ITEM  1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

(a)   Executive Retirement and Severance Benefits Agreements

            On January 27, 2005, GSI Lumonics Inc. entered into an Executive
Retirement and Severance Benefits Agreement with the following executive
officers: Thomas Swain, Vice President, Finance and CFO, Linda Palmer, Vice
President, Corporate Resources, and Felix Stukalin, Vice President, Business
Development (each, an "Executive"). Each Executive entered into the same form of
Executive Retirement and Severance Benefits Agreement with GSI Lumonics Inc. A
copy of the form of Executive Retirement and Severance Benefits Agreement is
attached hereto as Exhibit 10.1 (the "Agreement") and is incorporated herein in
its entirety. Each Agreement contains the following material terms and
conditions:

- Each Agreement became effective as of January 17, 2005 and continues in effect
for a period of 5 years with an automatic renewal for an additional period of
three years unless, no later than 1 year prior to the end of the initial 5 year
term, GSI Lumonics delivers written notice of termination to the Executive.

- If the Executive reaches the age of sixty (60) and has a minimum of fifteen
(15) years service with GSI Lumonics, then such Executive can elect to retire,
provided a notice to such effect is provided to the CEO not less than one (1)
year prior to the date of retirement specified in the notice. In such an event,
the Executive will receive the following retirement benefits, provided that the
Executive continues to comply with any post-retirement obligations such
Executive has to GSI Lumonics: the Executive may elect for GSI Lumonics to
retain the Executive for part-time employment for up to three (3) years from the
Executive's retirement date, and such part-time employment shall not be more
than fifty percent (50%) of full-time; continued health and dental group
benefits to the Executive and the Executive's family at the same level as was
provided to the Executive as of the Executive's retirement date; and all stock
options granted to the Executive prior to such retirement shall continue to vest
during the period of such part-time employment. If the Executive retires and
chooses any of these retirement benefits, such Executive will not be eligible
for termination benefits (as described below).

- If the Executive is terminated by GSI Lumonics for any reason other than
death, disability, or cause (all as defined in the Agreement) or the Executive
terminates his or her employment with GSI Lumonics for good reason (as defined
in the Agreement), then the Executive shall receive the following termination
benefits: eighteen (18) months of base salary, and continued health and dental
group benefits to the Executive and the Executive's family at the same level as
was provided to the Executive as of the Executive's termination date for the
earlier of two (2) years or employment by another company which provides health
and dental insurance benefits to the Executive. These termination benefits are
conditioned upon the Executive signing a release of claims and compliance with
all post-termination obligations the Executive has to GSI Lumonics. No such
benefits are available upon the resignation (other than for good cause) or
retirement of the Executive.



- Upon the death of the Executive, the Executive's heirs will be entitled to
receive the Executive's termination benefits provided such heirs sign a release
of claims as described in the Agreement.

- During the Executive's part-time employment and for a period of one year
thereafter, or during the period that the Executive is eligible to receive
termination benefits and for a period of one year thereafter, the Executive is
prohibited, without GSI Lumonics' prior written consent, from competing with GSI
Lumonics or soliciting employees from GSI Lumonics.

- All claims for any benefits under the Agreement shall be determined by the
Board of Directors of GSI Lumonics. All disputes shall be settled exclusively by
binding arbitration in Boston, Massachusetts, U.S.A.
