September 7, 2015 
 Mr. Konstantinos Alataris 

Dear Konstantinos: 
 This letter will confirm
the terms and conditions of your employment with ZP Opco, Inc., a Delaware corporation (the “Company”) and wholly owned subsidiary of Zosano Pharma Corporation, a Delaware corporation (the “Parent”).

 1. Position and Duties. Effective September 21, 2015 (the “Start Date”), you will be elected as the
President of the Parent and the President and Chief Operating Officer of the Company. You will report to the Chief Executive Officer of the Parent (the “CEO”). Like other officers of the Parent, you will be a full-time
employee of the Company. You agree to perform the duties of your positions and such other duties as may reasonably be assigned to you from time to time by the CEO. You also agree that, while employed by the Company, you will devote your full
business time and your best efforts, business judgment, skill and knowledge to the advancement of the business and interests of the Parent, the Company and their respective Affiliates (as defined in Section 6) and to the discharge of your
duties and responsibilities for them. 
 2. Compensation and Benefits. During your employment, as compensation for the services
performed by you for the Company and its Affiliates, the Company will provide you the following pay and benefits: 
 (a) Base Salary.
The Company will pay you a base salary at the rate of $375,000 per year, payable in accordance with the regular payroll practices of the Company and subject to increase from time to time by the Compensation Committee of the Board (the
“Compensation Committee”) in its discretion. 
 (b) Bonus Compensation. During employment, you will be
considered annually for a bonus target of 30% of your base salary. The amount of any bonus awarded, whether in cash or stock, will be determined by the Compensation Committee in its discretion, after consideration of a proposal from the CEO, and
will be based on (i) your performance and the performance of the Company against goals established annually and (ii) the terms and conditions of the Parent’s employee bonus program, adopted by the Compensation Committee on
February 27, 2015. 
 (c) Stock Options. The Compensation Committee shall grant you, under Parent’s Amended and Restated
2014 Equity and Incentive Plan, an incentive stock option to purchase 209,394 shares of common stock, $0.0001 par value per share, of Parent (“Common Stock”). Such stock option shall (A) have an exercise price per share equal
to the closing price per share of Common Stock on the date of the grant, and (B) be subject to vesting requirements such that 25% of the total option shares shall vest on first anniversary of the date of grant and

an additional 2.0833% of the total option shares shall vest thereafter on the monthly anniversary of such date; provided, however, that 18.75% of the total option shares (in addition to
any then-vested option shares) shall vest upon termination of employment pursuant to the last sentence of Section 4(a) or the first sentence of Section 4(b); provided, further, that 100% of any then unvested option shares shall vest
upon a Constructive Termination Event (as defined in Section 5(b)). 
 (d) Participation in Employee Benefit Plans. You shall be
entitled to participate in any and all employee benefit plans from time to time in effect for the full-time employees of the Company generally, but the Company shall not be required to establish any such program or plan. Such participation shall be
subject to (i) the terms of the applicable plan documents and (ii) generally applicable Company policies. The Company may alter, modify, add to or delete its employee benefit plans at any time as it, in its sole discretion, determines to
be appropriate. 
 (e) Vacations. You will be entitled to three weeks of paid vacation per year, in addition to holidays observed by
the Company. Vacation may be taken at such times and intervals as you shall determine, subject to the reasonable business needs of the Company. 

(f) Business Expenses. The Company will pay or reimburse you for all reasonable business expenses incurred or paid by you in the
performance of your duties and responsibilities for the Company, subject to any maximum annual limit and other restrictions on such expenses set by the Company and to such reasonable substantiation and documentation as it may specify from time to
time. 
 3. Confidential Information and Restricted Activities. 

(a) Confidential Information. During the course of your employment with the Company, you will learn of Confidential Information (as
defined in Section 6), and you may develop Confidential Information on behalf of the Company. You agree that you will not use or disclose to any Person (as defined in Section 6) any Confidential Information obtained by you incident to your
employment or any other association with the Company or any of its Affiliates, except as required by applicable law or for the proper performance of your regular duties and responsibilities for the Company. You understand that this restriction shall
continue to apply for three (3) years after your employment terminates, regardless of the reason for such termination. In addition, you agree to sign the Company’s standard form of invention assignment agreement as a condition of your
employment hereunder. 
 (b) Protection of Documents. All documents, records and files, in any media of whatever kind and
description, relating to the business, present or otherwise, of the Parent, the Company or any of their respective Affiliates, and any copies, in whole or in part, thereof (the “Documents”), whether or not prepared by you, shall be
the sole and exclusive property of the Company. You agree to safeguard all Documents and to surrender to the Company, at the time your employment terminates or at such earlier time or times as the CEO may specify, all Documents then in your
possession or control.

 (c)
Non-Solicitation. You acknowledge that in your employment with the Company you will have access to Confidential Information which, if disclosed, would assist in competition against the Company and its Affiliates, and that you will also
generate good will for the Company and its Affiliates in the course of your employment. Therefore, you agree that the following restrictions on your activities during and after the termination of your employment are necessary to protect the good
will, Confidential Information and other legitimate interests of the Company and its Affiliates: While you are employed by the Company and during the 12 months immediately following termination of your employment for whatever reason, you shall not,
directly or through any other Person, (A) seek to persuade any employee of the Company or any of its Affiliates to discontinue employment or (B) solicit or encourage any customer, distributor, vendor, or other business partner of the
Company or any of its Affiliates or any independent contractor providing services to the Company or any of its Affiliates to terminate or diminish its relationship with them. For purposes of the foregoing, the terms “employee,”
“customer,” “distributor,” and “vendor” shall also include any person or party who held such status during the immediately preceding six (6) months. 

(d) Enforcement of Restrictions. In signing this letter agreement, you give the Company assurance that you have carefully read and
considered all the terms and conditions of this letter agreement, including the restraints imposed on you under this Section 3. You agree without reservation that these restraints are necessary for the reasonable and proper protection of the Company
and its Affiliates, and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area. You further agree that, were you to breach any of the covenants contained in this Section 3, the
damage to the Company and its Affiliates would be irreparable. You therefore agree that the Company, in addition to any other remedies available to it, shall be entitled to preliminary and permanent injunctive relief against any breach or threatened
breach by you of any of those covenants, without having to post bond. You also agree that the period of restriction in Section 3(c) shall be tolled and shall not run during any period you are in violation thereof. You and the Company further agree
that, in the event that any provision of this Section 3 is determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of
activities, that provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law. It is also agreed that each of the Company’s Affiliates shall have the right to enforce all of your obligations to that
Affiliate under this letter agreement, including without limitation pursuant to this Section 3. It is agreed and understood that the terms of this letter agreement are severable, and that no breach of any provision of this letter agreement or
any other purported violation of law by the Company shall operate to excuse you from the performance of your obligations under this Section 3. 

4. Termination of Employment. Your employment under this letter agreement shall continue for no definite term until terminated pursuant
to this Section 4. 
 (a) The Company may terminate your employment for Cause upon notice to you setting forth in reasonable detail the
nature of the Cause (as defined below). The

following, as determined by the Company in its reasonable judgment, shall constitute “Cause” for termination: (i) your persistent and willful refusal to follow reasonable
directives of the CEO; (ii) gross negligence or willful misconduct in the performance of your duties and responsibilities to the Company or any of its Affiliates; (iii) your material breach of this letter agreement or any other agreement
between you and the Company or any of its Affiliates, which breach continues for more than 15 days after the Company gives you written notice which sets forth in reasonable detail the nature of such breach; or (iv) other conduct by you that is
or could reasonably anticipated to be materially harmful to the business, interests or reputation of the Company or any of its Affiliates. The Company also may terminate your employment other than for Cause upon written notice to you. 

(b) You may terminate your employment for Good Reason (as defined below) upon notice to the Company setting forth in reasonable detail the
nature of the Good Reason. The following shall constitute “Good Reason” for termination: (i) the Company’s failure to continue you in the position of President and Chief Operating Officer of the Company with such duties
typically associated with such position, or (ii) material failure of the Company to provide you compensation and benefits in accordance with the terms of Section 2, above, for more than ten (10) business days after notice from you
specifying in reasonable detail the nature of such failure, except in connection with a decrease in salary affecting each senior management employee of the Company in a proportionate manner, or (iii) relocation of your principal place of
employment to a location other than the greater San Francisco Bay area, California. You may also terminate your employment other than for Good Reason upon 30 days’ written notice to the Company. 

(c) In the event you become disabled during employment and, as a result, are unable to continue to perform substantially all of your duties
and responsibilities under this letter agreement, either with or without reasonable accommodation, the Company will continue to pay you your base salary and to provide you benefits in accordance with Section 2(d) above, to the extent permitted
by plan terms, for up to twelve (12) weeks of disability during any period of three hundred and sixty-five (365) consecutive calendar days. If you are unable to return to work after twelve (12) weeks of disability, the Company may
terminate your employment, upon notice to you. If any question shall arise as to whether you are disabled to the extent that you are unable to perform substantially all of your duties and responsibilities for the Company and its Affiliates, you
shall, at the Company’s request, submit to a medical examination by a physician selected by the Company to whom you or your guardian, if any, has no reasonable objection to determine whether you are so disabled, and such determination shall for
the purposes of this letter agreement be conclusive of the issue. If such a question arises and you fail to submit to the requested medical examination, the Company’s determination of the issue shall be binding on you. 

5. Severance Payments and Other Matters Related to Termination. 

(a) Involuntary Termination. In the event of termination of your employment by the Company other than for Cause, or in the event of
your termination of employment for Good Reason, the Company will (i) continue to pay you your base salary for a

period of nine (9) months from and after the date of termination, (ii) pay you an amount equal to the lesser of (x) the target bonus of 30% of your base salary pro rata for such
nine (9) months or (y) the amount of the annual bonus awarded to you in respect of the prior year pro rata for nine (9) months, such bonus severance to be paid in equal installments during the nine (9)- month period following the date
of termination, and (iii) continue to provide you with group health and dental plan benefits for a period of nine (9) months from and after the date of termination, with the cost of the regular premiums for such benefits shared in the same
relative proportion by the Company and you as in effect on the date of termination. The Company will also pay you on the date of termination any base salary earned but not paid through the date of termination, and pay for any vacation time accrued
but not used to that date. In addition, as provided in Section 2(c), the vesting schedule for any stock options outstanding on the date of termination will automatically accelerate so that 18.75% of the total option shares shall immediately
vest and become exercisable upon such termination. Except as set forth in clause (ii) and (iii) of the first sentence of this Section 5(a), benefits shall terminate in accordance with the terms of the applicable benefit plans based on
the date of termination of your employment. 
 (b) Involuntary Termination within One Year after Change in Control. In the event of
termination of your employment by the Company (or its successor) other than for Cause, or in the event of your termination of employment for Good Reason, in either case during the one (1)-year period following a Change in Control (a
“Constructive Termination Event”), the Company (or its successor) will, in lieu of any severance under Section 5(a) above, (i) continue to pay you your base salary for a period of nine (9) months from and after the
date of termination, (ii) pay you an amount equal to the lesser of (x) the target bonus of 30% of your base salary pro rata for such nine (9) months or (y) the amount of the annual bonus awarded to you in respect of the prior
year pro rata for nine (9) months, such bonus severance to be paid in equal installments during the nine (9)-month period following the date of termination, and (iii) continue to provide you with group health and dental plan benefits for a
period of nine (9) months from and after the date of termination, with the cost of all regular premiums for such benefits paid by the Company. The Company will also pay you on the date of termination any base salary earned but not paid through
the date of termination, and pay for any vacation time accrued but not used to that date. In addition, as provided in Section 2(c), the vesting schedule for any stock options outstanding on the date of termination will automatically accelerate
so that 100% of any then unvested option shares shall immediately vest and become exercisable upon such termination. Except as set forth in clause (ii) and (iii) of the first sentence of this Section 5(b), benefits shall terminate in
accordance with the terms of the applicable benefit plans based on the date of termination of your employment. 
 (c) Severance
Conditional Upon Release. Any obligation of the Company to provide you severance payments under Sections 5(a) and 5(b) above shall be conditioned upon your signing a general release of claims in the form provided by the Company and reasonably
acceptable to you (the “Employee Release”) within twenty-one (21) days after the date on which you give or receive, as applicable, notice of termination of your employment and upon your not revoking the Employee Release
thereafter. All base salary and bonus severance payments will be payable in accordance with the normal payroll practices of the Company, and 








 Mr. Konstantinos Alataris 

September 7, 2015

will begin at the Company’s next regular payroll period following the effective date of the Employee Release, but shall be retroactive to the date of termination. For the avoidance of doubt,
no cash compensation that may be earned by you pursuant to employment or a consulting arrangement with a Person other than the Company during the period of time that the Company (or its successor) is making payments to you pursuant to this
Section 5 shall be credited toward the Company’s severance obligations under this Section 5. Notwithstanding anything to the contrary contained in this letter agreement, in the event that at the time of your separation from service
you are a “specified employee,” as hereinafter defined, any and all amounts payable under this Section 5 in connection with such separation from service that constitute deferred compensation subject to Section 409A of the
Internal Revenue Code of 
 1986, as amended (“Section 409A”), as determined by the Company in its sole discretion, and that would (but for
this sentence) be payable within six (6) months following such separation from service, shall instead be paid on the date that follows the date of such separation from service by six (6) months. For purposes of the preceding sentence,
“separation from service” shall be determined in a manner consistent with subsection (a)(2)(A)(i) of Section 409A and the term “specified employee” shall mean an individual determined by the Company to be a
specified employee as defined in subsection (a)(2)(B)(i) of Section 409A. 
 (d) Termination for Cause or Voluntary Termination.
In the event of termination of your employment by the Company for Cause or your termination other than for Good Reason, the Company will pay you any base salary earned but not paid through the date of termination and pay for any vacation time
accrued but not used to that date. The Company shall have no obligation to pay you any bonus compensation or severance payments. Except for any right you may have under the federal law known as “COBRA” to continue participation in the
Company’s group health and dental plans at your cost, benefits shall terminate in accordance with the terms of the applicable benefit plans based on the date of termination of your employment. 

(e) Survival of Certain Provisions. Provisions of this letter agreement shall survive any termination if so provided in this letter
agreement or if necessary or desirable to accomplish the purposes of other surviving provisions, including without limitation your obligations under Section 3 of this letter agreement. The obligation of the Company to make severance payments to
you under Section 5(a) or 5(b) above, and your right to retain such payments, are expressly conditioned upon your continued full performance of your obligations under Section 3 hereof. Upon termination by either you or the Company, all
rights, duties and obligations of you and the Company to each other shall cease, except as otherwise expressly provided in this letter agreement. 

6. Definitions. For purposes of this letter agreement, the following definitions apply: 

“Affiliates” means all persons and entities directly or indirectly controlling, controlled by or under common control with

11. Miscellaneous. This letter agreement sets forth the entire agreement between you and the Company and replaces all prior and
contemporaneous communications, agreements and understandings, written or oral, with respect to the terms and conditions of your employment with the Company. This letter agreement may not be modified or amended, and no breach shall be deemed to be
