IDEXX LABORATORIES, INC.

AMENDED AND RESTATED AGREEMENT

           This Agreement, dated as of October 17, 2001, amends and restates in its entirety the Agreement dated as of August 26, 1999 between IDEXX Laboratories, Inc. ("IDEXX") and Xxxxx X. Xxxx ("Xxxx") regarding Xxxx'x reappointment as Chief Executive Officer of IDEXX, and the planned recruitment and appointment of a person to succeed Xxxx as such Chief Executive Officer. In consideration of Xxxx'x willingness to serve as Chief Executive Officer pending the identification and appointment of a successor (the "Succession"), and to serve as Executive Chairman for a period of time after the Succession, and for other good and valuable consideration, the parties agree as follows:

1.	From the date hereof until the earlier of the date of the Succession or June 30, 2002 (the
	"CEO Term"), Xxxx agrees to serve, and IDEXX agrees to retain Xxxx, as Chief
	Executive Officer, unless Xxxx resigns prior to expiration of the CEO Term. During the
	CEO Term, Xxxx will perform responsibilities consistent with his position as Chief
	Executive Officer and will assist in the recruitment of a successor.
2.	If and as long as requested by the Board of Directors, for the period from the end of the
	CEO Term to up to two years thereafter (such period, the "Executive Chairman Term"
	and together with the CEO Term, the "Term"), Xxxx agrees to serve as a part-time
	employee of IDEXX with the title of "Executive Chairman." During the Executive
	Chairman Term, Xxxx will perform part-time responsibilities consistent with his
	position as Executive Chairman, as mutually agreed with the Board of Directors. It is
	expected that such responsibilities will be primarily in the areas of strategy and
	acquisitions.
3.	Xxxx'x annual base salary during the CEO Term shall initially be $500,000, and will be
	subject to change during the CEO Term by mutual agreement. Eligibility for cash
	bonuses or stock option grants will be at the discretion of IDEXX's Board of Directors
	but consistent with senior officer guidelines. In consideration for Xxxx'x extended
	service to the Company since its inception and his willingness to assist with the
	succession, during the two-year period following the end of the CEO Term, regardless
	whether Xxxx is requested to serve as Executive Chairman, IDEXX shall pay to Xxxx
	an annual sum of $500,000, payable in equal bi-weekly installments, provided that
	payments under this sentence shall cease if and when Xxxx is entitled to any payment
	under the Employment Agreement dated April 25, 1997 between Xxxx and IDEXX (the
	"Employment Agreement") as a result of a Change of Control (as defined therein).
4.	During both the CEO Term and Executive Chairman Term, Xxxx will participate on the
	same basis and at the same level that he currently participates in IDEXX health
	insurance and other benefit programs, including the availability of on-site and off-site
	administrative support and office facilities.

5.	All of Xxxx'x options to purchase shares of IDEXX common stock shall become vested
	and exercisable in full upon the last day of the Term, unless he voluntarily resigns prior
	to the end of the Term.
6.	The Employment Agreement will remain in effect and, in the event of any conflict or
	inconsistency between this Agreement and such Employment Agreement, this
	Agreement shall control. For purposes of the Employment Agreement, from and after
	the end of the CEO Term: (a) the Employment Period shall be deemed to end upon
	expiration of the Executive Chairman Term, (b) the responsibilities of Xxxx shall be as
	set forth in this Agreement rather than Section 4 of the Employment Agreement, and (c)
	Xxxx'x "Annual Base Salary" for purposes of Section 6(a)(i)(B) of the Employment
	Agreement shall mean Xxxx'x annual base salary as of the end of the CEO Term.

Agreed to as of October 17, 2001.
