        This agreement is made by and between Genelabs Technologies, Inc.
("Genelabs") and Irene A. Chow, Ph.D. ("Employee").

        I. Option Acceleration Benefits. Immediately upon the effective date of
a Change in Control (as defined below), all unvested shares of any and all stock
options granted by Genelabs to Employee shall vest in full.

        II. Severance Benefits. In the event that there is an Involuntary
Termination (as defined below) of Employee's employment with Genelabs or with
any successor thereto (collectively the "Company") within eighteen (18) months
immediately following the effective date of a Change in Control, Employee shall
be entitled to receive the following:

                A. Salary Continuation. For a total of twenty-four (24) full
        calendar months after such Involuntary Termination, continued payment of
        base salary at the rate in effect for Employee immediately prior to the
        time of the event resulting in Employee's Involuntary Termination, or if
        greater, immediately prior to the Involuntary Termination, paid at
        periodic intervals in accordance with the Company's payroll practices
        for salaried employees and subject to all applicable tax withholding
        requirements.

                B. Bonus Payment. Not later than forty-five (45) days after the
        Employee's Involuntary Termination, a lump sum payment of 150% of the
        Employee's target bonus potential pursuant to any annual bonus or
        incentive plan or program for the calendar year in which the Involuntary
        Termination takes place, including 150% of any other annual incentive
        bonus compensation for such calendar year (in each case, if applicable,
        calculated as if Employee met 100% of Employee's objectives, and the
        Company met 100% of the Company's objectives), and the amount of any
        vested but unpaid long-term incentive bonus including any amount that
        would have vested during that calendar year and/or would have been paid
        out in the following calendar year, subject to all applicable tax
        withholding requirements.

                C. Health Care Coverage. For a total of eighteen (18) full
        calendar months immediately following the Employee's Involuntary
        Termination, continued coverage under the Company's medical and dental
        benefit plans, without charge, for Employee and/or Employee's eligible
        dependents upon their respective election to receive such continued
        benefit plan coverages pursuant to the federal law known as COBRA. Any
        other coverages to which Employee and/or Employee's dependents may elect
        during or after the twelve (12) month period of Company-paid coverage,
        pursuant to COBRA, shall be at the sole cost and expense of Employee
        and/or Employee's eligible dependents.

        III.    Internal Revenue Code Section 280G Treatment.

                A. Notwithstanding any other provisions of this agreement, in
        the event that any payment or benefit received or to be received by
        Employee in connection with a Change in Control or the termination of
        Employee's employment (whether pursuant to

<PAGE>

        the terms of this agreement or any other plan, arrangement or agreement
        with the Company, any person whose actions result in a Change in Control
        or any person affiliated with the Company or such person) (all such
        payments and benefits, including the payments and benefits provided
        under this agreement (the "Severance Payments"), being hereinafter
        called "Total Payments") would be subject (in whole or part), to the
        excise tax (the "Excise Tax") imposed under section 4999 of the Internal
        Revenue Code of 1986, as amended (the "Code"), then, after taking into
        account any reduction in the Total Payments provided by reason of
        section 280G of the Code in such other plan, arrangement or agreement,
        the cash Severance Payments shall first be reduced, and the noncash
        Severance Payments shall thereafter be reduced, to the extent necessary
        so that no portion of the Total Payments is subject to the Excise Tax
        but only if (i) the net amount of such Total Payments, as so reduced
        (and after subtracting the net amount of federal, state and local income
        taxes on such reduced Total Payments) is greater than or equal to (ii)
        the net amount of such Total Payments without such reduction (but after
        subtracting the net amount of federal, state and local income taxes on
        such Total Payments and the amount of Excise Tax to which Employee would
        be subject in respect of such unreduced Total Payments); provided,
        however, that Employee may elect to have the noncash Severance Payments
        reduced (or eliminated) prior to any reduction of the cash Severance
        Payments.

               B. For purposes of determining whether and the extent to which
        the Total Payments will be subject to the Excise Tax, (i) no portion of
        the Total Payments the receipt or enjoyment of which Employee shall have
        waived at such time and in such manner as not to constitute a "payment"
        within the meaning of section 280G(b) of the Code shall be taken into
        account, (ii) no portion of the Total Payments shall be taken into
        account which, in the opinion of tax counsel ("Tax Counsel") reasonably
        acceptable to Employee and selected by the accounting firm (the
        "Auditor") which was, immediately prior to the Change in Control, the
        Company's independent auditor, does not constitute a "parachute payment"
        within the meaning of section 280G(b)(2) of the Code (including by
        reason of section 280G(b)(4)(A) of the Code) and, in calculating the
        Excise Tax, no portion of such Total Payments shall be taken into
        account which, in the opinion of Tax Counsel, constitutes reasonable
        compensation for services actually rendered, within the meaning of
        section 280G(b)(4)(B) of the Code, in excess of the "base amount" within
        the meaning of section 280G(b)(3) of the Code, allocable to such
        reasonable compensation, and (iii) the value of any non-cash benefit or
        any deferred payment or benefit included in the Total Payments shall be
        determined by the Auditor in accordance with the principles of sections
        280G(d)(3) and (4) of the Code.

               C. At the time that payments are made under this agreement, the
        Company shall provide Employee with a written statement setting forth
        the manner in which such payments were calculated and the basis for such
        calculations including, without limitation, any opinions or other advice
        the Company has received from Tax Counsel, the Auditor or other advisors
        or consultants (and any such opinions or advice which are in writing
        shall be attached to the statement). If Employee objects to the
        Company's calculations, the Company shall pay to Employee such portion
        of the Severance Payments (up to 100% thereof) as Employee determines is
        necessary to result in the proper application of subsection A of this
        Section III.

        the terms of this agreement or any other plan, arrangement or agreement
        with the Company, any person whose actions result in a Change in Control

        subtracting the net amount of federal, state and local income taxes on
        such Total Payments and the amount of Excise Tax to which Employee would
        be subject in respect of such unreduced Total Payments); provided,
        however, that Employee may elect to have the noncash Severance Payments

        Company's independent auditor, does not constitute a "parachute payment"
        within the meaning of section 280G(b)(2) of the Code (including by
        reason of section 280G(b)(4)(A) of the Code) and, in calculating the
        Excise Tax, no portion of such Total Payments shall be taken into

        compensation for services actually rendered, within the meaning of
        section 280G(b)(4)(B) of the Code, in excess of the "base amount" within
        the meaning of section 280G(b)(3) of the Code, allocable to such
        reasonable compensation, and (iii) the value of any non-cash benefit or
        any deferred payment or benefit included in the Total Payments shall be
        determined by the Auditor in accordance with the principles of sections

        the Company has received from Tax Counsel, the Auditor or other advisors
        or consultants (and any such opinions or advice which are in writing
        shall be attached to the statement). If Employee objects to the
        Company's calculations, the Company shall pay to Employee such portion
        of the Severance Payments (up to 100% thereof) as Employee determines is
        necessary to result in the proper application of subsection A of this
        Section III.
