     below, the Corporation's Death Benefit) shall be paid or
     repaid to the Corporation in the following manner:
     (a)  Notwithstanding any provision of this Agreement or the
          Policy that may be construed to the contrary, if the
          Benefit Measurement Date occurs due to the death of the
          Decedent, (i) the Corporation shall be entitled to that
          portion of the Policy's death proceeds that equals the
          sum of the Collateral Interest and the Corporation's

          all steps necessary to collect the death proceeds of the
          Policy by submitting the proper claims forms to the
          Insurer.  The Corporation shall notify the Insurer of
          the amount of the Owner's Death Benefit (except when the
          Policy's proceeds are limited because of the Decedent's
          death by suicide) and the Corporation's Collateral
          Interest in the Policy at the time of such death.  Such
          amounts shall be paid, respectively, by the Insurer to
          the Owner or to the Designated Beneficiary, as the case
          may be, and the Corporation.

A.   The Corporation desires to help the Owner provide life
     insurance for the benefit and protection of the Participant's
     family or beneficiary by providing funds from time to time to pay
     the premiums due on the Policy as more specifically provided in
     the ALZA Corporation Executive Estate Protection Plan Agreement
     entered into between the Participant, the Owner and the
     Corporation as of the date hereof (the "Agreement");
B.   In consideration of the Corporation agreeing to provide such
     funds in accordance with the terms and conditions of the
     Agreement, the Owner agrees to grant to the Corporation, as a
     security interest in the Policy, a collateral security interest
     for the payment of the Corporation's Collateral Interest (as
     defined below); and
C.   The Corporation has established a trust ("Trust") dated
     ________________, 1998, by and between the Corporation and
     ______________________________ ("Trustee") to provide a source of
     funds to cover its obligations under the Agreement.

                             AGREEMENT
NOW, THEREFORE, in consideration of the foregoing, and the mutual
agreements and covenants set forth below, the parties to this
Assignment agree as follows:
1.   Assignment.  The Owner hereby assigns, transfers and sets
     over to the Corporation, and its permitted successors, those
     certain rights and interests described in the Agreement that
     are to be assigned to the Corporation in accordance with the
     Agreement.  Furthermore, this Assignment is made, and the
     Policy is to be held as collateral security for, any and all
     liabilities of the Owner to the Corporation, either now
     existing, or that may hereafter arise, pursuant to the terms
     of the Agreement.
2.   Signatures.  To facilitate the operation of this Assignment,
     the parties agree that the Insurer is hereby notified that
     the following signatures are sufficient, without the
     signature or consent of the other party, to exercise the
     following rights under the Policy while the Assignment is in
     effect:
     (a)  The Owner may sign a request to change the beneficiary
          under the Policy without the signature or consent of the
          Corporation; and
     (b)  The exercise of any other right under the Policy not
          specifically set forth above shall be exercised with the
          signature of both the Corporation and the Owner.
3.   Policy Proceeds.  Any amount payable from the Policy during
     the Participant's life or at his or her death shall first be paid
     to the Corporation to the extent of its Collateral Interest (as
     defined in the Agreement).  Any balance will be paid to the Owner
     during the Participant's lifetime or to the Designated Beneficiary
     (as defined in the Agreement) upon or after the Participant's
     death.  A settlement option may be elected by the recipient of the
     proceeds.  For purposes of this Section, the amount of the
     Collateral Interest shall be determined for purposes of the
     Insurer by an affidavit delivered to the Insurer and signed by the
     Corporation.
4.   Endorsement.  The Trustee shall hold the Policy while this
     Assignment is operative and, upon request, forward the Policy to
     the Insurer, without unreasonable delay, for endorsement of any
     designation or change of beneficiary, any election of optional
     mode of settlement, or the exercise of any other right reserved by
     the Owner in this Assignment.
5.   Insurer.  The Insurer is hereby authorized to recognize the
     Corporation's claims to rights hereunder without investigating the
     reason for any action taken by the Corporation, the validity or
     amount of any of the liabilities of the Owner to the Corporation
     under the Agreement, the existence of any default therein, the
     giving of any notice required herein, or the application to be
     made by the Corporation of any amounts to be paid to the
     Corporation or the transfer of the Policy to the Corporation.  The
     Insurer shall not be responsible for the sufficiency or validity
     of this Assignment and is not a party to the Agreement (or any
     other similar split-dollar agreement) between the Corporation and
     the Owner or the Participant.
6.   Reassignment.  Upon the full payment of the Corporation's
     Collateral Interest in accordance with the terms and conditions of
     this Assignment and the Agreement, the Corporation shall reassign
     to the Owner, if the Owner retains the Policy in accordance with
     the Agreement, the Policy and all specific rights included in this
     Assignment.
7.   Amendment of Assignment; Termination.  This Assignment shall
     not be modified, amended or terminated, except by a writing signed
     by all the parties hereto.
8.   Assignment .  This Assignment may be collaterally assigned
     with the Agreement by the Owner pursuant to the Owner's rights
     under Section 5 of the Agreement.
9.   Binding Agreement; Assigns.  This Assignment shall be binding
     upon the heirs, administrators, executors and permitted successors
     and assigns of each party to this Assignment.
10.  State Law.  This Assignment shall be subject to and be
     construed under the internal laws of the State of California,
     without regard to its conflicts of law principles.
11.  Validity.  In case any provision of this Assignment shall be
     illegal or invalid for any reason, said illegality or invalidity
     shall not affect the remaining parts of this Assignment,
     but this Assignment shall be construed and enforced as if
     such illegal or invalid provision had never been inserted in
     this Assignment.
     IN WITNESS WHEREOF, the Owner and the Corporation have signed
this Assignment as of the date first written above.
