a select group of management employees for purposes of Title I of the Employee
Retirement Income Security Act of 1974. This document restates the Plan
primarily for the purpose of complying with the applicable requirements of
Section 409A of the Internal Revenue Code of 1986, and Proposed Regulations
§§1.409A-1 et seq. thereunder.

selected by the Participant. All amounts credited to the IDEXX Stock Investment
Account shall be converted into Deferred Stock Units, each representing a
notional interest in one share of IDEXX Stock. The number of Deferred Stock
Units credited to a Participant’s account with respect to a deferral shall be
determined by dividing the amount of the deferral by the closing price of one

last trading day prior to the event with respect to which the distribution is
made.

    (b)        Benefits under the Plan shall be distributed to a Participant in
a single lump sum or pursuant to a fixed schedule of payments upon the event or

    (ii)        the date the Participant becomes Disabled;

    (iii)        the Participant’s date of death;

    (iv)       the time specified by the Participant in his or her deferral

consistent with applicable law;

Participants upon the occurrence of a Change in Control of the Company;

to an Executive who is a “specified employee” (within the meaning of Section

date of his or her separation from service for any reason or, if earlier, his or
her death;

determines that a Participant has experienced an Unforeseeable Emergency, the
Plan Administrator may authorize the distribution of all or a portion of the
Participant’s benefit under the Plan. The amount distributed with respect to the
Unforeseeable Emergency must not exceed the amounts necessary to satisfy such
emergency plus amounts necessary to pay taxes reasonably anticipated as a result
of the distribution, after taking into account the extent to which such hardship
is or may be relieved through reimbursement or compensation by insurance or
otherwise or by liquidation of the Participant’s assets (to the extent the
liquidation of such assets would not itself cause severe financial hardship).
