 OPTION TERMS AND CONDITIONS

 1. GENERAL. These Option Terms and Conditions (these “Terms”) apply to a
particular stock option grant (the “Option”) granted by NGM Biopharmaceuticals, Inc. (the “Company”), and are incorporated by reference in the Stock Option Grant Notice (the “Grant
Notice”) corresponding to that particular grant. The recipient of the Option identified in the Grant Notice is sometimes referred to as “Participant.” The effective date of grant of the Option as set forth in the
Grant Notice is referred to as the “Date of Grant”. The Option has been granted to Participant in addition to, and not in lieu of, any other form of compensation otherwise payable or to be paid to Participant. The Grant
Notice and these Terms are collectively referred to as the “Option Agreement” applicable to the Option. Capitalized terms are defined in the Plan if not defined in the Option Agreement. 

2. VESTING. The Option will vest as provided in Participant’s Grant Notice. Vesting will cease upon the
termination of Participant’s Continuous Service. 
 3. EXERCISE PRIOR TO
VESTING (“EARLY EXERCISE”). If permitted in the Grant Notice (i.e., the “Exercise Schedule” indicates “Early Exercise
Permitted”) and subject to the provisions of the Option, Participant may elect at any time that is both (i) during the period of Participant’s Continuous Service and (ii) during the term of the Option, to exercise all or part of
the Option, including the unvested portion of the Option. A partial exercise of the Option will be deemed to cover first vested shares of Common Stock and then the earliest vesting installment of unvested shares of Common Stock. Any shares of Common
Stock under the Option that have not vested as of the date of exercise will be subject to the repurchase option in favor of the Company as described in the Company’s form of Notice of Exercise. 

4. INCENTIVE STOCK OPTION TERMS. 

(a) ISO $100,000 Limit. If the Option is an Incentive Stock Option, then, to the extent that the aggregate Fair Market Value
(determined at the Date of Grant) of the shares of Common Stock with respect to which the Option plus all other Incentive Stock Options that Participant holds are exercisable for the first time by Participant during any calendar year (under all
plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), the Option(s) or portions thereof that exceed such limit (according to the order in which they were granted) will be treated as Nonstatutory Stock Options.

 (b) Notice Requirement on Sale/Transfer of Shares. If the Option is an Incentive Stock Option, by exercising the
Option Participant agrees to notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of the Option that occurs within two (2) years after the
Date of Grant or within one (1) year after such shares of Common Stock are transferred upon exercise of the Option. 
 5.
EXERCISE AND METHOD OF PAYMENT. 
 (a) Participant may
generally exercise the vested portion of the Option (and the unvested portion if permitted in Participant’s Stock Option Grant Notice, subject to Section 2 above) by delivery of payment of the exercise price and applicable withholding
taxes and other required documentation to the Stock Plan Administrator in accordance with the option exercise procedures established by the Stock Plan Administrator, which may include an electronic submission. Please review Sections 5(f), 5(j) and
10(e) of the Plan, which may restrict or prohibit Participant’s ability to exercise the Option during certain periods. Participant may exercise the Option only for whole shares of Common Stock. 












 (b) Participant may pay the exercise price by cash, check, bank draft or money order,
or any other method provided in Section 5 of the Plan if permitted by the Company at the time of exercise. 
 6.
TERM. Participant may not exercise the Option before the Date of Grant or after the expiration of the Option’s term. The term of the Option expires upon the earliest of the following: 

(a) immediately upon the termination of Participant’s Continuous Service for Cause; 

(b) three (3) months after the termination of Participant’s Continuous Service for any reason other than Cause,
Participant’s Disability, or Participant’s death; 
 (c) twelve (12) months after the termination of
Participant’s Continuous Service due to Participant’s Disability (except as otherwise provided in subsection (d)) below; 

(d) eighteen (18) months after Participant’s death if Participant dies either during Participant’s Continuous Service or
within three (3) months after Participant’s Continuous Service terminates for any reason other than Cause; 
 (e) the
Expiration Date indicated in Participant’s Grant Notice; and 
 (f) the day before the tenth (10th) anniversary of the Date of
Grant. 
 Notwithstanding the foregoing, if Participant dies during the period provided in subsections (b) or (c) above, the term of
the Option shall not expire until the earlier of (i) eighteen months after Participant’s death, (ii) any termination of the Option in connection with a Change in Control, (iii) the Expiration Date indicated in the Grant Notice,
or (iv) the day before the tenth anniversary of the Date of Grant. Additionally, the post-termination exercise period of the Option may be extended as provided in Section 5(f) of the Plan. 

If the Option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the Date of Grant and ending on the day three (3) months before the date of exercise, Participant must be an employee of the Company or an Affiliate, except in the event of Participant’s
death or Disability. 
 7. TRANSFERABILITY. Except as otherwise provided in the Plan, the Option is not
transferable, except by will or by the laws of descent and distribution, and is exercisable during Participant’s life only by Participant. 

8. RESPONSIBILITY FOR TAXES. 

(a) Participant may not exercise the Option unless the Tax-Related Items of the Company and/or
any Affiliate, including Participant’s employer are satisfied. By accepting the Option, Participant agrees that the Company or an Affiliate may satisfy any applicable tax withholding obligations for
Tax-Related Items at its sole election as provided in Section 8 of the Plan. Further, if Participant is subject to Tax-Related Items in more than one jurisdiction,
Participant acknowledges that the Company and/or an Affiliate may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 

  
 2. 













 (b) Neither the Company nor any Affiliates make any representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, and are under no obligation to structure the Option to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Participant acknowledges that, regardless of any action the Company or any Affiliate takes with respect to any or all
Tax-Related Items, the ultimate liability for all Tax-Related Items is and remains Participant’s responsibility and may exceed the amount actually withheld by the
Company or an Affiliate. In the event that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, Participant agrees to indemnify and hold the Company harmless from any failure by the Company to
withhold the proper amount. Participant further acknowledges and agrees not to make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates for Tax-Related Items arising from
the Option. 
 9. NOTICES. Any notice or request required or permitted in the plan or this
Option Agreement (including any attachments) will be given in writing to each of the other parties hereto and will be deemed effectively given on the earlier of (i) the date of personal delivery, including delivery by express courier, or
delivery via electronic means, or (ii) the date that is five (5) days after deposit in the United States Post Office (whether or not actually received by the addressee), by registered or certified mail with postage and fees prepaid,
addressed to the Company at its primary executive offices, attention: Stock Plan Administrator, and addressed to Participant at the address as on file with the Company at the time notice is given. 

10. GOVERNING PLAN DOCUMENT. The Option is subject to all the
provisions of the Plan, including but not limited to the general provisions in Section 9 of the Plan, and the provisions in Section 10 of the Plan regarding the impact of certain transactions on the Option. The Option is further subject to
all interpretations, amendments, rules and regulations, which may be adopted from time to time, pursuant to the Plan. If there is any conflict between the provisions of the Option and those of the Plan, the provisions of the Plan will control. 

11. GOVERNING LAW. The interpretation, performance and enforcement of
this Option Agreement will be governed by the law of the State of Delaware without regard to that state’s conflicts of laws rules.

income taxation in the United States, the acquisition of Unvested Shares may result in adverse tax consequences which may be avoided or mitigated by filing an election under Section 83(b) of the Code. Such election must be filed within thirty
(30) days after the Unvested Shares are transferred to the Purchaser. A sample of the form for making the Code Section 83(b) election attached to the Notice of Exercise as Exhibit B. I
acknowledge that I have been advised to consult with my own tax advisor to determine the tax consequences of acquiring the Unvested Shares and the advantages and disadvantages of filing the Code Section 83(b) election. I acknowledge that it is
my sole responsibility, and not the Company’s or its’ legal counsel’s, to file a timely election under Code Section 83(b), even if the Company or its representatives agree to make this filing on my behalf.

listed above (whether vested or unvested), which are being acquired by me for my own account upon exercise of the option as set forth above: 
  

	 	•	 	 I acknowledge that the Unvested Shares have not been registered under the Securities Act of 1933, as amended (the
“Securities Act”), and are deemed to constitute “restricted securities” under Rule 144 promulgated under the Securities Act. I represent and warrant to the Company that I have no present intention of distributing or
selling the Shares except as permitted under the Securities Act and any applicable state securities laws. 


  

	 	•	 	 I further acknowledge that the Unvested Shares may not be sold, assigned, transferred, pledged or otherwise
disposed of, alienated or encumbered, either voluntarily or involuntarily, other than by will or the laws of descent and distribution, until the time that the Unvested Shares become vested in accordance with the terms of the Option Agreement.



  

	 	•	 	 I further acknowledge that certificates (if any) representing any of the Shares subject to the provisions of the
Option will have endorsed thereon appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to applicable securities laws. 



4. Entire Agreement. I acknowledge that this Notice of Exercise (including Exhibit A), together with the Option Agreement
and the Plan, set forth the entire understanding between myself and the Company regarding the acquisition of Shares referenced above and supersedes all prior oral and written agreements, promises and/or representations on that subject.

 EXHIBIT A TO NOTICE OF
EXERCISE 
 COMPANY REPURCHASE RIGHT ON
UNVESTED SHARES 
 Subject to the terms and conditions of this Exhibit A to the Notice of Exercise,
the Company shall have the right (the “Repurchase Right”) (but not the obligation) to repurchase in one or more transactions in connection with the termination of Purchaser’s Continuous Service, and Purchaser (or any
permitted transferee) shall be obligated to sell any of the Unvested Shares that have not, as of Purchaser’s date of termination, become vested. 

1. To exercise the Repurchase Right, the Company must give written notice thereof to Purchaser (the “Repurchase
Notice”). The Repurchase Notice is irrevocable by the Company and must (a) be in writing and signed by an authorized officer of the Company, (b) set forth the Company’s intent to exercise the Repurchase Right and contain
the total number of Unvested Shares to be sold to the Company pursuant to the exercise of the Repurchase Right, (c) be delivered to Purchaser in person or by fax or electronic mail (transmission confirmed), or by overnight courier service,
postage prepaid, addressed to Purchaser at Purchaser’s address reflected or last reflected on the Company’s payroll records, and (d) be so mailed or delivered no later than 90 days after the date of Purchaser’s termination of
Continuous Service. The Repurchase Notice shall be deemed to have been duly given as of the date mailed or delivered in accordance with the foregoing provisions. 

2. The price per Unvested Share to be paid by the Company upon settlement of the Repurchase Right (the “Repurchase
Price”) shall equal the lesser of (a) the price paid by the Purchaser to exercise the Option and acquire such Unvested Share, or (b) the Fair Market Value of a Share determined as of the date of the Repurchase Notice in
accordance with the terms of the Plan. No interest shall be paid with respect to and no other adjustments (other than adjustments in accordance with the Plan to reflect stock splits and similar changes in capitalization) shall be made to the
Repurchase Price. The closing of any repurchase pursuant to the Repurchase Right shall be at a date to be specified by the Company, such date to be no later than 90 days after the date of Purchaser’s termination of Continuous Service. The
Repurchase Price shall be paid at the closing in the form of a check or by cancellation of indebtedness. 
 3. Upon a repurchase of any
Unvested Shares by the Company, such repurchased Unvested Shares shall be automatically transferred to the Company, without any further action by Purchaser (or Purchaser’s beneficiary or personal representative, as the case may be). Purchaser
(or Purchaser’s beneficiary or personal representative, as the case may be) shall deliver any additional documents of transfer that the Company may request to confirm the transfer of such repurchased Unvested Shares to the Company. 

4. To the maximum extent permitted by law, Purchaser’s rights following the exercise of the Repurchase Right shall, with respect to the
repurchase and the Unvested Shares covered thereby, be solely the rights that he or she has as a general creditor of the Company to receive payment of the amount specified above. 












 EXHIBIT B TO NOTICE OF
EXERCISE 
 SECTION 83(B) ELECTION 












 INSTRUCTIONS FOR FILING
SECTION 83(b) ELECTION 
 Attached is a form of election under Section 83(b) of the Internal
Revenue Code and an accompanying IRS cover letter. Please fill in your social security number1 and sign the election and cover letter, then proceed as follows: 

 

	(a)	 Make three copies of the completed election form and one copy of the IRS cover letter.



  

	(b)	 Send the original signed election form and cover letter, the copy of the cover letter, and
a self-addressed stamped return envelope to the Internal Revenue Service Center where you would otherwise file your tax return23. Even if an
address for an Internal Revenue Service Center is already included in the forms below, it is your obligation to verify such address. This can be done by searching for the term “where to file” on www.irs.gov or by calling 1 (800) 829-1040. 


 Sending the election via certified mail, requesting a return receipt, with
the certified mail number written on the cover letter is also recommended. 
  

	(c)	 Deliver one copy of the completed election form to NGM Pharmaceutials, Inc. 



 

	(d)	 Applicable state law may require that you attach a copy of the completed election form to your state personal
income tax return(s) when you file it for the year (assuming you file a state personal income tax return).4 



Please consult your personal tax advisor(s) to determine whether or not a copy of this Section 83(b) election should be filed with your
state personal income tax return(s). 
  

	(e)	 Retain one copy of the completed election form for your personal permanent records. 



 

	1 	 Note: If you do not have a taxpayer ID number (TIN), put “None –non-US taxpayer” and include in the cover letter to the IRS a statement explaining that the Section 83(b) election is being filed because the individual may become a US taxpayer before the stock
vests. If the individual is applying for a TIN, instead include “applied for” and enclose a copy of the W-7 application. Note that there may be important factors to consider before applying for a
TIN, including immigration status, etc. 



	2 	 Note: Per Treasury Regulation § 1.83-2(c),
the Section 83(b) election must be filed with the IRS office where the person otherwise files his or her tax return. Assuming these are individual taxpayers who would file a Form 1040, see http://www.irs.gov/uac/Where-to-File-Addresses-for--Taxpayers-and--Tax-Professionals-Filing-Form-1040
. Use the address in the row which includes the state in which the service provider lives and in the column entitled “And you ARE NOT enclosing a payment”.




	3 	 Note: Per Treasury Regulation § 1.83-2(c), the
Section 83(b) election must be filed with the IRS office where the person otherwise files his or her tax return. As of October 2018, if you live in a foreign country or are a dual status alien (foreigners that will have lived both in their home
country and the United States during the year in which they make the election) you should send the 83(b) election to Austin, TX 73301-0215. You can verify this is still the correct address at: http://www.irs.gov/uac/Where-to-File-Addresses-for--Taxpayers-and--Tax-Professionals-Filing-Form-1040
. 



	4 	 Note: Pursuant to Treasury Regulations finalized in July 2016 (Treas. Reg. § 1.83-2(c); T.D. 9779), taxpayers are no longer required to submit a copy of a Code Sec. 83(b) election with their federal personal income tax returns for the year in which the property subject to the
election was transferred. However, you are strongly encouraged to retain a copy of the completed election form and the IRS filed-stamped copy of your cover letter along with a copy of the federal personal income tax return for the year in which the
property subject to the election was transferred for your personal permanent records in case you ever need to demonstrate proper and timely filing. 














 Note: An additional copy of the completed election form must be delivered to the transferee
(recipient) of the property if the service provider and the transferee are not the same person. 
 Please note that the election must be filed with
the IRS within 30 days of the date of the Option exercise. Failure to file within that time will render the election void and you may recognize ordinary taxable income or alternative minimum taxable income, as applicable, as your vesting
restrictions lapse. The Company and its counsel cannot assume responsibility for failure to file the election in a timely manner under any circumstances.
