SECURED PROMISSORY NOTE  

	$200,000.00	 	October 11, 2002

Palo Alto, California

        FOR VALUE RECEIVED, JAMES HUANG
("Borrower") an employee of CORGENTECH INC., a Delaware corporation
("Lender"), hereby unconditionally promises to pay to the order of Lender, in lawful money of the United States of America and in immediately available
funds, the principal amount of Two Hundred Thousand Dollars ($200,000.00) (the "Loan"), together with
accrued and unpaid interest thereon, each due and payable on the dates and in the manner set forth below. 

        It
is the intent of the parties that the purpose of this Secured Promissory Note ("Note") is not for consumer, family, or household
purposes. 

        1.     PRINCIPAL REPAYMENT.    The outstanding principal balance of the Loan shall be subject to scheduled amortized
repayments on the dates and in the amounts listed below; provided, however, the outstanding principal balance of the Loan plus all accrued but unpaid
interest and other charges hereunder shall be due and payable in full upon the earlier to occur of any of the following: (a) that date which is three (3) years from the date of this
Note; (b) five (5) days after either the resignation by Borrower of his employment with Lender or the termination of his employment for any or no reason whatsoever, including the death
of Borrower; or (c) any sale or transfer of all or any portion of the Pledged Collateral (as defined in Section 5) (any of the events described in clauses (a) through
(c) shall be the "Maturity Date"). Notwithstanding anything to the contrary contained herein, Borrower shall have the right to prepay all or any
part of the unpaid principal amount of this Note, together with accrued and unpaid interest thereon, without penalty or premium at any time prior to the Maturity Date.

        2.     INTEREST RATE.    Borrower further promises to pay interest on the outstanding principal amount hereof from the
date hereof until payment in full, which interest shall be payable at a fixed rate of four and one-half percent (4.50%) per annum (the "Interest
Rate") and calculated on the basis of a 365-day year for the actual number of days elapsed. Accrued and unpaid interest shall be due and payable on each of the
Repayment Dates set forth in Section 1 above. 

        3.     DEFAULT INTEREST.    If any amount payable hereunder shall not be paid when due, at the option of Lender and in
lieu of the interest payable under Section 2 above, the unpaid principal balance shall immediately begin to accrue interest at a rate equal to the Interest Rate  plus five percent (5.0%) per annum.

        4.     APPLICATION OF PAYMENTS.    Payment on this Note shall be applied first to accrued interest, and thereafter to
the outstanding principal balance hereof. Any payment due hereunder shall be paid to Lender at 1651 Page Mill Road, Palo Alto, California 94304, Attn: Chief Financial Officer, or at such other place
as Lender may designate. Any amount payable hereunder will be due and payable without set-off, deduction, or counter-claim. 

        5.     SECURITY.    This Note is made with full recourse. In addition, this Note is secured by the Pledge Collateral as
defined in that certain Stock Pledge Agreement executed by Borrower in favor of 

1

 

Lender
(as the same may from time to time be amended, modified or supplemented or restated) (the "Pledge Agreement"). 

        6.     DEFAULT AND REMEDIES.

        (a)   Default.    Each of the following events shall be an "Event of
Default" hereunder: (i) Borrower fails to pay timely any of the principal amount due under this Note on the date the same becomes due and payable or any accrued interest
or other amounts due under this Note on the date the same becomes due and payable; (ii) the breach by Borrower of any other covenant or agreement under this Note; (iii) the default by
Borrower of his obligations under the Pledge Agreement or any other instrument evidencing or securing this Note; (iv) the appointment of a receiver for any part of the Pledge Collateral, or an
assignment for the benefit of creditors by, or the commencement of any proceedings under any bankruptcy or insolvency laws by or against Borrower; or (v) the transfer, directly or indirectly,
of all or any part of the Pledged Collateral, whether by sale, assignment, mortgage or otherwise, voluntarily or involuntarily. 

        (b)   Remedies.    Upon the occurrence of an Event of Default hereunder, all unpaid principal, accrued interest and
other amounts owing hereunder shall, at the option of Lender, and, in the case of an Event of Default pursuant to Section 6(a)(iv) above, automatically, be immediately due, payable and
collectible by Lender pursuant to applicable law. Lender shall have all rights and may exercise any remedies available to it under the Pledge Agreement, at law, or in equity, successively or
concurrently. 

        (c)   Right of Set-off.    Upon the occurrence of an Event of Default under Section 6, Lender is
hereby authorized to set off and apply any and all payments by way of payroll deduction, if necessary (whether for compensation, bonus arrangements, expense reimbursement, vacation, commission payment
or otherwise) at any time held and other obligations at any time owing by Lender to or for the account of Borrower against any principal and/or interest due hereunder. 

        7.     NOTICE.    All notices or other communications required or given hereunder shall be in writing and shall be
deemed effectively given when presented personally or on the date of receipt (or refusal of delivery) if sent by courier service or U.S. mail (certified or registered, postage prepaid, return receipt
requested) to the parties at the addresses given below or such other addresses as the parties may hereafter designate in writing. The date shown on the courier's confirmation of delivery or return

        8.     MAXIMUM LEGAL RATE OF INTEREST.    All agreements between Borrower and Lender, whether now existing or hereafter
arising, are hereby limited so that in no event shall the interest charged hereunder or agreed to be paid to Lender exceed the maximum amount permissible under applicable law. Lender shall be entitled
to amortize, prorate and spread throughout the full term of this Note all interest paid or payable so that the interest paid does not exceed the maximum amount permitted by law. If Lender ever
receives interest or anything deemed interest in excess of the maximum lawful amount, an amount equal to the excessive interest shall be applied to the reduction of the principal, and if it exceeds
the unpaid balance of principal hereof, such excess shall be refunded to Borrower. If interest otherwise payable to Lender would exceed the maximum lawful amount, the interest payable shall be reduced
to the maximum amount permitted under applicable law. This section

this Note with a notation of the unpaid principal in substitution of the prior Note. Lender shall furnish to Borrower reasonable evidence that the Note was destroyed, lost or stolen and any security
or indemnity that may be reasonably required by Borrower in connection with the replacement of this Note. 

        (f)    If any provision of this Note shall be held to be invalid or unenforceable, such determination shall not affect the
remaining provisions of this Note. 

        (g)   If this Note is now, or hereinafter shall be, signed by more than one party or person, it shall be the joint and several
obligation of such parties or persons and shall be binding upon such parties and upon their respective successors and assigns.

STOCK PLEDGE AGREEMENT  

        THIS STOCK PLEDGE AGREEMENT ("Pledge Agreement") is made by JAMES
HUANG, an individual ("Pledgor"), in favor of CORGENTECH INC., a Delaware
corporation, with its principal place of business at 1651 Page Mill Road, Palo Alto, California 94304 ("Pledgee"). 

        WHEREAS, Pledgor has concurrently herewith executed that certain Secured Promissory Note (the
"Note") in favor of Pledgee in the amount of Two Hundred Thousand Dollars ($200,000.00); and 

        WHEREAS, Pledgee is willing to accept the Note from Pledgor, but only upon the condition, among others, that Pledgor shall have executed
and delivered to Pledgee this Pledge Agreement and the Pledged Collateral (as defined below); 

        NOW, THEREFORE, in consideration of the foregoing recitals and for other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, and intending to be legally bound, Pledgor hereby agrees as follows: 

        1.     As security for the full, prompt and complete payment and performance when due (whether by stated maturity, by
acceleration or otherwise) of all indebtedness of Pledgor to Pledgee created under the Note, together with, without limitation, the prompt payment of all expenses, including, without limitation,
reasonable attorneys' fees and legal expenses, incidental to the collection of the foregoing and the enforcement or protection of Pledgee's lien in and to the collateral pledged hereunder (all such
indebtedness being the "Liabilities"), Pledgor hereby pledges to Pledgee, and grants to Pledgee, a first priority security interest in all of the
following (collectively, the "Pledged Collateral"): 

        (a)   all shares of Common Stock of the Pledgee exercisable upon that certain stock option granted to Pledgor by Pledgee (the
"Pledged Stock") pursuant to that certain Stock Option Agreement executed by and between Pledgor and Pledgee dated August 1, 2002, and all common
stock, dividends, cash, instruments and other property or proceeds from time to time received, receivable or otherwise distributed upon the exercise of any or all of the Pledged Stock; 

        (b)   all voting trust certificates held by Pledgor evidencing the right to vote any shares of common stock subject to any
voting trust upon the exercise of the Pledged Options; and 

        (c)   all additional shares of Common Stock of the Pledgee and voting trust certificates from time to time acquired by Pledgor
from Pledgee in any manner (which additional shares shall be deemed to be part of the Pledged Collateral), and the certificates representing such additional shares, and all dividends, cash,
instruments and other property or proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such shares. 

        The
term "indebtedness" is used herein in its most comprehensive sense and includes any and all advances, debts, obligations and liabilities heretofore, now or hereafter made, incurred
or created, whether voluntary, or involuntary, and whether due or not due, absolute or contingent, liquidated or unliquidated, determined or undetermined, and whether recovery upon such indebtedness
may be or hereafter becomes unenforceable. 

        2.     Pledgor hereby represents and warrants to Pledgee as follows: 

        (a)   Pledgor is, and at all times during which this Pledge Agreement is in effect shall be, the sole holder of record and the
sole beneficial owner of the Pledged Collateral, free and 

1

 

clear
of any lien thereon or affecting title thereto, except for the lien created by this Pledge Agreement. 

        (b)   None of the Pledged Collateral have been transferred in violation of securities registration, securities disclosure or
similar laws of any jurisdiction to which such transfer may be subject. 

        (c)   No consent, approval, authorization or other order of any person and no consent or authorization of any governmental
authority or regulatory body is required to be made or obtained by Pledgor either (i) for the pledge by Pledgor of the Pledged Collateral pursuant to this Pledge Agreement or for the execution,
delivery, or performance of this Pledge Agreement by Pledgor; or (ii) for the exercise by
Pledgee of the voting or other rights provided for in this Pledge Agreement or the remedies with respect to the Pledged Collateral pursuant to this Pledge Agreement, except as may be required in
connection with such disposition by laws affecting the offering and sale of securities generally. 

        (d)   The pledge, grant of a security interest in, and delivery of the Pledged Collateral pursuant to this Pledge Agreement,
will create a valid first priority lien on and in the collateral pledged by Pledgor, and the proceeds thereof, securing the payment of the Liabilities. 

        (e)   This Pledge Agreement has been duly executed and delivered by Pledgor and constitutes a legal, valid, and binding
obligation of Pledgor enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, or other similar laws affecting the rights of creditors generally or
by the application of general equity principles. 

        Pledgor
covenants, warrants, and represents to Pledgee that all representations and warranties contained in this Pledge Agreement shall be true at the time of Pledgor's execution of this
Pledge Agreement, and shall continue to be true until the Liabilities have been paid or otherwise satisfied in full. 

        3.     At any time, without notice, and at the expense of Pledgor, Pledgee in its name or in the name of its nominee or of
Pledgor may, but shall not be obligated to: (a) collect by legal proceedings or otherwise all dividends (except cash dividends other than liquidating dividends), interest, principal payments
and other sums now or hereafter payable upon or on account of said Pledged Collateral; (b) enter into any extension, reorganization, deposit, merger or consolidation agreement, or any agreement
in any way relating to or affecting the Pledged Collateral, and in connection therewith may deposit or surrender control of such Pledged Collateral thereunder, accept other property in exchange for
such Pledged Collateral and do and perform such acts and things as it may deem proper, and any money or property received in exchange for such Pledged Collateral shall be applied to the indebtedness
or thereafter held by it pursuant to the provisions hereof; (c) insure, process and preserve the Pledged Collateral; (d) cause the Pledged Collateral to be transferred to its name or to
the name of its nominee; and (e) exercise as to such Pledged Collateral all the rights, powers and remedies of an owner, except that so long as no Event of Default (as defined in the Note)
exists under the Note, Pledgor shall retain all voting rights as to the shares of common stock obtained by Pledgor upon the exercise of the Pledged Options. 

        4.     Pledgor agrees to pay prior to delinquency all taxes, charges, liens and assessments against the Pledged Collateral, and
upon the failure of Pledgor to do so, Pledgee at its option may pay any of them and shall be the sole judge of the legality or validity thereof and the amount necessary to discharge the same. 

2

 

        5.     Pledgor agrees that Pledgor: 

        (a)   will not (i) sell, transfer or otherwise dispose of, or grant any option or warrant with respect to, any of the
Pledged Collateral (or any part thereof or interest therein) except with the prior written consent of Pledgee, or (ii) create or permit to exist any lien or encumbrance upon or with respect to
any of the Pledged Collateral. If any Pledged Collateral, or any part thereof, is sold, transferred or otherwise disposed of in violation of this Section 5, the security interest of Pledgee
shall continue in the Pledged Collateral notwithstanding such sale, transfer or other disposition, and the Pledgor will deliver any proceeds thereof to the Pledgee to be held as Pledged Collateral
hereunder; 

        (b)   shall, at Pledgor's own expense, promptly execute, acknowledge, and deliver all such instruments and take all such
actions as Pledgee from time to time may reasonably request in order to ensure to Pledgee the benefits of the lien in and to the Pledged Collateral intended to be created by this Pledge Agreement,
including, without limitation, delivering any share certificates representing the common stock obtained by Pledgor upon the exercise of any Pledged Options; and 

        (c)   shall maintain, preserve and defend the title to the Pledged Collateral and the lien of Pledgee thereon against the claim
of any other person. 

        6.     All advances, charges, costs and expenses, including reasonable attorneys' fees, incurred or paid by Pledgee in exercising
any right, power or remedy conferred by this agreement, or in the enforcement thereof, shall become a part of the indebtedness secured hereunder and shall be paid to Pledgee by Pledgor immediately and
without demand. 

        7.     Upon the occurrence and during the continuance of an Event of Default (as defined in the Note), Pledgee may then, or at
any time thereafter, at its election, apply, set off, collect or sell in one or more sales, or take such steps as may be necessary to liquidate and reduce to cash in the hands of Pledgee in whole or
in part, with or without any previous demands or demand of performance or notice or advertisement, the whole or any part of the Pledged Collateral in such order as Pledgee may elect, and any such sale
may be made either at public or private sale at its place of business or elsewhere, or at any broker's board or securities exchange, either for cash or upon credit or for future delivery; provided,
however, that if such disposition is at private sale, then the purchase price of the Pledged Collateral shall be equal to the public market price then in effect, or, if at the time of sale no public
market for the Pledged Collateral exists, then, in recognition of the fact that the sale of the Pledged Collateral would have to be registered under the Securities Act of 1933 and that the expenses of
such registration are commercially unreasonable for the type and amount of collateral pledged hereunder, Pledgee and Pledgor hereby agree that such private sale shall be at a purchase price mutually
agreed to by Pledgee and Pledgor or, if the parties cannot agree upon a purchase price, then at a purchase price established by the Board of Directors of the Pledgee in the exercise of its reasonable
discretion. Pledgee may be the purchaser of any or all Pledged Collateral so sold and hold the same thereafter in its own right free from any claim of Pledgor or right of redemption. Demands of
performance, notices of sale, advertisements and presence of property at sale are hereby waived, and Pledgee is hereby
authorized to sell hereunder any evidence of debt pledged to it. Any sale hereunder may be conducted by any officer or agent of Pledgee. 

        8.     The proceeds of the sale of any of the Pledged Collateral and all sums received or collected by Pledgee from or on account
of such Pledged Collateral shall be applied by Pledgee to the payment of expenses incurred or paid by Pledgee in connection with any sale, transfer or delivery of the Pledged Collateral, to the
payment of any other costs, charges, attorneys' fees or expenses mentioned herein, and to the payment of the indebtedness or any part hereof, all in such order and manner as Pledgee in its discretion
may determine, with Pledgor remaining liable for 

3

 

any
deficiency remaining unpaid after such application. Only after so paying over such net proceeds need Pledgee account for the surplus, if any, to Pledgor. 

        9.     Upon the transfer of all or any part of the indebtedness Pledgee may transfer all or any part of the Pledged Collateral
and shall be fully discharged thereafter from all liability and responsibility with respect to such Pledged Collateral so transferred, and the transferee shall be vested with all the rights and powers
of Pledgee hereunder with respect to such Pledged Collateral so transferred; but with respect to any Pledged Collateral not so transferred Pledgee shall retain all rights and powers hereby given. 

        10.   Until all indebtedness shall have been paid in full the power of sale and all other rights, powers and remedies granted
to Pledgee hereunder shall continue to exist and may be exercised by Pledgee at any time and from time to time irrespective of the fact that the indebtedness or any part thereof may have become barred
by any statute of limitations, or that the personal liability of Pledgor may have ceased. 

        11.   Pledgee may at any time deliver the Pledged Collateral or any part thereof to Pledgor and the receipt thereof by Pledgor
shall be a complete and full acquittance for the Pledged Collateral so delivered, and Pledgee shall thereafter be discharged from any liability or responsibility therefor. 

        12.   The rights, powers and remedies given to Pledgee by this Pledge Agreement shall be in addition to all rights, powers and
remedies given to Pledgee by virtue of any statute or rule of law. Any forbearance, failure or delay by Pledgee in exercising any right, power or remedy hereunder shall not be deemed to be a waiver of
such right, power or remedy, and any single or partial exercise of any right, power or remedy hereunder shall not preclude the further exercise thereof: and every right, power and remedy of Pledgee
shall continue in full force and effect until such right, power or remedy is specifically waived by an instrument in writing executed by Pledgee. 

        13.   If any provision of this Pledge Agreement is held to be unenforceable for any reason, it shall be adjusted, if possible,
rather than voided in order to achieve the intent of the parties to the extent possible. In any event, all other provisions of this Pledge Agreement shall be deemed valid and enforceable to the full
extent possible. 

        14.   This Pledge Agreement shall be governed by, and construed in accordance with, the laws of the State of California as
applied to contracts made and performed entirely within the State of California by residents of such State.
