 Attachments: Additional Terms and Conditions; Notice of Exercise of Stock Option and Investment Representations;
Crinetics Pharmaceuticals, Inc. amended and restated 2015 Stock Incentive Plan. 
  

	1 	If Optionee is a 10% Stockholder (as defined in the Plan) as of the Grant Date, and the Option is an Incentive Option, the Option will expire five (5) years from the Grant Date, unless terminated earlier as
provided in the Option Agreement. 








 ADDITIONAL TERMS AND CONDITIONS 

The terms and conditions set forth below constitute part of the Stock Option Agreement to which they are attached, and references herein to
the “Option Agreement” include both documents as one agreement. 
 1.    Grant of Option.
The Company has granted to the Optionee an Option to purchase all or any portion of the number of Shares at the exercise price per share (the “Exercise Price”) stated on the first page of this Option Agreement. If the box marked
“Incentive Option” on the first page hereof is checked, then this Option is intended to qualify as an “incentive stock option” as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
“Code”). If this Option fails in whole or in part to qualify as an incentive stock option, or if the box marked “Nonqualified Option” on the first page hereof is checked, then this Option shall to that extent constitute a
nonqualified stock option. 
 2.    Vesting of Option. The right to exercise this Option shall vest
and become exercisable as set forth on the first page of this Option Agreement. No additional Shares shall vest after the date of termination of Optionee’s “Continuous Service” (as defined below), but this Option shall continue to be
exercisable in accordance with Section 3 hereof with respect to that number of Shares that have vested as of the date of termination of Optionee’s Continuous Service. 

For purposes of this Option Agreement, the term “Continuous Service” means (a) employment by either the Company or any
parent or subsidiary corporation of the Company, or by a corporation or a parent or subsidiary of a corporation issuing or assuming a stock option in a transaction to which Section 424(a) of the Code applies, which is uninterrupted except for
vacations, illness (not including Disability), or leaves of absence which are approved in writing by the Company or any of such other employer corporations, if applicable, (b) service as a member of the Board until Optionee resigns, is removed
from office, or Optionee’s term of office expires and he or she is not reelected, or (c) so long as Optionee is engaged as a Consultant or other Service Provider. 

3.    Term of Option. The right of the Optionee to exercise this Option shall terminate upon the
first to occur of the following: 
 (a)    the expiration of ten (10) years from the Grant Date;2 
 (b)    the expiration of one (1) year from the date of
termination of Optionee’s Continuous Service if such termination is due to Disability of the Optionee; 

(c)    the expiration of one (1) year from the date of termination of Optionee’s Continuous Service if
such termination is due to Optionee’s death or if death occurs during either the three-month or thirty (30) day period following termination of Optionee’s Continuous Service pursuant to Section 3(d) or 3(e), as the case may be;

 (d)    the expiration of three (3) months from the date of termination of Optionee’s Continuous
Service if such termination occurs for any reason other than Disability, death, voluntary resignation or Cause; provided, however, that if Optionee dies during such three-month period the provisions of Section 3(c) shall apply; 

 

	2 	If Optionee is a 10% Stockholder (as defined in the Plan) as of the Grant Date, and to the extent that the Option is an Incentive Option, the Option will expire five (5) years from the Grant Date.









 (e)    the expiration of thirty (30) days from the date of
termination of Optionee’s Continuous Service if such termination occurs due to voluntary resignation; provided, however, that if Optionee dies during such thirty (30) day period the provisions of Section 3(c) shall apply; or 

(f)    the termination of Optionee’s Continuous Service, if such termination is for Cause. 

4.    Exercise of Option. 

(a)    General. On or after the vesting of any portion of this Option in accordance with Sections 2 or 10
hereof, and until termination of the right to exercise this Option in accordance with Section 3, the portion of this Option that has vested may be exercised in whole or in part by the Optionee (or, after his or her death, by the person
designated pursuant to Section 5) upon delivery of the following to the Company at its principal executive offices: 

(i)    Notice of Exercise of Stock Option and Investment Representations, in the form attached as Exhibit
A to this Option Agreement, which identifies this Option Agreement, states the number of Shares then being purchased, and sets forth the investment intent of the Optionee or person designated pursuant to Section 5, as the case may be;

 (ii)    payment of the total Exercise Price for the Shares being purchased in accordance with
Section 4(b); and 
 (iii)    payment of any applicable withholding taxes in accordance with
Section 4(c) below. 
 (b)    Payment of Exercise Price. The Optionee may elect to pay the Exercise
Price by any of the following methods of payment: 
 (i)    cash or check; 

(ii)    Subject to the approval of the Administrator at the time of exercise and restrictions under applicable
law, a “net exercise” arrangement pursuant to which the Company will reduce the number of Shares to be issued upon exercise by the number of Shares having an aggregate Fair Market Value as of the date of exercise equal to the total
Exercise Price. The Shares used to pay the Exercise Price under this “net exercise” provision shall be considered to have resulted from the exercise of this Option, and accordingly, this Option will not again be exercisable with respect to
such Shares, as well as any Shares actually delivered to Optionee; 
 (iii)    Subject to the approval of the
Administrator at the time of exercise and restrictions under applicable law, delivery of Shares already owned by Optionee having an aggregate Fair Market Value as of the date of exercise equal to the total Exercise Price. “Delivery” for
these purposes, in the sole discretion of the Administrator at the time of exercise, shall include delivery to the Company of the certificate(s) representing the Shares or Optionee’s attestation of ownership of such Shares in a form approved by
the Administrator; 
 (iv)    such other form of consideration as may be approved by the Administrator from time
to time to the extent permitted by applicable law; or 
 (v)    any combination of the foregoing. 







 (c)    Withholding. At the time of exercise of this Option,
Optionee shall deliver to the Company a check or cash in the amount reasonably requested by the Company to satisfy the Company’s withholding obligations under federal, state or other applicable tax laws with respect to the taxable income, if
any, recognized by the Optionee in connection with the exercise of this Option. The Company shall have the authority and the right to deduct or withhold, or require Participant to remit to the Company, an amount sufficient to satisfy federal, state,
local and foreign taxes (including Participant’s employment tax obligation) required by law to be withheld with respect to any taxable event concerning Participant arising as a result of this Option or otherwise under this Agreement, including,
without limitation, the authority to deduct such amounts from other compensation payable to Participant by the Company or, with the consent of the Administrator, the authority to reduce the number of Shares to be issued upon exercise of this (so
long as such withholding will not result in adverse accounting consequences to the Company), provided such arrangements satisfy the requirements of applicable law (with any such withholding based on the minimum statutory withholding rates (or such
other rate as may be determined by the Company after considering any accounting consequences or costs). 

5.    Death of Optionee; No Assignment. The rights of the Optionee under this Option Agreement may
not be assigned or transferred except by will or the laws of descent and distribution and may be exercised during the lifetime of the Optionee only by such Optionee. Any attempt to sell, pledge, assign, hypothecate, transfer or dispose of this
Option in contravention of this Option Agreement or the Plan shall be void and shall have no effect. If the Optionee’s Continuous Service terminates as a result of his or her death, and provided Optionee’s rights hereunder shall have
vested pursuant to Section 2 hereof, Optionee’s legal representative, his or her legatee, or the person who acquired the right to exercise this Option by reason of the death of the Optionee (individually, a “Successor”)
shall succeed to the Optionee’s rights and obligations under this Option Agreement. After the death of the Optionee, only a Successor may exercise this Option. 

6.    Representations and Warranties of Optionee. 

(a)    Own Account for Investment. Optionee represents and warrants that this Option is being
acquired by Optionee for Optionee’s personal account, for investment purposes only, and not with a view to the distribution, resale or other disposition thereof. At no time was Optionee presented with or solicited by any publicly issued or
circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Shares. 

(b)    Shares Unregistered. Optionee acknowledges that the Company may issue Shares upon the exercise
of the Option without registering such Shares under the Securities Act of 1933, as amended (the “Securities Act”), on the basis of certain exemptions from such registration requirement. Accordingly, Optionee agrees that his or her
exercise of the Option may be expressly conditioned upon his or her delivery to the Company of an investment certificate including such representations and undertakings as the Company may reasonably require in order to assure the availability of
such exemptions, including a representation that Optionee is acquiring the Shares for investment and not with a present intention of selling or otherwise disposing thereof and an agreement by Optionee that the certificates evidencing the Shares may
bear a legend indicating such non-registration under the Securities Act and the resulting restrictions on transfer. Optionee acknowledges that, because Shares received upon exercise of an Option may be
unregistered, Optionee may be required to hold the Shares indefinitely unless they are subsequently registered for resale under the Securities Act or an exemption from such registration is available. 

(c)    Agrees to Terms of the Plan. Optionee has received a copy of the Plan and has read and
understands the terms of the Plan and this Option Agreement, and agrees to be bound by their 







 
terms and conditions. Optionee understands that all rights and obligations connected with this Option are set forth in this Option Agreement and in the Plan. 

(d)    SEC Rule 144. Optionee has been advised that Rule 144 promulgated under the Securities Act,
which permits certain limited sales of unregistered securities, is not presently available with respect to the Shares and, in any event, requires that the Shares be held for a minimum of six (6) months, and in certain cases one (1) year,
after they have been purchased and paid for (within the meaning of Rule 144). Optionee understands that use of a promissory note as payment for the Shares may not be deemed to be “full payment of the purchase price” within the meaning of
Rule 144 unless certain conditions are met and that, accordingly, the Rule 144 holding period of such Shares may not begin to run until such Shares are fully paid for within the meaning of Rule 144. Optionee understands that Rule 144 may
indefinitely restrict transfer of the Shares so long as Optionee remains an “affiliate” of the Company or if “current public information” about the Company (as defined in Rule 144) is not publicly available. Optionee understands
that, in the case of securities to which Rule 144 is not applicable, compliance with some other exemption under the Securities Act will be required. 

(e)    Tax Consequences. Optionee acknowledges that there may be adverse tax consequences upon
exercise of this Option or disposition of the Shares, and that Optionee should consult a tax adviser prior to such exercise or disposition. Optionee acknowledges that the Exercise Price has been determined by the Administrator based upon the best
evidence available to the Administrator and is intended to equal the Fair Market Value of the Shares as of the date of grant, or in some cases 110% of Fair Market Value, as required by the Code. However, the tax treatment of this Option is not
guaranteed. Optionee agrees to bear the entire risk of adverse tax consequences if this Option Agreement is later determined to be have been granted at below Fair Market Value and acknowledges and agrees that neither the Company, the Administrator
nor any of their designees shall be liable for any taxes, penalties or other monetary amounts owed by the Optionee, employee, beneficiary or other person as a result of the grant, amendment, modification, exercise and/or payment of, or under, this
Option Agreement, notwithstanding any challenge made to the determination of Fair Market Value by any taxing authority. Optionee represents that prior to purchase or disposition of the Shares, Optionee will consult with his/her own tax advisor who
Optionee deems advisable in connection with the purchase or disposition of the Shares and Optionee is not relying on the Company for any tax advice. 

(f)    Personal Data. Optionee acknowledges and agrees to the collection, use and transfer, in
electronic or other form, of Optionee’s personal data in order to implement, administer and manage the Plan. Optionee acknowledges that the Company holds certain personal information regarding the Optionee (including, but not limited to, name,
home address and telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all Awards or any other
entitlement to Shares awarded, cancelled, purchased, exercised, vested, unvested or outstanding in Optionee’s favor (“Data”). Optionee acknowledges that the Data may be transferred to any third-parties assisting in the
implementation, administration and management of the Plan, that third-parties may be located in the United States or elsewhere. Optionee authorizes recipients of the Data to receive, possess, use, retain and transfer the Data, in electronic or other
form, for the purposes of implementing, administering and managing Optionee’s participation in the Plan, including any requisite transfer of such Data, as may be required to a broker or other third party with whom Optionee may elect to deposit
any Shares acquired under the Plan. Optionee understands that the Data will be held only as long as is necessary to implement, administer and manage participation in the Plan. Optionee understands that he/she may view his/her Data, request
additional information about the storage and processing of the Data, require any necessary amendments to the Data or refuse or withdraw the consents herein, in any case without cost, by contacting the Administer in writing. Optionee understands that
refusing or withdrawing consent may affect Optionee’s ability to participate in the Plan. 







 7.    Transfer Limitations. 

(a)    General. The Optionee shall not assign, encumber or dispose of any interest in Shares acquired
pursuant to the exercise of this Option other than in compliance with the provisions of this Section 7 and Section 6(b) hereof. 

(b)    Right of First Refusal. The Shares acquired pursuant to the exercise of this Option may be sold by
the Optionee only in compliance with the provisions of this Section 7(b), and subject in all cases to compliance with the provisions of Section 6(b) hereof. 

(i)    Prior to any intended sale, Optionee shall first give written notice (the “Offer Notice”)
to the Company specifying (A) his or her bona fide intention to sell or otherwise transfer such Shares, (B) the name and address of the proposed purchaser(s), (C) the number of Shares the Optionee proposes to sell (the
“Offered Shares”), (D) the price for which he or she proposes to sell the Offered Shares, and (E) all other material terms and conditions of the proposed sale. 

(ii)    Within thirty (30) days after receipt of the Offer Notice, the Company or its nominee(s) may elect to
purchase all or any portion of the Offered Shares at the price and on the terms and conditions set forth in the Offer Notice by delivery of written notice (the “Acceptance Notice”) to the Optionee specifying the number of Offered
Shares that the Company or its nominees elect to purchase. Within fifteen (15) days after delivery of the Acceptance Notice to the Optionee, the Company and/or its nominee(s) shall deliver to the Optionee payment of the amount of the purchase
price of the Offered Shares to be purchased pursuant to this Section 7(b), against delivery by the Optionee of a certificate or certificates representing the Offered Shares to be purchased, duly endorsed for transfer to the Company or such
nominee(s), as the case may be. Payment shall be made on the same terms as set forth in the Offer Notice or, at the election of the Company or its nominees(s), by check or wire transfer of funds. If the Company and/or its nominee(s) do not elect to
purchase all of the Offered Shares, the Optionee shall be entitled to sell the balance of the Offered Shares to the purchaser(s) named in the Offer Notice at the price specified in the Offer Notice or at a higher price and on the terms and
conditions set forth in the Offer Notice; provided, however, that such sale or other transfer must be consummated within sixty (60) days from the date of the Offer Notice and any proposed sale after such sixty (60) day period may be made
only by again complying with the procedures set forth in this Section 7(b). 
 (iii)    The Optionee may
transfer all or any portion of the Shares during Optionee’s lifetime or on Optionee’s death by will or intestacy to Optionee’s Immediate Family or to a trust for the benefit of Optionee or Optionee’s Immediate Family without such
transfer being subject to the “right of first refusal” (the “Right of First Refusal”) set forth in this Section 7(b). “Immediate Family” as used herein shall mean spouse, lineal descendant or
antecedent, father, mother, brother or sister or a person registered with the state of his or her residence as a same-sex domestic partner or a person deemed to be a spousal equivalent for whom the following
circumstances are true: (A) irrespective of whether or not the Optionee and the spousal equivalent are the same sex, they are the sole spousal equivalent of the other for the last twelve (12) months, (B) they intend to remain so
indefinitely, (C) neither are married to anyone else, (D) both are at least 18 years of age and mentally competent to consent to contract, (E) they are not related by blood to a degree of closeness that which would prohibit legal
marriage in the state in which they legally reside, (F) they are jointly responsible for each other’s common welfare and financial obligations, and (G) they reside together in the same residence for the last twelve (12) months
and intend to do so indefinitely. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Option Agreement, and there shall be no further transfer of such Shares except in
accordance with the terms of this Section 7. 







 (c)    Involuntary Transfers. In the event of any transfer by
operation of law or other involuntary transfer (including death or divorce, but excluding in the event of death a transfer to Immediate Family as set forth in Section 7(b)(iii)) of all or a portion of the Shares by the record holder thereof,
the Company shall have the right to purchase any or all of the Shares transferred at purchase price equal to the Fair Market Value (as determined in accordance with the Plan) of the Shares on the date of transfer. In the event of a transfer
contemplated by this Section 7(c), the transferee shall promptly notify the Company of the occurrence of such transfer. The Company’s right to purchase Shares under this Section shall commence upon the date of the transfer and shall
continue until thirty (30) days following receipt by the Company of written notice of the occurrence of such transfer from the transferee. 

(d)    Binding on Successors and Transferees. Any Successor of Optionee pursuant to Section 5 hereof,
and any transferee of the Shares pursuant to this Section 7, shall hold the Shares subject to the terms and conditions of this Option Agreement and no further transfer of the Shares may be made without complying with the provisions of this
Section 7. 
 (e)    Termination of Rights. The rights provided the Company and its nominee(s) under
this Section 7 shall terminate upon the closing of the initial public offering of shares of the Company’s Common Stock pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under
the Securities Act. 
 (f)    Assignment of Rights. The Company may assign its rights under this
Section 7 without the consent of the Optionee. 
 8.    Restrictive Legends. 

(a)    Optionee hereby acknowledges that federal securities laws and the securities laws of the state in which he
or she resides may require the placement of certain restrictive legends upon the Shares issued upon exercise of this Option. Optionee 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 Company or by state or federal securities laws: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933; THEY HAVE BEEN ACQUIRED BY THE
HOLDER FOR INVESTMENT AND MAY NOT BE PLEDGED, HYPOTHECATED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT AS MAY BE AUTHORIZED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER.” 

(b)    In addition, all stock certificates evidencing the Shares shall be imprinted with a legend substantially as
follows: 
 “THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST
REFUSAL IN FAVOR OF THE CORPORATION AND/OR ITS NOMINEE(S). AS SET FORTH IN A STOCK OPTION AGREEMENT, TRANSFER OF THESE SHARES MAY BE MADE ONLY IN COMPLIANCE WITH THE PROVISIONS OF SAID AGREEMENT, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF
SAID CORPORATION. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.” 







 9.    Adjustments Upon Changes in Capital Structure.
This Option shall be subject to Section 4.2 of the Plan. 
 10.    Change in Control. This
Option shall be subject to Section 9.1 of the Plan. In addition, following a Change in Control in which this Option is assumed pursuant to Section 9.1(c) of the Plan, this Option or any New Incentives, as the case may be, shall continue to
vest in accordance with the provisions of Section 2 hereof and shall continue in effect for the remainder of the term of this Option in accordance with the provisions of Section 3 hereof. However, in the event of a Change in Control, the
vesting of this Option or the New Incentives, as the case may be, shall accelerate automatically and vest in full effective upon the first to occur of (a) the first anniversary of the closing of such Change in Control, or (b) an
Involuntary Termination (as defined below) of Optionee’s Continuous Service following such Change in Control. 
 For purposes of this
Section 10, “Involuntary Termination” shall mean the termination of Optionee’s Continuous Service by reason of: 

(i)    Optionee’s involuntary dismissal or discharge by the Company, or by the acquiring or successor entity
(or parent or any subsidiary thereof employing the Optionee) for reasons other than Cause; or 

(ii)    Optionee’s voluntary resignation following (x) a change in Optionee’s position with the
Company, or the acquiring or successor entity (or parent or any subsidiary thereof) which materially reduces Optionee’s duties and responsibilities or the level of management to which Optionee reports; (y) a reduction in Optionee’s
level of compensation (including base salary, fringe benefits and target bonus under any performance based bonus or incentive programs) by more than ten percent (10%); or (z) a relocation of Optionee’s principal place of employment by more
than thirty (30) miles; provided and only if such change, reduction, or relocation is effected without Optionee’s written consent. 

11.    Limitation of Company’s Liability for Nonissuance. The Company agrees to use its
reasonable best efforts to obtain from any applicable regulatory agency such authority or approval as may be required in order to issue and sell the Shares to the Optionee pursuant to this Option. Inability of the Company to obtain, from any such
regulatory agency, authority or approval deemed by the Company’s counsel to be necessary for the lawful issuance and sale of the Shares hereunder and under the Plan shall relieve the Company of any liability in respect of the nonissuance or
sale of such shares as to which such requisite authority or approval shall not have been obtained. 

12.    No Retention Rights. Nothing in this Option Agreement shall obligate the Company or any
Affiliated Company, or their respective stockholders, directors, officers or employees, to continue any relationship that Optionee might have as a director, employee, Consultant or other Service Provider of the Company. The right of the Company or
any Affiliated Company to terminate at will Optionee’s employment at any time (whether by dismissal, discharge or otherwise), with or without Cause, is specifically reserved. Moreover, the Optionee acknowledges and agrees that the vesting of
right to exercise the Option pursuant to this Option Agreement is earned only by continuing service as a service provider at will. The Optionee further acknowledges and that this Option Agreement, the transactions contemplated hereunder and the
vesting schedule, if any, do not constitute an express or implied promise of continued employment or engagement as a service provider for the vesting period, or for any period at all, and shall not interfere with the Optionee’s right or the
Company’s or Affiliated Company’s right to terminate the Optionee’s relationship with the Company or Affiliated Company at any time, with or without Cause or notice. 







 13.    Rights as Stockholder. The Optionee (or
transferee of this option by will or by the laws of descent and distribution) shall have no rights as a stockholder with respect to any Shares covered by this Option until such person has duly exercised this Option, paid the Exercise Price, and
become a holder of record of the Shares purchased. 
 14.    “Market Stand-Off” Agreement. In connection with any underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under
the Securities Act, including the Company’s initial public offering, the Optionee or a transferee shall not directly or indirectly sell, make any short sale of, loan, hypothecate, pledge, offer, grant or sell any option or other contract for
the purchase of, purchase any option or other contract for the sale of, or otherwise dispose of or transfer, or agree to engage in any of the foregoing transactions with respect to, any Shares without the prior written consent of the Company or its
managing underwriter. Such restriction (the “Market Stand-Off”) shall be in effect for such period of time following the date of the final prospectus for the offering as may be requested by
the Company or such underwriter. In no event, however, shall such period exceed 180 days plus such additional period as may reasonably be requested by the Company or such underwriter to accommodate regulatory restrictions on (i) the publication
or other distribution of research reports or (ii) analyst recommendations and opinions, including (without limitation) the restrictions set forth in Rule 2711(f)(4) of the National Association of Securities Dealers and Rule 472(f)(4)
of the New York Stock Exchange, as amended, or any similar successor rules promulgated by the Financial Industry Regulatory Authority, Inc. In the event of the declaration of a stock dividend, a spin off, a stock split, an adjustment in conversion
ratio, a recapitalization or a similar transaction affecting the Company’s outstanding securities without receipt of consideration, any new, substituted or additional securities which are by reason of such transaction distributed with respect
to any Shares subject to the Market Stand-Off, or into which such Shares thereby become convertible, shall immediately be subject to the Market Stand-Off. Optionee or
transferee further agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In addition,
if reasonably requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Optionee or transferee 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. In order to enforce the Market Stand-Off, the Company may impose stop-transfer instructions with respect to the Shares acquired under this Option Agreement until the end of the applicable stand-off period.
The Company’s underwriters shall be beneficiaries of the agreement set forth in this Section 14. 

15.    Interpretation. This Option is granted pursuant to the terms of the Plan, and shall in all
respects be interpreted in accordance therewith. To the extent of any conflict or ambiguity between the terms of the this Option Agreement and the Plan, the terms of the Plan shall govern, and the Administrator shall interpret and construe this
Option Agreement and the Plan, and any action, decision, interpretation or determination made in good faith by the Administrator shall be final and binding on the Company and the Optionee. 

16.    Notices. Any notice, demand, offer, request or other communication required or permitted to be
given by either the Company or the Optionee pursuant to the terms of this Option Agreement shall be in writing and shall be deemed effectively given the earlier of (a) when received, (b) when delivered personally, (c) one business day
after being delivered by facsimile (with receipt of appropriate confirmation), (d) one business day after being deposited with an overnight courier service, or (e) four days after being deposited in the U.S. mail, First Class with postage
prepaid and return receipt requested, and addressed to the parties at the addresses provided to the Company (which the Company agrees to disclose to the other parties upon request) or such other address as a party may request by notifying the other
in writing. 







 17.    Governing Law. The validity, construction,
interpretation, and effect of this Option shall be governed by and determined in accordance with the laws of the State of Delaware. 

18.    Severability. Should any provision or portion of this Option Agreement be held to be
unenforceable or invalid for any reason, the remaining provisions and portions of this Option Agreement shall be unaffected by such holding.

NOTICE OF EXERCISE OF 

STOCK OPTION AND INVESTMENT REPRESENTATIONS 

Name of Optionee:
                                        








 Crinetics Pharmaceuticals, Inc. 

                          
               

                          
               
 Attention: President 

Ladies and Gentlemen: 
 I hereby exercise my option (the
“Option”) to purchase shares of Common Stock (the “Shares”), of Crinetics Pharmaceuticals, Inc., a Delaware corporation (the “Company”), pursuant to the Stock Option Agreement, dated
                    , 20    , granted to me under the Company’s amended and restated 2015 Stock Incentive
Plan. The number of Shares that I am purchasing at this time is set forth below, and my check payable to the Company in the amount of the Total Exercise Price is enclosed with this Notice of Exercise: 

 

					
		
	 Number of Shares purchased hereby:
	  	 	                                   
       	 
		
	 Exercise Price per Share:
	  	 	$                                   
     	 
		
	 Total Exercise Price:
	  	 	$                                   
     	 

 In connection with the exercise of my Option, I hereby represent to the Company that: 

1.    I am acquiring the Shares for my own account, for investment purposes only, and not with a view to the distribution,
resale or other disposition thereof. 
 2.    I understand that the Shares are being issued by the Company without
having first registered them under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state, on the basis of certain exemptions from such registration requirements which depend, in part,
upon the truth and accuracy of my representations made herein. 
 3.    Without in any way limiting the representations
set forth above, I agree that I will not dispose of any interest in the Shares unless and until (a) I shall have notified the Company of the proposed disposition; (b) I shall have furnished the Company with an opinion of counsel to the
effect that such disposition will not require registration under the Securities Act, and (c) such opinion of counsel shall have been concurred in by the Company’s counsel. 

4.    I acknowledge receipt of all information as I deem necessary and appropriate to enable me to evaluate the merits and
risks of my investment in the Shares, including information concerning the business and financial condition of the Company, and that I have had the opportunity to discuss such information with, and ask questions of, an officer of the Company. 

5.    I am an investor of sufficient sophistication and experience to make an informed investment decision regarding my
purchase of the Shares, and I am able to bear the economic risk of an investment in the Shares. I am aware of the highly speculative nature of the investment in the Shares; the financial hazards involved; the lack of liquidity of the Shares and the
restrictions on transferability of the Shares (e.g., that I may not be able to sell or dispose of the Shares or use them as collateral for loans); the qualifications and backgrounds of the management of the Company; and the tax consequences of
investment in the Shares. 
 6.    I recognize that the Shares must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is available, and further 







 
recognize that the Company is under no obligation to register the Shares or to comply with any exemption from such registration. 

7.    I have been advised that Rule 144 promulgated under the Securities Act, which permits certain limited sales of
unregistered securities, is not presently available with respect to the Shares and, in any event, requires that the Shares be held for a minimum of six (6) months, and in certain cases one (1) year, after they have been purchased and paid
for (within the meaning of Rule 144). I understand that use of a promissory note as payment for the Shares may not be deemed to be “full payment of the purchase price” within the meaning of Rule 144 unless certain conditions are met and
that, accordingly, the Rule 144 holding period of such Shares may not begin to run until such Shares are fully paid for within the meaning of Rule 144. I understand that Rule 144 may indefinitely restrict transfer of the Shares so long as I remain
an “affiliate” of the Company or if “current public information” about the Company (as defined in Rule 144) is not publicly available. I further understand that, in the case of securities to which Rule 144 is not applicable,
compliance with some other exemption under the Securities Act will be required.
