SPLIT DOLLAR INSURANCE AGREEMENT


    THIS SPLIT DOLLAR INSURANCE AGREEMENT (the "Agreement") is entered into
effective as of the 29th day of December, 1995, by and between Best Lock
Corporation, a Delaware corporation (hereinafter referred to as "Best Lock"),
and Arlen Helterbrand, not individually, but solely as Trustee of the Russell C.
Best Irrevocable Trust under agreement dated October 11, 1995 (hereinafter
referred to as the "Trustee").

                                     WITNESSETH:

    WHEREAS, Best Lock recognizes that Russell C. Best, the Chief Executive
Officer of Best Lock, has contributed substantially to the success of Best Lock
over the last several years: and

    WHEREAS, Best Lock desires that Russell C. Best continue in the employ of
Best Lock; and

    WHEREAS, to further encourage Russell C. Best to remain in Best Lock's
employ, Best Lock desires to assist him in establishing and maintaining an
adequate life insurance program;

    WHEREAS, the Trustee is the owner of life insurance policy number 3811706
(hereinafter referred to as the "Policy") on the life of Russell C. Best
(hereinafter referred to as the "Insured") issued by The Guardian Life Insurance
Company (hereinafter referred to as the "Insurer"), in the face amount of Five
Million Dollars ($5,000,000.00); and

    WHEREAS, Best Lock and the Trustee have agreed upon a plan for the payment
of the premiums due or to become due on the Policy and for the mode of payment
of death benefits thereunder; and

    WHEREAS, for protection of their mutual interests, the parties hereto
desire and intend to set forth all their agreements relating thereto herein.

    NOW, THEREFORE, in consideration of the foregoing premises and other good
and valuable consideration, the sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

         1.   OWNERSHIP OF POLICY.  The Trustee shall be the sole and absolute
owner of the Policy, and may exercise all ownership rights granted to the owner
by the terms of the Policy.  Best Lock acknowledges that the Trustee is the
owner of the Policy, and Best Lock shall not have nor exercise any right in and
to the Policy except as otherwise provided herein.  It is the express intention
of the parties hereto that Best Lock shall not possess any right which would
result in Best Lock being deemed to be in possession of any incident of
ownership as described in Section 2042 of the Internal Revenue Code of 1986, as
amended (or any Treasury Regulations promulgated thereunder), or any similar
provision of subsequent law.

    2.   PAYMENT OF PREMIUMS AND INTEREST.  Premiums and interest on the Policy
shall be paid in accordance with and subject to the following terms and
conditions:


                                          1




         a)   Premiums and interest on the Policy shall be payable annually or
    more frequently, as the Trustee may elect, and in accordance with such
    bills therefor as shall be transmitted to the Trustee by the Insurer from
    time to time;

         b)   Each premium elected by the parties to be paid on the Policy (and
    any interest due on policy loans) shall be paid by the parties as follows:

              i)   an amount to be contributed by the Trustee (less any
         dividend applied toward the payment of the premium as elected by the
         Trustee) equal to the value of the economic benefit attributable to
         the life insurance protection provided on the life of the Insured
         under this Agreement, calculated by using the lower of (A) the P.S. 58
         rates or (B) the Insurer's term rates for one-year term life insurance
         available on the life of the Insured at all standard risks; and

              ii)  an amount to be contributed by the Trustee equal to the
         portion of the premium for the policy year attributable to the Duo-
         Guard rider forming part of the Policy; and

              iii) an amount to be contributed by Best Lock equaling the
         difference, if any, between the amounts required to be contributed by
         the Trustee during such policy year, as described in subparagraphs (i)
         and (ii) of this paragraph, and the total premium for such policy
         year; and

              iv)  an amount to be contributed by the Trustee equal to the
         interest on all policy loans made by the Trustee with respect to the
         Policy.

         c)   The amounts to be contributed by the parties as set forth above
    shall be paid by each party directly to the Insurer on or before the
    required due date; and each such payment shall identify the policy number
    of the Policy.  The Trustee shall be responsible for informing Best Lock as
    to all payment due dates with respect to the Policy.

         d)   Best Lock hereby covenant and agrees to make the contribution
    described in subparagraph 2(b)(iii) toward the premium for the first year
    of coverage of the Insured under the Policy.  Any additional contributions
    of Best Lock shall be made in the sole discretion of Best Lock.

    3.   INVESTMENTS BY BEST LOCK.  The amounts described in subparagraph
2(b)(iii) contributed by Best Lock shall constitute investments by Best Lock,
and the cumulative total of all such investments shall be referred to herein as
the "Cumulative Investment Amount."  The amount which is equal to the lesser of
(i) the Cumulative Investment Amount, or (ii) the then cash surrender value of
the Policy at the relevant time for determination, is herein referred to as Best
Lock's "Net Interest."  In consideration of Best Lock's payment of its share of
the premiums on the Policy pursuant to subparagraph 2(b)(iii) above, the Trustee
has, contemporaneously herewith, assigned the Policy to Best Lock as collateral
under the Assignment of Life Insurance Policy as Collateral (the "Assignment")
which gives Best Lock the limited power to enforce its right to recover Best
Lock's Net Interest or the Cumulative Investment Amount, as the case may be.
The interest of Best Lock in and to the Policy


                                          2



shall be specifically limited to the following rights in and to the cash
surrender value thereof or a portion of the death benefit thereof:

         a)   The right to be paid an amount equal to Best Lock's Net Interest
    in the Policy in the event the Policy is totally surrendered or canceled by
    the Trustee pursuant to paragraph 6 below; and

         b)   The right to be paid an amount equal to the Cumulative Investment
    Amount in the event of the death of the Insured; and

         c)   The right to be paid an amount equal to Best Lock's Net Interest
    or the Cumulative Investment Amount, as the case may be, in the event this
    Agreement is terminated pursuant to the provisions of paragraph 7 below.

         The foregoing Assignment shall be subject to all of the terms and
    conditions of the Policy and to all superior liens, if any, which the
    Trustee may have against the policy.

    4.   DESIGNATION OF BENEFICIARIES.  As long as this Agreement shall remain
in effect, Best Lock and the Trustee agree that the Trustee shall designate the
Trustee as the beneficiary of the Policy, and that upon the death of the Insured
while the Policy and this Agreement shall remain in force, the Trustee, upon
receipt of the proceeds of the Policy, shall divide such proceeds into two (2)
parts as follows:

         a)   One such part shall be payable in a lump sum to Best Lock and
    shall be an amount equal to the Cumulative Investment Amount determined as
    of the date of the death of the Insured; and

         b)   The other such part shall consist of the entire balance of the
    proceeds of the Policy and shall be retained by the Trustee.

         The Trustee may make any change of beneficiary or any election of an
optional mode of settlement desired with respect to that portion of the proceeds
of the Policy referred to in subparagraph (b) of this paragraph 4.

    5.   PROCEEDS UPON DEATH OF INSURED.  Upon the death of the Insured while
the Policy and this Agreement shall be in force, Best Lock and the Insured's
legal representatives shall promptly take all necessary steps, including
rendering such assistance as may reasonably be required by the other party, to
obtain payment from the Insurer of the amounts payable under the Policy.

    The Insurer shall be bound only by the provisions of the Policy, and any
payments made or action taken by it in accordance therewith shall fully
discharge it from all claims, suits and demands of all persons whatsoever.
Except as specifically provided by endorsement on the Policy, the Insurer shall
in no way be bound by the provisions of this Agreement.  Written receipt by the
Trustee for all death benefit proceeds received as the sole beneficiary shall be
a full discharge and release of the Insurer.

    6.   SURRENDER OR CANCELLATION OF POLICY, TERMINATION OF AGREEMENT.  The
Trustee shall have the sole right to surrender or cancel the Policy for the cash
surrender value thereof.  The Trustee


                                          3


and Best Lock agree that on any such surrender or cancellation of the Policy, or
upon the termination of this Agreement by the mutual consent of the parties
hereto, the Trustee shall pay to Best Lock an amount equal to Best Lock's Net
Interest determined as of the date of such surrender, cancellation or
termination.

    7.   TERMINATION OF AGREEMENT.  This Agreement shall terminate upon the
first to occur of any of the following events:

         a)   Surrender or cancellation of the Policy by the Trustee, or the
    termination of this Agreement by the mutual consent of the parties hereto
    in which event the provisions of paragraph 6 shall be operative;

         b)   The death of the Insured in which event the provisions of
    paragraph 4 and paragraph 5 shall be operative; or

         c)   Failure by Best Lock or the Trustee for any reason to make the
    contribution due toward any premiums payable on the Policy, resulting in
    the lapse of the Policy.

    Upon occurrence of any failure described in item (c) above, the Trustee
shall remit to Best Lock an amount equal to Best Lock's Net Interest with
respect to the Policy; PROVIDED, HOWEVER, that if only the Trustee (and not Best
Lock) fails to make a contribution due toward any premium payable on the Policy,
the Trustee shall remit to Best Lock an amount equal to the Cumulative
Investment Amount.  Thereafter, the Trustee shall become the absolute owner of
the Policy.

    8.   GENERAL PROVISIONS.

         a)   In the event of the termination of this Agreement pursuant to the
    provisions of paragraph 7 hereinabove, Best Lock shall release the
    Assignment of the Policy made to it, upon performance of all obligations of
    the Trustee hereunder.

         b    In the event that any party to this Agreement shall pay some
    portion of the premiums or interest due on the policy which such party
    shall not be obligated to pay, such amount or amounts shall become part of
    the amount due and owing to such party with respect to the Policy.

         c)   All previous agreements, if any, between the parties hereto with
    reference to the Policy are superseded by this Agreement.

         d)   This Agreement shall be binding upon the parties hereto and their
    successors, assigns, executors and administrators and beneficiaries.  This
    Agreement may be amended in writing only by the mutual consent of the
    parties hereto.

         e)   The Trustee shall have the right to assign all or any part of the
    Trustee's interest in this Agreement, and/or the Policy (including any and
    all of the Trustee's ownership rights in the Policy) to such other person,
    persons, entity or entities as the Trustee may desire.  Any assignee of the
    Trustee shall succeed to all of the rights, privileges, duties and
    obligations of the


                                          4


    Trustee as set forth herein.

         f)   This Agreement shall be subject to and construed according to the
    laws of the State of Indiana.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement on
the dates indicated below, but effective as of the date first above written.
