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.

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.

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.

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:

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):

1

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.
