        NOW, THEREFORE:


        1. Subject to the terms and conditions of the Policy and to any superior
liens that the Insurer may have against the Policy, the Assignor hereby assigns
to the Assignee the following specific rights in and to the Policy:

                (a) The right to obtain, upon surrender of the Policy by the
Assignor, an amount from the surrender proceeds equal to but not exceeding the
amount of the Assignee's Interest in the Policy, (as defined below). If, (1) the
Assignor borrows any amounts from the cash surrender value of the Policy and (2)
upon a surrender of the Policy by the Assignor, the amount of the Assignee's
Interest in the Policy exceeds the surrender proceeds, any shortfall shall be
paid to the Assignee by the Insureds (or either one of them).

                (b) The right to collect, upon a claim by the Assignor under the
Policy by reason of the death of the Insureds, an amount from the proceeds equal
to but not exceeding the amount of the Assignee's Interest in the Policy (as
defined below) determined immediately prior to the death of the survivor of the
Insureds.

        The amount of the Assignee's Interest in the Policy, wherever referred
to in this Assignment, is an amount equal to the lesser of (a) the net cash
surrender value of the Policy as calculated without giving regard to any premium
payments which may have been paid by either or both of the Insureds or by any
trust created by either of both of the Insureds and (b) the aggregate amount of
premiums paid by the Assignee on the Policy, and in each case reduced by the
aggregate amount, if any, paid by or on behalf of the Assignor to the Assignee
in reimbursement of premiums paid by the Employer on the Policy. Notwithstanding
the foregoing, if at any time this Assignment is in effect, the Assignor borrows
any amounts from the cash surrender value of the Policy, the Assignee's Interest
in the Policy, wherever referred to in this Assignment, is an amount equal to
the aggregate amount of premiums paid by the Assignee on the Policy reduced by
the aggregate amount, if any, paid by or on behalf of the Assignor to the
Assignee in reimbursement of premiums paid by the Assignee on the Policy.


        2. The Assignor will continue to possess and exercise exclusively all
remaining rights in and to the Policy not otherwise assigned to the Assignee by
reason of this Assignment, including, without limitation, the right to assign
the Policy to a third party, the right to designate the beneficiary or
beneficiaries of any death benefit in excess of the Assignee's Interest in the
Policy, the right to surrender the Policy and the right to reduce the death
benefit payable


                                       2

under the Policy (provided, however, that the death benefit may not be reduced
to an amount less than the aggregate amount of premiums paid by the Assignee on
the Policy). In addition, the Assignor shall have the right to borrow from the
cash surrender value of the policy; provided, however, that the Assignor may
borrow only to the extent that immediately after any such borrowing the cash
surrender value of the Policy shall be no less than the aggregate amount of
premiums paid by the Assignee on the Policy reduced by the aggregate amount, if
any, paid by or on behalf of the Assignor to the Assignee in reimbursement of
premiums paid by the Assignee on the Policy. The Assignor agrees to notify the
Assignee of any assignment of its rights in and to the Policy, in whole or in
part.



        3. The Assignee will pay all premiums due on the Policy to the Insurer
on or before the date or dates on which they become due through January 31,
1998, at which time the Assignee's obligation to pay said premiums shall cease.


        4. The Assignee will not exercise its rights in and to the Policy in any
way that may conflict with the exercise by the Assignor of its rights in and to
the Policy or that may delay or otherwise interfere with receipt by its
designated beneficiary or beneficiaries of any death benefit under the Policy in
excess of the Assignee's Interest in the Policy. The Assignee will not assign
its rights in and to the Policy to any person other than the Assignor without
the prior consent of the Assignor.


        5. The Insurer is hereby authorized to recognize the Assignee's claim to
rights hereunder without investigating the reason for any action taken by the
Assignee or giving any notice. If the Insurer deems that the sole signature of
the Assignee is insufficient for the exercise of the Assignee's rights under the
Policy assigned hereby, the Assignor agrees to execute any documents, papers or
checks necessary to facilitate the Assignee's exercise of its rights under the
Policy.


        6. Upon receipt by the Assignee of an amount equal to the Assignee's
Interest in the Policy, the Assignee will execute such documents as may be
reasonably required by the Assignor to release the Assignee's rights in and to
the Policy.


        7. This Assignment will be governed by and construed in accordance with
the laws of the State of New York applicable to contracts made and to be
performed wholly in that state.

        8. This Assignment will benefit and bind the heirs, executors,
administrators, personal representatives, successors and assigns of each of the
parties. Notwithstanding the foregoing, the Assignor is entering into this
Agreement solely in their capacity as Trustees and not individually.


        9. This Assignment may be executed in counterparts, each of which will
be an original, which together will constitute one Assignment.



        IN WITNESS WHEREOF, the parties have caused this Assignment to be
executed on the day first written above.
