                                TRUST AGREEMENT


    THIS AGREEMENT, made as of this 31st day of January, 1995, by and between
Briggs & Stratton Corporation (Company) and Johnson Heritage Trust Company
(Trustee);

    WHEREAS, this trust was created November 1, 1989, and thereafter the
Internal Revenue Service, in July, 1992, published Revenue Procedure 92-64,
containing a model form of "Rabbi Trust";

    WHEREAS, the parties desire and intend to restate and continue this trust
in the form of such IRS model, and change the Trustee, retaining provisions of
the prior trust to the extent permitted by such Revenue Procedure, all as set
forth below;

    WHEREAS, the purpose of this trust is to: (a) hold assets deposited by the
Company as a reserve for the discharge of the Company's obligations to
individuals (the "participants") and their beneficiaries as applicable entitled
to receive payments: (l) under Supplemental Benefit Agreements or Employment
Agreements made with the Company, copies of which are or in the future will be
attached hereto as Exhibits to this Agreement for information purposes or (2)
under any other plan of deferred compensation or retirement payments that the
Company designates in writing to the Trustee (or attaches hereto by reference
in an index, or by complete document) for such purpose hereunder, including
those established by resolution of the directors of Company, all of such
agreements and plans referred to in (l) and (2) hereof being termed "Plans"
herein, and (b) disburse and distribute those assets as provided hereunder and
in the Plans, provided however that no additional Plans shall be added
following the occurrence of a "Change of Control Event" as defined in Section
13(d). Prior to a change in control event, the Company may, from time to time,
change, add, or delete Plans by written notice to the Trustee to reflect
changes in personnel or Plans;

    WHEREAS, Company wishes to establish a trust (hereinafter called "Trust")
and to contribute to the Trust assets that shall be held therein, subject to
the claims of Company's creditors in the event of Company's Insolvency, as
herein defined, until paid to Plan participants and their beneficiaries in such
manner and at such times as specified in the Plans;

    WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of the Plans
as an unfunded plan maintained for the purpose of providing deferred
compensation for a select group of management or highly compensated employees
for purposes of Title I of the Employee Retirement Income Security Act of 1974;

    WHEREAS, it is the intention of Company to make contributions to the Trust
to provide itself with a source of funds to assist it in the meeting of its
liabilities under the Plans;

    NOW, THEREFORE, the parties do hereby establish the Trust and agree that
the Trust shall be comprised, held and disposed of as follows:


                                      1

    Section 1.   ESTABLISHMENT OF TRUST.

    (a) Company hereby deposits with Trustee in trust all assets transferred
from the prior Trustee, which shall become the principal of the Trust to be
held, administered and disposed of by Trustee as provided in this Trust
Agreement.

    (b) The Trust hereby established is revocable by Company; it shall become
irrevocable upon a change of control, as defined herein.

    (c) The Trust is intended to be a grantor trust, of which Company is the
grantor, within the meaning of subpart E, part I, subchapter J, chapter 1,
subtitle A of the Internal Revenue Code of 1986 as amended and shall be
construed accordingly.

    (d) The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of Company and shall be used exclusively
for the uses and purposes of Plan participants and general creditors as here
and set forth. Plan participants and their beneficiaries shall have no
preferred claim on, or any beneficial ownership interest in, any assets of the
Trust. Any rights created under the Plans and this Trust Agreement shall be
mere unsecured contractual rights of Plan participants and their beneficiaries
against Company. Any assets held by the Trust will be subject to the claims of
Company's general creditors under federal and state law in the event of
Insolvency, as defined in Section 3(a) herein.

    (e) Upon a change of control, Company shall, as soon as possible, but in no
event longer than 5 days following the change of control, as defined herein,
make an irrevocable contribution to the Trust in an amount that is sufficient
to pay each Plan participant or beneficiary the benefits to which Plan
participants or their beneficiaries would be entitled pursuant to the terms of
the Plans as of the date on which the change of control occurred.

    Section 2.   PAYMENTS TO PLAN PARTICIPANTS AND THEIR BENEFICIARIES.

    (a) Company shall deliver to Trustee a schedule (the "Payment Schedule")
that indicates the amounts payable in respect of each Plan participant (and his
or her beneficiaries), that provides a formula or other instruction acceptable
to Trustee for determining the amounts so payable, the form in which such
amount is to be paid (as provided for or available under the Plans), and the
time of commencement for payment of such amounts. Except as otherwise provided
herein, Trustee shall make payments to the Plan participants and their
beneficiaries in accordance with such Payment Schedule. The Trustee shall make
provision for the reporting and withholding of any federal, state or local
taxes that may be required to be withheld with respect to the payment of
benefits pursuant to the terms of the Plans and shall pay amounts withheld to
the appropriate taxing authorities or determine that such amounts have been
reported, withheld and paid by Company.

    (b) The entitlement of a Plan participant or his or her beneficiaries to
benefits under the Plans shall be determined by Company or such party as it
shall designate under the Plans, and any claim for such benefits shall be
considered and reviewed under the procedures set out in the Plans.

    (c) Company may make payment of benefits directly to Plan participants or
their beneficiaries as they become due under the terms of the Plans. Company
shall notify Trustee of its decision to make payments of benefits directly
prior to the time amounts are payable to participants or their beneficiaries.
In addition, if the principal of the Trust, and any earnings thereon, are not
sufficient to make payments of benefits in accordance with the terms of the
Plans, Company shall make the balance of each such payment as it falls due.
Trustee shall notify Company where principal and earnings are not sufficient.

    Section 3.   TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO TRUST BENEFICIARY
WHEN COMPANY IS INSOLVENT.

    (a) Trustee shall cease payment of benefits to Plan participants and their
beneficiaries if the Company is Insolvent. Company shall be considered
"Insolvent" for purposes of this Trust Plan if (i) Company is unable to pay its
debts as they become due, or (ii) Company is subject to a pending proceeding as
a debtor under the United States Bankruptcy Code.

    (b) At all times during the continuance of this Trust, as provided in
Section l(d) hereof, the principal and income of the Trust shall be subject to
claims of general creditors of Company under federal and state law as set forth
below.

             (l) The Board of Directors and the Chief Executive Officer of
    Company shall have the duty to inform Trustee in writing of Company's
    Insolvency. If a person claiming to be a creditor of Company alleges in
    writing to Trustee that Company has become Insolvent, Trustee shall
    determine whether Company is Insolvent and, pending such determination,
    Trustee shall discontinue payment of benefits to Plan participants or their
    beneficiaries.

             (2) Unless Trustee has actual knowledge of Company's Insolvency,
    or has received notice from Company or a person claiming to be a creditor
    alleging that Company is Insolvent, Trustee shall have no duty to inquire
    whether Company is Insolvent. Trustee may in all events rely on such
    evidence concerning Company's solvency as may be furnished to Trustee and
    that provides Trustee with a reasonable basis for making a determination
    concerning Company's solvency.

             (3) If at any time Trustee has determined that Company is
    Insolvent, Trustee shall discontinue payments to Plan participants or their
    beneficiaries and shall hold the assets of the Trust for the benefit of
    Company's general creditors. Nothing in this Trust Plan shall in any way
    diminish any rights of Plan participants or their beneficiaries to pursue
    their rights as general creditors of Company with respect to benefits due
    under the Plans or otherwise.

             (4) Trustee shall resume the payment of benefits to Plan
    participants or their beneficiaries in accordance with Section 2 of this
    Trust Plan only after Trustee has determined that Company is not Insolvent
    (or is no longer Insolvent).

    (c) Provided that there are sufficient assets, if Trustee discontinues the
payment of benefits from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
participants or their beneficiaries under the terms of the Plans for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
participants or their beneficiaries by Company in lieu of the payments provided
for hereunder during any such period of discontinuance.

    Section 4.   PAYMENTS TO COMPANY.

    Except as provided in Section 3 hereof, after the Trust has become
irrevocable, Company shall have no right or power to direct Trustee to return
to Company or to divert to others any of the Trust assets before all payment of
benefits have been made to Plan participants and their beneficiaries pursuant
to the terms of the Plans.

    (b) To carry out the purposes of the Trust and subject to any limitations
herein expressed, the Trustee is vested with the following powers until final
distribution, in addition to any now or hereafter conferred by law affecting
the trust or estate created hereunder. In exercising such powers, the Trustee
shall act in a manner reasonable and equitable in view of the interests of the

    in the administration of the Trust or because of the holding or ownership
    of any Trust assets, for which advances, with interest, the Trustee has a
    lien on the Trust assets as against the Beneficiaries and in the event such
    assets are not sufficient a lien against the assets of the Company,
    provided however that until Funding of the Trust as provided in Section
    l(e), it is the intention of the Company and the Trustee that statements
    for the costs of administration of the trust shall be submitted to and paid
    by the Company in the normal course of business.

             (5) Pay, Contest or Settle Claims. To pay, contest, or settle any
    claim by or against the Trust by compromise, arbitration or otherwise; to
    release, in whole or in part, any claim belonging to the Trust to the
    extent that the claim is uncollectible. Notwithstanding the foregoing, the

    Company if it is compelled to do so by a final order of a court of
    competent jurisdiction.

             (6) Litigate. To prosecute or defend actions, claims or
    proceedings to insure funding of the Trust and for the protection of Trust
    assets and the Trustee in the performance of its duties.

    interest of the Trust, without liability for interest thereon. (ii) To
    invest Trust assets in investment fixed income securities having a Standard

accountability. The Company will be deemed to have given its written approval
if it does not object in writing to the Trustee within 120 days after the date

    (a) The Trustee hereby agrees and consents to act as Trustee hereunder. The
Company agrees to indemnify the Trustee and hold it harmless from and against
all claims, liabilities, legal fees and expenses that may be asserted against
it, individually or collectively, otherwise than on account of the Trustee's
own gross negligence or willful misconduct by reason of the Trustee's taking or
refraining from taking any action in connection with the Trust, whether or not
the Trustee is party to a legal proceeding or otherwise.

    (b) If the Trustee undertakes or defends any litigation arising in
connection with this trust, Company agrees to indemnify Trustee against
Trustee's costs, expenses and liabilities (including, without limitation,

and their beneficiaries are no longer entitled to benefits pursuant to the
terms of the Plans unless sooner revoked in accordance with Section l(b)
hereof. Upon termination of the Trust any assets remaining in the Trust shall
be returned to Company.

    (c) Upon written approval of participants or beneficiaries entitled to
payment of benefits pursuant to the terms of the Plans, Company may terminate
this Trust prior to the time all benefit payments under the Plans have been
