention: Corporate Secretary, or at such other address as the Company may designate in writing. Any notice to be given to an Optionee will be addressed to him or her at the address
provided to the Company by the Optionee. Any such notice will be deemed to have been duly given if and when enclosed in a properly sealed envelope, addressed as aforesaid, deposited, postage prepaid, in a post office or branch post office regularly
maintained by the local postal authority. 
 6.13 Other Provisions. Each Option Agreement
may contain such other terms, provisions and conditions, including restrictions on the Transfer of Option Shares, and rights of 

  
 10 

 
the Company to repurchase such Shares, not inconsistent with this Plan and applicable law, as may be determined by the Administrator in its sole discretion. 

6.14 Specific Performance. Under those circumstances in which the Company chooses to timely
exercise its rights to repurchase Option Shares as provided herein or in any Option Agreement, the Company will be entitled to receive such Shares in specie in order to have the same available for future issuance without dilution of the
holdings of other shareholders of the Company. By accepting Option Shares, the Holder thereof therefore acknowledges and agrees that money damages will be inadequate to compensate the Company and its shareholders if such a repurchase is not
completed as contemplated hereunder and that the Company will, in such case, be entitled to a decree of specific performance of the terms hereof or to an injunction restraining such holder (or such Holder’s personal representative) from
violating this Plan or the relevant Option Agreement, in addition to any other remedies that may be available to the Company at law or in equity. 
 7. Term of the Plan. This Plan will become effective on the date of its adoption by the Board, provided that this Plan is approved by the shareholders of the Company (excluding Option Shares
issued by the Company pursuant to the exercise of Options granted under this Plan) within 12 months before or after that date. If this Plan is not so approved by the shareholders of the Company within that 12-month period of time, any Options
granted under this Plan will be rescinded and will be void. This Plan will expire on the tenth (10th) anniversary of the date of its adoption by the Board or its approval by the shareholders of the Company, whichever is earlier, unless it is
terminated earlier pursuant to Section 11 of this Plan, after which no more Options may be granted under this Plan, although all outstanding Options granted prior to such expiration or termination will remain subject to the provisions of this
Plan, and no such expiration or termination of this Plan will result in the expiration or termination of any such Option prior to the expiration or early termination of the applicable Option Term. 

8. Adjustments Upon Changes in Stock. In the event of any change in the outstanding Shares of the Company as a
result of a stock split, reverse stock split, stock bonus or distribution, recapitalization, combination or reclassification, appropriate proportionate adjustments will be made in: (i) the aggregate number of Shares that are reserved for
issuance in the Option Pool pursuant to Section 4 above, under outstanding Options or future Options granted hereunder; (ii) the Option Price and the number of Option Shares that may be acquired under each outstanding Option granted
hereunder; and (iii) other rights and matters determined on a per share basis under this Plan or any Option Agreement evidencing an outstanding Option granted hereunder. Any such adjustments will be made only by the Board, and when so made will
be effective, conclusive and binding for all purposes with respect to this Plan and all Options then outstanding. No such adjustments will be required by reason of the issuance or sale by the Company for cash or other consideration of additional
Shares or securities convertible into or exchangeable for Shares. 
 9. Modification, Extension and Renewal
of Options. Subject to the terms and conditions and within the limitations of this Plan, the Administrator may modify, extend or renew outstanding Options granted under this Plan, or accept the surrender of outstanding Options (to the extent not
theretofore exercised) and authorize the granting of new Options in substitution therefor (to the extent not theretofore exercised). Notwithstanding the foregoing, 

  
 11 

 
however, no modification of any Option will, without the consent of the Optionee, alter or impair any rights or obligations under any outstanding Option. 

10. Governing Law; Venue. The internal laws of the State of California (irrespective of its or any other
jurisdiction’s choice of law principles) will govern the validity of this Plan, the construction of its terms and the interpretation of the rights and duties of the parties hereunder and under any Option Agreement. Subject to any obligation to
arbitrate under the terms of the relevant Option Agreement, any party may seek to enforce its rights under this Plan or any Option Agreement entered into under this Plan in any court of competent jurisdiction located within the judicial district in
which the Company has its principal place of business. 
 11. Amendment and Discontinuance. The Board may
amend, suspend or discontinue this Plan at any time or from time to time; provided that no action of the Board will, without the approval of the shareholders of the Company, materially increase (other than by reason of an adjustment pursuant
to Section 8 hereof) the maximum aggregate number of Option Shares in the Option Pool, materially increase the benefits accruing to Eligible Participants, or materially modify the category of, or eligibility requirements for persons who are
Eligible Participants. However, no such action may alter or impair any Option previously granted under this Plan without the consent of the Optionee, nor may the number of Option Shares in the Option Pool be reduced to a number that is less than the
aggregate number of Option Shares (i) that may be issued pursuant to the exercise of all outstanding and unexpired Options granted hereunder, and (ii) that have been issued and are outstanding pursuant to the exercise of Options granted
hereunder. 
 12. No Shareholder Rights. No rights or privileges of a shareholder in the Company are
conferred by reason of the granting of an Option. No Optionee will become a shareholder in the Company with respect to any Option Shares unless and until the Option has been properly exercised and the Option Price fully paid as to the portion of the
Option exercised. 
 13. Copies of Plan. A copy of this Plan will be delivered to each Optionee at or
before the time he, she or it executes an Option Agreement.

 VOCERA COMMUNICATIONS, INC. 

2006 STOCK OPTION PLAN 
 STOCK OPTION AGREEMENT 
 This Stock Option Agreement (the
“Agreement”) is made and entered into as of                     , 200     (the “Grant
Date”), by and between Vocera Communications, Inc., a Delaware corporation (the “Company”), and                     
(“Optionee”). 
 NOW, THEREFORE, the parties agree as follows: 

1. Option Grant. Subject to all of the terms and conditions of this Agreement and of the Company’s 2006 Stock
Option Plan (the “Plan”), Optionee will have an option (the “Option”) to purchase shares of the Company’s Common Stock (the “Option Shares”) on the following terms: 

 

			
	Grant #:	 	 
		
	Number of Option Shares:	 	 
		
	Option Price Per Share:	 	
$                             
                                         
                                         
                             

		
	Expiration of Option Term:	 	 Ten (10) years from the Grant Date

		
	Vesting Start Date:	 	 

 In the event of any conflict between the terms of this Agreement and/or the Plan, on the
one hand, and the Notice of Grant of Stock Options and Option Agreement attached hereto as Attachment 1 (the “Notice”), on the other hand, the terms of this Agreement and/or the Plan, as the case may be, will prevail. 

The vesting schedule for the Option will be as set forth in the Notice. In the event that no vesting schedule is set
forth in the Notice and the Notice does not provide that the Option is fully vested at issue, then the Option will be subject to vesting as set forth in Section 6.4 of the Plan. Notwithstanding anything else set forth in the Notice, there will
be no further vesting once the Optionee suffers a Termination of Eligibility Status and additional vesting will be suspended during any period while the Optionee is on a leave of absence from the Company or its Subsidiaries or Affiliates, as
determined by the Administrator. It is acknowledged and agreed that any date set for “Expiration” of the Option set forth in the Notice reflects the maximum possible Option Term, but that the Option Term may be reduced as set forth in the
Plan, and the Grace Periods for exercise of the Option as set forth in the Plan will apply to the Option. 
 The
status of whether the Option will be treated as an ISO as defined in the Plan (in all events nonemployees are not eligible to receive ISOs) is as follows (check one): 
  

	 	 ̈	 The Option will be an ISO to the maximum extent permitted under the Code. 

 

	 	 ̈	 The Option will not be an ISO.

 2. Representations and Warranties of Optionee. Optionee represents
and warrants that Optionee is acquiring the Option, and will acquire any Option Shares obtained upon exercise of the Option, for investment purposes only, for Optionee’s own account, and with no view to the distribution thereof. 

3. No Employment or Independent Contractor Rights. This Agreement gives Optionee no right to be retained as an
employee of, or independent contractor to, the Company and/or its Subsidiaries or Affiliates. 
 4. Terms of
the Plan. Optionee understands that the Plan includes important terms and conditions that apply to the Option. Those terms include: important conditions to the right of Optionee to exercise the Option; important restrictions on the ability of
Optionee to transfer the Option or to Transfer any of the Option Shares received upon exercise of the Option; rights in the Company (or its assignee) to repurchase Option Shares following a Termination of Eligibility Status; and early termination of
the Option following the occurrence of certain events. OPTIONEE HAS READ THE PLAN, AGREES TO BE BOUND BY ITS TERMS, AND MAKES EACH OF THE REPRESENTATIONS REQUIRED TO BE MADE BY OPTIONEE UNDER IT. OPTIONEE FURTHER ACKNOWLEDGES THAT THE COMPANY HAS
GIVEN NO LEGAL OR TAX ADVICE CONCERNING THE OPTION AND HAS ADVISED OPTIONEE TO CONSULT WITH OPTIONEE’S OWN TAX OR FINANCIAL ADVISOR ABOUT THE TAX TREATMENT OF THE OPTION AND ITS EXERCISE. 

5. Arbitration. In the event of any dispute concerning the enforcement of this Agreement, the dispute will be
submitted to binding arbitration before a single arbitrator in accordance with the Commercial Arbitration Rules of the American Arbitration Association, provided that: (i) the arbitrator will be instructed and empowered to take whatever
steps to expedite the arbitration as he or she deems reasonable; (ii) each party will bear its own costs in connection with the arbitration, provided that the costs of the arbitrator will be borne by the party who the arbitrator
determines not to have prevailed in the matter (unless applicable law requires the Company to bear such costs in all cases, in which case the Company will bear such costs); (iii) the arbitrator’s judgment will be final and binding upon the
parties, except that it may be challenged on the grounds of fraud or gross misconduct; and (iv) the arbitration will be held in San Francisco, California. Judgment upon any verdict in arbitration may be entered in any court of competent
jurisdiction. 
 6. Miscellaneous. 

(a) Governing Law; Interpretation. This Agreement will be governed by the substantive laws of the
State of California applicable to contracts entered into and fully performed in California. The headings and captions of the Sections of this Agreement are for convenience only and in no way define, limit or extend the scope or intent of this
Agreement or any provision hereof. This Agreement will be construed as a whole, according to its fair meaning, and not in favor of or against any party, regardless of which party may have initially drafted certain provisions set forth herein.
Capitalized terms and phrases that are not otherwise defined herein will have the meanings given them in the Plan. The terms and conditions of this 

  
 2 

 
Agreement will prevail over any expressly conflicting terms and conditions in the Plan except to the extent expressly set forth in the Plan. 

(b) Assignment. This Agreement is personal to Optionee and Optionee may not assign any of
Optionee’s rights or delegate any of Optionee’s obligations hereunder without first obtaining the prior written consent of the Company, except as expressly set forth in the Plan. 

(c) Severability. In the event any provision of this Agreement or the application of any such
provision to either of the parties is held by a court of competent jurisdiction to be contrary to law, such provision will be deemed amended to the extent necessary to comply with such law, and the remaining provisions of this Agreement will remain
in full force and effect. 
 (d) Entire Agreement; Amendments. This Agreement constitutes
the final and complete expression of all of the terms of the understanding and agreement between the parties hereto with respect to the subject matter hereof, and this Agreement replaces and supersedes any and all prior or contemporaneous
negotiations, communications, understandings, obligations, commitments, agreements or contracts, whether written or oral, between the parties respecting the subject matter hereof, including, without limitation, any negotiations, understandings or
agreements with respect to participating in the equity (including options thereon) in the Company except to the extent reflected in a share certificate heretofore issued in the name of Optionee or in a fully executed written option agreement under
an established option plan with the Company. This Agreement may not be modified, amended, altered or supplemented except by means of the execution and delivery of a written instrument mutually executed by both parties. 

IN WITNESS WHEREOF, the parties have entered into this Stock Option Agreement as of the Grant Date.
