                     SPLIT DOLLAR LIFE INSURANCE AGREEMENT
                     -------------------------------------

     This amendment to that certain SPLIT DOLLAR LIFE INSURANCE AGREEMENT
("Agreement") dated April 6, 1992, by and between CROWLEY MARITIME CORPORATION,
a Delaware corporation (the "Corporation") and THOMAS B. CROWLEY, JR., (its
"Employee") is made on May 1, 1995.

     First: Paragraph 1 of this Agreement is amended in its entirety to read as
follows:

     "1. Ownership of the Policy.
         -----------------------

     (a) The Employee is the sole owner of the Policy, and may exercise all
incidents of ownership with respect thereto without the Corporation's consent,
subject only to the limited rights given the Corporation under the terms of the
limited collateral assignment provided for herein.

     (b) The Employee shall execute and deliver a limited collateral assignment
to the Corporation as security for repayment of the amount due to the
Corporation under this Agreement. However, the Corporation shall neither have
nor exercise any rights as collateral assignee of the Policy that could in any
way defeat or impair the Employee's right to receive the cash surrender value or
the death proceeds of the Policy in excess of the amount due to the Corporation
hereunder. In no event shall the Corporation have the power to change the
beneficiary, to surrender the Policy, to assign or revoke an assignment, to
pledge the Policy for a loan, or to obtain from


<PAGE>
the insurer a loan against the surrender value of the Policy. All provisions of
this Agreement and of such collateral assignment shall be construed so as to
carry out such intention. A form of the Limited Collateral Assignment is
attached hereto as Exhibit A."

     Second: Except as modified by this Amendment, all provisions of the
Agreement shall remain in effect.

     IN WITNESS WHEREOF, the parties hereto have signed this Amendment to Split
Dollar Life Insurance Agreement as of the day and year first above written.
