Termination Period:


 


This Option shall
be exercisable for [thirty (30) days] after Participant ceases to be a Service Provider, unless such termination is due to Participant’s

		II.	AGREEMENT



 


1.          Grant
of Option. The Administrator of the Company hereby grants to the Participant named in the Notice of Stock Option Grant in Part
I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of Shares set forth
in the Notice of Stock Option Grant, at the exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise
Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 16
of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions
of the Plan shall prevail.


 


If designated in the
Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive
Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code
Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if for any reason
this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion
thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the Company or any Parent or Subsidiary
or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of
the Option to qualify for any reason as an ISO.


 


		2.	Exercise of Option.



 


(a)          Right
to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice
of Stock Option Grant and with the applicable provisions of the Plan and this Option Agreement.


 


(b)          Method
of Exercise. This Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A
(the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall
state the election to exercise the Option, the number of Shares with respect to which the Option is being exercised (the “Exercised
Shares”), and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied
by payment of the aggregate Exercise Price as to all Exercised Shares, together with any applicable tax withholding. This Option
shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate
Exercise Price, together with any applicable tax withholding.


 




    -2-


     


    

 


No Shares shall be issued
pursuant to the exercise of an Option unless such issuance and such exercise comply with Applicable Laws. Assuming such compliance,
for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised
with respect to such Shares.


 


3.           Participant’s
Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities
Act”), at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise
of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B.


 


4.           Lock-Up
Period. Participant hereby agrees that Participant shall not offer, pledge, sell, contract to sell, sell any option or contract
to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer
or dispose of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or
other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock
(or other securities) of the Company held by Participant (other than those included in the registration) for a period specified
by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty
(180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other
period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication
or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the
restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto).


 


Participant agrees to
execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are consistent
with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative
of the underwriters of Common Stock (or other securities) of the Company, Participant shall provide, within ten (10) days of such
request, such information as may be required by the Company or such representative in connection with the completion of any public
offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations
described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction
on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect
to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred and
eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option
shall be bound by this Section 4.


 


5.            Method
of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a combination thereof, at the election
of the Participant:


 


(a)          cash;


 




    -3-


     


    

 


(b)          check;


 


(c)          consideration
received by the Company under a formal cashless exercise program adopted by the Company in connection with the Plan; or


 


(d)          surrender
of other Shares which (i) shall be valued at its Fair Market Value on the date of exercise, and (ii) must be owned free and clear
of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of the Administrator,
shall not result in any adverse accounting consequences to the Company.


 


6.            Restrictions
on Exercise. This Option may not be exercised until such time as the Plan has been approved by the stockholders of the Company,
or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute
a violation of any Applicable Law.


 


7.            Non-Transferability
of Option.


 


(a)          This
Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of Participant.


 


(b)          Further,
until the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, or after the Administrator
determines that it is, will, or may no longer be relying upon the exemption from registration of Options under the Exchange Act
as set forth in Rule 12h-1(f) promulgated under the Exchange Act (the “Reliance End Date”), Participant shall not transfer
this Option or, prior to exercise, the Shares subject to this Option, in any manner other than (i) to persons who are “family
members” (as defined in Rule 701(c)(3) of the Securities Act) through gifts or domestic relations orders, or (ii) to an executor
or guardian of Participant upon the death or disability of Participant. Until the Reliance End Date, the Options and, prior to
exercise, the Shares subject to this Option, may not be pledged, hypothecated or otherwise transferred or disposed of, including
by entering into any short position, any “put equivalent position” or any “call equivalent position” (as
defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, respectively), other than as permitted in clauses (i) and (ii)
of this paragraph.


 


8.           Term
of Option. This Option may be exercised only within the term set out in the Notice of Stock Option Grant, and may be exercised
during such term only in accordance with the Plan and the terms of this Option Agreement.


 




    -4-


     


    

 


		9.	Tax Obligations.



 


(a)          Tax
Withholding. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or
retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements
applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse
to deliver the Shares if such withholding amounts are not delivered at the time of exercise.


 


(b)          Notice
of Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein is an ISO, and if Participant sells
or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years
after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant shall immediately notify the
Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company
on the compensation income recognized by Participant.


 


(c)          Code
Section 409A. Under Code Section 409A, an Option that vests after December 31, 2004 (or that vested on or prior to such date
but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by
the Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “discount
option”) may be considered “deferred compensation.” An Option that is a “discount option” may result
in (i) income recognition by Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income
tax, and (iii) potential penalty and interest charges. The “discount option” may also result in additional state income,
penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS
will agree that the per Share exercise price of this Option equals or exceeds the Fair Market Value of a Share on the date of grant
in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price
that was less than the Fair Market Value of a Share on the date of grant, Participant shall be solely responsible for Participant’s
costs related to such a determination.


 


10.         Entire
Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements
of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s
interest except by means of a writing signed by the Company and Participant. This Option Agreement is governed by the internal
substantive laws but not the choice of law rules of Arizona.


 


11.         No
Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE
HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR
RETAINING PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT
FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH
HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR
ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT
OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME,
WITH OR WITHOUT CAUSE.

Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator
upon any questions arising under the Plan or this Option. Participant further agrees to notify the Company upon any change in the

2010 EQUITY INCENTIVE PLAN


 


EXERCISE NOTICE


 


Cancer Prevention Pharmaceuticals, Inc.


 


Attention:


 


Exercise of Option.
Effective as of today, ________________, ____, the undersigned (“Participant”) hereby elects to exercise Participant’s
option (the “Option”) to purchase ________________ shares of the Common Stock (the “Shares”) of Cancer
Prevention Pharmaceuticals, Inc. (the “Company”) under and pursuant to the 2010 Equity Incentive Plan (the “Plan”)
and the Stock Option Agreement dated ______________, _____ (the “Option Agreement”).


 


Delivery of Payment.
Participant herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option Agreement, and any
and all withholding taxes due in connection with the exercise of the Option.


 


Representations
of Participant. Participant acknowledges that Participant has received, read and understood the Plan and the Option Agreement
and agrees to abide by and be bound by their terms and conditions.


 


Rights as Stockholder.
Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the
Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall be issued to Participant as soon
as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend
or other right for which the record date is prior to the date of issuance except as provided in Section [13]
of the Plan.


 


Company’s
Right of First Refusal. Before any Shares held by Participant or any transferee (either being sometimes referred to herein
as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company
or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in this Section 5
(the “Right of First Refusal”).


 


Notice of Proposed
Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the
Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or
other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee;
and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered
Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s).


 




     


     


    

 


Exercise of Right
of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred
to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (c) below.


 


Purchase Price.
The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5
shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash
consideration shall be determined by the Board of Directors of the Company in good faith.


 


Payment. Payment
of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all
or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the
assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times
set forth in the Notice.


 


Holder’s Right
to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section 5, then the Holder may sell or otherwise transfer such Shares
to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated
within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance
with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5
shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred
to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred.


 


Exception for Certain
Family Transfers. Anything to the contrary contained in this Section 5 notwithstanding, the transfer of any or all of
the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s
immediate family or a trust for the benefit of the Participant’s immediate family shall be exempt from the provisions of
this Section 5. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father,
mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject
to the provisions of this Section 5, and there shall be no further transfer of such Shares except in accordance with the terms
of this Section 5.


 


Termination of Right
of First Refusal. The Right of First Refusal shall terminate as to any Shares upon the earlier of (i) the first sale of Common
Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities
that are publicly traded.


 


Tax Consultation.
Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s purchase or disposition
of the Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection
with the purchase or disposition of the Shares and that Participant is not relying on the Company for any tax advice.

understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to
be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the

OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY

it may make appropriate notations to the same effect in its own records.


 


Refusal to Transfer.
The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Exercise Notice or (ii) to treat as owner of such Shares or to accord the right

to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator
shall be final and binding on all parties.


 


Governing Law; Severability.

any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise
Notice shall continue in full force and effect.


 


Entire Agreement.
The Plan and Option Agreement are incorporated herein by reference. This Exercise Notice, the Plan, the Option Agreement and the
Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and

INVESTMENT REPRESENTATION STATEMENT


 


	PARTICIPANT	:	 
	 	 	 
	COMPANY	:	CANCER PREVENTION PHARMACEUTICALS, INC.
	 	 	 
	SECURITY	:	COMMON STOCK
	 	 	 
	AMOUNT	:	 
	 	 	 
	DATE	:	 


 


In connection with
the purchase of the above-listed Securities, the undersigned Participant represents to the Company the following:


 


(a)          Participant
is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment
for Participant’s own account only and not with a view to, or for resale in connection with, any “distribution”
thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).


 


(b)          Participant
acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have
not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among
other things, the bona fide nature of Participant’s investment intent as expressed herein. In this connection, Participant
understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable
if Participant’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital
gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the
Securities, or for a period of one (1) year or any other fixed period in the future. Participant further understands that the Securities
must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration
is available. Participant further acknowledges and understands that the Company is under no obligation to register the Securities.
Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable
state securities laws.


 




     


     


    

 


(c)          Participant
is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance,
permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in
a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under
Rule 701 at the time of the grant of the Option to Participant, the exercise shall be exempt from registration under the Securities
Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144,
including in the case of affiliates (1) the availability of certain public information about the Company, (2) the amount
of Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made
in an unsolicited “broker’s transaction”, transactions directly with a “market maker” or “riskless
principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing
of a Form 144, if applicable.


 


In the event that the
Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public information
about the Company; (ii) the resale to occur more than a specified period after the purchase and full payment (within the meaning
of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction of
the conditions set forth in sections (2), (3) and (4) of the paragraph immediately above.


 


(d)          Participant
further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration
under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding
the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion
that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 shall have a substantial burden of proof in establishing that an exemption from registration is available
for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their
own risk. Participant understands that no assurances can be given that any such other registration exemption shall be available
in such event.
