(i)
    
    By Share Withholding.The Grantee authorizes Connetics
to, upon the exercise of Connetics sole discretion, withhold from
those Shares issuable to the Grantee the whole number of Shares
sufficient to satisfy the minimum applicable Tax Withholding
Obligation. The Grantee acknowledges that the withheld Shares may not
be sufficient to satisfy the Grantees minimum Tax Withholding
Obligation. Accordingly, the Grantee agrees to pay to Connetics or any
Parent or Subsidiary of Connetics as soon as practicable, including
through additional payroll withholding, any amount of the Tax
Withholding Obligation that is not satisfied by the withholding of
Shares described above.(ii)
    
    By Sale of Shares. Unless the Grantee determines to
satisfy the Tax Withholding Obligation by some other means in
accordance with clause (iii) below, the Grantees acceptance of this
Award constitutes the Grantees instruction and authorization to
Connetics or Broker to sell on the Grantees behalf a whole number of
Shares from those Shares issuable to the Grantee as Connetics
determines to be appropriate to generate cash proceeds sufficient to
satisfy the minimum applicable Tax Withholding Obligation. Such Shares
will be sold on the day such Tax Withholding Obligation arises (e.g.,a
vesting date) or as soon after that day as practicable. The Grantee
agrees to execute and deliver any documents, instruments, or
certificates that Connetics or the Broker may require in connection
with the sale of Shares pursuant to this Section. The Grantee will be
responsible for all Brokers fees and other costs of sale, and the
Grantee agrees to indemnify and hold Connetics harmless from any
losses, costs, damages, or expenses relating to any such sale. To the
extent the proceeds of such sale exceed the Grantees minimum Tax
Withholding Obligation, the Company agrees to pay the excess amount in
cash to the Grantee. The Grantee acknowledges that Connetics or its
designee is under no obligation to arrange to sell any Shares at any
particular price, and that the proceeds of any such sale may not be
sufficient to satisfy the Grantees minimum Tax Withholding Obligation.
Accordingly, the Grantee agrees to pay to Connetics or its Parent or
Subsidiary as soon as practicable, including through additional payroll
withholding, any amount of the Tax Withholding Obligation that is not
satisfied by the sale of Shares described above.(iii)
    
    By Check, Wire Transfer or Other Means. At any time
not less than five business days (or such fewer number of business days
as the Administrator determines) before any Tax Withholding Obligation
arises (e.g.,a vesting date), the Grantee may elect to satisfy the
Grantees Tax Withholding Obligation by delivering to Connetics an
amount that Connetics determines is sufficient to satisfy the Tax
