WARRANT TO PURCHASE 67,200 SHARES OF COMMON STOCK 

June 6, 1995 
 THIS CERTIFIES THAT, for value
received, Lease Management Services, Inc., (“Holder”) is entitled to subscribe for and purchase Sixty Seven Thousand Two Hundred (67,200) shares of the fully paid and nonassessable Common Stock (“the Shares”) of FIBROGEN,
INC., a Delaware corporation (the “Company”), at the Warrant Price (as hereinafter defined), subject to the provisions and upon the terms and conditions hereinafter set forth. As used herein, the term “Common Stock” shall
mean the Company’s presently authorized Common Stock, and any stock into which such Common Stock may hereafter be exchanged. 

1.    Warrant Price. The Warrant Price shall initially be One & 25/100 Dollars ($1.25) per share, subject to adjustment as
provided in Section 7 below. 
 2.    Conditions to Exercise. The purchase right represented by this Warrant may be
exercised at any time, or from time to time, in whole or in part during the term commencing on the date hereof and ending on the earlier of: 

(a)    5:00 P.M. California time on the sixth annual anniversary of this Warrant Agreement; or 

(b)    the effective date of the merger of the Company with or into, the consolidation of the Company with, or the sale by
the Company of all or substantially all of its assets to another corporation or other entity (other than such a transaction wherein the shareholders of the Company retain or obtain a majority of the voting capital stock of the surviving,
resulting, or purchasing corporation); provided that the Company shall notify the registered Holder of this Warrant of the proposed effective date of the merger, consolidation, or sale at least 60 days prior to the effectiveness thereof. 

In the event that, although the Company shall have given notice of a transaction pursuant to subparagraph (b) hereof, the transaction
does not close on approximately the day specified by the Company, unless otherwise elected by the Holder any exercise of the Warrant subsequent to the giving of such notice shall be rescinded and the Warrant shall again be exercisable until
terminated in accordance with this Paragraph 2. 
 3.    Method of Exercise: Payment; Issuance of Shares; Issuance of New
Warrant. 
 (a)    Cash Exercise. Subject to Section 2 hereof, the purchase right represented by this Warrant may be
exercised by the Holder hereof, in whole or in part, by the surrender of this Warrant (with a duly executed Notice of Exercise in the form attached hereto) at the principal office of the Company (as set forth in Section 18 below) and by payment
to the Company, by check, of 







 LMSI/FIBROGEN, INC. Warrant 

Page 2 of 7 
 an amount equal to the then applicable Warrant
Price per share multiplied by the number of shares then being purchased. In the event of any exercise of the rights represented by this Warrant, certificates for the shares of stock so purchased shall be in the name of, and delivered to, the Holder
hereof, or as such Holder may direct (subject to the terms of transfer contained herein and upon payment by such Holder hereof of any applicable transfer taxes). Such delivery shall be made within 10 days after exercise of the Warrant and at
the Company’s expense and, unless this Warrant has been fully exercised or expired, a new Warrant having terms and conditions substantially identical to this Warrant and representing the portion of the Shares, if any, with respect to which this
Warrant shall not have been exercised, shall also be issued to the Holder hereof within 10 days after exercise of the Warrant. 

(b)    Net Issue Exercise. In lieu of exercising this Warrant pursuant to Section 3(a), Holder may elect to receive
shares equal to the value of this Warrant (or of any portion thereof remaining unexercised) by surrender of this Warrant at the principal office of the Company together with notice of such election, in which event the Company shall issue to Holder
the number of shares of the Company’s Common Stock computed using the following formula: 
 X = Y (A-B) 

A 
 Where X = the number of
shares of Common Stock to be issued to Holder. 
 Y = the number of shares of Common Stock purchasable under this Warrant (at the date of
such calculation). 
 A = the fair market value of one share of the Company’s Common Stock (at the date of such calculation). 

B = Warrant exercise price (as adjusted to the date of such calculation). 

(c)    Fair Market Value. For purposes of this Section 3, Fair Market Value of one share of the Company’s Common Stock
shall mean: 
 (i)    In the event of an Initial Public Offering, the per share Fair Market Value for the Common Stock
shall be the Offering Price at which the underwriters sell Common Stock to the public; or 
 (ii)    If the Common Stock
is traded on NASDAQ or Over-The-Counter or on an exchange, the per share Fair Market Value for the Common Stock will be the average of the closing bid and asked prices of the Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed, whichever is applicable, as published in the Western Edition of The Wall Street Journal for the ten (10) trading days prior to the date of determination of Fair
Market Value; or 
 (iii)    If the Company shall be subject to a merger, acquisition or other consolidation in which the
Company is not the surviving entity, pursuant to Section 2(b), the per share Fair Market Value for the Common Stock shall be the value received per share of Common Stock by all holders of the Common Stock as determined by the Board of
Directors; or 
 (iv)    In any other instance, the per share Fair Market Value for the Common Stock shall be as
determined by the Board of Directors in its reasonable business judgment. 

  
 2. 








 LMSI/FIBROGEN, INC. Warrant 

Page 3 of 7 
 In the event of 3(c)(iii)
or 3(c)(iv), above, the Company’s Board of Directors shall prepare a certificate, to be signed by an authorized Officer of the Company, setting forth in reasonable detail the basis for and method of determination of the per share
Fair Market Value of the Common Stock. The Board will also certify to the Holder that this per share Fair Market Value will be applicable to all holders of the Company’s Common Stock. Such certification must be made to Holder at least
thirty (30) business days prior to the proposed effective date of the merger, consolidation, sale, or other triggering event as defined in 3(c)(iii) and 3(c)(iv). 

(d)    Automatic Exercise. To the extent this Warrant is not previously exercised, it shall be automatically exercised in
accordance with Sections 3(b) and 3(c) hereof (even if not surrendered) immediately before: (i) its expiration, or (ii) the consummation of any consolidation or merger of the Company, or any sale or transfer of a majority of a
company’s assets pursuant to Section 2(b). 
 4.    Representations and Warranties of Holder and Restrictions on Transfer
Imposed by the Securities Act of 1933. 
 (a)    Representations and Warranties by Holder. The Holder represents and warrants
to the Company with respect to this purchase as follows: 
 (i)    The Holder has substantial experience in evaluating
and investing in private placement transactions of securities of companies similar to the Company so that the Holder is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its interests. 

(ii)    The Holder is acquiring the Warrant and the Shares of Common Stock issuable upon exercise of the Warrant
(collectively the “Securities”) for investment for its own account and not with a view to, or for resale in connection with, any distribution thereof. The Holder understands that the Securities have not been registered under the Act by
reason of a specific exemption from the registration provisions of the Act which depends upon, among other things, the bona fide nature of the investment intent as expressed herein. In this connection, the Holder understands that, in the view of the
Securities and Exchange Commission (the “SEC”), the statutory basis for such exemption may be unavailable if this representation was predicated solely upon a present intention to hold the 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 year or any other fixed period in the future.

(iii)    The Holder acknowledges that the Securities must be held indefinitely unless subsequently registered under the Act
or an exemption from such registration is available. The Holder is aware of the provisions of Rule 144 promulgated under the Act (“Rule 144”) which permits limited resale of securities purchased in a private placement subject to the
satisfaction of certain conditions, including, in case the securities have been held for less than three years, the existence of a public market for the shares, the availability of certain public information about the Company, the resale occurring
not less than two years after a party has purchased and paid for the security to be sold, the sale being through a “broker’s transaction” or in a transaction directly with a “market maker” (as provided by Rule 144(f))
and the number of shares or other securities being sold during any three-month period not exceeding specified limitations: 

(iv)    The Holder further understands that at the time the Holder wishes to sell the Securities there may be no public
market upon which such a sale may be effected, and 

  
 3. 








 LMSI/FIBROGEN, INC. Warrant 

Page 4 of 7 
 that even if such a public market
exists, the Company may not be satisfying the current public information requirements of Rule 144, and that in such event, the Holder may be precluded from selling the Securities under Rule 144 unless a) a three-year minimum holding period has
been satisfied and b) the Holder was not at the time of the sale nor at any time during the three-month period prior to such sale an affiliate of the Company.

(v)    The Holder has had an opportunity to discuss the Company’s business, management and financial affairs with its
management and an opportunity to review the Company’s facilities. The Holder understands that such discussions, as well as the written information issued by the Company, were intended to describe the aspects of the Company’s business
and prospects which it believes to be material but were not necessarily a thorough or exhaustive description. 
 (b)    Legends.
Each certificate representing the Securities shall be endorsed with the following legend: 
 THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A “NO ACTION” LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH TRANSFER, A TRANSFER MEETING
THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND EXCHANGE COMMISSION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH REGISTRATION. 

The Company need not register a transfer of Securities unless the conditions specified in the foregoing legend are satisfied. The Company may also instruct
its transfer agent not to register the transfer of any of the Shares unless the conditions specified in the foregoing legend are satisfied. 

(c)    Removal of Legend and Transfer Restrictions. The legend relating to the Act endorsed on a certificate pursuant to
paragraph 4(b) of this Warrant and the stop transfer instructions with respect to the Securities represented by such certificate shall be removed and the Company shall issue a certificate without such legend to the Holder of the Securities
if (i) the Securities are registered under the Act and a prospectus meeting the requirements of Section 10 of the Act is available or (ii) the Holder provides to the Company an opinion of counsel for the Holder reasonably satisfactory
to the Company, or a no-action letter or interpretive opinion of the staff of the SEC reasonably satisfactory to the Company, to the effect that public sale, transfer or assignment of the Securities may be without registration and without compliance
with any restriction such as Rule 144. 
 5.    Condition of Transfer or Exercise of Warrant. It shall be a condition to any
transfer or exercise of this Warrant that at the time of such transfer or exercise, the Holder shall provide the Company with a representation in writing that the Holder or transferee is acquiring this Warrant and the shares of Common
Stock to be issued upon exercise, for investment purposes only and not with a view to any sale or distribution, or a statement of pertinent facts covering any proposed distribution. As a further condition to any transfer of this Warrant or any or
all of the shares of Common Stock issuable upon exercise of this Warrant, other than a transfer registered under the Act, the Company must have received a legal opinion, in form and substance satisfactory to the Company and its counsel,
reciting the pertinent circumstances surrounding the proposed transfer and stating that such transfer is exempt from the registration and prospectus delivery requirements of the Act. Each certificate evidencing the shares issued


  
 4. 








 LMSI/FIBROGEN, INC. Warrant 

Page 5 of 7 
 upon exercise of the Warrant or upon any-transfer
of the shares (other than a transfer registered under the Act or any subsequent transfer of shares so registered) shall, at the Company’s option, contain a legend in form and substance satisfactory to the Company and its counsel,
restricting the transfer of the shares to sales or other dispositions exempt from the requirements of the Act. 
 As further condition to
each transfer, the transferee shall receive and accept a Warrant, of like tenor and date, executed by the Company. 
 6.    Stock
Fully Paid; Reservation of Shares. All Shares which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all taxes, liens, and charges with respect to
the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for issuance upon exercise of the purchase rights evidenced by this Warrant, a
sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. 

7.    Adjustment for Certain Events. In the event of changes in the outstanding Common Stock by reason of stock dividends,
split-ups, recapitalizations, reclassifications, mergers, consolidations, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and
the Warrant Price shall be correspondingly adjusted, as appropriate, by the Board of Directors of the Company. The adjustment shall be such as will give the Holder of this Warrant upon exercise for the same aggregate Warrant Price the total
number, class and kind of shares as he would have owned had the Warrant been exercised prior to the event and had he continued to hold such shares until after the event requiring adjustment. 

8.    Notice of Adjustments. Whenever any Warrant Price shall be adjusted pursuant to Section 7 hereof, the Company shall
prepare a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Price and number
of shares issuable upon exercise of the Warrant after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by certified or registered mail, return receipt required, postage prepaid) within thirty (30) days
of such adjustment to the Holder of this Warrant as set forth in Section 18 hereof. 
 9.    “Market Stand-Off”
Agreement. Holder hereby agrees that for a period of 180 days following the effective date of the first registration statement of the Company covering common stock (or other securities) to be sold on its behalf in an underwritten public
offering, it will not, to the extent requested by the Company and any underwriter, sell or otherwise transfer or dispose of (other than to donees or transferees who agree to be similarly bound) any of the Shares at any time during such period
except common stock included in such registration; provided, however, that all officers and directors of the Company who hold securities of the Company or options to acquire securities of the Company and all other persons with registration
rights enter into similar agreements. 
 10.    Transferability of Warrant. This Warrant is transferable on the books of the
Company at its principal office by the registered Holder hereof upon surrender of this Warrant properly endorsed, subject to compliance with applicable federal and state securities laws. The Company shall issue and deliver to the
transferee a new Warrant representing the Warrant so transferred. Upon any partial transfer, the Company will issue and deliver to Holder a new Warrant with respect to the Warrant not so transferred. Holder shall not have any right to transfer any
portion of this Warrant to any direct competitor of the Company. 

  
 5. 








 LMSI/FIBROGEN, INC. Warrant 

Page 6 of 7 
 11.    No Fractional
Shares. No fractional share of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional share the Company shall make a cash payment therefor upon the basis of the Warrant Price then in effect.

 12.    Charges, Taxes and Expenses. Issuance of certificates for shares of Common Stock upon the exercise of this Warrant
shall be made without charge to the Holder for any United States or state of the United States documentary stamp tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid
by the Company, and such certificates shall be issued in the name of the Holder. 
 13.     No Shareholder Rights Until Exercise.
This Warrant does not entitle the Holder hereof to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof. 

14.    Registry of Warrant. The Company shall maintain a registry showing the name and address of the registered Holder of
this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance with its terms, at such office or agency of the Company, and the Company and Holder shall be entitled to rely in all respects, prior to written notice to the
contrary, upon such registry. 
 15.    Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft, or destruction, of indemnity reasonably satisfactory to it, and, if mutilated, upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant, having terms and conditions substantially identical to this Warrant, in lieu hereof. 

16.    Miscellaneous. 

(a)    Issue Date. The provisions of this Warrant shall be construed and shall be given effect in all respect as if

 (b)    Successors. This Warrant shall be

17.    No Impairment. The Company will not, by amendment of its Articles of Incorporation or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to
