Plan Benefit” means the annuity equivalent of the benefit the Participant has

Plan (the “Savings Plan”) on account of Company matching contributions for each
year he is eligible to participate in the Savings Plan.  For this purpose, Company matching
contributions shall include:


1.)                                   the

Participant.

by the Company in Canada and participate in the IPSCO Inc. Canadian
Supplemental Retirement Benefit Plan, or any other Canadian pension arrangement
provided by the Company.


The Transferred Participant’s annual retirement benefit payable at
normal retirement, pursuant to Section 6, shall be frozen as of the date of
transfer to Canada.  Such frozen benefits
shall be calculated based on the Transferred Participant’s Continuous Service
and Earnings with respect to service rendered in the United States only as of
the date of transfer.  However, if the
Transferred Participant retires or terminates employment prior to his normal
retirement date and, thus, a benefit becomes payable pursuant to Section 7 or
8, respectively, for the purposes of determining the variables A and B therein,
Continuous Service shall include service rendered in Canada.


Section 2.                                            Purpose
and Intent.


The Company has
established the Plan for the purpose of providing pension supplements to senior
executives and certain group executives which, when combined with other
employment related benefits, will provide for the aggregate level of retirement
benefits specified herein.  The Plan is
intended to be “a plan which is unfunded and maintained by an employer
primarily for the purpose of providing deferred compensation for a select group
of management or highly



 4
 









compensated employees”
within the meaning of Sections 201(2), 301(a)(3), and 401(a)(1) of ERISA, and
shall be interpreted and administered in a manner consistent therewith.


The Plan as amended and
restated herein is a continuation of the Plan in effect immediately prior to
the Effective Date.  Any benefit payable
to a Participant whose Termination Date or death occurred prior to the
Effective Date shall be governed by the terms as in effect at the time of the
Participant’s Termination Date or death. 
The Plan as amended and restated herein is intended to comply with Code
Section 409A.

administered by the Company.  The Company
shall have the authority to interpret the provisions of the Plan and decide all
questions and settle all disputes that may arise in connection with the Plan,
all in the sole exercise of its reasonable discretion.  The Company may establish operative and
administrative rules and procedures in connection therewith, provided that such
procedures and rules are consistent with the requirements of section 503 of
ERISA.  All interpretations, decisions,
and determinations reasonably made by the Company shall be final, conclusive,
and binding on all persons concerned.

(i)                                     any
change, either through the issue, transfer, acquisition, conversion, exchange
or otherwise of shares, or through amalgamation, arrangement, merger or
otherwise (the “Transaction”), as a result of which the Company ceases to exist
as a separate legal entity and the beneficial shareholders of the Company
immediately before such change (not including any other party to the
Transaction or any such beneficial shareholder who was also a shareholder in
such other party before the Transaction) hold less that 50% of the shares or
other securities of the entity resulting from the change entitled to vote
generally in the election of the directors of the entity;


(ii)                                  any

as a result of which a Person or a group of Persons acting jointly or in concert
at arm’s length to the Company, either individually or together with its or
their associates and affiliates, beneficially owns more than 20% of all of the
common shares of the Company.  For
purposes of this clause (ii), the terms “associate”, “affiliate” and “beneficial
ownership” shall have the same respective meanings as in the Securities Act
(Ontario) as may be amended from time to time;


(iii)                               The
consummation of any transaction, whether by way of reorganization,

beneficial ownership of all or substantially all of the assets of the Company,
other than in a transaction that would result in:


(A)                              the
holders of common shares of the Company immediately prior to the completion of
such transaction (not including any such Person or any owner of such Person)
continuing to own more than 50% of the voting shares of the surviving entity
outstanding immediately following the completion of such transaction; and

having been members of the board of directors of the Company immediately prior
to the completion of such transaction; or


(iv)                              the

Board, if the election or appointment of such replacement directors has not
been approved by a majority of the members of the Board in office immediately
before such replacement.


If the Participant is employed by IPSCO Enterprises Inc., or a successor
subsidiary of the Employee in the United States, “Company” for purposes of this
definition of “Change in Control” shall mean either IPSCO Inc. or such United
States Subsidiary.  In no event will a
Change in Control be deemed to have occurred with respect to the Participant,
if an employee benefit plan maintained by the Company or the Participant is
part of a purchasing group that consummates the Change in Control
transaction.  The employee benefit plan
or the Participant will be deemed “part of a purchasing group” for purposes of
the preceding sentence if the plan or the Participant is an equity participant
in the purchasing company or group, but not including:  (i) passive ownership of less than two
percent (2%) of the stock of the purchasing company; or (ii) ownership of
equity participation in the purchasing company or group that is otherwise not
significant, as determined prior to the Change in Control by a majority of the

death of the Participant;


(B)                                the
Participant’s normal retirement pursuant to the normal retirement policies of
the Employer;



 9

incapable of performing his essential job duties and functions for a period of
six (6) months; or

immediately prior to any Change in Control or as such overall remuneration may
have been subsequently increased from time to time; or

investment plan, savings plan, incentive compensation plan or life insurance,
medical plans or disability plans provided by the Company to the Participant
and in which the Participant is participating under which the Participant is
covered, all as in effect immediately prior to any Change in Control or as such
benefit programs may have been subsequently increased from time to time, which
has not been replaced by benefit programs of any other person which the Participant
with equivalent benefits and value under equivalent terms and conditions as

payments guaranteed as described in Section 6(b).  Notwithstanding the foregoing, the
Participant may, prior to December 31, 2006 (or such later date permitted under

alternative form of payment, such as a lump sum, that is the Actuarial
Equivalent in value to the normal form of benefit.  Moreover, notwithstanding the foregoing, the

Conversion.


The final determination
of the amount of any benefit payable under the Plan shall be made in United
States currency.  All conversions of the
amount of the benefit payable from Canadian currency to United States currency
shall be based on the most recent CANSIM series B3400, or its successor,
rounded to the nearest 0.1 cent.


Notwithstanding the
foregoing, in the event that a higher benefit payable shall result from using
the average conversion rate in the twelve (12) month period preceding the
determination date, then such conversion rate yielding such higher benefit
payable shall be used.  The conversion at
payment shall be based on the most recent CANSIM rate.


Section 14.                                      Nature
of Claim for Payments.


Except as otherwise
provided in the Plan, the Company shall not be required to set aside or
segregate any assets of any kind to meet its obligations hereunder.  The Participant shall have no right on
account of the Plan in, or any specific assets of, the Company.  Any right to any payment the Participant may
have on account of the Plan shall be that of a general, unsecured creditor of
the Company.


The obligation of the
Company to pay benefits under the Plan shall be binding upon its successors,
assigns, whether by merger, consolidation, or acquisition of all or
substantially all of its business assets.


Notwithstanding the
foregoing, the Company may fund a portion of the benefit payable under the Plan
through the IPSCO Enterprises Inc. Executive Compensation Trust.  Assets in such trust shall at all times
remain subject to the claims of the Company’s creditors.


Section 15.                                      No
Assignment or Alienation.


The interest hereunder of
the Participant or Beneficiary shall not be alienable by the Participant or
Beneficiary by assignment or any other method and shall not be subject to, or
be taken by, his creditors by any process whatsoever, and any attempt to cause
such interest to be so subjected shall not be recognized, except to such extent
required by law.


Section 16.                                      No
Contract of Employment.


The Plan shall not
be deemed to constitute a contract of employment between the Company and the
Participant, or to be consideration for the employment of the Participant.  Neither the action of the Company in
establishing the Plan nor any action taken by the Company under the provisions
hereof, nor any provision of the Plan, shall be construed as giving to the
Participant the right to be retained in its employ or any right to any payment
whatsoever except to the extent of the benefits



 12
 









provided for by
the Plan.  The Company expressly reserves
its right at any time to dismiss the Participant without liability for any
claim against the Company for any payment whatsoever, except to the extent
provided for in the Plan. Notwithstanding the immediately preceding sentence,
the Company shall not pay out to the Participant any benefits provided under
this Plan in the event that the Participant is terminated for Cause as such
term is defined in Section 9 hereunder.


Section 17.                                      Amendment.


The Plan may be altered,
amended, or revoked in writing by the Company at any time, but such action may
not reduce the Company’s obligation with respect to the Participant below the
amount to which he would be entitled under the Plan as in effect immediately
prior to such alteration, amendment, or revocation.  Except as may be permitted under Code Section
409A, no alteration, amendment or revocation of the Plan shall directly or
indirectly accelerate a distribution to any Participant and the Company’s
obligation to the Participant shall continue until the obligation lapses in
accordance with the terms of the Plan immediately prior to such alteration,
amendment or revocation.


Section 18.                                      Claims
Procedure.


In the
event a Participant’s claim for benefits under the Plan is denied in whole or
in part by the Company, the Company will notify the Participant (or
Beneficiary) of the denial.  Such
notification will be made in writing, within 90 days of the date the claim is
received by the Company.  The
notification will include: (i) the specific reasons for the denial; (ii)
specific reference to the Plan provisions upon which the denial is based; (iii)
a description of any additional information necessary for the claimant to
perfect the claim and an explanation of why such material or information is
necessary; and (iv) an explanation of the applicable review procedures.

days from the date he or she receives notice of a claim denial to file a
written request for review of the denial with the Company.  The Company will review the claim denial and
inform the Participant (or Beneficiary) in writing of its decision within 60
days of the date the claim review request is received by the Company, unless
special circumstances require an extension of time, in which case, a decision
shall be rendered not later than 120 days after the receipt of a request for
review. Such decision shall be final and binding on the claimant.

Law.

governed and construed in accordance with the laws of the State of Illinois
except to the extent preempted by federal law.
