 UNSECURED SUBORDINATED CONVERTIBLE PROMISSORY NOTE 

ZOGENIX, INC., a Delaware corporation (the “Company”), for value received,
hereby promises to pay to                              or its registered assigns (the
“Holder”), the principal amount of
                                        
Dollars ($                      ) (the “Issue Price”), together with interest on the unpaid amount thereof in
accordance with the terms hereof, from the date hereof until paid or converted in accordance with the terms of this Unsecured Subordinated Convertible Promissory Note (this “Note”). This Note is one of a series of notes (the
“Notes”) issued pursuant to that certain Note Purchase Agreement dated July 1, 2010 by and between the Company and the entities and persons listed on the Schedule of Investors thereto (the
“Agreement”), and the Holder and the Company shall be bound by all the terms, conditions and provisions of the Agreement. 
 1. Unsecured Subordinated Convertible Promissory Note. 
 1.1 Interest
Rate. The rate of interest hereunder (“Interest Rate”) shall equal eight percent (8%) per annum, and shall be computed on the basis of a 365 day year for the actual

  
 1 

 
number of days elapsed, provided that in no event shall the Interest Rate be less than the minimum rate of interest required in order to avoid the imputation of interest for federal income tax
purposes. 
 1.2 Payment. Subject to the provisions of Section 2 regarding conversion of this Note, the Issue Price
plus all accrued but previously unpaid interest thereon shall become due and payable on [Date] (“Maturity Date”). Payment shall be made at the offices of the Holder, or such other place as the Holder shall have designated to
the Company in writing, in lawful money of the United States of America. 
 1.3 Prepayment. This Note may not be prepaid
prior to the Maturity Date, in whole or in part, without the written consent of the holders constituting sixty-seven percent (67%) of the outstanding principal amount of and accrued interest on all of the Notes (the “Required
Holders”). 
 2. Conversion. 
 2.1 Automatic Conversion. In the event the Company completes, prior to the Maturity Date, a firm commitment underwritten initial public offering pursuant to an effective registration statement
filed under the Securities Act of 1933, as amended (the “Securities Act”), covering the offer and sale of the Company’s Common Stock, par value $0.001 per share (the “Common Stock”), in which the
Company receives aggregate gross proceeds of not less than Forty Million Dollars ($40,000,000), excluding the conversion of the Notes (a “Qualified IPO”), the Issue Price plus all accrued and previously unpaid interest
thereon shall be automatically converted into that number of fully paid and nonassessable shares of the Company’s Common Stock as is equal to the Issue Price plus all accrued and previously unpaid interest thereon divided by the public price
per share of the Common Stock sold in the Qualified IPO. Any fraction of a share will be rounded down to the next whole share of Common Stock. The shares of Common Stock shall be issued contemporaneously with, but in a separate transaction from, the
closing of the Qualified IPO, and shall be deemed to be “restricted securities” as further described in Section 3.6 of the Agreement. 
 2.2 Optional Conversion at Election of Holder. In the event that a Qualified IPO has not occurred prior to the Maturity Date, the Required Holders may elect, on behalf of all holders of the Notes,
to receive the following effective as of the Maturity Date: (i) the repayment of this Note in accordance with Section 1.2 above; or (ii) that number of fully paid and nonassessable shares of the Company’s Series B Preferred
Stock, par value $0.001 per share (the “Series B Preferred Stock”), as is equal to the Issue Price plus all accrued and previously unpaid interest thereon divided by $1.10 (subject to any stock splits, sub-divisions, stock
dividends, combinations and the like affecting the Series B Preferred Stock). The Company agrees to use commercially reasonable efforts to obtain the requisite approvals to authorize sufficient Series B Preferred Stock in the event of any such
conversion pursuant to this Section 2.2 or Section 2.3 below. Holder acknowledges that any such election by the Required Holders in accordance with this Section 2.2 or Section 2.3 below shall be binding upon Holder. 

2.3 Election of Holder Upon a Deemed Liquidation Event. Upon the occurrence of a Deemed Liquidation Event (as defined in the
Company’s Fourth Amended and Restated Certificate of Incorporation, as may be amended from time to time) prior to the Maturity Date, the Required Holders may elect, on behalf of all holders of the Notes, to receive the following: (i) the
repayment of this Note in accordance with Section 1.2 above; or (ii) that number of fully paid and nonassessable shares of the Company’s B Preferred Stock as is equal to the Issue Price plus all accrued and previously unpaid interest
thereon divided by $1.10 (subject to any stock splits, sub-divisions, stock dividends, combinations and the like affecting the Series B Preferred Stock). Holder 

  
 2 

 
acknowledges that any such election by the Required Holders in accordance with this Section 2.3 or Section 2.2 above shall be binding upon Holder. The Company shall provide the Holder
with written notice of a Deemed Liquidation Event at least ten (10) days prior to the occurrence of such event, which notice shall describe the material terms and conditions of such Deemed Liquidation Event. 

2.4 Termination of Rights Upon Conversion. Upon conversion of this Note, the Holder of this Note shall have no further rights
under this Note, whether or not this Note is surrendered. 
 2.5 Delivery of Stock Certificates. As promptly as
practicable after any conversion of this Note and its surrender for cancellation by the Holder, the Company, at its expense, shall issue and deliver to the Holder of this Note a certificate or certificates evidencing the number of full equity
securities issuable to Holder upon any such conversion. 
 3. Subordination. 

The Holder acknowledges that the indebtedness evidenced by this Note is subject to that certain Subordination Agreement by and among the
holders of the Notes and Oxford Finance Corporation dated as of the date hereof. 
 4. Miscellaneous. 

4.1 Limitations on Disposition. The Holder agrees not to make any disposition of this Note or any equity securities issued upon
conversion of this Note (the “Securities”), unless and until (i) the transferee has agreed in writing for the benefit of the Company to be bound by this Section 4.1 and the other provisions of this Note as if such
transferee were the original Holder hereof, provided and to the extent such provisions are then applicable, and (ii) (A) there is then in effect a registration statement under the Securities Act, covering such proposed disposition and such
disposition is made in accordance with such registration statement, or (B) the Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed description of the manner and circumstances
of the proposed disposition, and, if requested by the Company, such Holder shall have furnished the Company, at its expense, with either (x) an opinion of counsel, reasonably satisfactory to the Company, to the effect that such disposition will
not require registration of such Securities under the Securities Act or (y) a “no action” letter from the Securities and Exchange Commission to the effect that the transfer of such securities without registration will not result in a
recommendation by the staff of the Securities and Exchange Commission that action be taken with respect thereto, whereupon the holder of such Securities shall be entitled to transfer such Securities in accordance with the terms of the notice
delivered by the Holder to the Company. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 under the Securities Act except in unusual circumstances. 

4.2 Permitted Transfers. Notwithstanding the provisions of Section 4.1 above, no such registration statement, prior consent
or opinion of counsel shall be necessary for (i) a transfer not involving a change in beneficial ownership, or (ii) in transactions involving the distribution without consideration by any Holder to (x) a parent, subsidiary or other
affiliate of the Holder that is a corporation, (y) any of its partners, members or other equity owners, or retired partners, retired members or other equity owners, or to the estate of any of its partners, members or other equity owners or
retired partners, retired members or other equity owners, or (z) a venture capital fund that is controlled by or under common control with one or more general partners or managing members of, or shares the same management company with, such
Holder, or (iii) transfers in compliance with 

  
 3 

 
Rule 144 under the Securities Act, as long as the Company is furnished with satisfactory evidence of compliance with such Rule; provided, in each case, that the Holder thereof shall give
written notice to the Company of such Holder’s intention to effect such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition. Each new certificate evidencing
this Note and/or the Securities so transferred shall bear the appropriate restrictive legends, except that such certificate shall not bear such restrictive legend if, in the opinion of counsel for the Company, such legend is not required in order to
establish or assist in compliance with any provisions of the Securities Act or any applicable state securities laws. 
 4.3
Titles and Subtitles. The titles and subtitles used in this Note are for convenience only and are not to be considered in construing or interpreting this Note. 
 4.4 Notices. All notices and other communications under this Note shall be in writing and shall be deemed given upon receipt if delivered personally, or when sent if mailed by registered or
certified mail (return receipt requested) or by reputable overnight express courier (charges prepaid) or transmitted by facsimile (with confirmation of transmittal) to the party to be notified at the address indicated for such party on the signature
page hereof, or at such other address as such party may designate by advance written notice to the other parties. 
 4.5
Attorneys’ Fees. If any action at law or in equity is necessary to enforce or interpret the terms of this Note, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and disbursements in addition to any other
relief to which such party may be entitled. 
 4.6 Amendments and Waivers. This Note may be amended and the observance of
any term of this Note may be waived (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company and the Required Holders. Any amendment or waiver effected in accordance with this
Section 4.6 shall be binding upon the Holder of this Note (and of any securities into which this Note is convertible), and each future holder of all such securities and the Company. 

4.7 Severability. If one or more provisions of this Note are held to be unenforceable under applicable law, such provision shall
be excluded from this Note and the balance of this Note shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.

 5Form of Director and Executive Officer Indemnification Agreement

 Exhibit 10.1 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement
(“Agreement”) is effective as of             , 20[    ] by and between Zogenix, Inc., a Delaware corporation (the
“Company”), and                             (“Indemnitee”).

 RECITALS 
 WHEREAS, highly competent persons have become more reluctant to serve corporations as directors, officers or in other capacities unless they are provided with adequate protection through insurance
and adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an
ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary and widespread practice among United
States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time,
directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought
only against the Company or business enterprise itself. The certificate of incorporation and bylaws of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to
the General Corporation Law of the State of Delaware (“DGCL”). The certificate of incorporation, bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive and thereby contemplate
that contracts may be entered into between the Company and members of the Board, officers and other persons with respect to indemnification; 
 WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons; 

WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the
best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance
expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the certificate of incorporation and bylaws of the Company and
any resolutions adopted pursuant thereto and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and 
 WHEREAS, Indemnitee does not regard the protection available under the Company’s certificate of incorporation, bylaws and insurance as adequate in the present circumstances and may not be
willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, to continue to serve and to take on additional service for or on behalf of the
Company on the condition that he or she be so indemnified. 

 NOW, THEREFORE, in consideration of the premises and the covenants contained herein,
the Company and Indemnitee do hereby covenant and agree as follows: 
 1. Services to the Company. Indemnitee will serve
or continue to serve as an officer, director or key employee of the Company for so long as Indemnitee is duly elected or appointed or until Indemnitee tenders his or her resignation. 

2. Definitions. As used in this Agreement: 
 (a) “Beneficial Owner” shall have the meaning given to such term in Rule 13d-3 under the Exchange Act; provided, however, that Beneficial Owner shall exclude any Person
otherwise becoming a Beneficial Owner by reason of the stockholders of the Company approving a merger of the Company with another entity. 
 (b) A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any of the following events: 

(i) Acquisition of Stock by Third Party. Any Person is or becomes the Beneficial Owner, directly or indirectly, of
securities of the Company representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities; 
 (ii) Change in Board of Directors. During any period of two (2) consecutive years (not including any period prior to the execution of this Agreement), individuals, who at the beginning of such
period constitute the Board, and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in Sections 2(b)(i), 2(b)(iii) or 2(b)(iv)) whose election by the
Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for
election was previously so approved, cease for any reason to constitute at least a majority of the members of the Board; 
 (iii) Corporate Transactions. The effective date of a merger or consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities
of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the
combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation and with the power to elect at least a majority of the board of directors or other governing body of such surviving
entity; 
 (iv) Liquidation. The approval by the stockholders of the Company of a complete liquidation of
the Company or an agreement or series of agreements for the sale or disposition by the Company of all or substantially all of the Company’s assets; or 
 (v) Other Events. There occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item
on any similar schedule or form) promulgated under the Exchange Act, whether or not the Company is then subject to such reporting requirement. 

  
 2 

 (c) “Corporate Status” describes the status of a person who is or was a
director, officer, trustee, general partner, managing member, fiduciary, employee or agent of the Company or of any other Enterprise which such person is or was serving at the request of the Company. 

(d) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in respect
of which indemnification is sought by Indemnitee. 
 (e) “Enterprise” shall mean the Company and any other
corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, trustee, general partner, managing
member, fiduciary, employee or agent. 
 (f) “Exchange Act” shall mean the Securities Exchange Act of 1934, as
amended. 
 (g) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs,
transcript costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the type customarily incurred in connection
with prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing to be a witness in, or otherwise participating in, a Proceeding. Expenses also shall include expenses incurred in connection with any appeal resulting
from any Proceeding, including, without limitation, the premium, security for and other costs relating to any cost bond, supersedeas bond or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by
Indemnitee or the amount of judgments or fines against Indemnitee. 
 (h) “Independent Counsel” means a law
firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party
(other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder.
Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the
Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any
and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 
 (i) “Person” shall have the meaning set forth in Sections 13(d) and 14(d) of the Exchange Act; provided, however, that Person shall exclude (i) the Company,
(ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company and (iii) any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their
ownership of stock of the Company. 
 (j) The term “Proceeding” shall include any threatened, pending or
completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, formal or informal, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in the right of the Company or
otherwise and whether of a civil, criminal, administrative or investigative nature, in which Indemnitee was, is or will be involved as a party, witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the
Company, by reason of any action taken (or failure to act) by him or her or of any action (or failure to act) on his or her part while acting as a director or officer of 

  
 3 

 
the Company, or by reason of the fact that he or she is or was serving at the request of the Company as a director, officer, trustee, general partner, managing member, fiduciary, employee or
agent of any other Enterprise, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement or advancement of Expenses can be provided under this Agreement.

 (k) References to “other enterprise” shall include employee benefit plans; references to
“fines” shall include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of
the Company which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he or she
reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this
Agreement. 
 3. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with the
provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant (as a witness or otherwise) in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor.
Pursuant to this Section 3, Indemnitee shall be indemnified against all Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect
of such Expenses, judgments, fines, penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in
good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful.

 4. Indemnity in Proceedings by or in the Right of the Company. The Company shall indemnify Indemnitee in accordance
with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant (as a witness or otherwise) in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to
this Section 4, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good
faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee
shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that any court in which the Proceeding was brought or the Delaware Court of Chancery shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 
 5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of this Agreement, to the extent that Indemnitee is a party to (or a participant
in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or her
in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection with each successfully resolved claim, issue or matter. If Indemnitee is not wholly successful in such Proceeding, the Company also
shall indemnify Indemnitee against all Expenses reasonably incurred in connection 

  
 4 

 
with a claim, issue or matter related to any claim, issue or matter on which Indemnitee was successful. For purposes of this Section and without limitation, the termination of any claim, issue or
matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 6. Indemnification For Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a witness in any Proceeding
to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection therewith. 

7. Additional Indemnification. 
 (a) Notwithstanding any limitation in Sections 3, 4 or 5, the Company shall indemnify Indemnitee to the fullest extent permitted by law if Indemnitee is a party to or threatened to be made a party to any
Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or
payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. No indemnity shall be made under this
Section 7(a) on account of Indemnitee’s conduct which constitutes a breach of Indemnitee’s duty of loyalty to the Company or its stockholders or is an act or omission not in good faith or which involves intentional misconduct or a
knowing violation of the law. 
 (b) For purposes of Section 7(a), the meaning of the phrase “to the fullest extent
permitted by law” shall include, but not be limited to: 
 (i) the fullest extent permitted by the
provision of the DGCL that authorizes or contemplates additional indemnification by agreement or the corresponding provision of any amendment to or replacement of the DGCL; and 

(ii) the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date
of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 
 8. Exclusions.
Notwithstanding any other provision in this Agreement, the Company shall not be obligated under this Agreement to indemnify Indemnitee in connection with any claim made against Indemnitee: 

(a) for which payment has actually been received by or on behalf of Indemnitee under any insurance policy or other indemnity provision,
except with respect to any excess beyond the amount actually received under any insurance policy or other indemnity provision; [FOR DIRECTORS AFFILIATED WITH A VC FUND ONLY: provided that the foregoing shall not affect the
rights of Indemnitee or the Fund Indemnitors set forth in Section 14(c) below;] 
 (b) for an accounting of profits made
from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common law; or 

(c) except as otherwise provided in Sections 13(d)-(f) hereof, prior to a Change in Control, in connection with any Proceeding (or
any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or 

  
 5 

 
its directors, officers, employees or other indemnitees, unless (i) the Board of Directors of the Company authorized the Proceeding (or any part of any Proceeding) prior to its initiation or
(ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 
 9. Advances of Expenses; Defense of Claim. 
 (a) Notwithstanding any
provision of this Agreement to the contrary, the Company shall advance the Expenses incurred by Indemnitee in connection with any Proceeding within ten (10) days after the receipt by the Company of a statement or statements requesting such
advances from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the expenses and without regard to
Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. Advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses
incurred preparing and forwarding statements to the Company to support the advances claimed. Indemnitee shall qualify for advances solely upon the execution and delivery to the Company of an undertaking providing that Indemnitee undertakes to repay
the advance to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. This Section 9(a) shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to
Section 8. 
 (b) The Company will be entitled to participate in the Proceeding at its own expense. 

(c) The Company shall not settle any action, claim or Proceeding (in whole or in part) which would impose any Expense, judgment, fine,
penalty or limitation on Indemnitee without Indemnitee’s prior written consent. 
 10. Procedure for Notification and
Application for Indemnification. 
 (a) Within sixty (60) days after the actual receipt by Indemnitee of notice that he
or she is a party to or a participant (as a witness or otherwise) in any Proceeding, Indemnitee shall submit to the Company a written notice identifying the Proceeding. The omission by Indemnitee to notify the Company will not relieve the Company
from any liability which it may have to Indemnitee (i) otherwise than under this Agreement and (ii) under this Agreement unless and only to the extent that the Company can establish that such omission to notify resulted in actual prejudice
to the Company. 
 (b) Indemnitee shall thereafter deliver to the Company a written application to indemnify Indemnitee in
accordance with this Agreement. Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate in his or her sole discretion. Following such a written application for indemnification by Indemnitee,
Indemnitee’s entitlement to indemnification shall be determined in accordance with Section 11(a) of this Agreement. 

11. Procedure Upon Application for Indemnification. 
 (a) Upon written request by Indemnitee for indemnification pursuant to Section 10(b), a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall be
made in the specific case: (i) by a majority vote of the Disinterested Directors, even if constituting less than a quorum of the Board; or (ii) if so requested by Indemnitee, in his or her sole discretion, by Independent Counsel in a
written opinion to the Board, a copy of which shall be delivered to Indemnitee. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee
shall reasonably cooperate with 

  
 6 

 
the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable
advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including
attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 
 (b) In the event the
determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 11(a) hereof, the Independent Counsel shall be selected as provided in this Section 11(b). If a Change in Control shall not have
occurred, the Independent Counsel shall be selected by the Board of Directors, and the Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected and the basis for the Board determination that
such counsel qualified as Independent Counsel. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board of Directors, in which event
the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within 10 days
after such written notice of selection shall have been received, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the
ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such
assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and
until such objection is withdrawn or a court of competent jurisdiction has determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 10(b)
hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition a court of competent jurisdiction (the “Court”) for resolution of any objection which shall have been made by
the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Court or by such other person as the Court shall designate, and the person with respect to
whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 11(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 13(a) of this Agreement,
Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

(c) The Company agrees to pay the reasonable fees of Independent Counsel and to fully indemnify such Independent Counsel against any and
all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 

12. Presumptions and Effect of Certain Proceedings. 
 (a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to
indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 10(b) of this Agreement, and the Company shall have the burden of proof to overcome that presumption in connection with
the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including 

  
 7 

 
by the Board or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because
Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by the Board or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (b) If the person, persons or entity
empowered or selected under Section 11 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the
requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact
necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day
period shall be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in good faith requires such additional time
for the obtaining or evaluating of documentation and/or information relating thereto. 
 (c) The termination of any Proceeding
or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely
affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or, with respect to
any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was unlawful. 
 (d) For
purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied
to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or
by an appraiser or other expert selected by the Enterprise. The provisions of this Section 12(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found to have met the
applicable standard of conduct set forth in this Agreement. 
 (e) The knowledge and/or actions, or failure to act, of any other
director, trustee, partner, managing member, fiduciary, officer, agent, advisor or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

13. Remedies of Indemnitee. 
 (a) In the event that (i) a determination is made pursuant to Section 11 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of
Expenses is not timely made pursuant to Section 9 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 11(a) of this Agreement within the time period specified in
Section 12(b) of this Agreement, (iv) payment of indemnification is not made pursuant to Section 5, 6, 7 or the last sentence of Section 11(a) of this Agreement within ten (10) days after receipt by the Company of a written
request therefor or (v) payment of indemnification pursuant to Section 3 or Section 4 of this Agreement is not made within ten (10) days after a determination has been made that

  
 8 

 
Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication by a court of his or her entitlement to such indemnification or advancement of Expenses. Alternatively,
Indemnitee, at his or her option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. The Company shall not oppose Indemnitee’s right to
seek any such adjudication or award in arbitration. 
 (b) In the event that a determination shall have been made pursuant to
Section 11(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 13 shall be conducted in all respects as a de novo trial or
arbitration on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 13, the Company shall have the burden of proving Indemnitee
is not entitled to indemnification or advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 11(a) of this Agreement adverse to Indemnitee for any purpose.
If Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 13, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 9 until a final determination is made with respect to
Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 
 (c) If a
determination shall have been made pursuant to Section 11(a) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this
Section 13, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification or
(ii) a prohibition of such indemnification under applicable law. 
 (d) In the event that Indemnitee, pursuant to this
Section 13, seeks a judicial adjudication of or an award in arbitration to enforce his or her rights under, or to recover damages for breach of, this Agreement, Indemnitee shall be entitled to recover from the Company, and shall be indemnified
by the Company against, any and all Expenses actually and reasonably incurred by him or her in such judicial adjudication or arbitration. If it shall be determined in said judicial adjudication or arbitration that Indemnitee is entitled to receive
part but not all of the indemnification or advancement of Expenses sought, Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all Expenses reasonably incurred by Indemnitee in
connection with such judicial adjudication or arbitration. 
 (e) The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 13 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company
is bound by all the provisions of this Agreement. 
 (f) The Company shall indemnify Indemnitee to the fullest extent permitted
by law against all Expenses and, if requested by Indemnitee, shall (within ten (10) days after the Company’s receipt of such written request) advance such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any
judicial proceeding or arbitration brought by Indemnitee for (i) indemnification or advances of Expenses by the Company under this Agreement or any other agreement or provision of the Company’s certificate of incorporation or bylaws now or
hereafter in effect or (ii) recovery or advances under any insurance policy maintained by any person for the benefit of Indemnitee, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advance or
insurance recovery, as the case may be.

 14. Non-exclusivity; Survival of Rights; Insurance; [FOR DIRECTORS AFFILIATED
WITH A VC FUND ONLY: Primacy of Indemnification;] Subrogation. 
 (a) The rights of indemnification and to receive
advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Company’s certificate of incorporation, the Company’s bylaws,
any agreement, a vote of stockholders, a resolution of directors or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any
action taken or omitted by such Indemnitee in his Corporate Status prior to such amendment, alteration or repeal. The parties hereto intend that, to the extent that a change in Delaware law, whether by statute or judicial decision, permits greater
indemnification or advancement of Expenses than would be afforded currently under the Company’s bylaws and this Agreement, the Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein
conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law, in equity or otherwise. The
assertion or employment of any right or remedy hereunder or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 
 (b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, trustees, partners, managing members, fiduciaries, employees or agents
of the Company or of any other Enterprise which such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any
such director, trustee, partner, managing member, fiduciary, officer, employee or agent under such policy or policies. If, at the time the Company receives notice from any source of a Proceeding as to which Indemnitee is a party or a participant (as
a witness or otherwise), the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company
shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 

(c) [FOR DIRECTORS AFFILIATED WITH A VC FUND ONLY: The Company hereby acknowledges that Indemnitee has certain rights to
indemnification, advancement of expenses and/or insurance provided by [INSERT NAME OF VC ENTITY] and certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the
indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary),
(ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and
as required by the terms of this Agreement and the certificate of incorporation or bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and,
(iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees
that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of
contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of
the terms of this Section 14(c).] 

  
 10 

 [(d)] [FOR DIRECTORS AFFILIATED WITH A VC FUND ONLY: Except as provided in
paragraph (c) above,] [i]n the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [FOR DIRECTORS AFFILIATED WITH A VC FUND ONLY:
(other than against the Fund Indemnitors)], who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

 [(e)] [FOR DIRECTORS AFFILIATED WITH A VC FUND ONLY: Except as provided in paragraph (c) above,] [t]he
Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received such payment
under any insurance policy, contract, agreement or otherwise. 
 [(f)] [FOR DIRECTORS AFFILIATED WITH A VC FUND
ONLY: Except as provided in paragraph (c) above,] [t]he Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, trustee, partner,
managing member, fiduciary, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such Enterprise. 

15. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten (10) years after
the date that Indemnitee shall have ceased to serve as a director or officer of the Company or as a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise which Indemnitee served at the request of the Company; or (b) one (1) year after the final termination of any Proceeding (including any rights of appeal thereto) then pending in respect of which
Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 13 of this Agreement relating thereto (including any rights of appeal of any Section 13
Proceeding). 
 16. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal
or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision
held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including,
without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent
manifested thereby. 
 17. Enforcement and Binding Effect. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in
order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the Company. 

  
 11 

 (b) This Agreement constitutes the entire agreement between the parties hereto with respect
to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 

(c) The indemnification and advancement of expenses provided by or granted pursuant to this Agreement shall apply to Indemnitee’s
service as an officer, director or key employee of the Company prior to the date of this Agreement. 
 (d) The indemnification
and advancement of expenses provided by or granted pursuant to this Agreement shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such
a person. 
 18. Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding
unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing waiver.

 19. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with any
summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the
Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise, except as provided in Section 10(a). 
 20. Notices. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given (a) if delivered by hand and if
receipt is acknowledged in writing by the party to whom said notice or other communication shall have been directed or (b) if mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is
so mailed: 
 (a) If to Indemnitee, at the address indicated on the signature page of this Agreement, or such other address as
Indemnitee shall provide in writing to the Company. 
 (b) If to the Company to: 

Zogenix, Inc. 

12671 High Bluff Drive, Suite 200 
 San Diego, California 92130 
 Attn.: Secretary 

or to any other address as may have been furnished to Indemnitee in writing by the Company. 

21. Contribution. To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is
unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in
settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect:
(i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving rise to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and
agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

  
 12 

 22. Applicable Law and Consent to Jurisdiction. This Agreement and the legal
relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant
to Section 13(a) of this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Chancery Court
of the State of Delaware (the “Delaware Court”) and not in any other state or federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Delaware
Court for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) appoint, to the extent such party is not a resident of the State of Delaware, irrevocably Corporation Service Company, 2711 Centerville
Road, Suite 400, in the City of Wilmington, County of New Castle, as its agent in the State of Delaware as such party’s agent for acceptance of legal process in connection with any such action or proceeding against such party with the same
legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court and (v) waive and agree not to plead or
to make any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum. 
 23. Identical Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute
one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement. 

24. Miscellaneous. Use of the masculine pronoun shall be deemed to include usage of the feminine pronoun where appropriate. The
headings of the sections and paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof.
