Mr. Charles D. Winston
c/o GSI Lumonics Inc.
130 Lombard Street
Oxnard, CA, 93030, U.S.A.

Dear Mr. Winston:

GSI Lumonics recognizes that uncertainties relating to job security could result
in the resignation or possible distraction of key management personnel to the
detriment of the Company and its shareholders.  Accordingly, the Company wishes
to clarify certain arrangements that will apply in the event your employment by
the Company is terminated, especially in circumstances relating to a Change of
Control.  In particular, the Company believes it important, should a proposal be
received that could result in a change in the ownership of the Company, that
your employment with the Company or its affiliates be continued during the
pendency of such proposal and that you be able to assess and advise the Company
and its shareholders and to take such other action regarding such proposal as
the Board might determine to be appropriate, without being influenced by the
uncertainties of your own situation.

Therefore, this letter agreement ("Agreement") sets forth the severance and
termination benefits which the Company agrees will be provided to you in the
event your employment with the Company is terminated without Cause either prior
to or following a Change of Control.  Please note that this Agreement revokes
and supersedes all other prior agreements between you and the Company dealing
with the benefits to be given to you in the event your employment with the
Company is terminated without Cause either prior to, or following, a Change of
Control.

Mr. Michael R. Kampfe
c/o GSI Lumonics Inc.
60 Fordham Road
Wilmington, MA, 01887, U.S.A.

Dear Mr. Kampfe:

GSI Lumonics recognizes that uncertainties relating to job security could result
in the resignation or possible distraction of key management personnel to the
detriment of the Company and its shareholders.  Accordingly, the Company wishes
to clarify certain arrangements that will apply in the event your employment by
the Company is terminated, especially in circumstances relating to a Change of
Control.  In particular, the Company believes it important, should a proposal be
received that could result in a change in the ownership of the Company, that
your employment with the Company or its affiliates be continued during the
pendency of such proposal and that you be able to assess and advise the Company
and its shareholders and to take such other action regarding such proposal as
the Board might determine to be appropriate, without being influenced by the
uncertainties of your own situation.

Therefore, this letter agreement ("Agreement") sets forth the severance and
termination benefits which the Company agrees will be provided to you in the
event your employment with the Company is terminated without Cause either prior
to or following a Change of Control.  Please note that this Agreement revokes
and supersedes all other prior agreements between you and the Company dealing
with the benefits to be given to you in the event your employment with the
Company is terminated without Cause either prior to, or following, a Change of
Control.
