3.12 Employee Matters and Company Employee Plans.
Parent acknowledges that the Company employs a significant
percentage of its workforce in Canada, and as such U.S. laws governing
employment and employee benefit plans will not apply, and many of the
benefit plans referred to in this section will not exist for the
Company's Canadian employees.  With that understanding, the Company
makes the following representations: Part 3.12 of the Disclosure Letter
contains a complete and accurate list of the following information for
each Employee or consultant of the Company, including: each Employee on
leave of absence or layoff status:  name; job title; aggregate annual
remuneration (gross salary); vacation accrued; and service credited for
purposes of vesting and eligibility to participate under a Company
Employee Plan or any retirement, severance pay or employee benefit
plan.  For the purposes hereof "remuneration" includes bonuses but
excludes non-monetary fringe benefits and additional costs to the
Company in respect of remuneration.

Affiliate"), all Company Employee Plans including (i) all Pension Plans
whether or not such plans are subject to ERISA or any applicable
Canadian law pertaining to such plans, (ii) each loan to a non-officer
employee, loans to officers and directors and any Incentive Plans,

that apply to senior management or employees located outside the United

and (v) any current or former employment or executive compensation or
severance agreements, written or otherwise, as to which unsatisfied or

with respect to each Company Employee Plan which is subject to ERISA
reporting requirements or any applicable Canadian law, provided copies
of the Form 5500 reports or any reports required by applicable Canadian
law filed for the last three plan years.  Any Company Employee Plan
intended to be qualified under Section 401(a) of the Code or registered
under any applicable Canadian pension benefits legislation has either
obtained from the Internal Revenue Service or the applicable Canadian
regulatory authorities a favorable determination letter as to its
qualified status under the Code or similar approval under any
applicable Canadian law, including all amendments to the Code effected
by the Tax Reform Act of 1986 and subsequent legislation  (or relies on
such favorable determination letter issued by the Internal Revenue
Service with respect to a prototype plan adopted by the Company), or
has applied to the Internal Revenue Service for such a determination
letter or approval prior to the expiration of the requisite period
under applicable Treasury Regulations or Internal Revenue Service
pronouncements in which to apply for such determination letter or
approval and to make any amendments necessary to obtain a favorable
determination or approval.  The Company has also furnished Parent with
the most recent Internal Revenue Service determination letter or any
similar Canadian approval issued or relied upon with respect to each
such Company Employee Plan, and nothing has occurred since the issuance
of each such letter or approval which could reasonably be expected to
cause the loss of the tax-qualified status of any Company Employee Plan
subject to Code Section 401(a) or Canadian pension benefits legislation
or the Income Tax Act  (Canada).
(c) (A) Other than continued health care coverage
required under the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended ("COBRA") or applicable employment standards
legislation of any Canadian province, none of the Company Employee
Plans promises or provides retiree medical or other retiree welfare or
non-pension benefits to any person; (B) there has been no "prohibited
transaction" or other similar event, as such are defined in Section 406
of ERISA and Section 4975 of the Code or any analogous Canadian law,
with respect to any Company Employee Plan, which could reasonably be
expected to have, in the aggregate, a Material Adverse Effect on the
Company; (C) each Company Employee Plan has been administered in
accordance with its terms and in compliance with the requirements
prescribed by any and all statutes, rules and regulations (including
ERISA, the Code or any applicable Canadian law), and the Company and

required to be performed by them under, are not in any respect in
default under or violation of, and have no knowledge of any default or
violation by any other party to, any of the Company Employee Plans;
(D) neither the Company nor its subsidiary or ERISA Affiliate is
subject to any liability or penalty under Sections 4976 through 4980 of
the Code, Title I of ERISA or any applicable Canadian law with respect
to any of the Company Employee Plans and which individually or in the
aggregate could reasonably be expected to have a Material Adverse
Effect on the Company; (E) all material contributions required to be
made by the Company or its subsidiary or ERISA Affiliate to any Company
Employee Plan have been made on or before their due dates and a
reasonable amount has been accrued for contributions to each Company
Employee Plan for the current plan years; (F) with respect to each
Company Employee Plan, no "reportable event" within the meaning of
Section 4043 of ERISA (excluding any such event for which the thirty
(30) day notice requirement has been waived under the regulations to
Section 4043 of ERISA) nor any event described in Section 4062, 4063 or
4041 or ERISA, nor any event under Canadian law has occurred which
would entitle any Person to partially or fully wind-up or require the
partial or full winding-up of any Company Employee Plan or Pension Plan
which could adversely affect the tax status of any Company Employee
Plan; and (G) no Company Employee Plan is covered by, and neither the
Company nor its subsidiary or ERISA Affiliate has incurred or expects
to incur any liability under Title IV of ERISA, Section 412 of the
Code.  All Company Employee Plans which are required to be are fully
funded and have been invested in accordance with the relevant terms of
each plan and all applicable law, and, in the case of Pension Plans,
are fully funded on a going concern and solvency basis in accordance
with generally accepted actuarial principles and actuarial methods and
assumptions contained in the most recent actuarial report of the plan.
With respect to each Company Employee Plan subject to ERISA as either
an employee pension plan within the meaning of Section 3(2) of ERISA or
an employee welfare benefit plan within the meaning of Section 3(l) of
ERISA, and any Pension Plan registered under applicable Canadian law,
the Company has prepared in good faith and timely filed all requisite
governmental reports (which were true and correct as of the date filed)
and the Company has properly and timely filed and distributed or posted
all notices and reports to employees required to be filed, distributed
or posted with respect to each such Company Employee Plan.  No suit,
administrative proceeding, action or other litigation has been brought,
or is threatened, against or with respect to any such Company Employee
Plan, including any audit or inquiry by the IRS, United States
Department of Labor or any analogous Canadian authority.  Neither the
Company nor its subsidiary or other ERISA Affiliate is a party to, or
has made any contribution to or otherwise incurred any obligation
under, any "multiemployer plan" as defined in Section 3(37) of ERISA,
or any similar provisions of Canadian law.
(d) With respect to each Company Employee Plan, the
Company has complied with the applicable health care continuation and
notice provisions of COBRA and the proposed regulations thereunder and
any applicable provisions of the employment standards legislation of
any Canadian province, except to the extent that such failure to comply
would not have a Material Adverse Effect.
(e) The consummation of the transactions
contemplated by this Agreement will not (A) entitle any current or
former employee or other service provider of the Company, its
subsidiary or any other ERISA Affiliate to severance benefits or any
other payment,  or (B) accelerate the time of payment or vesting, or
increase the amount of compensation due any such employee or service
provider.
(f) There has been no amendment to, written
interpretation or announcement (whether or not written) by the Company,
its subsidiary or other ERISA Affiliate relating to, or change in
participation or coverage under, any Company Employee Plan which would
materially increase the expense of maintaining such Plan above the
level of expense incurred with respect to that Plan for the most recent
fiscal year included in the Company's financial statements.
(g) Each Company International Employee Plan has
been established, maintained and administered in compliance with its
terms and conditions and with the requirements prescribed by any and
all statutory or regulatory laws applicable to such International
Employee Plan, except to the extent that such failure to comply would
not have a Material Adverse Effect.  No Company International Employee

counsel in accordance with the provision of the preceding sentence,
(ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified
party within a reasonable time after the notice of the commencement of
the action, or (iii) the indemnifying party has authorized the

through the failure of Parent to comply with its obligations under this

9.2 Effect of Termination.

is terminated by a party because of the Breach of the Agreement by the
other party or because one or more of the conditions to the terminating
party's obligations under this Agreement is not satisfied as a result
of the other party's failure to comply with its obligations under this
Agreement, the terminating party's right to pursue all legal remedies
will survive such termination unimpaired, subject to the provisions of
Section 11.1 hereof.

10. Escrow Fund.
10.1 Escrow Shares.
As soon as practicable after the Effective Time, the number of
Exchangeable Shares set forth opposite the name of each Founder in
Annex C to the Escrow Agreement having a value of $3,800,000
(collectively the "Escrow Shares") shall be registered in the name of,
and be deposited with The Bank of Nova Scotia Trust Company of New York
(the "Depositary Agent"), such deposit to constitute the escrow fund
(the "Escrow Fund") and to be governed by the terms set forth herein
and in the Escrow Agreement attached hereto as Exhibit H (the "Escrow
Agreement").  The Escrow Fund (but only up to a maximum of the value of
the Escrow Shares) shall be the exclusive remedy of Parent for a breach
of a representation or warranty by Company and shall be available to
compensate Parent for any loss, liability, claim, damage (including
incidental and consequential damages), expense (including costs of
investigation and defense and reasonable attorneys' fees) or diminution
of value, whether or not involving a third-party claim (collectively,
"Damages"), arising, directly or indirectly, from or in connection
with:
(a) any Breach of any representation or warranty
made by the Company in this Agreement as if such representation or
warranty were made on and as of the Closing Date, other than any such
Breach that is disclosed in a supplement to the Disclosure Letter;
(b) any Breach by the Company of any covenant or
obligation of the Company in this Agreement that is not waived on or
prior to Closing; or
(c) resolution or settlement of any Proceeding
arising out of the claims described in Part 3.14(b) of the Disclosure
Letter.
Parent and its affiliates shall act in good faith and in a
commercially reasonable manner, taking into account the needs of
Parent's then consolidated business and duties it owes to all of its
equity holders, to mitigate any Damages they may suffer.  Any claim for
indemnification for Damages hereunder shall be offset or reduced by
(i) any tax benefit received by Parent or its affiliates as a result of
such Damages and (ii) in the case of third-party claims, by any amount
actually recovered by Parent or its affiliates pursuant to
counterclaims made by any of them directly relating to the facts giving
rise to such third-party claims.
Parent and Company each acknowledge that such Damages, if any,
would relate to unresolved contingencies existing at the Closing, which
if resolved at the Closing would have led to a reduction in the total
number of shares Parent would have agreed to issue in connection with
the Contemplated Transactions.
10.2 Damage Threshold.
Notwithstanding the foregoing, Parent may not receive any shares
from the Escrow Fund unless and until an Officer's Certificate or
Certificates (as defined in Section 10.4 below) identifying Damages the
aggregate amount of which exceeds $100,000 has been delivered to the
Depositary Agent as provided in Section 10.4 below and such amount is
determined pursuant to this Article 10 to be payable, in which case
Parent shall receive shares equal in value to the full amount of the
Damages; provided, however, that in no event shall Parent receive more
than the Escrow Shares.
10.3 Escrow Period.
The Escrow Period shall terminate with respect to the Escrow
Shares upon the second anniversary of the Closing Date provided that
this escrow shall terminate with respect to 50% of the Escrow Shares on
the first anniversary of the Closing Date, and such Escrow Shares shall
be released by the Depositary Agent; provided, however, that a portion
of the Escrow Shares, which, in the reasonable judgment of Parent,
subject to the objection of the Company Agent (as defined in
Section 10.7 below) and the subsequent arbitration of the matter in the
manner provided in Section 10.6 hereof, are necessary to satisfy any
unsatisfied claims specified in any Officer's Certificate theretofore
delivered to the Depositary Agent prior to termination of the Escrow
Period with respect to the facts and circumstances existing prior to
expiration of the Escrow Period, shall remain in the Escrow Fund until
such claims have been resolved.  Any and all releases of the Escrow
Shares upon termination of the Escrow Period shall be released to the
Holder's Accounts held by the Depository Agent for the Founders
according to the terms of the Escrow Agreement.
10.4 Claims upon Escrow Fund.
(a) Upon receipt by the Depositary Agent on or
before the last day of the Escrow Period of a certificate signed by the
Chief Executive Officer, the President, the Chief Financial Officer or
the General Counsel of Parent (an "Officer's Certificate"):
 (i) stating that Damages exist in an
aggregate amount greater than $100,000, and
 (ii) specifying in reasonable detail the
individual items of such Damages included in the amount so stated, the
date each such item was paid, or properly accrued or arose, the nature
of the misrepresentation, breach of warranty or claim to which such
item is related, the Depositary Agent shall, subject to the provisions
of Article 10 hereof, transfer and deliver to Parent out of the Escrow
Fund, as promptly as practicable, Escrow Shares whose value is equal to
the amount of the Damage.
(b) For the purpose of compensating Parent for its
Damages pursuant to this Agreement, the Exchangeable Shares in the
Escrow Fund shall be valued at $48.77 per share (as adjusted for stock
splits, reverse stock splits and similar events).  Parent and Company
understand that the variation in the trading price of Parent's stock
may cause the number of shares required to satisfy an escrow claim to
differ from the amount of shares calculated based on the fair market
value of such shares on the date such claim is made.
10.5 Objections to Claims.
At the time of delivery of any Officer's Certificate to the
Depositary Agent, a duplicate copy of such Officer's Certificate shall
be delivered to the Company Agent (defined in Section 10.7 below) and
for a period of thirty (30) days after such delivery, the Depositary
Agent shall make no transfer or delivery of Escrow Shares pursuant to
Section 10.4 hereof unless the Depositary Agent shall have received
written authorization from the Company Agent to make such delivery.
After the expiration of such thirty (30) day period, the Depositary
Agent shall make transfer and delivery of the Escrow Shares in
accordance with Section 10.4 hereof, provided that no such payment,
transfer or delivery may be made if the Company Agent shall object in a
written statement to the claim made in the Officer's Certificate, and
such statement shall have been delivered to the Depositary Agent and to
Parent prior to the expiration of such thirty (30) day period.
10.6 Resolution of Conflicts; Arbitration.
(a) In case the Company Agent shall so object in
writing to any claim or claims by Parent made in any Officer's
Certificate, Parent shall have forty-five (45) days to respond in a
written statement to the objection of the Company Agent.  If after such
forty-five (45) day period there remains a dispute as to any claims,
the Company Agent and Parent shall attempt in good faith for sixty (60)
days to agree upon the rights of the respective parties with respect to
each of such claims.  If the Company Agent and Parent should so agree,
a memorandum setting forth such agreement shall be prepared and signed
by both parties and shall be furnished to the Depositary Agent.  The
Depositary Agent shall be entitled to rely on any such memorandum and
shall distribute the Escrow Shares from the Escrow Fund in accordance
with the terms thereof.
(b) If no such agreement can be reached after good
faith negotiation, either Parent or the Company Agent may, by written
notice to the other, demand arbitration of the matter unless the amount
of the damage or loss is at issue in pending litigation with a third
party, in which event arbitration shall not be commenced until such
amount is ascertained or both parties agree to arbitration; and in
either such event the matter shall be settled by arbitration conducted
by one arbitrator.  Within fifteen (15) days after such written notice
is sent, Parent and the Company Agent shall together select one
arbitrator, failing which, Parent and Company Agent shall apply to a
California court to appoint one arbitrator.  The decision of the
arbitrator as to the validity and amount of any claim in such Officer's
Certificate shall be binding and conclusive upon the parties to this
Agreement, and notwithstanding anything in Section 10.6 hereof, the
Depositary Agent shall be entitled to act in accordance with such
decision and make or withhold payments out of the Escrow Fund in
accordance therewith.
(c) Judgment upon any award rendered by the
arbitrator may be entered in any court having jurisdiction.  Any such
arbitration shall be held in Cupertino, California under the commercial
rules then in effect of the American Arbitration Association.  For
purposes of this Section 10.6(c), in any arbitration hereunder in which
any claim or the amount thereof stated in the Officer's Certificate is
at issue, Parent shall be deemed to be the Non-Prevailing Party unless
the arbitrator awards Parent more than one-half (1/2) of the amount in
dispute; otherwise, the Company shareholders for whom the Escrow Shares
otherwise issuable to them have been deposited in the Escrow Fund shall
be deemed to be the Non-Prevailing Party.  The Non-Prevailing Party to
an arbitration shall pay its own expenses, the fees of each arbitrator,
the administrative fee of the American Arbitration Association, and the
expenses, including without limitation, attorneys' fees and costs,
reasonably incurred by the other party to the arbitration.
10.7 Company Agent.
(a) James McGee shall be constituted and appointed
as agent ("Company Agent") for and on behalf of the Company
shareholders to give and receive notices and communications, to
authorize transfer and delivery to Parent of the Escrow Shares in
satisfaction of claims by Parent, to object to such transfers and
deliveries, to agree to, negotiate, enter into settlements and
compromises of, and demand arbitration and comply with orders of courts
and awards of arbitrators with respect to such claims, and to take all
actions necessary or appropriate in the judgment of the Company Agent
for the accomplishment of the foregoing.  Such agency may be changed by
the holders of a majority in interest of the Escrow Fund from time to
time upon not less than 10 days' prior written notice to Parent.  No
bond shall be required of the Company Agent, and the Company Agent
shall receive no compensation for his services.  Notices or
communications to or from the Company Agent shall constitute notice to
or from each of the Company's shareholders.
(b) The Company Agent shall not be liable for any
act done or omitted hereunder, as the Company Agent while acting in
good faith and in the exercise of reasonable judgment, and any act done
or omitted pursuant to the advice of counsel shall be conclusive
evidence of such good faith.  The Company shareholders shall severally
indemnify the Company Agent and hold him harmless against any loss,
liability or expense incurred without gross negligence or bad faith on
the part of the Company Agent and arising out of or in connection with
the acceptance or administration of his duties hereunder.
(c) The Company Agent shall have reasonable access
to information about the Company and the reasonable assistance of the
Company's and Acquisition Sub's officers and employees for purposes of
performing its duties and exercising its rights hereunder, provided
that the Company Agent shall treat confidentially and not disclose any
nonpublic information from or about the Company to anyone (except on a
need to know basis to individuals who agree to treat such information
confidentially).
10.8 Actions of the Company Agent.
A decision, act, consent or instruction of the Company Agent
shall constitute a decision of all Company shareholders for whom Escrow
Shares otherwise issuable to them are deposited in the Escrow Fund and
shall be final, binding and conclusive upon each such Company
shareholder, and the Depositary Agent and Parent may rely upon any
decision, act, consent or instruction of the Company Agent as being the
decision, act, consent or instruction of each and every such Company
shareholder.  The Depositary Agent and Parent are hereby relieved from
any liability to any person for any acts done by them in accordance
with such decision, act, consent or instruction of the Company Agent.
10.9 Third-Party Claims.
In the event Parent becomes aware of a third-party claim which
Parent believes may result in a demand against the Escrow Fund, Parent
shall promptly notify the Company Agent of such claim and provide
details thereof, and the Company Agent shall be entitled, at its
expense, to participate in or assume control of any defense of such
claim.  If the Company Agent elects to assume control of the defense,
Parent shall have the right to participate in the defense and Parent
shall have the right in its sole discretion to settle any such claim;
provided, however, that Parent may not effect the settlement of any
such claim without the consent of the Company Agent, which consent
shall not be unreasonably withheld.  In the event that the Company
Agent has consented to any such settlement, the Company Agent shall
have no power or authority to object under Section 10.5 or any other
provision of this Article X to the amount of any claim by Parent
against the Escrow Fund for indemnity with respect to such settlement.

2.2.2.4.        there will be added to the stated capital
account in the accounting records of New ObjecTime
maintained for the New ObjecTime Common Shares an amount
equal to the aggregate of (a) the stated capital of the
common shares of Amalco, and (b) the amount obtained by
multiplying the stated capital of the ObjecTime Shares as of
the Effective Time by the number of issued and outstanding
ObjecTime Shares (i) deemed to be held by Holding ULC
pursuant to section 3.1.2 and (ii) held by Rational or its
Affiliates, and dividing that product by the number of
issued and outstanding ObjecTime Shares as of that time;
there will be added to the stated capital account in the
accounting records of New ObjecTime maintained for the New
ObjecTime Preference Shares an amount equal to the stated
capital of the preference shares of Amalco; and, there will
be added to the stated capital account in the accounting
records of Acquisition Sub maintained for the Class B
Non-Voting Preference Shares an amount equal to the
aggregate of the amount obtained by multiplying the stated
capital of the ObjecTime Shares as of the Effective Time by
the number of issued and outstanding ObjecTime Shares as of
that time (other than those (i) deemed to be held by Holding
ULC pursuant to section 3.1.2 or (ii) held by Rational or
its Affiliates), and dividing that product by the number of
issued and outstanding ObjecTime Shares as of that time;
2.2.3.  immediately after the Amalgamation, Acquisition Sub will
effect the following capital reorganization:
2.2.3.1.        one-third (1/3) of the outstanding Class B
Non-Voting Preference Shares held by each Person who is not
a resident of Canada for the purposes of the ITA (rounded up
to the nearest whole share) will be deemed to have been
transferred by the holder to Holding ULC in exchange for
cash equal to the Rational Common Share Price for each
Class B Non-Voting Preference Share transferred and each
remaining outstanding Class B Non-Voting Preference Share
held by a Person who is not a resident of Canada for the
purposes of the ITA will be deemed to have been transferred
by the holder to Holding ULC in exchange for one fully paid
and non-assessable Rational Common Share and the name of
those transferring holders will be removed from the register
of holders of Class B Non-Voting Preference Shares and added
to the register of holders of Rational Common Shares and
Holding ULC will be recorded as the registered holder of the
Class B Non-Voting Preference Shares so exchanged and will
be deemed to be the legal and beneficial owner of those
shares;
2.2.3.2.        one-third (1/3) of the outstanding Class B
Non-Voting Preference Shares held by each Person who is a
resident of Canada for the purposes of the ITA (rounded up
to the nearest whole share) will be deemed to have been
transferred by the holder to Holding ULC in exchange for
cash equal to the Rational Common Share Price for each
Class B Non-Voting Preference Share transferred and Holding
ULC will be recorded as the registered holder of the Class B
Non-Voting Preference Shares so exchanged and will be deemed
to be the legal and beneficial owner of those shares;
2.2.3.3.        each remaining outstanding Clas- B Non-Voting
Preference Share held by a Person who is a resident of
Canada for the purposes of the ITA will be deemed to have
been transferred by the holder to Acquisition Sub in
exchange for one fully paid and non-assessable Exchangeable
Share and the name of that holder will be removed from the
register of holders of Class B Non-Voting Preference Shares
and added to the register of holders of Exchangeable Shares;
2.2.3.4.        the Clas- B Non-Voting Preference Shares
transferred to Acquisition Sub pursuant to section 2.2.3.3
will be cancelled and each Class B Non-Voting Preference
Share transferred to Holding ULC pursuant to section 2.2.3.1
or 2.2.3.2 will be exchanged for one fully paid and non-
assessable common share of Acquisition Sub, Holding ULC will
be recorded as the registered holder of those common shares
of Acquisition Sub, and the Class B Non-Voting Preference
Shares so exchanged will be cancelled; and
2.2.3.5.        the stated capital accounts of Acquisition Sub
will be adjusted as follows:
2.2.3.5.1.      there will be deducted from the stated
capital account in the accounting records of
Acquisition Sub maintained for the Class B Non-Voting
Preference Shares an amount equal to the number
obtained by multiplying the stated capital of the
Class B Non-Voting Preference Shares, calculated as
set out in section 2.2.2.4, by the number of issued
and outstanding Class B Non-Voting Preference Shares
transferred to Acquisition Sub pursuant to
section 2.2.3.3 and dividing that product by the
number of Class B Non-Voting Preference Shares issued
on the Amalgamation;
2.2.3.5.2.      there will be added to the stated capital
account in the accounting records of Acquisition Sub
maintained for the Exchangeable Shares an amount equal
to the amount deducted pursuant to section 2.2.3.5.1
from the stated capital account maintained for the
Class B Non-Voting Preference Shares;
2.2.3.5.3.      there will be deducted from the stated
capital account in the accounting records of
Acquisition Sub maintained for the Class B Non-Voting
Preference Shares an amount equal to the stated
capital of the Class B Non-Voting Preference Shares,
calculated as set out in section 2.2.2.4, less the
amount previously deducted pursuant to section
2.2.3.5.1; and
2.2.3.5.4.      there will be added to the stated capital
account in the accounting records of Acquisition Sub
maintained for the common shares of Acquisition Sub an
amount equal to the amount deducted pursuant to
section 2.2.3.5.3 from the stated capital account
maintained for the Class B Non-Voting Preference
Shares;
2.2.4.  outstanding ObjecTime Options will be reorganized as
follows:
2.2.4.1.        Rational will assume each of the ObjecTime
Option Plans, which, from and after the Effective Time, will
be deemed to be modified (i) to refer to Rational as the
grantor of the ObjecTime Options and the issuer of the
securities issuable upon exercise of the ObjecTime Options,
(ii) to refer to Rational Common Shares as the securities
issuable upon exercise of the ObjecTime Options and (iii) to
be otherwise subject to the terms of this Plan of
Arrangement;
2.2.4.2.        each outstanding ObjecTime Option will become an
option (an "Assumed Option") to purchase a number of
Rational Common Shares equal to the product of the Exchange
Ratio multiplied by the number of ObjecTime Shares subject
to that ObjecTime Option.  The Assumed Option will provide
for an exercise price per Rational Common Share equal to the
United States Dollar Equivalent of the exercise price per
share of the ObjecTime Option immediately prior to the
Effective Time divided by the Exchange Ratio.  If the
foregoing calculation results in an Assumed Option being
exercisable for a fraction of a Rational Common Share, then
the number of Rational Common Shares subject to that Assumed
Option will be rounded down to the next whole number of
Rational Common Shares and the total exercise price for the
Assumed Option will be reduced by the exercise price of the
fractional Rational Common Share.  The term to expiry,
conditions to and manner of exercising, vesting schedule,
and all other terms and conditions of the Assumed Option
will otherwise be unchanged from those of the ObjecTime
Options except as set out in this Plan of Arrangement, and
any document or agreement previously evidencing a ObjecTime
Option will afterwards evidence and be deemed to evidence
the Assumed Option;
2.2.4.3.        all Assumed Options which have not vested on or
prior to November 30, 1999 and one-third (1/3) of each
holder's Assumed Options which have vested on or prior to
November 30, 1999 may be exercised by the respective holders
as they become vested in accordance with the terms of the
respective ObjecTime Option Plan under which those Assumed
Options were granted, as amended by this Plan of
Arrangement;
2.2.4-4.        two-thirds (2/3) of each holder's Assumed
Options which have vested on or prior to November 30, 1999
(the "Restricted Options") will be deposited with Rational
and distributed to the holder of the Restricted Options or
transferred to Rational as contemplated by the Vesting and
Release Schedule attached to the Escrow Agreement, and, if
and when distributed to the holder, may be exercised by the
holder in accordance with the terms of the respective
ObjecTime Option Plan under which the distributed Restricted
Options were granted, as amended by this Plan of
Arrangement; and
2.2.4.5.        notwithstanding the terms of the respective
ObjecTime Option Plan under which any Restricted Options
were granted, in the event that the employment of a holder
of Restricted Options with New ObjecTime is terminated in a
manner which would not permit a Blockage Notice (as defined
in the Escrow Agreement) to be delivered under the Vesting
and Release Schedule attached to the Escrow Agreement
(including termination without cause, death or disability),
then Rational will continue to distribute those Restricted
Options to the holder of the Restricted Options as
contemplated by the Vesting and Release Schedule and those
Restricted Options may be exercised by the holder in
accordance with section 2.2.4.4 until 30 days after the date
on which all Exchangeable Shares are required to be
exchanged in accordance with their terms;
2.2.5.  coincident with and as part of the capital reorganization
set out in section 2.2.3, Rational and Acquisition Sub will execute
the Voting and Exchange Trust Agreement and Rational will issue to
and deposit with the Trustee the Deposited Shares, certain voting
rights in respect of which Deposited Shares will be granted in
consideration of the payment to Rational of US$1.00, which Deposited
Shares will be afterwards held of record by the Trustee as trustee
solely for the use and benefit of Rational in accordance with the
Voting and Exchange Trust Agreement except with respect to certain
voting rights which the Trustee will hold for and on behalf of, and
for the use and benefit of the holders of the Exchangeable Shares in
accordance with the Voting and Exchange Trust Agreement.  All rights
of holders of Exchangeable Shares under the Voting and Exchange
Trust Agreement will be received by them as part of the property
receivable under section 2.2.3.3 in exchange for the Class B
Non-Voting Preference Shares; and
2.2.6.  immediately after the capital reorganization, each of the
holders of Rational Common Shares and Exchangeable Shares issued
pursuant to this Plan of Arrangement will be deemed to have entered
into and to be bound by the provisions of the Escrow Agreement in
respect of all of those shares issued to the holder.
2.3.    Section 85 Election
Each holder of Class A Preferred Shares and Class 8 Special
Shares will be entitled to make an income tax election pursuant to
section 85 of the Income Tax Act (Canada) and any other similar
provision of provincial law with respect to the conversion of that
holder's Class A Preferred Shares or Class 8 Special Shares, as the case
may be, into Class B Common Shares pursuant to section 2.2.1 of this
Arrangement by providing two signed copies of the necessary election
forms to New ObjecTime within 90 days following the issuance of a
Certificate of Arrangement in respect of the Arrangement, duly completed
with the details of the number of shares converted and the applicable
agreed amounts for the purposes of that election.  Thereafter, subject
to the election forms complying with the provisions of the Income Tax
Act (Canada), the forms will be signed by New ObjecTime and returned to
that ObjecTime Shareholder for filing with Canada Customs and Revenue
Agency within 180 days following the date of issuance of a Certificate
of Arrangement in respect of the Arrangement.
2.4.    Allocation of Proceeds
Each ObjecTime Shareholder who holds shares both directly
and indirectly through a registered retirement savings plan of which
that shareholder is the sole beneficiary will be entitled to direct
Holding ULC and Acquisition Sub to allocate the aggregate cash and share
payments payable under this Plan of Arrangement to the ObjecTime
Shareholder personally and to the ObjecTime Shareholder's registered
retirement savings plan as between them in any manner as the ObjecTime
Shareholder directs; provided that, the aggregate consideration received
by each of them equals the aggregate consideration payable to each of
them under this Plan of Arrangement based on the number of ObjecTime
Shares held by each of them.

ARTICLE 3.
RIGHTS OF DISSENT
3.1.    Rights of Dissent
3.1.1.  Holders of ObjecTime Securities may exercise rights of
dissent with respect to those securities pursuant to and in the
manner set out in Section 185 of the OBCA and this section 3.1 (the
"Dissent Rights") in connection with the Arrangement as the same may
be modified by the Interim Order or the Final Order.
3.1.2.  Holders of ObjecTime Securities who duly exercise the rights
of dissent and who:
3.1.2.1.        are ultimately entitled to be paid fair value
for their ObjecTime Securities will be deemed to have
transferred those ObjecTime Securities to Holding ULC
immediately prior to the Effective Time, to the extent the
fair value of those shares is paid by Holding ULC, and to
ObjecTime immediately prior to the Effective Time, to the
extent the fair value of those shares is paid by ObjecTime,
and, in the case of ObjecTime Securities so transferred to
ObjecTime, those securities will be cancelled as of the
Effective Time; or
3.1.2.2.        are ultimately not entitled, for any reason, to
be paid fair value for their ObjecTime Securities will be
deemed to have participated in the Arrangement on the same
basis as any non-dissenting holder of ObjecTime Securities
and will receive cash and Exchangeable Shares or Rational
Common Shares in exchange for their Class B Non-Voting
Preference Shares received on the Amalgamation on the basis
determined in accordance with section 2.2.3 above or Assumed
Options in exchange for their ObjecTime Options on the basis
determined in accordance with section 2.2.4 above;
but in no case will Rational, Acquisition Sub, Holding ULC,
ObjecTime, New ObjecTime or any other Person be required to
recognize those holders as holders of ObjecTime Shares or ObjecTime
Options after the Effective Time, and the names of those holders of
ObjecTime Shares will be deleted from the register of shareholders
of ObjecTime Shares at the Effective Time and the names of those
holders of ObjecTime Options will be deleted from any register or
record of holders of ObjecTime Options at the Effective Time.

ARTICLE 4.
CERTIFICATES AND FRACTIONAL SHARES
4.1.    Delivery of Register and Certificates
Immediately prior to the Effective Time, ObjecTime will
deliver to Rational a certified copy of the register of ObjecTime
Shareholders, together with all original certificates representing
outstanding ObjecTime Shares.
4.2.    Delivery of Cash
At the Effective Time, Holding ULC will deliver to a
representative of ObjecTime (the "ObjecTime Disbursing Representative")
one or more cheques, issued in those amounts as may be requested by the
ObjecTime Disbursing Representative no less than two Business Days prior
to the Effective Time, which cheque(s) represent in the aggregate the
total amount of cash which all former holders of ObjecTime Shares have
the right to receive in accordance with this Plan of Arrangement
(rounded down, in the case of each holder, to the nearest whole cent).
The ObjecTime Disbursing Representative will deliver to each former
holder of ObjecTime Shares the cash which that holder has a right to
receive in accordance with section 2.2.3.1 and 2.2.3.2.
4.3.    Delivery of Exchangeable Shares
At or promptly after the Effective Time, Acquisition Sub
will deposit with the Depositary, for the benefit of the holders of
Class B Non-Voting Preference Shares who will receive Exchangeable
Shares in connection with the Arrangement, the certificates representing
the Exchangeable Shares issued upon the exchange of Class B Non-Voting
Preference Shares.  The certificates representing the Exchangeable
Shares issued will be held in accordance with the Escrow Agreement.  The
subaccount of each holder maintained in accordance with the Escrow
Agreement will be credited with that number of Exchangeable Shares which
the holder has the right to receive.
4.4.    Delivery of Rational Common Shares
At or promptly after the Effective Time, Holding ULC will
deposit with the Depositary, for the benefit of the holders of Class B
Non-Voting Preference Shares who will receive Rational Common Shares in
connection with the Arrangement, the certificates representing the
Rational Common Shares issued upon the exchange of Class B Non-Voting
Preference Shares.  The certificates representing the Rational Common
Shares issued will be held in accordance with the Escrow Agreement.  The
subaccount of each holder maintained in accordance with the Escrow
Agreement will be credited with that number of Rational Common Shares
which the holder has the right to receive.
4.5.    Class B -on-Voting Preference Shares
For greater certainty, no certificates representing Class B
Non-Voting Preference Shares will be issued and those Class B Non-Voting
Preference Shares will be evidenced by the certificates representing
ObjecTime Shares converted into Class B Non-Voting Preference Shares on
the Amalgamation.
4.6.    Fractional Shares
If as a result of the Amalgamation, a Person will become
entitled to a fractional interest in a Class B Non-Voting Preference
Share, the fractional interest in that Class B Non-Voting Preference
Share will be rounded to the nearest whole Class B Non-Voting Preference
Share and the whole Class B Non-Voting Preference Shares that Person is
entitled to receive on the Amalgamation will be evidenced by the
certificates representing the ObjecTime Shares held by that Person which
were converted into those Class B Non-Voting Preference Shares on the
Amalgamation.
Pursuant to sections 2.2.3.1 and 2.2.3.2, exchanges of
Class B Non-Voting Preference Shares for cash and Rational Common Shares
or Exchangeable Shares will occur only on the basis of whole Class B
Non-Voting Preference Shares.  No certificates or scrip representing
fractional Exchangeable Shares or fractional Rational Common Shares will
be issued to any holder of Class B Non-Voting Preference Shares and no
dividend, stock split or other change in the capital structure of
Acquisition Sub or Rational, as the case may be, will relate to any
fractional security and those fractional interests will not entitle the
owner of those interests to exercise any rights as a security holder of
Acquisition Sub or Rational, as the case may be.
4.7.    Extinction of Rights
Any cheques representing the cash amount payable to a former
holder of ObjecTime Shares in accordance with this Plan of Arrangement
which cheque has not been presented to the bankers of Holding ULC for
payment or that otherwise remain unclaimed for a period of six years
from the date on which they were mailed will be forfeited to Holding
ULC.
4.8.    Withholding Rights
Acquisition Sub, Holding ULC, Rational and the Depositary
will be entitled to deduct and withhold from any dividend or
consideration otherwise payable to any holder of ObjecTime Shares,
Class B Non-Voting Preference Shares, Rational Common Shares or
Exchangeable Shares, any amounts as Acquisition Sub, Holding ULC,
Rational or the Depositary is required or permitted to deduct and
withhold with respect to that payment under the ITA, the United States
Internal Revenue Code of 1986 or any provision of provincial, state,
local or foreign tax Law, in each case, as amended.  To the extent that
amounts are so withheld, those withheld amounts will be treated for all
purposes of this Plan of Arrangement as having been paid to the holder
of the shares in respect of which the deduction and withholding was
made, provided that the withheld amounts are actually remitted to the
appropriate taxing authority.  To the extent that the amount so required
or permitted to be deducted or withheld from any payment to a holder
exceeds the cash portion of the consideration otherwise payable to the
holder, Acquisition Sub, Holding ULC, Rational and the Depositary are
hereby authorized to sell or otherwise dispose of that portion of the
consideration as is necessary to provide sufficient funds to Acquisition
Sub, Holding ULC, Rational or the Depositary, as the case may be, to
enable it to comply with those deduction or withholding requirement and
Acquisition Sub, Holding ULC, Rational or the Depositary will notify the
holder and remit to the holder any unapplied balance of the net proceeds
of that sale.

ARTICLE 5.
CERTAIN RIGHTS OF HOLDING ULC TO ACQUIRE
EXCHANGEABLE SHARES
5.1.    Holding ULC Liquidation Call Right
5.1.1.  Holding ULC will have the overriding right (the "Liquidation
Call Right"), in the event of and notwithstanding the proposed
liquidation, dissolution or winding-up of Acquisition Sub pursuant
to Article 5 of the Exchangeable Share Provisions, to purchase from
all but not less than all of the holders of Exchangeable Shares
(other than any holder of Exchangeable Shares which is an affiliate
of Rational) on the Liquidation Date all but not less than all of
the Exchangeable Shares held by each holder on payment by Holding
ULC of an amount per share (the "Liquidation Call Purchase Price")
equal to the Current Market Price of a Rational Common Share on the
last Business Day prior to the Liquidation Date, which will be
satisfied in full by Holding ULC causing to be delivered to that
holder one Rational Common Share, plus, to the extent not paid by
Acquisition Sub, an additional amount equivalent to the full amount
of all declared and unpaid dividends on each Exchangeable Share held
by that holder on any dividend record date which occurred prior to
the date of purchase by Holding ULC (the "Dividend Amount").  In the
event of the exercise of the Liquidation Call Right by Holding ULC,
each holder will be obligated to sell all of the Exchangeable Shares
held by the holder to Holding ULC on the Liquidation Date on payment
by Holding ULC to the holder of the Liquidation Call Purchase Price
for each share, and Acquisition Sub will have no obligation to pay
the Liquidation Amount of those shares so purchased by Holding ULC.
5.1.2.  To exercise the Liquidation Call Right, Holding ULC must
notify Acquisition Sub's transfer agent (the "Transfer Agent"), as
agent for the holders of Exchangeable Shares, and Acquisition Sub of
Holding ULC's intention to exercise that right at least 45 days
before the Liquidation Date in the case of a voluntary liquidation,
dissolution or winding-up of Acquisition Sub and at least five
Business Days before the Liquidation Date in the case of an
involuntary liquidation, dissolution or winding-up of Acquisition
Sub.  The Transfer Agent will notify the holders of Exchangeable
Shares as to whether or not Holding ULC has exercised the
Liquidation Call Right promptly after the expiry of the period
during which the same may be exercised by Holding ULC.  If Holding
ULC exercises the Liquidation Call Right, then on the Liquidation
Date, Holding ULC will purchase and the holders will sell all of the
Exchangeable Shares then outstanding for a price per share equal to
the Liquidation Call Purchase Price.
5.1.3.  For the purposes of completing the purchase of the
Exchangeable Shares pursuant to the Liquidation Call Right, Holding
ULC will instruct and authorize the Trustee to deposit with the
Transfer Agent, on or before the Liquidation Date, certificates
representing the aggregate number of Rational Common Shares
deliverable by Holding ULC and a cheque or cheques of Holding ULC
payable at par at any branch of the bankers of Holding ULC
representing the aggregate Dividend Amount in payment of the total
Liquidation Call Purchase Price, less any amounts withheld pursuant
to section 4.8 of this Plan of Arrangement.  Provided that Holding
ULC has complied with the immediately preceding sentence, on and
after the Liquidation Date, the rights of each holder of
Exchangeable Shares will be limited to receiving that holder's
proportionate part of the total Liquidation Call Purchase Price
payable by Holding ULC upon presentation and surrender by the holder
of certificates representing the Exchangeable Shares held by that
holder and the holder will on and after the Liquidation Date be
considered and deemed for all purposes to be the holder of the
Rational Common Shares to which it is entitled.  Upon surrender to
the Transfer Agent of a certificate or certificates representing
Exchangeable Shares, together with any other documents and
instruments as may be required to effect a transfer of Exchangeable
Shares under the OBCA and the by-laws of Acquisition Sub and any
additional documents and instruments as the Transfer Agent may
reasonably require, the holder of the surrendered certificate or
certificates will be entitled to receive in exchange for the
certificate(s), and the Transfer Agent on behalf of Holding ULC will
deliver to that holder, certificates representing the Rational
Common Shares to which the holder is entitled and a cheque or
cheques of Holding ULC payable at par at any branch of the bankers
of Holding ULC in payment of the remaining portion, if any, of the
total Liquidation Call Purchase Price, less any amounts withheld
pursuant to section 4.8 of this Plan of Arrangement.  If Holding ULC
does not exercise the Liquidation Call Right in the manner described
above, on the Liquidation Date the holders of the Exchangeable
Shares will be entitled to receive in exchange for those shares the
liquidation price otherwise payable by Acquisition Sub in connection
with the liquidation, dissolution or winding-up of Acquisition Sub
pursuant to Article 5 of the Exchangeable Share Provisions.
5.2.    Holding ULC Redemption Call Right
5.2.1.  Holding ULC will have the overriding right (the "Redemption
Call Right"), notwithstanding the proposed redemption of
Exchangeable Shares by Acquisition Sub pursuant to Article 7 of the
Exchangeable Share Provisions, to purchase from all but not less
than all of the holders of Exchangeable Shares (other than any
holder of Exchangeable Shares which is an affiliate of Rational) on
the Redemption Date all but not less than all of the Exchangeable
Shares held by each holder on payment by Holding ULC to each holder
of an amount per Exchangeable Share (the "Redemption Call Purchase
Price") equal to the Current Market Price of a Rational Common Share
on the last Business Day prior to the Redemption Date, which will be
satisfied in full by Holding ULC causing to be delivered to that
holder one Rational Common Share, plus the Dividend Amount.  In the
event of the exercise of the Redemption Call Right by Holding ULC,
each holder will be obligated to sell all of the Exchangeable Shares
held by the holder to Holding ULC on the Redemption Date on payment
by Holding ULC to the holder of the Redemption Call Purchase Price
for each share, and Acquisition Sub will have no obligation to
redeem those shares so purchased by Holding ULC.
5.2.2.  To exercise the Redemption Call Right, Holding ULC must
notify the Transfer Agent, as agent for the holders of Exchangeable
Shares, and Acquisition Sub of Holding ULC's intention to exercise
that right at least 60 days before the Redemption Date, except in
the case of a redemption occurring as a result of a Rational Control
Transaction, an Exchangeable Share Voting Event or an Exempt
Exchangeable Share Voting Event, in which case Holding ULC will so
notify the Transfer Agent and Acquisition Sub on or before the
Redemption Date.  The Transfer Agent will notify the holders of
Exchangeable Shares as to whether or not Holding ULC has exercised
the Redemption Call Right promptly after the expiry of the period
during which the same may be exercised by Holding ULC.  If Holding
ULC exercises the Redemption Call Right, then on the Redemption
Date, Holding ULC will purchase and the holders will sell all of the
Exchangeable Shares then outstanding for a price per share equal to
the Redemption Call Purchase Price.
5.2.3.  For the purposes of completing the purchase of the
Exchangeable Shares pursuant to the Redemption Call Right, Holding
ULC will instruct and authorize the Trustee to deposit with the
Transfer Agent, on or before the Redemption Date, certificates
representing the aggregate number of Rational Common Shares
deliverable by Holding ULC and a cheque or cheques of Holding ULC
payable at par at any branch of the bankers of Holding ULC
representing the aggregate Dividend Amount in payment of the total
Redemption Call Purchase Price, less any amounts withheld pursuant
to section 4.8 of this Plan of Arrangement.  Provided that Holding
ULC has complied with the immediately preceding sentence, on and
after the Redemption Date, the rights of each holder of Exchangeable
Shares will be limited to receiving that holder's proportionate part
of the total Redemption Call Purchase Price payable by Holding ULC
upon presentation and surrender by the holder of certificates
representing the Exchangeable Shares held by that holder and the
holder will on and after the Redemption Date be considered and
deemed for all purposes to be the holder of the Rational Common
Shares to which it is entitled.  Upon surrender to the Transfer
Agent of a certificate or certificates representing Exchangeable
Shares, together with any other documents and instruments as may be
required to effect a transfer of Exchangeable Shares under the OBCA
and the by-laws of Acquisition Sub and any additional documents and
instruments as the Transfer Agent may reasonably require, the holder
of the surrendered certificate or certificates will be entitled to
receive in exchange for the certificate(s), and the Transfer Agent
on behalf of Holding ULC will deliver to that holder, certificates
representing the Rational Common Shares to which the holder is
entitled and a cheque or cheques of Holding ULC payable at par at
any branch of the bankers of Holding ULC in payment of the remaining
portion, if any, of the total Redemption Call Purchase Price, less
any amounts withheld pursuant to section 4.8 of this Plan of
Arrangement.  If Holding ULC does not exercise the Redemption Call
Right in the manner described above, on the Redemption Date the
holders of the Exchangeable Shares will be entitled to receive in
exchange for the shares the redemption price otherwise payable by
Acquisition Sub in connection with the redemption of the
Exchangeable Shares pursuant to Article 7 of the Exchangeable Share
Provisions.
5.3.    Capital Reorganization of Rational
If at any time there is a capital reorganization of Rational
or a consolidation, merger, arrangement or amalgamation (statutory or
otherwise) of Rational with or into another entity (this type of event
being a "Capital Reorganization"), any holder of Exchangeable Shares
whose Exchangeable Shares have not been exchanged for Rational Common
Shares in accordance with the provisions of this Plan of Arrangement,
the Exchangeable Share Provisions or the Voting and Exchange Trust
Agreement prior to the record date for that Capital Reorganization will
be entitled to receive and will accept, upon any exchange occurring
pursuant to the provisions of this Plan of Arrangement, the Exchangeable
Share Provisions or the Voting and Exchange Trust Agreement at any time
after the record date for the Capital Reorganization, in lieu of the
Rational Common Shares that the holder would otherwise have been
entitled to receive pursuant to those provisions, the number of shares
or other securities of Rational or of the entity resulting, surviving or
continuing from the Capital Reorganization, or other property, that the
holder would have been entitled to receive as a result of the Capital
Reorganization if, on the record date, the holder had been the
registered holder of the number of Rational Common Shares to which the
holder was then entitled upon the exchange of the holder's Exchangeable
Shares into Rational Common Shares in accordance with the provisions of
this Plan of Arrangement, the Exchangeable Share Provisions or the
Voting and Exchange Trust Agreement, subject to adjustment thereafter in
the same manner, as nearly as may be possible, as is provided for in
those provisions; provided that no Capital Reorganization will be
carried into effect unless all necessary steps have been taken so that
each holder of Exchangeable Shares is thereafter entitled to receive,
upon exchange of the holder's Exchangeable Shares pursuant to the
provisions of this Plan of Arrangement, the Exchangeable Share
Provisions or the Voting and Exchange Trust Agreement, that number of
shares or other securities of Rational or of the other entity resulting,
surviving or continuing from the Capital Reorganization, or other
property.
5.4.    Other Change in Rational Common Shares
In the case of any reclassification of, or other change in,
the outstanding Rational Common Shares other than a Capital
Reorganization, changes will be made in the rights attaching to the
Exchangeable Shares, without any action on the part of Acquisition Sub
or the holders of the Exchangeable Shares to the extent permitted by
applicable law, effective immediately following the record date for that
reclassification or other change, to the extent necessary to ensure that
holders of Exchangeable Shares are entitled to receive, upon the
occurrence at any time after that record date of any event whereby they
would receive Rational Common Shares pursuant to the provisions of this
Plan of Arrangement, the Exchangeable Share Provisions or the Voting and
Exchange Trust Agreement, those shares, securities or rights as they
would have received if their Exchangeable Shares had been exchanged for
Rational Common Shares immediately prior to that record date, subject to

board of directors of the Company out of monies of the Company properly
applicable to the payment of dividends, non-cumulative preferential cash
dividends in the amount of 5 cents ($0.05) per preference share per annum.
If in any financial year of the Company the board of directors in their

4. Redemption by Company
 Subject to the provisions of the OBCA, the Company shall be
entitled, upon giving notice as hereinafter provided, at any time from
and after January 21, 2020 to redeem any or all of the preference shares
registered in the name of a holder for an amount per share equal to
(a) U.S.$1.00 per preference share (the "redemption amount") plus (b)
all dividends declared and unpaid thereon to and including the
redemption date (collectively, the "redemption price").
 In case a part only of the preference shares is at any time to be
redeemed, the shares so to be redeemed may be selected by lot in such
manner as the board of directors of the Company in their sole discretion
shall by resolution determine or redemption may be effected on a pro
rata basis disregarding fractions.  If a part only of the preference
shares represented by any certificate shall be redeemed, a new
certificate representing the balance of such shares shall be issued to
the holder thereof at the expense of the Company upon presentation and
surrender of the first-mentioned certificate.
 In any case of redemption of preference shares, the Company shall
at least ten (10) days before the date specified for redemption mail to
each person who at the date of mailing is a registered holder of
preference shares to be redeemed a notice in writing of the intention of
the Company to redeem such preference shares.  Such notice shall set out
the number of preference shares held by the person to whom it is
addressed which are to be redeemed, the redemption price and the date on
which redemption is to take place.  On or after the date so specified
for redemption, the Company shall pay or cause to be paid to or to the
order of the registered holders of the preference shares to be redeemed
the redemption price (less any tax required to be deducted and withheld
therefrom by the Company) of such shares on presentation and surrender,
at the registered office of the Company or at any other place or places
within Canada as may be specified in such notice, of the certificate(s)
representing the preference shares so called for redemption with such
other documents and instruments as may be required to effect a transfer
of preference shares under the OBCA and the by-laws of the Company and
such additional documents and instruments as the Company may reasonably
require.  Payment of the total redemption price for such preference
shares shall be made by delivery to each holder, at the address of the
holder recorded in the securities register of the Company or by holding
for pick up by the holder at the registered office of the Company of a
cheque of the Company in respect of the redemption price (less any tax
required to be deducted and withheld therefrom by the Company) payable
at par at any branch in Canada of the bankers of the Company for the
time being.  From and after the date specified for redemption in any
such notice, the preference shares called for redemption shall cease to
be entitled to dividends or any other participation in the property or
assets of the Company and the holders thereof shall not be entitled to
exercise any of the other rights of shareholders in respect thereof
unless payment of the redemption price shall not be made upon
presentation and surrender of the certificate(s) in accordance with the
foregoing provisions, in which case the rights of the holders shall
remain unaffected.
 The Company shall have the right at any time after the mailing of
notice of its intention to redeem the preference shares to deposit the
redemption price of the preference shares so called for redemption or of
such of the said shares represented by certificate(s) which have not at
the date of such deposit been surrendered by the holders thereof in
connection with such redemption to a special account in any chartered
bank or any trust company in Canada named in such notice, to be paid
without interest to or to the order of the respective holders of
preference shares called for redemption upon presentation and surrender
to such bank or trust company of the certificate(s) representing such
shares.  Upon such deposit being made or upon the date specified for
redemption in such notice, whichever is the later, the preference shares
in respect of which such deposit shall have been made shall be deemed to
be redeemed and the rights of the holders thereof shall be limited to
receiving without interest their proportionate part of the amount so
deposited upon presentation and surrender of the certificate(s) held by
them respectively.  Any interest allowed on any such deposit shall
belong to the Company.
 Redemption monies which are represented by a cheque which has not
been presented to the Company's bankers for payment or that otherwise
remain unclaimed (including monies held on deposit in a special account
as provided for above) for a period of six years from the date specified
for redemption shall be forfeited to the Company.
5. Liquidation, Dissolution or Winding Up
 In the event of the liquidation, dissolution or winding up of the
Company, or any other distribution of property or assets of the Company
among its shareholders for the purpose of winding up its affairs, and
after payment to the holders of the shares of any class or series of
shares in the capital of the Company ranking senior to the preference
shares of amounts they are entitled to, the holders of the preference
shares shall be entitled to receive from the property and assets of the
Company a sum equal to the redemption amount of the preference shares
held by them respectively plus all dividends declared and unpaid thereon
to and including the date of payment and no more, in priority to the
rights of the holders of the common shares and the shares of any other
class or series of shares in the capital of the Company ranking junior
to the preference shares.  After payment to the holders of the
preference shares of the amounts so payable to them, they shall not be
entitled to share in any further distribution of the property or assets
of the Company.
6. Notices
Any notice, cheque, notice of redemption or other communication
from the Company herein provided for shall be either sent to the holders
of the preference shares by ordinary unregistered mail, postage prepaid,
or delivered by hand to such holders, at their respective addresses
appearing on the securities register of the Company or, in the event of
the address of any such holder not so appearing, then at the last
address known to the Company of such holder.  Accidental failure to give
any such notice, notice of redemption or other communication to one or
more holders of preference shares shall not affect the validity thereof,
but, upon such failure being discovered, a copy of the notice, notice of
redemption or other communication, as the case may be, shall be sent or
delivered forthwith to such holder or holders.  Unless otherwise
provided herein, any notice, certificate or other communication from a
holder of preference shares herein provided for shall be either sent to
the Company by ordinary unregistered mail, postage prepaid, or delivered
by hand to the Company, at its registered office.  Any notice or other
communication, including without limitation a notice of redemption or
request for redemption, from the Company to the holders of the
preference shares or from a holder of preference shares to the Company
may be waived.

excess of the Preferential Dividend Amount and will rank senior to the

The holders of the Class B non-voting preference shares will
not be entitled to receive notice of or to attend or to vote at any
meeting of shareholders of the Company and will not be entitled to vote
separately as a class upon any proposal to amend the articles of the
Company to change the maximum number of the shares of any class of
shares or series of shares, or to effect an exchange, reclassification
or cancellation of the Class B non-voting preference shares, or to
create a new class of shares or series of shares having rights or
privileges equal or superior to the Class B non-voting preference
shares, provided, however, that notwithstanding the foregoing provisions
of this section 2, the holders of the Class B non-voting preference
shares will be entitled to vote separately as a class in respect of any
matter for which a separate vote is specifically provided in the
Business Corporations Act (Ontario) or any successor statute, other than
in respect of a proposal to amend the articles in a manner set out above
in this section 2.
3.      Dividends
Subject always to the prior rights of the holders of the
Exchangeable Shares, the Class C Shares and of any shares of any other
class or series ranking senior to the Class B non-voting preference
shares, the holders of the Class B non-voting preference shares will be
entitled, prior to the payment of any dividends to the holders of common
shares in any financial year of the Company, to receive in each
financial year of the Company, if, as and when declared by the board of
directors of the Company out of monies of the Company properly
applicable to the payment of dividends, non-cumulative preferential cash
dividends in the amount of 8% of the Liquidation Amount (as defined
below) per Class B non-voting preference share per annum (the
"Preferential Dividend Amount").  If, in any financial year of the
Company, the board of directors in their discretion do not declare the
Preferential Dividend Amount or any part of the Preferential Dividend
Amount on the Class B non-voting preference shares then the right of the
holders of the Class B non-voting preference shares to the Preferential
Dividend Amount or any greater preferential dividends than the
preferential dividends actually declared for that financial year will be
forever extinguished.
After payment of the Preferential Dividend Amount in respect
of each Class B non-voting preference share for a particular financial
year of the Company, the holders of the Class B non-voting preference
shares and common shares will participate equally as to any additional
dividends, if, as and when declared by the board of directors of the
Company and all additional dividends which the directors may determine
to declare and pay in any financial year of the Company will be declared
and paid in equal or equivalent amounts per share, out of money, assets
or property of the Company properly applicable to the payment of
dividends or out of authorized but unissued shares of the Company, as
applicable, on all the Class B non-voting preference shares and common
shares at the time outstanding without preference or distinction.
4.      Liquidation, Dissolution or Winding-Up
In the event of the liquidation, dissolution or winding up
of the Company, or any other distribution of the assets of the Company
among its shareholders for the purpose of winding up its affairs, and
after payment to the holders of the Exchangeable Shares, the Class C
Shares and the shares of any other class or series of shares in the
capital of the Company ranking senior to the Class B non-voting
preference shares of amounts they are entitled to, the holders of the
Class B non-voting preference shares will be entitled to receive from
the property and assets of the Company a sum equal to the Liquidation
Amount (as defined below) of each Class B non-voting preference share
held by them respectively plus all dividends declared and unpaid on the
Class B non-voting preference shares to and including the date of
payment and no more, in priority to the rights of the holders of the
common shares and the shares of any other class or series of shares in
the capital of the Company ranking junior to the Class B non-voting
preference shares.  The "Liquidation Amount" of a Class B non-voting
preference share is equal to the quotient obtained by dividing:
(a) US$38,700,000 by
(b) the number of issued and outstanding Class B non-voting
preference shares as of the date on which entitlements to
the Liquidation Amount are fixed.
After payment to the holders of the Class B non-voting
preference shares of the Liquidation Amounts so payable to them, they
will not be entitled to share in any further distribution of the
property or assets of the Company.
5.      Notices
Any notice, cheque or other communication from the Company
provided for in these share provisions will be sent to the holders of

respective addresses appearing on the securities register of the Company
or, in the event of the address of any holder not so appearing, then at
the last address of that holder known to the Company.  Accidental
failure to give any notice or other communication to one or more holders
of Class B non-voting preference shares will not affect the validity of
the notice, but, upon the failure being discovered, a copy of the notice
or other communication will be sent or delivered promptly to the holder
or holders.  Any notice or other communication from the Company to the
holders of the Class B non-voting preference shares may be waived.

1.2     Unless otherwise indicated, references to "Article", "Articles",
"section" and "sections" are to articles and sections in these
share provisions.
ARTICLE 2
RANKING OF EXCHANGEABLE SHARES
2.1     The Exchangeable Shares will be entitled to a preference over
the Common Shares, the Preference Shares and any other shares
ranking junior to the Exchangeable Shares with respect to the
payment of dividends and the distribution of assets in the
event of the liquidation, dissolution or winding-up of the
Company, whether voluntary or involuntary, or any other
distribution of the assets of the Company among its
shareholders for the purpose of winding up its affairs.
ARTICLE 3.
DIVIDENDS
3.1     Subject to section 3.2, a holder of an Exchangeable Share
will be entitled to receive and the Board of Directors will,
subject to applicable law, on each Rational Dividend
Declaration Date, declare a dividend on each Exchangeable
Share:
(a) in the case of a cash dividend declared on the Rational
Common Shares, in an amount in cash for each Exchangeable
Share in U.S. dollars, or the Canadian Dollar Equivalent on
the Rational Dividend Declaration Date, in each case,
corresponding to the cash dividend declared on each Rational
Common Share;
(b) in the case of a stock dividend declared on the Rational
Common Shares to be paid in Rational Common Shares, in that
number of Exchangeable Shares for each Exchangeable Share as
is equal to the number of Rational Common Shares to be paid
on each Rational Common Share; or
(c) in the case of a dividend declared on the Rational Common
Shares in property other than cash or Rational Common Shares,
in that type and amount of property for each Exchangeable
Share as is the same as or economically equivalent to (to be
determined by the Board of Directors as contemplated by
section 3.5) the type and amount of property declared as a
dividend on each Rational Common Share.
These dividends will be paid out of money, assets or property of the
Company properly applicable to the payment of dividends, or out of
authorized but unissued shares of the Company, as applicable.
3.2     In the case of a stock dividend declared on the Rational
Common Shares to be paid in Rational Common Shares, in lieu
of declaring the stock dividend contemplated by
section 3.1(b) on the Exchangeable Shares, the Board of
Directors may, in its discretion and subject to applicable
law, subdivide, redivide or change (the "subdivision") each
issued and unissued Exchangeable Share on the basis that
each Exchangeable Share before the subdivision becomes a
number of Exchangeable Shares as is equal to the sum of (i)
one Rational Common Share and (ii) the number of Rational
Common Shares to be paid as a stock dividend on each
Rational Common Share.  In that instance, and
notwithstanding any other provision, the subdivision will
become effective on the effective date specified in
section 3.4 without any further act or formality on the part
of the Board of Directors or of the holders of Exchangeable
Shares.  For greater certainty, no approval of the holders
of Exchangeable Shares to an amendment to the articles of
the Company will be required to give effect to the
subdivision.
3.3     Cheques of the Company payable at par at any branch of the
bankers of the Company will be issued in respect of any cash
dividends contemplated by section 3.1(a) and the sending of
a cheque to each holder of an Exchangeable Share will
satisfy the cash dividend represented by that cheque unless
the cheque is not paid on presentation. Subject to
applicable law, certificates registered in the name of the
registered holder of Exchangeable Shares will be issued or
transferred in respect of any stock dividends contemplated
by section 3.1(b) or any subdivision of shares contemplated
by section 3.2 and the sending of that certificate to each
holder of an Exchangeable Share will satisfy the stock
dividend or share subdivision represented by that
certificate.  Any other type and amount of property in
respect of any dividends contemplated by section 3.1(c) will
be issued, distributed or transferred by the Company in any
manner as it determines and the issuance, distribution or
transfer of that property by the Company to each holder of
an Exchangeable Share will satisfy the dividend represented
by the issuance, distribution or transfer of that property.
No holder of an Exchangeable Share will be entitled to
recover by action or other legal process against the Company
any dividend that is represented by a cheque that has not
been duly presented to the Company's bankers for payment or
that otherwise remains unclaimed for a period of six years
from the date on which the dividend was payable.
3.4     The record date for the determination of the holders of
Exchangeable Shares entitled to receive payment of, and the
payment date for, any dividend declared on the Exchangeable
Shares under section 3.1 will be the same dates as the
record date and payment date, respectively, for the
corresponding dividend declared on the Rational Common
Shares.  The record date for the determination of the
holders of Exchangeable Shares entitled to receive
Exchangeable Shares in connection with any subdivision of
Exchangeable Shares under section 3.2 and the effective date
of that subdivision will be the same dates as the record
date and payment date, respectively, for the corresponding
stock dividend declared on Rational Common Shares.
3.5     If on any payment date for any dividends declared on the
Exchangeable Shares under section 3.1 the dividends are not
paid in full on all of the Exchangeable Shares then
outstanding, any dividends that remain unpaid will be paid
on a subsequent date or dates determined by the Board of
Directors on which the Company has sufficient moneys, assets
or property properly applicable to the payment of those
dividends.
3.6     The Board of Directors will determine, in good faith and in
its sole discretion, economic equivalence for the purposes
of sections 3.1 and 3.2, and each determination will be
conclusive and binding on the Company and its shareholders.
In making each determination, the following factors will,
without excluding other factors determined by the Board of
Directors to be relevant, be considered by the Board of
Directors:
(a) in the case of any stock dividend or other distribution
payable in Rational Common Shares, the number of those shares
issued in proportion to the number of Rational Common Shares
previously outstanding;
(b) in the case of the issuance or distribution of any rights,
options or warrants to subscribe for or purchase Rational
Common Shares (or securities exchangeable for or convertible
into or carrying rights to acquire Rational Common Shares),
the relationship between the exercise price of each right,
option or warrant and the current market value (as determined
by the Board of Directors in the manner contemplated above)
of a Rational Common Share;
(c) in the case of the issuance or distribution of any other form
of property (including without limitation any shares or
securities of Rational of any class other than Rational
Common Shares, any rights, options or warrants other than
those referred to in section 3.6(b), any evidences of
indebtedness of Rational or any assets of Rational), the
relationship between the fair market value (as determined by
the Board of Directors in the manner contemplated above) of
the property to be issued or distributed with respect to each
outstanding Rational Common Share and the current market
value (as determined by the Board of Directors in the manner
contemplated above) of a Rational Common Share; and
(d) in all cases, the general taxation consequences of the
relevant event to holders of Exchangeable Shares to the
extent that those consequences may differ from the taxation
consequences to holders of Rational Common Shares as a result
of differences between taxation laws of Canada and the United
States (except for any differing consequences arising as a
result of differing marginal taxation rates and without
regard to the individual circumstances of holders of
Exchangeable Shares).
For purposes of the foregoing determinations, the current
market value of any security listed and traded or quoted on a securities
exchange will be the average of the closing bid and ask prices of that
security during a period of not less than 20 consecutive trading days
ending not more than three trading days before the date of determination
on the principal securities exchange on which those securities are
listed and traded or quoted; provided, however, that if in the opinion
of the Board of Directors the public distribution or trading activity of
those securities during that period does not create a market which
reflects the fair market value of those securities, then the current
market value will be determined by the Board of Directors, in good faith
and in its sole discretion, and provided further that any determination
by the Board of Directors will be conclusive and binding on the Company
and its shareholders.
ARTICLE 4.
CERTAIN RESTRICTIONS
4.1     So long as any of the Exchangeable Shares are outstanding,
the Company will not at any time without, but, subject to
section 3.2, may at any time with, the approval of the
holders of the Exchangeable Shares given as specified in
section 11.2:
(a) pay any dividends on the Common Shares, the Preference Shares
or any other shares ranking junior to the Exchangeable
Shares, other than stock dividends payable in Common Shares
or any other shares ranking junior to the Exchangeable
Shares, as the case may be;
(b) redeem or purchase or make any capital distribution in
respect of the Common Shares, the Preference Shares or any
other shares ranking junior to the Exchangeable Shares;
(c) redeem or purchase any other shares of the Company ranking
equally with the Exchangeable Shares with respect to the
payment of dividends or on any liquidation distribution;
(d) issue any Exchangeable Shares other than by way of stock
dividend to the holders of Exchangeable Shares contemplated
by section 3.1 or by way of any subdivision of Exchangeable
Shares contemplated by section 3.2; or
(e) issue any shares of the Company ranking equally with, or
superior to, the Exchangeable Shares other than by way of
stock dividends to the holders of Exchangeable Shares.
The restrictions in sections 4.1(a), 4.1(b), 4.1(c) and
4.1.(d) will not apply if all dividends on the outstanding Exchangeable
Shares corresponding to dividends declared and paid to date on the
Rational Common Shares have been declared and paid on the Exchangeable
Shares.
ARTICLE 5.
DISTRIBUTION ON LIQUIDATION
5.1     In the event of the liquidation, dissolution or winding-up
of the Company or any other distribution of the assets of
the Company among its shareholders for the purpose of
winding up its affairs, subject to the exercise by Holding
ULC of the Liquidation Call Right, a holder of Exchangeable
Shares will be entitled, subject to applicable law, to
receive from the assets of the Company in respect of each
Exchangeable Share held by the holder on the effective date
(the "Liquidation Date") of the liquidation, dissolution or
winding-up, before any distribution of any part of the
assets of the Company among the holders of the Common
Shares, the Preference Shares or any other shares ranking
junior to the Exchangeable Shares, an amount per share equal
to the Current Market Price of a Rational Common Share on
the last Business Day prior to the Liquidation Date (the
"Liquidation Amount"), which will be satisfied in full by
the Company causing to be delivered to the holder one
Rational Common Share, together with all declared and unpaid
dividends on each Exchangeable Share held by the holder on
any dividend record date which occurred prior to the
Liquidation Date.
5.2     On or promptly after the Liquidation Date, the Company will
cause to be delivered to the holders of the Exchangeable
Shares the Liquidation Amount for each Exchangeable Share
upon presentation and surrender of the certificates
representing those Exchangeable Shares, together with any
other documents and instruments as may be required to effect
a transfer of Exchangeable Shares under the Act and the by-
laws of the Company and any additional documents and
instruments as the Transfer Agent, Rational or the Company
may reasonably require, at the registered office of the
Company or at any office of the Transfer Agent as may be
specified by the Company by notice to the holders of the
Exchangeable Shares.  Payment of the total Liquidation
Amount for each Exchangeable Share will be made by delivery
to each holder, at the address of the holder recorded in the
securities register of the Company for the Exchangeable
Shares or by holding for pick-up by the holder at the
registered office of the Company or at any office of the
Transfer Agent as may be specified by the Company by notice
to the holders of Exchangeable Shares, on behalf of the
Company of certificates representing Rational Common Shares
(which shares will be duly issued as fully paid and non-
assessable and will be free and clear of any lien, claim or
encumbrance) and a cheque of the Company payable at par at
any branch of the bankers of the Company in respect of the
remaining portion, if any, of the total Liquidation Amount
(in each case less any amounts withheld on account of tax
required to be deducted and withheld) (without interest). On
and after the Liquidation Date, the holders of the
Exchangeable Shares will cease to be holders of Exchangeable
Shares and will not be entitled to exercise any of the
rights of holders in respect of Exchangeable Shares, other
than the right to receive their proportionate part of the
total Liquidation Amount, unless payment of the total
Liquidation Amount for those Exchangeable Shares is not made
upon presentation and surrender of share certificates in
accordance with the foregoing provisions, in which case the
rights of the holders will remain unaffected until the total
Liquidation Amount has been paid in the manner provided
above. The Company has the right at any time after the
Liquidation Date to deposit or cause to be deposited the
total Liquidation Amount in respect of the Exchangeable
Shares represented by certificates that have not at the
Liquidation Date been surrendered by the holders in a
custodial account with any chartered bank or trust company
in Canada. Upon that deposit being made, the rights of the
holders of Exchangeable Shares after that deposit will be
limited to receiving their proportionate part of the total
Liquidation Amount (in each case less any amounts withheld
on account of tax required to be deducted and withheld)
(without interest) for those Exchangeable Shares so
deposited, against presentation and surrender of the
certificates held by them, respectively, in accordance with
the foregoing provisions. Upon that payment or deposit of
the total Liquidation Amount, the holders of the
Exchangeable Shares will thereafter be considered and deemed
for all purposes to be holders of the Rational Common Shares
delivered to them or the custodian on their behalf.
5.3     After the Company has satisfied its obligations to pay the
holders of the Exchangeable Shares the Liquidation Amount
per Exchangeable Share pursuant to section 5.1, those
holders will not be entitled to share in any further
distribution of the assets of the Company.
ARTICLE 6.
RETRACTION OF EXCHANGEABLE SHARES BY HOLDER
6.1     A holder of Exchangeable Shares will be entitled at any
time, subject to the exercise by Holding ULC of the
Retraction Call Right and otherwise upon compliance with the
provisions of this Article 6, to require the Company to
redeem any or all of the Exchangeable Shares registered in
the name of that holder for an amount per share equal to the
Current Market Price of a Rational Common Share on the last
Business Day prior to the Retraction Date (the "Retraction
Price"), which will be satisfied in full by the Company
causing to be delivered to that holder one Rational Common
Share for each Exchangeable Share presented and surrendered
by the holder, together with, on the payment date, the full
amount of all declared and unpaid dividends on any
Exchangeable Share held by that holder on any dividend
record date which occurred prior to the Retraction Date. To
effect a redemption, the holder will present and surrender
at the registered office of the Company or at any office of
the Transfer Agent as may be specified by the Company by
notice to the holders of Exchangeable Shares the certificate
or certificates representing the Exchangeable Shares which
the holder desires to have the Company redeem, together with
any other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the Act and
the by-laws of the Company and any additional documents and
instruments as the Transfer Agent, Rational or the Company
may reasonably require, together with a duly executed
statement (the "Retraction Request") in the form of
Schedule A to these provisions or in any other form as may
be acceptable to the Company:
(a) specifying that the holder desires to have all or any number
specified of the Exchangeable Shares represented by the
certificate or certificates (the "Retracted Shares") redeemed
by the Company;
(b) stating the Business Day on which the holder desires to have
the Company redeem the Retracted Shares (the "Retraction
Date"), provided that the Retraction Date will be not less
than 10 Business Days nor more than 15 Business Days after
the date on which the Retraction Request is received by the
Company and further provided that, in the event that no
Retraction Date is specified by the holder in the Retraction
Request, the Retraction Date will be deemed to be the 15th
Business Day after the date on which the Retraction Request
is received by the Company; and
(c) acknowledging the overriding right (the "Retraction Call
Right") of Holding ULC to purchase all but not less than all
of the Retracted Shares directly from the holder and that the
Retraction Request will be deemed to be a revocable offer by
the holder to sell the Retracted Shares to Holding ULC in
accordance with the Retraction Call Right on the terms and
conditions set out in section 6.3.
6.2.    Subject to the exercise by Holding ULC of the Retraction
Call Right, upon receipt by the Company or the Transfer
Agent in the manner specified in section 6.1 of a
certificate or certificates representing the number of
Exchangeable Shares which the holder desires to have the
Company redeem, together with a Retraction Request, and
provided that the Retraction Request is not revoked by the
holder in the manner specified in section 6.7, the Company
will redeem the Retracted Shares effective at the close of
business on the Retraction Date and will cause to be
delivered to that holder the total Retraction Price with
respect to those shares, provided that all declared and
unpaid dividends for which the record date has occurred
prior to the Retraction Date will be paid on the payment
date for those dividends. If only a part of the Exchangeable
Shares represented by any certificate is redeemed (or
purchased by Holding ULC pursuant to the Retraction Call
Right), a new certificate for the balance of those
Exchangeable Shares will be issued to the holder at the
expense of the Company.
6.3     Upon receipt by the Company of a Retraction Request, the
Company will immediately notify Holding ULC of the
Retraction Request.  To exercise the Retraction Call Right,
Holding ULC must notify the Company of its determination to
do so (the "Rational Call Notice") within five Business Days
of notification to Holding ULC by the Company of the receipt
by the Company of the Retraction Request. If Holding ULC
does not so notify the Company within the five Business Day
period, the Company will notify the holder as soon as
possible thereafter that Holding ULC will not exercise the
Retraction Call Right. If Holding ULC delivers the Rational
Call Notice within the five Business Day period, and
provided that the Retraction Request is not revoked by the
holder in the manner specified in section 6.7, the
Retraction Request will then be considered only to be an
offer by the holder to sell the Retracted Shares to Holding
ULC in accordance with the Retraction Call Right. In that
event, the Company will not redeem the Retracted Shares and
Holding ULC will purchase from the holder and the holder
will sell to Holding ULC on the Retraction Date the
Retracted Shares for a purchase price (the "Purchase Price")
per share equal to the Retraction Price per share, plus, on
the designated payment date, to the extent not paid by the
Company on the designated payment date, an additional amount
equivalent to the full amount of all declared and unpaid
dividends on those Retracted Shares held by the holder on
any dividend record date which occurred prior to the
Retraction Date (the "Dividend Amount"). For the purposes of
completing a purchase pursuant to the Retraction Call Right,
Holding ULC will deposit with the Transfer Agent, on or
before the Retraction Date, certificates representing
Rational Common Shares and a cheque or cheques of Holding
ULC payable at par at any branch of the bankers of Holding
ULC representing the aggregate Dividend Amount, less any
amounts withheld on account of tax required to be deducted
and withheld (without interest). Provided that Holding ULC
has complied with the immediately preceding sentence, the
closing of the purchase and sale of the Retracted Shares
pursuant to the Retraction Call Right will be deemed to have
occurred as at the close of business on the Retraction Date
and, for greater certainty, no redemption by the Company of
those Retracted Shares will take place on the Retraction
Date. In the event that Holding ULC does not deliver a
Rational Call Notice within the five Business Day period,
and provided that the Retraction Request is not revoked by
the holder in the manner specified in section 6.7, the
Company will redeem the Retracted Shares on the Retraction
Date and in the manner otherwise contemplated in this
Article 6.
6.4     The Company or Holding ULC, as the case may be, will deliver
or cause the Transfer Agent to deliver to the relevant
holder, at the address of the holder recorded in the
securities register of the Company for the Exchangeable
Shares or at the address specified in the holder's
Retraction Request or by holding for pick-up by the holder
at the registered office of the Company or at any office of
the Transfer Agent as may be specified by the Company by
notice to the holders of Exchangeable Shares, certificates
representing the Rational Common Shares (which shares will
be duly issued as fully paid and non-assessable and will be
free and clear of any lien, claim or encumbrance) registered
in the name of the holder or in any other name as the holder
may request, and, if applicable and on or before the payment
date, a cheque payable at par at any branch of the bankers
of the Company or Holding ULC, as applicable, representing
the aggregate Dividend Amount in payment of the total
Retraction Price or the total Purchase Price, as the case
may be, in each case, less any amounts withheld on account
of tax required to be deducted and withheld (without
interest).  The delivery of those certificates and cheques
on behalf of the Company or by Holding ULC, as the case may
be, or by the Transfer Agent will be deemed to be payment of
and will satisfy and discharge all liability for the total
Retraction Price or total Purchase Price, as the case may
be, to the extent that the same is represented by those
share certificates and cheques (plus any tax deducted and
withheld and remitted to the proper tax authority).
6.5     On and after the close of business on the Retraction Date,
the holder of the Retracted Shares will cease to be a holder
of those Retracted Shares and will not be entitled to
exercise any of the rights of a holder in respect of those
Retracted Shares, other than the right to receive the total
Retraction Price or total Purchase Price for the Retracted
Shares, as the case may be, unless upon presentation and
surrender of certificates in accordance with the foregoing
provisions, payment of the total Retraction Price or the
total Purchase Price, as the case may be, is not made as
provided in section 6.4, in which case the rights of that
holder will remain unaffected until the total Retraction
Price or the total Purchase Price, as the case may be, has
been paid in the manner provided above. On and after the
close of business on the Retraction Date, provided that
presentation and surrender of certificates and payment of
the total Retraction Price or the total Purchase Price, as
the case may be, has been made in accordance with the
foregoing provisions, the holder of the Retracted Shares so
redeemed by the Company or purchased by Holding ULC will
thereafter be considered and deemed for all purposes to be a
holder of the Rational Common Shares delivered to that
holder.
6.6     Notwithstanding any other provision of this Article 6, the
Company will not be obligated to redeem Retracted Shares
specified by a holder in a Retraction Request to the extent
that redemption of Retracted Shares would be contrary to
solvency requirements or other provisions of applicable law.
If the Company believes that on any Retraction Date it would
not be permitted by any of those requirements and provisions
to redeem the Retracted Shares tendered for redemption on
that date, and provided that Holding ULC has not exercised
the Retraction Call Right with respect to the Retracted
Shares, the Company will only be obligated to redeem
Retracted Shares specified by a holder in a Retraction
Request to the extent of the maximum number that may be so
redeemed (rounded down to a whole number of shares) as would
not be contrary to those requirements and provisions and
will notify the holder at least two Business Days prior to
the Retraction Date as to the number of Retracted Shares
which will not be redeemed by the Company. In any case in
which the redemption by the Company of Retracted Shares
would be contrary to solvency requirements or other
provisions of applicable law, the Company will redeem the
maximum number of Exchangeable Shares which the Board of
Directors determine the Company is, on the Retraction Date,
permitted to redeem, which will be selected as nearly as may
be pro rata (disregarding fractions) in proportion to the
total number of Exchangeable Shares tendered for retraction
by each holder, and the Company will issue to each holder of
Retracted Shares a new certificate, at the expense of the
Company, representing the Retracted Shares not redeemed by
the Company pursuant to section 6.2.  Provided that the
Retraction Request is not revoked by the holder in the
manner specified in section 6.7 and provided further that
Holding ULC has not exercised the Retraction Call Right with
respect to the Retracted Shares, the holder of any Retracted
Shares not redeemed by the Company pursuant to section 6.2
as a result of solvency requirements or other provisions of
applicable law will be deemed by giving the Retraction
Request to have instructed the Trustee to require Rational
to purchase those Retracted Shares from that holder on the
Retraction Date or as soon as practicable thereafter on
payment by Rational to that holder of the Purchase Price for
the Retracted Shares, all as more specifically provided in
the Voting and Exchange Trust Agreement.
6.7     A holder of Retracted Shares may, by notice in writing given
by the holder to the Company before the close of business on
the Business Day immediately preceding the Retraction Date,
withdraw its Retraction Request, in which case that
Retraction Request will be null and void and, for greater
certainty, the revocable offer constituted by the Retraction
Request to sell the Retracted Shares to Holding ULC will be
deemed to have been revoked.
ARTICLE 7.
REDEMPTION OF EXCHANGEABLE SHARES BY THE COMPANY
7.1.    Subject to applicable law, and provided Holding ULC has not
exercised the Redemption Call Right, the Company will on the
Redemption Date redeem all but not less than all of the then
outstanding Exchangeable Shares for an amount per share
equal to the Current Market Price of a Rational Common Share
on the last Business Day prior to the Redemption Date (the
"Redemption Price"), which will be satisfied in full by the
Company causing to be delivered to each holder of
Exchangeable Shares one Rational Common Share for each
Exchangeable Share held by that holder, together with the
full amount of all declared and unpaid dividends on each
Exchangeable Share held by that holder on any dividend
record date which occurred prior to the Redemption Date (the
"Dividend Amount").
7.2.    In any case of a redemption of Exchangeable Shares under
this Article 7, the Company will, at least 60 days before
the Redemption Date (other than a Redemption Date
established in connection with a Rational Control
Transaction, an Exchangeable Share Voting Event or an Exempt
Exchangeable Share Voting Event), send or cause to be sent
to each holder of Exchangeable Shares a notice in writing of
the redemption by the Company or the purchase by Holding ULC
under the Redemption Call Right, as the case may be, of the
Exchangeable Shares held by that holder. In the case of a
Redemption Date established in connection with a Rational
Control Transaction, an Exchangeable Share Voting Event and
an Exempt Exchangeable Share Voting Event, the written
notice of redemption by the Company or the purchase by
Holding ULC under the Redemption Call Right will be sent on
or before the Redemption Date, on as many days prior written
notice as may be determined by the Board of Directors of the
Company to be reasonably practicable in the circumstances.
In any case, the notice will set out the Redemption Price or
the Redemption Call Purchase Price, as the case may be, the
Redemption Date and, if applicable, particulars of the
Redemption Call Right.
7.3.    On or after the Redemption Date and subject to the exercise
by Holding ULC of the Redemption Call Right, the Company
will cause to be delivered to each holder of the
Exchangeable Shares to be redeemed the Redemption Price for
each Exchangeable Share, together with the full amount of
all declared and unpaid dividends on each Exchangeable Share
held by that holder on any dividend record date which
occurred prior to the Redemption Date, upon presentation and
surrender at the registered office of the Company or at any
office of the Transfer Agent as may be specified by the
Company in the notice of the certificates representing those
Exchangeable Shares, together with any other documents and
instruments as may be required to effect a transfer of
Exchangeable Shares under the Act and the by-laws of the
Company and any additional documents and instruments as the
Transfer Agent, Rational or the Company may reasonably
require. Payment of the total Redemption Price for the
Exchangeable Shares, together with payment of any dividends,
will be made by delivery to each holder, at the address of
the holder recorded in the securities register of the
Company or by holding for pick-up by the holder at the
registered office of the Company or at any office of the
Transfer Agent as may be specified by the Company in the
notice, on behalf of the Company of certificates
representing Rational Common Shares (which shares will be
duly issued as fully paid and non-assessable and will be
free and clear of any lien, claim or encumbrance) and, if
applicable, a cheque of the Company payable at par at any
branch of the bankers of the Company in payment of any
dividends, in each case, less any amounts withheld on
account of tax required to be deducted and withheld (without
interest).  On and after the Redemption Date, the holders of
the Exchangeable Shares called for redemption will cease to
be holders of those Exchangeable Shares and will not be
entitled to exercise any of the rights of holders in respect
of those Exchangeable Shares, other than the right to
receive their proportionate part of the total Redemption
Price and any dividends, unless payment of the total
Redemption Price and any dividends for those Exchangeable
Shares is not made upon presentation and surrender of
certificates in accordance with the foregoing provisions, in
which case the rights of the holders will remain unaffected
until the total Redemption Price and any dividends have been
paid in the manner provided above. The Company has the right
at any time after the sending of notice of its intention to
redeem the Exchangeable Shares to deposit or cause to be
deposited the total Redemption Price for, and the full
amount of dividends on (except as provided in the preceding
sentence), the Exchangeable Shares so called for redemption,
or of those of the Exchangeable Shares represented by
certificates that have not at the date of the deposit been
surrendered by the holders in connection with the
redemption, in a custodial account with any chartered bank
or trust company in Canada named in the notice, less any
amounts withheld on account of tax required to be deducted
and withheld (without interest). Upon the later of any
deposit being made and the Redemption Date, the Exchangeable
Shares in respect of which the deposit has been made will be
redeemed and the rights of the holders after the deposit or
Redemption Date, as the case may be, will be limited to
receiving their proportionate part of the total Redemption
Price and the dividends for those Exchangeable Shares so
deposited (without interest), against presentation and
surrender of the certificates held by them, respectively, in
accordance with the foregoing provisions. Upon payment or
deposit of the total Redemption Price and the full amount of
the dividends, the holders of the Exchangeable Shares will
thereafter be considered and deemed for all purposes to be
holders of the Rational Common Shares delivered to them or
the custodian on their behalf.
ARTICLE 8.
PURCHASE FOR CANCELLATION
8.1.    Subject to applicable law and the articles and by-laws the
Company, the Company may at any time and from time to time
purchase for cancellation all or any part of the outstanding
Exchangeable Shares at any price by tender to all the
holders of record of Exchangeable Shares then outstanding at
any price per share together with an amount equal to all
declared and unpaid dividends for which the record date has
occurred prior to the date of purchase. If in response to an
invitation for tenders under the provisions of this
section 8.1, more Exchangeable Shares are tendered at a

the Voting Rights and will hold the Exchange Right and the Automatic
Exchange Rights to enable the Trustee to exercise those rights, in each
case as trustee for and on behalf of the Beneficiaries as provided in
this trust agreement.

the provisions of this trust agreement.  Rational hereby acknowledges
receipt from the Trustee as trustee for and on behalf of the
Beneficiaries of good and valuable consideration (and the adequacy of

Beneficiaries of their right to instruct the Trustee with respect to the
exercise of the Voting Rights in respect of the Exchangeable Shares of
the Beneficiaries.

3.3.    Beneficial Ownership of Deposited Shares

        Except with respect to the Voting Rights, Rational will remain the

3.6.    Release of Deposited Shares

        Notwithstanding any other provision of this trust agreement, in
the event that:

(a) a Beneficiary is entitled to receive Rational Common Shares
as a result of a retraction or redemption of Exchangeable
Shares by Acquisition Sub pursuant to either Article 6 or
Article 7 of the Share Provisions and in respect of which a
Retraction Call Right or a Redemption Call Right, as the
case may be, has not been exercised by Holding ULC, Rational
will demand from the Trustee and the Trustee, as the agent
of Rational and Acquisition Sub and on behalf of Rational
and Acquisition Sub, will release and deliver to the
Transfer Agent free from the trusts of this trust agreement
that number of Deposited Shares which are the subject of
each retraction or redemption for immediate delivery to the
Beneficiary, and that delivery will constitute delivery of
those Deposited Shares by or on behalf of Rational and
Acquisition Sub;

(b) a Beneficiary would be entitled to receive Rational Common
Shares as a result of the exercise by Holding ULC of a
Retraction Call Right, Redemption Call Right or Liquidation
Call Right, the Trustee, upon instructions from Rational, as
the agent of Rational and Holding ULC and on behalf of
Rational and Holding ULC, will release and transfer to that
Beneficiary free from the trusts of this trust agreement
that number of Deposited Shares which are the subject of
those rights;

(c) a Beneficiary would be entitled to receive Rational Common
Shares as a result of the exercise by the Trustee on behalf
of the Beneficiary of the Exchange Right or Automatic
Exchange Right, the Trustee, as the agent of Rational and on
behalf of Rational, will release and transfer to that
Beneficiary free from the trusts of this trust agreement
that number of Deposited Shares which are the subject of
those rights; and

(d) upon a release and transfer, legal title to those Deposited
Shares will be transferred to the Beneficiary and Rational
will immediately instruct and authorize its transfer agent
to record that transfer in the stock transfer register of
Rational, to issue and deliver to the Beneficiary one or
more share certificates representing the Deposited Shares
registered in the name of the Beneficiary and to do all
other acts as may be necessary to give effect to the
foregoing.

ARTICLE 4.

EXERCISE OF VOTING RIGHTS

4.1.    Voting Rights

        The Trustee, as the holder of record of the Deposited Shares, will
be entitled to all of the Voting Rights, including the right to vote in
person or by proxy the Deposited Shares on any matters, questions,
proposals or propositions that may properly come before the shareholders
of Rational at a Rational Meeting or in connection with a Rational
Consent. The Voting Rights will be and remain vested in and exercised by
the Trustee. Subject to section 6.15:

(a) the Trustee will exercise the Voting Rights only on the basis
of instructions received pursuant to this Article 4 from
Beneficiaries appearing on the List as to the voting of the
Voting Rights at the time at which the Rational Meeting is
held or a Rational Consent is sought; and

(b) to the extent that no instructions are received from a
Beneficiary with respect to the Voting Rights to which that
Beneficiary is entitled, the Trustee will not exercise or
permit the exercise of those Voting Rights.

4.2.    Number of Votes

        With respect to all meetings of shareholders of Rational at which
holders of Rational Common Shares are entitled to vote (each, a "Rational
Meeting") and with respect to all written consents sought by Rational
from its shareholders including the holders of Rational Common Shares
(each, a "Rational Consent"), each Beneficiary will be entitled to
instruct the Trustee to cast and exercise one of the votes comprised in
the Voting Rights for each Exchangeable Share owned of record by that
Beneficiary on the record date established by Rational or by applicable
law for the Rational Meeting or Rational Consent, as the case may be (the
"Beneficiary Votes"), in respect of each matter, question, proposal or
proposition to be voted on at the Rational Meeting or in connection with
the Rational Consent.

4.3.    Mailings to Shareholders

        With respect to each Rational Meeting and Rational Consent, the
Trustee will use its reasonable efforts to mail or cause to be mailed (or
otherwise communicate in the same manner as Rational utilizes in
communications to holders of Rational Common Shares, subject to the
Trustee being advised in writing of that method and its ability to
provide that method of communication) to each of the Beneficiaries named
in the List referred to in section 4.6, which mailing or communication,
to the extent practicable, will commence on the same day as the mailing
or notice (or other communication) is commenced by Rational to its
shareholders:

(a) a copy of the notice, together with any related materials to
be provided to shareholders of Rational;

(b) a statement that the Beneficiary is entitled to instruct the
Trustee as to the exercise of the Beneficiary Votes with
respect to the Rational Meeting or Rational Consent or,
pursuant to section 4.7, to attend the Rational Meeting and
to exercise personally the Beneficiary Votes at the meeting;

(c) a statement as to the manner in which instructions may be
given to the Trustee, including an express indication that
instructions may be given to the Trustee to give:
(i) a proxy to the Beneficiary or his designee to exercise
personally the Beneficiary Votes; or
(ii) a proxy to a designated agent or other representative
of the management of Rational to exercise the
Beneficiary Votes;

(d) a statement that if no instructions are received from the
Beneficiary, the Beneficiary Votes to which that Beneficiary
is entitled will not be exercised;

(e) a form of direction whereby the Beneficiary may so direct and
instruct the Trustee as contemplated in this Article; and

(f) a statement of the time and date by which instructions must
be received by the Trustee in order to be binding upon it,
which in the case of a Rational Meeting will not be earlier
than the close of business on the second Business Day prior
to the meeting, and of the method for revoking or amending
those instructions.

The materials referred to above are to be provided to the Trustee by
Rational.

        For the purpose of determining Beneficiary Votes to which a
Beneficiary is entitled in respect of any Rational Meeting or Rational
Consent, the number of Exchangeable Shares owned of record by the
Beneficiary will be determined at the close of business on the record
date established by Rational or by applicable law for purposes of
determining shareholders entitled to vote at the Rational Meeting.
Rational will notify the Trustee of any decision of the Board of
Directors of Rational with respect to the calling of any Rational Meeting
and will provide all necessary information and materials to the Trustee
in each case promptly and in any event in sufficient time to enable the
Trustee to perform its obligations contemplated by this section 4.3.

4.4.    Copies of Shareholder Information

        Rational will deliver to the Trustee (i) copies of all proxy
materials (including notices of Rational Meetings, but excluding proxies
to vote Rational Common Shares), information statements, reports
(including without limitation, all interim and annual financial
statements) and other written communications that, in each case, are to
be distributed from time to time to holders of Rational Common Shares in
sufficient quantities and in sufficient time so as to enable the Trustee
to send those materials to each Beneficiary at the same time as those
materials are first sent to holders of Rational Common Shares and
(ii) one copy of each proxy to vote Rational Common Shares. The Trustee
will mail or otherwise send to each Beneficiary, at the expense of
Rational, copies of those materials (and all materials specifically
directed to the Beneficiaries or to the Trustee for the benefit of the
Beneficiaries by Rational) received by the Trustee from Rational
contemporaneously with the sending of those materials to holders of
Rational Common Shares. The Trustee will also make available for
inspection by any Beneficiary at the Trustee's principal office in the
City of New York all proxy materials, information statements, reports and
other written communications that are:
(a) received by the Trustee as the registered holder of the
Deposited Shares and made available by Rational generally to
the holders of Rational Common Shares; or
(b) specifically directed to the Beneficiaries or to the Trustee
for the benefit of the Beneficiaries by Rational.

4.5.    Other Materials

        As soon as reasonably practicable after receipt by Rational or
shareholders of Rational (if that receipt is known by Rational) of any
material sent or given by or on behalf of a third party to holders of
Rational Common Shares generally, including without limitation, dissident
proxy and information circulars (and related information and material)
and tender and exchange offer circulars (and related information and
material), Rational will use its reasonable efforts to obtain and deliver
to the Trustee copies of those materials in sufficient quantities so as
to enable the Trustee to forward the material (unless the same has been
provided directly to Beneficiaries by the third party) to each
Beneficiary as soon as possible.  As soon as reasonably practicable after
receipt of those materials, the Trustee will mail or otherwise send to
each Beneficiary, at the expense of Rational, copies of all those
materials received by the Trustee from Rational. The Trustee will also
make available for inspection by any Beneficiary at the Trustee's
principal office in the City of New York copies of all those materials.

4.6.    List of Persons Entitled to Vote

        Acquisition Sub will, (a) prior to each annual, general and special
Rational Meeting or the seeking of any Rational Consent and (b) promptly
upon each request made at any time by the Trustee in writing, prepare or
cause to be prepared a list (the most current list delivered to the
Trustee being the "List") of the names and addresses of the Beneficiaries
arranged in alphabetical order (and, if requested, broken down by
jurisdiction of residence) and showing the number of Exchangeable Shares
held of record by each Beneficiary, in each case at the close of business
on the date specified by the Trustee in the request or, in the case of a
List prepared in connection with a Rational Meeting or a Rational
Consent, at the close of business on the record date established by
Rational or pursuant to applicable law for determining the holders of
Rational Common Shares entitled to receive notice of and/or to vote at
that Rational Meeting or to give consent in connection with that Rational
Consent. Each List will be delivered to the Trustee promptly after
receipt by Acquisition Sub of a request or the record date for a meeting
or seeking of consent, as the case may be, and in any event within
sufficient time to enable the Trustee to perform its obligations under
this trust agreement. Rational agrees to give Acquisition Sub written
notice (with a copy to the Trustee) of the calling of any Rational
Meeting or the seeking of any Rational Consent, together with the record
dates, sufficiently prior to the date of the calling of the meeting or
seeking of the consent so as to enable Acquisition Sub to perform its
obligations under this section 4.6.

4.7.    Entitlement to Direct Votes

        Any Beneficiary named in a List prepared in connection with any
Rational Meeting or Rational Consent will be entitled (a) to instruct the
Trustee in the manner described in section 4.3 with respect to the
exercise of the Beneficiary Votes to which that Beneficiary is entitled
or (b) to attend the meeting and personally exercise at the meeting, as
the proxy of the Trustee, the Beneficiary Votes to which the Beneficiary
is entitled.

4.8.    Voting by Trustee, and Attendance of Trustee Representative at
Meeting

(a) In connection with each Rational Meeting and Rational
Consent, the Trustee will exercise, either in person or by
proxy, in accordance with the instructions received from a
Beneficiary pursuant to section 4.3, the Beneficiary Votes as
to which that Beneficiary is entitled to direct the vote (or
any lesser number of Beneficiary Votes as may be set out in
the instructions); provided, however, that those written
instructions are received by the Trustee from the Beneficiary
prior to the time and date fixed by the Trustee for receipt
of those instructions in the notice given by the Trustee to
the Beneficiary pursuant to section 4.3.

(b) The Trustee will cause a representative who is empowered by
it to sign and deliver, on behalf of the Trustee, proxies for
Voting Rights to attend each Rational Meeting. Upon
submission by a Beneficiary (or its designee) of
identification satisfactory to the Trustee's representative,
and at the Beneficiary's request, the representative will
sign and deliver to that Beneficiary (or its designee) a
proxy to exercise personally the Beneficiary Votes as to
which that Beneficiary is otherwise entitled under this trust
agreement to direct the vote, if that Beneficiary either

(i) has not previously given the Trustee instructions
pursuant to section 4.3 in respect of the meeting or

(ii) submits to the representative written revocation of any
previous instructions. At the meeting, the Beneficiary
exercising those Beneficiary Votes will have the same rights
as the Trustee to speak at the meeting in favour of any
matter, question, proposal or proposition, to vote by way of
ballot at the meeting in respect of any matter, question,
proposal or proposition, and to vote at the meeting by way of
a show of hands in respect of any matter, question or
proposition.

4.9.    Distribution of Written Materials

        Any written materials distributed by the Trustee pursuant to this
trust agreement will be sent by mail (or otherwise communicated in the
same manner as Rational utilizes in communications to holders of Rational
Common Shares, subject to the Trustee being advised in writing of that
method of communication and its ability to provide that method of
communication) to each Beneficiary at its address as shown on the List.
Acquisition Sub will provide or cause to be provided to the Trustee for
this purpose, on a timely basis and without charge or other expense:

(a) a current List; and

(b) upon the request of the Trustee, mailing labels to enable the
Trustee to carry out its duties under this trust agreement.

4.10.   Termination of Voting Rights

        All of the rights of a Beneficiary with respect to the Beneficiary
Votes exercisable in respect of the Exchangeable Shares held by that
Beneficiary, including the right to instruct the Trustee as to the voting
of or to vote personally the Beneficiary Votes, will be deemed to be
surrendered by the Beneficiary to Rational or Holding ULC, as the case
may be, and those Beneficiary Votes and the Voting Rights represented by
those Beneficiary Votes will cease immediately upon the delivery by that
holder to the Trustee of the certificates representing those Exchangeable
Shares in connection with the exercise by the Beneficiary of the Exchange
Right or the occurrence of the automatic exchange of Exchangeable Shares
for Rational Common Shares, as specified in Article 5 (unless, in either
case, Rational has not delivered the requisite Rational Common Shares
issuable in exchange for the Exchangeable Shares to the Trustee for
delivery to the Beneficiaries), or upon the redemption of Exchangeable
Shares pursuant to Article 6 or 7 of the Share Provisions, or upon the
effective date of the liquidation, dissolution or winding-up of
Acquisition Sub pursuant to Article 5 of the Share Provisions, or upon
the purchase of Exchangeable Shares from the holder by Holding ULC
pursuant to the exercise by Holding ULC of the Retraction Call Right, the
Redemption Call Right or the Liquidation Call Right.

ARTICLE 5.

EXCHANGE RIGHT AND AUTOMATIC EXCHANGE

5.1.    Grant and Ownership of the Exchange Right

        Rational hereby grants to the Trustee as trustee for and on behalf
of, and for the use and benefit of, the Beneficiaries (i) the right (the
"Exchange Right"), upon the occurrence and during the continuance of an
Insolvency Event, to require Rational to purchase from each or any
Beneficiary all or any part of the Exchangeable Shares held by the
Beneficiary and (ii) the Automatic Exchange Rights, all in accordance
with the provisions of this trust agreement.  Rational hereby
acknowledges receipt from the Trustee as trustee for and on behalf of the
Beneficiaries of good and valuable consideration (and the adequacy of the
consideration) for the grant of the Exchange Right and the Automatic
Exchange Rights by Rational to the Trustee. During the term of the Trust
and subject to the terms and conditions of this trust agreement, the
Trustee will possess and be vested with full legal ownership of the
Exchange Right and the Automatic Exchange Rights and will be entitled to
exercise all of the rights and powers of an owner with respect to the
Exchange Right and the Automatic Exchange Rights, provided that the
Trustee will:

(a) hold the Exchange Right and the Automatic Exchange Rights and
the legal title to those rights as trustee solely for the use
and benefit of the Beneficiaries in accordance with the
provisions of this trust agreement; and

(b) except as specifically authorized by this trust agreement,
have no power or authority to exercise or otherwise deal in
or with the Exchange Right or the Automatic Exchange Rights,
and the Trustee will not exercise those rights for any
purpose other than the purposes for which the Trust is
created pursuant to this trust agreement.

5.2.    Legended Share Certificates

        Acquisition Sub will cause each certificate representing
Exchangeable Shares to bear an appropriate legend notifying the
Beneficiaries of:

(a) their right to instruct the Trustee with respect to the
exercise of the Exchange Right in respect of the Exchangeable
Shares held by a Beneficiary; and

(b) the Automatic Exchange Rights.

5.3.    General Exercise of Exchange Right

        The Exchange Right will be and remain vested in and exercisable by
the Trustee. Subject to section 6.15, the Trustee will exercise the
Exchange Right only on the basis of instructions received pursuant to
this Article 5 from Beneficiaries appearing on the List. To the extent
that no instructions are received from a Beneficiary with respect to the
Exchange Right, the Trustee will not exercise or permit the exercise of
the Exchange Right.

5.4.    Purchase Price

        The total purchase price payable by Rational for each Exchangeable
Share to be purchased by Rational under the Exchange Right will be an
amount per share equal to (a) the Current Market Price of a Rational
Common Share on the last Business Day prior to the day of closing of the
purchase and sale of that Exchangeable Share under the Exchange Right,
which will be satisfied in full by Rational causing to be sent to that
holder one Rational Common Share, plus (b) to the extent not paid by
Acquisition Sub, an additional amount equivalent to the full amount of
all declared and unpaid dividends on each Exchangeable Share held by that
holder on any dividend record date which occurred prior to the closing of
the purchase and sale.  In connection with each exercise of the Exchange
Right, Rational will provide to the Trustee an Officer's Certificate
setting out the calculation of the purchase price for each Exchangeable
Share, upon which the Trustee may conclusively rely without any duty to
verify the price.  The total purchase price for each Exchangeable Share
so purchased may be satisfied only by the transfer by the Trustee to the
relevant Beneficiary of one Rational Common Share and, on the applicable
payment date, delivery by the Trustee to the relevant Beneficiary of a
cheque of Rational (or, if Rational has delivered sufficient funds to the
Trustee, a cheque of the Trustee) for the balance, if any, of the
purchase price without interest (but less any amounts withheld pursuant
to section 5.13).

5.5.    Exercise Instructions

        Subject to the terms and conditions set out in this trust
agreement, a Beneficiary will be entitled, upon the occurrence and during
the continuance of an Insolvency Event, to instruct the Trustee to
exercise the Exchange Right with respect to all or any part of the
Exchangeable Shares registered in the name of that Beneficiary on the
books of Acquisition Sub.  To cause the exercise of the Exchange Right by
the Trustee, the Beneficiary will deliver to the Trustee, in person or by
mail, at its principal office in New York, New York, the certificates
representing the Exchangeable Shares which that Beneficiary desires
Rational to purchase, duly endorsed in blank for transfer, and
accompanied by any other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the Business Corporations
Act (Ontario) and the by-laws of Acquisition Sub and any additional
documents and instruments as the Trustee, Rational or Acquisition Sub may
reasonably require together with:

(a) a duly completed form of notice of exercise of the Exchange
Right, contained on the reverse of or attached to the
Exchangeable Share certificates, stating

(i) that the Beneficiary thereby instructs the Trustee to
exercise the Exchange Right so as to require Rational
to purchase from the Beneficiary the number of
Exchangeable Shares specified in the notice,

(ii) that the Beneficiary has good title to and owns all
Exchangeable Shares to be acquired by Rational free and
clear of all liens, claims, security interests, adverse
claims and encumbrances,

(iii) the names in which the certificates representing
Rational Common Shares issuable in connection with the
exercise of the Exchange Right are to be issued, and

(iv) the names and addresses of the persons to whom those
new certificates should be delivered; and
(b) payment (or evidence satisfactory to the Trustee, Acquisition
Sub and Rational of payment) of the taxes (if any) payable as
contemplated by section 5.8 of this trust agreement.
If only a part of the Exchangeable Shares represented by any certificate
or certificates delivered to the Trustee are to be purchased by Rational
under the Exchange Right, a new certificate for the balance of the
Exchangeable Shares will be issued to the holder at the expense of
Acquisition Sub.

5.6.    Delivery of Rational Common Shares; Effect of Exercise

        Promptly after receipt of the certificates representing the
Exchangeable Shares which the Beneficiary desires Rational to purchase
under the Exchange Right, together with all documents and instruments of
transfer and a duly completed form of notice of exercise of the Exchange
Right (and payment of taxes, if any, payable as contemplated by
section 5.8 or evidence of payment), duly endorsed for transfer to
Rational, the Trustee will notify Rational and Acquisition Sub of its
receipt of the same, which notice to Rational and Acquisition Sub will
constitute exercise of the Exchange Right by the Trustee on behalf of the
holder of the Exchangeable Shares, and Rational will then promptly
instruct and authorize the Trustee to transfer to the Beneficiary of
those Exchangeable Shares (or to any other persons, if any, properly
designated by the Beneficiary) from the Deposited Shares the number of
Rational Common Shares deliverable in connection with the exercise of the
Exchange Right, and on the applicable payment date cheques for the
balance, if any, of the total purchase price without interest (but less
any amounts withheld pursuant to section 5.13); provided, however, that
no delivery will be made unless and until the Beneficiary making the
request has paid (or provided evidence satisfactory to Acquisition Sub
and Rational of the payment of) the taxes (if any) payable as
contemplated by section 5.8 of this trust agreement.  Immediately upon
the giving of notice by the Trustee to Rational and Acquisition Sub of
the exercise of the Exchange Right as provided in this section 5.6, the
closing of the transaction of purchase and sale contemplated by the
Exchange Right will be deemed to have occurred and the holder of those
Exchangeable Shares will be deemed to have transferred to Rational all of
that holder's right, title and interest in and to those Exchangeable
Shares and the related interest in the Trust Estate and will cease to be
a holder of those Exchangeable Shares and will not be entitled to
exercise any of the rights of a holder in respect of those Exchangeable
Shares, other than the right to receive his proportionate part of the
total purchase price for those Exchangeable Shares (together with a
cheque for the balance, if any, of the total purchase price without
interest), unless the requisite number of Rational Common Shares are not
authorized by Rational to be delivered by the Trustee to the Beneficiary
within five Business Days of the date of the giving of notice by the
Trustee, in which case the rights of the Beneficiary will remain
unaffected until the Rational Common Shares are so delivered and any
cheque is delivered and paid. Upon authorization by Rational to the
Trustee of delivery of the Rational Common Shares, the Trustee will
transfer from the Deposited Shares those Rational Common Shares to the
Beneficiary (or to any other persons, if any, properly designated by the
Beneficiary). Concurrently with the Beneficiary ceasing to be a holder of
Exchangeable Shares, the Beneficiary will be considered and deemed for
all purposes to be the holder of the Rational Common Shares delivered to
it pursuant to the Exchange Right.

5.7.    Exercise of Exchange Right Subsequent to Retraction

        In the event that a Beneficiary has exercised its right under
Article 6 of the Share Provisions to require Acquisition Sub to redeem
any or all of the Exchangeable Shares held by the Beneficiary (the
"Retracted Shares") and is notified by Acquisition Sub pursuant to
section 6.6 of the Share Provisions that Acquisition Sub will not be
permitted as a result of solvency requirements or other provisions of
applicable law to redeem all those Retracted Shares, and provided that
Holding ULC has not exercised the Retraction Call Right with respect to
the Retracted Shares and that the Beneficiary has not revoked the
retraction request delivered by the Beneficiary to Acquisition Sub
pursuant to section 6.1 of the Share Provisions, the retraction request
will constitute and will be deemed to constitute notice from the
Beneficiary to the Trustee instructing the Trustee to exercise the
Exchange Right with respect to those Retracted Shares that Acquisition
Sub is unable to redeem.  In that event, Acquisition Sub hereby agrees
with the Trustee and in favour of the Beneficiary to immediately notify
the Trustee of the prohibition against Acquisition Sub redeeming all of
the Retracted Shares and to promptly forward or cause to be forwarded to
the Trustee all relevant materials delivered by the Beneficiary to
Acquisition Sub or to the Transfer Agent (including without limitation, a
copy of the retraction request delivered pursuant to section 6.1 of the
Share Provisions) in connection with the proposed redemption of the
Retracted Shares and the Trustee will then exercise the Exchange Right
with respect to the Retracted Shares that Acquisition Sub is not
permitted to redeem and will request Rational to purchase those shares in
accordance with the provisions of this Article 5.

5.8.    Stamp or Other Transfer Taxes

        Upon any sale of Exchangeable Shares to Rational pursuant to the
Exchange Right or the Automatic Exchange Rights, the share certificate or
certificates representing Rational Common Shares to be delivered in
connection with the payment of the total purchase price will be issued in
the name of the Beneficiary of the Exchangeable Shares so sold or in any
names as the Beneficiary may otherwise direct in writing without charge
to the holder of the Exchangeable Shares so sold; provided, however, that
the Beneficiary (a) will pay (and none of Rational, Acquisition Sub or
the Trustee will be required to pay) any documentary, stamp, transfer or
other taxes that may be payable in respect of any transfer involved in
the issuance or delivery of those shares to a person other than the
Beneficiary or (b) will provide evidence to the satisfaction of Rational
and Acquisition Sub that those taxes, if any, have been paid.

5.9.    Notice of Insolvency Event

        As soon as practicable following the occurrence of an Insolvency
Event or any event that with the giving of notice or the passage of time
or both would be an Insolvency Event, Acquisition Sub and Rational will
give written notice of that event to the Trustee. As soon as practicable
following the receipt of notice from Acquisition Sub or Rational of the
occurrence of an Insolvency Event, or upon the Trustee becoming aware of
an Insolvency Event, the Trustee will mail by first class mail to each
Beneficiary, at the expense of Rational, a notice of the Insolvency Event
in the form provided by Rational, which notice will contain a brief
statement of the rights of the Beneficiaries with respect to the Exchange
Right.

5.10.   Qualification of Rational Common Shares

        Rational covenants that if any Rational Common Shares (or other
shares or securities into which Rational Common Shares may be
reclassified or changed as contemplated by the Support Agreement) to be
transferred and delivered pursuant to the Exchange Right or the
Automatic Exchange Rights require registration or qualification with or
approval of or the filing of any document, including any prospectus or
similar document or the taking of any proceeding with or the obtaining
of any order, ruling or consent from any governmental or regulatory
authority (i) under the Canadian provincial securities or other law or
regulation or pursuant to the rules and regulations of any securities or
other regulatory authority applicable to holders who are resident in the
provinces of Ontario or Quebec or (ii) under any United States federal
or state securities or other law or regulation or pursuant to the rules
and regulations of any United States securities or other regulatory
authority, or the fulfilment of any other United States legal
requirement or Canadian legal requirement applicable to holders who are
resident in the provinces of Ontario or Quebec before those shares (or
those other shares or securities) may be issued, transferred and/or
delivered by Rational at the direction of Acquisition Sub or Holding ULC
to the holder of surrendered Exchangeable Shares or in order that those
shares (or those other shares or securities) may be freely traded
thereafter through the facilities of a stock exchange or market in the
United States or through NASDAQ provided that first trade is made in
accordance with the rules of the stock exchange or market upon which the
trade is made or the rules of NASDAQ in accordance with all laws
applicable to that stock exchange or market or applicable to NASDAQ
(other than any restrictions of general application on transfer by
reason of a holder being a "control person" for purposes of Canadian
provincial securities law or an "affiliate" of Rational for purposes of
United States federal or state securities law), Rational will in good
faith expeditiously take all actions and do all things as are necessary
or desirable to cause those Rational Common Shares (or those other
shares or securities) to be and remain duly registered, qualified or
approved under United States and/or Canadian law, as the case may be.
Rational will in good faith expeditiously take all actions and do all
things as are reasonably necessary or desirable to cause all Rational
Common Shares (or those other shares or securities) to be delivered
under this Agreement to be listed, quoted or posted for trading on all
stock exchanges and quotation systems on which outstanding Rational
Common Shares (or those other shares or securities) have been listed by
Rational and remain listed and are quoted or posted for trading at that
time.

5.11.   Rational Common Shares

        Rational hereby represents, warrants and covenants that the
Rational Common Shares deliverable as described in this trust agreement
will be duly authorized and validly issued as fully paid and non-
assessable and will be free and clear of any lien, claim or encumbrance.

5.12.   Automatic Exchange on Liquidation of Rational

(a) Rational will give the Trustee written notice of each of the
following events at the time set out below:

(i) in the event of any determination by the Board of
Directors of Rational to institute voluntary
liquidation, dissolution or winding-up proceedings with
respect to Rational or to effect any other distribution
of assets of Rational among its shareholders for the
purpose of winding up its affairs, at least 60 days
prior to the proposed effective date of the
liquidation, dissolution, winding-up or other
distribution; and

(ii) as soon as practicable following the earlier of
(A) receipt by Rational of notice of, and (B) Rational
otherwise becoming aware of, any threatened or
instituted claim, suit, petition or other proceedings
with respect to the involuntary liquidation,
dissolution or winding-up of Rational or to effect any
other distribution of assets of Rational among its
shareholders for the purpose of winding up its affairs,
in each case where Rational has failed to contest in
good faith the proceeding commenced in respect of
Rational within 30 days of becoming aware of the
proceeding.

(b) As soon as practicable following receipt by the Trustee from
Rational of notice of any event (a "Liquidation Event")
contemplated by section 5.12(a)(i) or 5.12(a)(ii), the
Trustee will give notice of that event to the Beneficiaries.
The notice will be provided by Rational to the Trustee and
will include a brief description of the automatic exchange of
Exchangeable Shares for Rational Common Shares provided for
in section 5.12(c).

(c) In order that the Beneficiaries will be able to participate
on a pro rata basis with the holders of Rational Common
Shares in the distribution of assets of Rational in
connection with a Liquidation Event, on the fifth Business
Day prior to the effective date (the "Liquidation Event
Effective Date") of a Liquidation Event all of the then
outstanding Exchangeable Shares will be automatically
exchanged for Rational Common Shares. To effect this
automatic exchange, Rational will purchase on the fifth
Business Day prior to the Liquidation Event Effective Date
each Exchangeable Share then outstanding and held by
Beneficiaries, and each Beneficiary will sell the
Exchangeable Shares held by it at that time, for a total
purchase price per share equal to (a) the Current Market
Price of a Rational Common Share on the fifth Business Day
prior to the Liquidation Event Effective Date, which will be
satisfied in full by Rational authorizing and directing the
Trustee to transfer to the Beneficiary one Rational Common
Share, and (b) to the extent not paid by Acquisition Sub, an
additional amount equivalent to the full amount of all
declared and unpaid dividends on each Exchangeable Share held
by the holder on any dividend record date which occurred
prior to the date of the exchange.  In connection with this
automatic exchange, Rational will provide to the Trustee an
Officer's Certificate setting out the calculation of the
purchase price for each Exchangeable Share, upon which the
Trustee may conclusively rely without any duty to verify the
price.

(d) On the fifth Business Day prior to the Liquidation Event
Effective Date, the closing of the transaction of purchase
and sale contemplated by the automatic exchange of
Exchangeable Shares for Rational Common Shares will be deemed
to have occurred, and each Beneficiary will be deemed to have
transferred to Rational all of the Beneficiary's right, title
and interest in and to that Beneficiary's Exchangeable Shares
and the related interest in the Trust Estate and will cease
to be a holder of the Exchangeable Shares and Rational will
authorize and direct the Trustee to transfer to the
Beneficiary the Rational Common Shares issuable upon the
automatic exchange of Exchangeable Shares for Rational Common
Shares and on the applicable payment date will deliver to the
Trustee for delivery to the Beneficiary a cheque for the
balance, if any, of the total purchase price for the
Exchangeable Shares without interest but less any amounts
withheld pursuant to section 5.13. Concurrently with the
Beneficiary ceasing to be a holder of Exchangeable Shares,
the Beneficiary will be considered and deemed for all
purposes to be the holder of the Rational Common Shares
issued pursuant to the automatic exchange of Exchangeable
Shares for Rational Common Shares and the certificates held
by the Beneficiary previously representing the Exchangeable
Shares exchanged by the Beneficiary with Rational pursuant to
the automatic exchange will then be deemed to represent
Rational Common Shares issued to the Beneficiary by Rational
pursuant to the automatic exchange. Upon the request of a
Beneficiary and the surrender by the Beneficiary of
Exchangeable Share certificates deemed to represent Rational
Common Shares, duly endorsed in blank and accompanied by any
instruments of transfer as Rational may reasonably require,
Rational will deliver or cause to be delivered to the
Beneficiary certificates representing Rational Common Shares
of which the Beneficiary is the holder.

5.13.   Withholding Rights

        Rational, Acquisition Sub and the Trustee will be entitled to
deduct and withhold from any consideration otherwise payable under this
trust agreement to any holder of Exchangeable Shares or Rational Common
Shares any amounts as Rational, Acquisition Sub or the Trustee is
required or permitted to deduct and withhold with respect to that payment
under the Income Tax Act (Canada), the United States Internal Revenue
Code of 1986 or any provision of provincial, state, local or foreign tax
law, in each case as amended or succeeded. To the extent that amounts are
so withheld, the withheld amounts will be treated for all purposes as
having been paid to the holder of the shares in respect of which the
deduction and withholding was made, provided that the withheld amounts
are actually remitted to the appropriate taxing authority. To the extent
that the amounts so required or permitted to be deducted or withheld from
any payment to a holder exceeds the cash portion of the consideration
otherwise payable to the holder, Rational, Acquisition Sub and the
Trustee are hereby authorized to sell or otherwise dispose of any portion
of the consideration as is necessary to provide sufficient funds to
Rational, Acquisition Sub or the Trustee, as the case may be, to enable
it to comply with the deduction or withholding requirements and Rational,
Acquisition Sub or the Trustee will notify the holder and remit to the
holder any unapplied balance of the net proceeds of the sale.

ARTICLE 6.

        The rights, powers, duties and authorities of the Trustee under

the Beneficiaries in accordance with the provisions of this
trust agreement;

(e) exercising the Exchange Right and enforcing the benefit of
the Automatic Exchange Rights, in each case in accordance
with the provisions of this trust agreement, and, in
connection with those exercises, receiving from Beneficiaries
Exchangeable Shares and other requisite documents and
transferring and delivering to those Beneficiaries Rational
Common Shares and cheques, if any, to which those
Beneficiaries are entitled upon the exercise of the Exchange
Right or pursuant to the Automatic Exchange Rights, as the
case may be;

(f) holding title to the Trust Estate;

(g) investing any moneys forming, from time to time, a part of
the Trust Estate as provided in this trust agreement;

Beneficiaries to enforce the obligations of Rational and
Acquisition Sub under this trust agreement in accordance with
the provisions of this trust agreement; and

(i) taking any other actions and doing all other things as are
specifically provided in this trust agreement.

        In the exercise of those rights, powers, duties and authorities the
Trustee will have (and is granted) all incidental and additional rights,
powers, duties and authority not in conflict with any of the provisions
of this trust agreement as the Trustee, acting in good faith and in the
reasonable exercise of its discretion, may deem necessary, appropriate or
desirable to effect the purpose of the Trust, provided that the Trustee
will have no obligation to exercise any such discretionary rights,
powers, duties or authorities. Any exercise of these discretionary
rights, powers, duties and authorities by the Trustee will be final,
conclusive and binding upon all persons.  This trust agreement expressly
sets out all the duties of the Trustee with respect to all matters
pertinent to this trust agreement.  The Trustee will not be bound by the
provisions of any other agreement among the other parties to this trust
agreement.  No implied duties will be read into this trust agreement as
against the Trustee.

becomes aware that any material conflict of interest exists in its acting
as Trustee under this trust agreement and its role in any other capacity,
either eliminate the material conflict of interest or resign in the
manner and with the effect specified in Article 9. If, notwithstanding
the foregoing provisions of this section 6.2, the Trustee has a material
conflict of interest, the validity and enforceability of this trust
agreement will not be affected in any manner by reason only of the
existence of the material conflict of interest. If the Trustee
contravenes the foregoing provisions of this section 6.2, any interested
party may apply to the Ontario Superior Court of Justice for an order
that the Trustee be replaced as Trustee under this trust agreement.

6.3.    Dealings with Transfer Agents, Registrars, etc.

transfer agents any information readily available from the
records maintained by them which the Trustee may reasonably
require for the discharge of its duties and responsibilities
under this trust agreement and (ii) from the transfer agent
of Rational Common Shares, and any subsequent transfer agent
of those shares, the share certificates representing shares
issuable or transferable upon the exercise from time to time
of the Exchange Right and pursuant to the Automatic Exchange
Rights in the manner specified in Article 5.

        Rational and Acquisition Sub irrevocably authorize their respective
registrars and transfer agents to comply with these requests.  Rational
covenants that it will supply its transfer agent with duly executed share
certificates for the purpose of completing the exercise from time to time
of the Exchange Right and the Automatic Exchange Rights in each case
pursuant to Article 5.

6.4.    Books and Records

        The Trustee will keep available for inspection by Rational and
Acquisition Sub at the Trustee's principal office in New York, New York

created by this trust agreement, including without limitation, all
relevant data relating to mailings and instructions to and from
Beneficiaries and all transactions pursuant to the Exchange Right and the
Automatic Exchange Rights. On or before March 31, 2001 and on or before
March 31 in every following year, so long as the Deposited Shares are on
deposit with the Trustee, the Trustee will transmit to Rational and
Acquisition Sub a brief report, dated as of the preceding December 31,
with respect to:

(a) the property and funds comprising the Trust Estate as of that
date;

(b) the number of exercises of the Exchange Right, if any, and
the aggregate number of Exchangeable Shares delivered by the
Trustee to Beneficiaries in consideration of the transfer of
Rational Common Shares in connection with the Exchange Right,
during the fiscal year ended on that December 31; and
(c) any material actions taken by the Trustee with respect to the
Trust Estate in the performance of its duties under this
trust agreement which it had not previously reported.

6.5.    Income Tax Returns and Reports

        The Trustee will, to the extent necessary, prepare and file or
cause to be prepared and filed on behalf of the Trust appropriate United
States and Canadian income tax returns and any other returns or reports
as may be required by applicable law or pursuant to the rules and
regulations of any securities exchange or other trading system through
which the Exchangeable Shares are traded and in connection with this may
obtain the advice of and assistance from any experts as the Trustee may
reasonably consider necessary or advisable.  If requested by the Trustee,
Rational will retain those experts for providing this advice or
assistance to the Trustee.

6.6.    Indemnification Prior to Certain Actions by Trustee

        The Trustee will not be obligated to exercise any or all of the
rights, duties, powers or authorities vested in it by this trust
agreement at the request, order or direction of any Beneficiary unless
that Beneficiary has furnished to the Trustee reasonable funding,
security or indemnity against the costs, expenses and liabilities which
may be incurred by the Trustee, provided that no Beneficiary will be
obligated to furnish to the Trustee that funding, security or indemnity
in connection with the exercise by the Trustee of any of its rights,
duties, powers and authorities with respect to the Deposited Shares
pursuant to Article 4, subject to section 6.15, and with respect to the
Exchange Right pursuant to Article 5, subject to section 6.15, and with
respect to the Automatic Exchange Rights pursuant to Article 5, subject
to section 6.15.

        None of the provisions contained in this trust agreement will
require the Trustee to expend or risk its own funds or otherwise incur
financial liability in the exercise of any of its rights, powers, duties,
or authorities unless funded, given security or indemnified as set out in
this section.

6.7.    Action of Beneficiaries

        No Beneficiary will have the right to institute any action, suit or
proceeding or to exercise any other remedy authorized by this trust
agreement for the purpose of enforcing any of its rights or for the
execution of any trust or power under this trust agreement unless the
Beneficiary has requested the Trustee to take or institute that action,
suit or proceeding and furnished the Trustee with the funds, security or
indemnity referred to in section 6.6 and the Trustee has failed to act
within a reasonable time after the request. In this case, but not
otherwise, the Beneficiary will be entitled to take proceedings in any
court of competent jurisdiction which the Trustee might have taken; it
being understood and intended that no one or more Beneficiaries will have
any right in any manner to affect, disturb or prejudice the rights
created by this trust agreement by any action, or to enforce any right
under this trust agreement or the Voting Rights, the Exchange Rights or
the Automatic Exchange Rights, except subject to the conditions and in
the manner provided in this trust agreement, and that all powers and
trusts under this trust agreement will be exercised and all proceedings
at law will be instituted, had and maintained by the Trustee, except only
as provided in this trust agreement, and in any event for the equal
benefit of all Beneficiaries.

6.8.    Reliance Upon Declarations

        The Trustee will be fully protected and will not be considered to
be in contravention of any its rights, powers, duties and authorities
under this trust agreement if, when required, it acts and relies in good
faith upon statutory declarations, certificates, opinions, Lists, mailing
labels, reports or other papers or documents  furnished pursuant to the
provisions of this trust agreement or required by the Trustee to be
furnished to it in the exercise of its rights, powers, duties and
authorities under this trust agreement if those statutory declarations,
certificates, opinions, Lists, mailing labels, reports or other papers or
documents comply with the provisions of section 6.9, if applicable, and
with any other applicable provisions of this trust agreement.  The
Trustee may rely upon any certificate, opinion, List, report or other

agreement relating to any action or step required or permitted to be
taken by Rational and/or Acquisition Sub or the Trustee under this trust
agreement or as a result of any obligation imposed under this trust
agreement, including, without limitation, in respect of the Voting Rights
or the Exchange Right or the Automatic Exchange Rights and the taking of
any other action to be taken by the Trustee at the request of or on the
application of Rational and/or Acquisition Sub promptly if and when:

(a) that evidence is required by any other section of this trust
agreement to be furnished to the Trustee in accordance with
the terms of this section 6.9; or

(b) the Trustee, in the exercise of its rights, powers, duties
and authorities under this trust agreement, gives Rational
and/or Acquisition Sub written notice requiring it to furnish
that evidence in relation to any particular action or

        The evidence will consist of an Officer's Certificate of Rational
and/or Acquisition Sub or a statutory declaration or a certificate made

condition has been complied with in accordance with the terms of this
trust agreement.

        Whenever the evidence relates to a matter other than the Voting
Rights or the Exchange Right or the Automatic Exchange Rights or the
taking of any other action to be taken by the Trustee at the request or
on the application of Rational and/or Acquisition Sub, and except as
otherwise specifically provided in this trust agreement, the evidence may
consist of a report or opinion of any solicitor, attorney, auditor,
accountant, appraiser, valuer, engineer or other expert or any other
person whose qualifications give authority to a statement made by the
person, provided that if the report or opinion is furnished by a
director, officer or employee of Rational and/or Acquisition Sub it will
be in the form of an Officer's Certificate or a statutory declaration.

        Each statutory declaration, Officer's Certificate, opinion or
report furnished to the Trustee as evidence of compliance with a
condition provided for in this trust agreement will include a statement
by the person giving the evidence:

(a) declaring that the person has read and understands the
provisions of this trust agreement relating to the condition
in question;

investigation upon which the person based the statutory
declaration, certificate, statement or opinion; and

investigations as the person believes is necessary to enable
the person to make the statements or give the opinions
contained or expressed.

6.10.   Experts, Advisers and Agents

        The Trustee may:

(a) act and rely on the opinion or advice of or information
obtained from or prepared by any solicitor, attorney,
auditor, accountant, appraiser, valuer, engineer or other
expert, whether retained by the Trustee or by Rational and/or
Acquisition Sub or otherwise, and may retain or employ any
assistant as may be necessary to the proper discharge of its
powers and duties and determination of its rights under this
trust agreement and may pay proper and reasonable
compensation for any legal and other advice or assistance
referred to above; and

(b) retain or employ any agent and other assistant as it may
reasonably require for the proper determination and discharge
of its powers and duties under this trust agreement, and may
pay reasonable remuneration for all services performed for it
(and will be entitled to receive reasonable remuneration for
all services performed by it) in the discharge of the trusts
of this trust agreement and compensation for all
disbursements, costs and expenses made or incurred by it in
the discharge of its duties under this trust agreement and in
the management of the Trust.

6.11.   Investment of Moneys Held by Trustee

        Unless otherwise provided in this trust agreement, any moneys held
by or on behalf of the Trustee which under the terms of this trust
agreement may or ought to be invested or which may be on deposit with the
Trustee or which may be in the hands of the Trustee may be invested and
reinvested in the name or under the control of the Trustee in securities
stated to mature within two years after their purchase by the Trustee,
and the Trustee will so invest those moneys on the written direction of
Acquisition Sub.  Pending the investment of any moneys as provided above,
those moneys may be deposited in the name of the Trustee in any bank in
the United States of America or, with the consent of Acquisition Sub, in
the deposit department of the Trustee or any other chartered bank, loan
or trust company authorized to accept deposits under the laws of the
United States of America or any state at the rate of interest then
current on similar deposits.

6.12.   Trustee Not Required to Give Security

        The Trustee will not be required to give any bond or security in
respect of the execution of the trusts, rights, duties, powers and
authorities of this trust agreement or otherwise in respect of the
premises.

6.13.   Trustee Not Bound to Act on Request

        Except as otherwise specifically provided in this trust agreement,
the Trustee will not be bound to act in accordance with any direction or
request of Rational and/or Acquisition Sub or of the directors of those
companies until a duly authenticated copy of the instrument or resolution
containing that direction or request has been delivered to the Trustee
and the Trustee has received such reasonable security or indemnity as it
may request in accordance with the requested action, and the Trustee will
be empowered to act and rely upon any copy purporting to be authenticated
and believed by the Trustee to be genuine.

6.14.   Authority to Carry on Business

        The Trustee represents to Rational and Acquisition Sub that at the
date of execution and delivery by it of this trust agreement it is
authorized to carry on the business of a trust company in the United
States of America but if, notwithstanding the provisions of this
section 6.14, it ceases to be so authorized to carry on business, it is
the intention of the parties that the validity and enforceability of this
trust agreement and the Voting Rights, the Exchange Right and the
Automatic Exchange Rights will not be affected in any manner by reason
only of that event, and the Trustee will, within 90 days after ceasing to
be authorized to carry on the business of a trust company in the United
States of America, either become so authorized or resign in the manner
and with the effect specified in Article 9.

6.15.   Conflicting Claims

        If conflicting claims or demands are made or asserted with respect
to any interest of any Beneficiary in any Exchangeable Shares, including
any disagreement between the heirs, representatives, successors or
assigns succeeding to all or any part of the interest of any Beneficiary
in any Exchangeable Shares, resulting in conflicting claims or demands
being made in connection with that interest, then the Trustee will be
entitled, at its sole discretion, to refuse to recognize or to comply
with any of those claims or demands. In so refusing, the Trustee may
elect not to exercise any Voting Rights, Exchange Rights or Automatic
Exchange Rights subject to those conflicting claims or demands and, in so
doing, the Trustee will not be or become liable to any person on account
of that election or its failure or refusal to comply with any of those
conflicting claims or demands. The Trustee will be entitled to continue
to refrain from acting and to refuse to act until:

(a) the rights of all adverse claimants with respect to the
Voting Rights, Exchange Right or Automatic Exchange Rights
subject to those conflicting claims or demands have been
adjudicated by a final judgment of a court of competent
jurisdiction and all rights of appeal have expired; or

(b) all differences with respect to the Voting Rights, Exchange
Right or Automatic Exchange Rights subject to those
conflicting claims or demands have been conclusively settled
by a valid written agreement binding on all adverse
claimants, and the Trustee has been furnished with an
executed copy of that agreement certified to be in full force
and effect.

        If the Trustee elects to recognize any claim or comply with any
demand made by any adverse claimant, it may in its discretion require
that claimant to furnish a surety bond or other security satisfactory to
the Trustee as it deems appropriate to fully indemnify it as between all
conflicting claims or demands.

6.16.   Acceptance of Trust

        The Trustee hereby accepts the Trust created and provided for by
and in this trust agreement and agrees to perform upon the terms and
conditions set out in this trust agreement and to hold all rights,
privileges and benefits conferred by this trust agreement in trust for
the various persons who will from time to time be Beneficiaries, subject
to all the terms and conditions set out in this trust agreement.

ARTICLE 7.

COMPENSATION

7.1.    Fees and Expenses of the Trustee

        Rational and Acquisition Sub jointly and severally agree to pay the
Trustee reasonable compensation for all of the services rendered by it
under this trust agreement and will reimburse the Trustee for all
reasonable expenses (including but not limited to reasonable legal fees
and expenses, taxes other than taxes based on the net income of the
Trustee, compensation paid to experts and advisers, and travel expenses)
and disbursements, including the cost and expense of any suit or
litigation of any character and any proceedings before any governmental
agency reasonably incurred by the Trustee in connection with its duties
under this trust agreement; provided that Rational and Acquisition Sub
will have no obligation to reimburse the Trustee for any expenses or
disbursements paid, incurred or suffered by the Trustee in any suit or
litigation in which the Trustee is determined to have acted in bad faith
or with negligence, recklessness or wilful misconduct.

ARTICLE 8.

INDEMNIFICATION AND LIMITATION OF LIABILITY

8.1.    Indemnification of the Trustee

        Rational and Acquisition Sub jointly and severally agree to
indemnify and hold harmless the Trustee and each of its directors,
officers, employees and agents appointed and acting in accordance with
this trust agreement (collectively, the "Indemnified Parties") against
all claims, losses, liabilities, damages, reasonable costs, penalties,
fines and reasonable expenses (including reasonable fees and expenses of
the Trustee's legal counsel) which, without fraud, negligence,
recklessness, wilful misconduct or bad faith on the part of the
Indemnified Party, may be paid, incurred or suffered by the Indemnified
Party by reason or as a result of the Trustee's acceptance or
administration of the Trust, its compliance with its duties set out in
this trust agreement, or any written or oral instruction (to be confirmed
in writing) delivered to the Trustee by Rational or Acquisition Sub
pursuant to this trust agreement.

        The Trustee will notify Rational and Acquisition Sub of the written
assertion of a claim or of any action commenced against the Indemnified
Parties, promptly after any of the Indemnified Parties has received any
written assertion of a claim or has been served with a summons or other
first legal process giving information as to the nature and basis of the
claim. Subject to (ii) below, Rational and Acquisition Sub will be
entitled to participate at their own expense in the defence and, if
Rational and Acquisition Sub so elect at any time after receipt of the
notice, either of them may assume the defence of any suit brought to
enforce any claim. The Trustee has the right to employ separate counsel
in any suit and participate in the defence of the suit but the fees and
expenses of that counsel will be at the expense of the Trustee unless:
(i) the employment of that counsel has been authorized by Rational or
Acquisition Sub, which authorization will not be unreasonably withheld;
or (ii) the named parties to any suit include both the Trustee and
Rational or Acquisition Sub and the Trustee has been advised by counsel
acceptable to Rational or Acquisition Sub that there may be one or more
legal defences available to the Trustee that are different from or in
addition to those available to Rational or Acquisition Sub and that, in
the judgment of that counsel, would present a conflict of interest were a
joint representation to be undertaken (in which case Rational and
Acquisition Sub will not have the right to assume the defence of that
suit on behalf of the Trustee but will be liable to pay the reasonable
fees and expenses of counsel for the Trustee).  This indemnity will
survive the resignation or removal of the Trustee and the termination of
the Trust.

8.2.    Limitation of Liability

        The Trustee will not be held liable for any loss which may occur by
reason of depreciation of the value of any part of the Trust Estate or
any loss incurred on any investment of funds pursuant to this trust
agreement, except to the extent that the loss is attributable to the
fraud, negligence, recklessness, wilful misconduct or bad faith on the
part of the Trustee.

ARTICLE 9.

CHANGE OF TRUSTEE

9.1.    Resignation

        The Trustee, or any trustee later appointed, may at any time resign
by giving written notice of the resignation to Rational and Acquisition
Sub specifying the date on which it desires to resign, provided that the
notice is not given less than one month before the desired resignation
date, unless Rational and Acquisition Sub otherwise agree, and provided
further that the resignation will not take effect until the date of the
appointment of a successor trustee and the acceptance of that appointment
by the successor trustee.  Upon receiving a notice of resignation,
Rational and Acquisition Sub will promptly appoint a successor trustee by
written instrument in duplicate, one copy of which will be delivered to
the resigning trustee and one copy to the successor trustee.  Failing
appointment of a successor trustee by Rational and Acquisition Sub, a
successor trustee may be appointed by an order of a court of competent
jurisdiction upon application of one or more parties to this trust
agreement.  Should the retiring trustee apply for the appointment of a
successor trustee by an order of the Ontario Superior of Justice it will
be at the joint and several expense of Rational and Acquisition Sub.

9.2.    Removal

        The Trustee, or any trustee later appointed, may (provided a
successor trustee is appointed) be removed at any time on not less than
30 days' prior notice by written instrument executed by Rational and
Acquisition Sub, in duplicate, one copy of which will be delivered to the
trustee so removed and one copy to the successor trustee.

9.3.    Successor Trustee

        Any successor trustee appointed as provided under this trust
agreement will execute, acknowledge and deliver to Rational and
Acquisition Sub and to its predecessor trustee an instrument accepting
the appointment. Upon that acceptance, the resignation or removal of the
predecessor trustee will become effective and the successor trustee,
without any further act, deed or conveyance, will become vested with all
the rights, powers, duties and obligations of its predecessor under this
trust agreement, with the like effect as if originally named as trustee
in this trust agreement. However, on the written request of Rational and
Acquisition Sub or of the successor trustee, the trustee ceasing to act
will, upon payment of any amounts then due it pursuant to the provisions
of this trust agreement, execute and deliver an instrument transferring
to the successor trustee all the rights and powers of the trustee so
ceasing to act. Upon the request of any successor trustee, Rational,
Acquisition Sub and the predecessor trustee will execute any and all
instruments in writing for more fully and certainly vesting in and
confirming to the successor trustee all rights and powers.

9.4.    Notice of Successor Trustee

        Upon acceptance of appointment by a successor trustee as provided
in this trust agreement, Rational and Acquisition Sub will cause to be
mailed notice of the succession of the trustee under this trust agreement
to each Beneficiary specified in a List. If Rational or Acquisition Sub
fail to cause this notice to be mailed within 10 days after acceptance of
appointment by the successor trustee, the successor trustee will cause
the notice to be mailed at the expense of Rational and Acquisition Sub.

ARTICLE 10.

RATIONAL SUCCESSORS

10.1.   Certain Requirements in Respect of Combination, etc.

        Rational will not consummate any transaction (whether by way of
reconstruction, reorganization, consolidation, merger, transfer, sale,
lease or otherwise) whereby all or substantially all of its undertaking,
property and assets would become the property of any other person or, in
the case of a merger, of the continuing corporation resulting from the
merger unless, but may do so if:

(a) the other person or continuing corporation (the "Rational
Successor"), by operation of law, becomes, without more,

COVENANTS OF RATIONAL AND ACQUISITION SUB

2.1.    Covenants Regarding Exchangeable Shares
So long as any Exchangeable Shares not owned by Rational or its
Affiliates are outstanding, Rational will:

(a) not declare or pay any dividend on the Rational Common Shares
unless (i) Acquisition Sub will (w) simultaneously declare or
pay, as the case may be, an equivalent dividend (as provided
for in the Share Provisions) on the Exchangeable Shares (an
"Equivalent Dividend"), and (x) have sufficient money or
other assets or authorized but unissued securities available
to enable the due declaration and the due and punctual
payment, in accordance with applicable law, of any Equivalent
Dividend, or (ii) Acquisition Sub will (y) subdivide the
Exchangeable Shares in lieu of a stock dividend thereon (as
provided for in the Share Provisions) (an "Equivalent Stock
Subdivision"), and (z) have sufficient authorized but
unissued securities available to enable the Equivalent Stock
Subdivision;

(b) advise Acquisition Sub sufficiently in advance of the
declaration by Rational of any dividend on Rational Common
Shares and take any other actions as are reasonably
necessary, in co-operation with Acquisition Sub, to ensure
that (i) the respective declaration date, record date and
payment date for an Equivalent Dividend are the same as the
declaration date, record date and payment date for the
corresponding dividend on the Rational Common Shares or, (ii)
the record date and effective date for an Equivalent Stock
Subdivision are the same as the record date and payment date
for the corresponding stock dividend on the Rational Common
Shares;

(c) ensure that the record date for any dividend declared on
Rational Common Shares is not less than 10 Business Days
after the declaration date of that dividend;

(d) take all actions and do all things as are reasonably
necessary or desirable to enable and permit Acquisition Sub,
in accordance with applicable law, to pay and otherwise
perform its obligations with respect to the satisfaction of
the Liquidation Amount, the Retraction Price or the
Redemption Price in respect of each issued and outstanding
Exchangeable Share upon the liquidation, dissolution or
winding-up of Acquisition Sub, the delivery of a Retraction
Request by a holder of Exchangeable Shares or a redemption of
Exchangeable Shares by Acquisition Sub, as the case may be,
including without limitation all actions and all things as
are necessary or desirable to enable and permit Acquisition
Sub to cause to be delivered Rational Common Shares to the
holders of Exchangeable Shares in accordance with Article 5,
6 or 7, as the case may be, of the Share Provisions;

Right, including without limitation all actions and all
things as are necessary or desirable to enable and permit
Holding ULC to cause to be delivered Rational Common Shares
to the holders of Exchangeable Shares in accordance with the
provisions of the Liquidation Call Right, the Retraction Call
Right or the Redemption Call Right, as the case may be; and

(f) if a holder of Exchangeable Shares becomes a "specified
financial institution" (as that term is defined in the Income
Tax Act (Canada)) or does not deal at arm's length with
Acquisition Sub or otherwise requests Holding ULC to acquire
the Exchangeable Shares, take all actions and do all things
as are reasonably necessary or desirable to cause Holding ULC
to exercise the Retraction Call Right if requested to do so
by that holder of Exchangeable Shares making a Retraction
Request.

2.2.    Segregation of Funds

Rational will cause Acquisition Sub to deposit a sufficient amount
of funds in a separate account of Acquisition Sub and segregate a
sufficient amount of other assets and property as is necessary to enable
Acquisition Sub to pay dividends when due and to pay or otherwise
satisfy its respective obligations under Article 5, 6 or 7 of the Share
Provisions, as applicable.

2.3.    Reservation of Rational Common Shares

Rational hereby represents, warrants and covenants in favour of
Acquisition Sub and Holding ULC that Rational has issued to the Trustee
pursuant to the Voting and Exchange Trust Agreement a number of Rational
Common Shares equal to the number of Exchangeable Shares issued pursuant
to the Plan of Arrangement and will, at all times while any Exchangeable
Shares (other than Exchangeable Shares held by Rational or its
Affiliates) are outstanding, keep available, free from pre-emptive and
other rights, out of its authorized and unissued capital stock or issue
to the Trustee, as the case may be, that number of Rational Common
Shares (or other shares or securities into which Rational Common Shares
may be reclassified or changed as contemplated by section 2.7) as are
now and may later be required to enable and permit Holding ULC to meet
its obligations under the Voting and Exchange Trust Agreement, under
each of the Liquidation Call Right, the Retraction Call Right and the
Redemption Call Right and under any other security or commitment
pursuant to which Rational may now or later be required to issue or
deliver Rational Common Shares and to enable and permit Acquisition Sub
to meet its obligations under this Agreement and under the Share
Provisions.

2.4.    Notification of Certain Events

To assist Rational to comply with its obligations under this
Agreement and to permit Holding ULC to exercise the Liquidation Call
Right, the Retraction Call Right and the Redemption Call Right and to
comply with its obligations under this Agreement, Acquisition Sub will
notify Rational and Holding ULC of each of the following events at the
time set out below:

(a) in the event of any determination by the Board of Directors
of Acquisition Sub to institute voluntary liquidation,
dissolution or winding-up proceedings with respect to
Acquisition Sub or to effect any other distribution of the
assets of Acquisition Sub among its shareholders for the
purpose of winding up its affairs, at least 60 days prior to
the proposed effective date of that liquidation, dissolution,
winding-up or other distribution;

(b) promptly, upon the earlier of receipt by Acquisition Sub of
notice of and Acquisition Sub otherwise becoming aware of any
threatened or instituted claim, suit, petition or other
proceedings with respect to the involuntary liquidation,
dissolution or winding-up of Acquisition Sub or to effect any
other distribution of the assets of Acquisition Sub among its
shareholders for the purpose of winding up its affairs;

of any Exchangeable Shares or rights to acquire Exchangeable
Shares (other than the issuance of Exchangeable Shares and
rights to acquire Exchangeable Shares in exchange for
outstanding Class B Non-Voting Preference Shares pursuant to
the Plan of Arrangement).

2.5.    Delivery of Rational Common Shares to Acquisition Sub and Holding
ULC

In furtherance of its obligations under sections 2.1(d) and (e),
upon notice from Acquisition Sub or Holding ULC of any event that
requires Acquisition Sub or Holding ULC to cause to be delivered
Rational Common Shares to any holder of Exchangeable Shares, Rational
will promptly cause to be delivered to Acquisition Sub or Holding ULC
from the Deposited Shares the requisite number of Rational Common Shares
to be received by, and issued to or to the order of, the former holder
of the surrendered Exchangeable Shares, as Acquisition Sub or Holding
ULC directs.  All Deposited Shares will be duly authorized and validly
issued as fully paid and non-assessable and will be free and clear of
any lien, claim or encumbrance.  In consideration of the issuance and
delivery of each Rational Common Share, Acquisition Sub or Holding ULC
will issue to Rational, or as Rational directs, common shares of
Acquisition Sub or Holding ULC having equivalent value.

2.6.    Qualification of Rational Common Shares

If any Rational Common Shares (or other shares or securities into
which Rational Common Shares may be reclassified or changed as
contemplated by section 2.7) to be issued, transferred and/or delivered
under this Agreement require registration or qualification with or
approval of or the filing of any document, including any prospectus or
similar document or the taking of any proceeding with or the obtaining
of any order, ruling or consent from any governmental or regulatory
authority (i) under the Canadian provincial securities or other law or
regulation or pursuant to the rules and regulations of any securities or
other regulatory authority applicable to holders who are resident in the
provinces of Ontario or Quebec or (ii) under any United States federal
or state securities or other law or regulation or pursuant to the rules
and regulations of any United States securities or other regulatory
authority, or the fulfilment of any other United States legal
requirement or Canadian legal requirement applicable to holders who are
resident in the provinces of Ontario or Quebec before those shares (or
those other shares or securities) may be issued by Rational and
delivered by Rational at the direction of Acquisition Sub or Holding ULC
to the holder of surrendered Exchangeable Shares or in order that those
shares (or those other shares or securities) may be freely traded
thereafter through the facilities of a stock exchange or market in the
United States or through NASDAQ provided that first trade is made in
accordance with the rules of the stock exchange or market upon which the
trade is made or the rules of NASDAQ in accordance with all laws
applicable to that stock exchange or market or applicable to NASDAQ
(other than any restrictions of general application on transfer by
reason of a holder being a "control person" for purposes of Canadian
provincial securities law or an "affiliate" of Rational for purposes of
United States federal or state securities law), Rational will in good
faith expeditiously take all actions and do all things as are necessary
or desirable to cause those Rational Common Shares (or those other
shares or securities) to be and remain duly registered, qualified or
approved under United States and/or Canadian law, as the case may be.
Rational will in good faith expeditiously take all actions and do all
things as are reasonably necessary or desirable to cause all Rational
Common Shares (or those other shares or securities) to be delivered
under this Agreement to be listed, quoted or posted for trading on all
stock exchanges and quotation systems on which outstanding Rational
Common Shares (or those other shares or securities) have been listed by
Rational and remain listed and are quoted or posted for trading at that
time.

2.7.    Economic Equivalence

(a) Rational will not without prior approval of Acquisition Sub and the

prior approval of the holders of the Exchangeable Shares given in
accordance with section 11.2 of the Share Provisions:

(i) issue or distribute Rational Common Shares (or
securities exchangeable for or convertible into or
carrying rights to acquire Rational Common Shares) to
the holders of all or substantially all of the then
outstanding Rational Common Shares by way of stock
dividend or other distribution, other than an issue of
Rational Common Shares (or securities exchangeable for
or convertible into or carrying rights to acquire
Rational Common Shares) to holders of Rational Common
Shares who exercise an option to receive dividends in
Rational Common Shares (or securities exchangeable for
or convertible into or carrying rights to acquire
Rational Common Shares) in lieu of receiving cash
dividends; or

(ii) issue or distribute rights, options or warrants to the
holders of all or substantially all of the then
outstanding Rational Common Shares entitling them to
subscribe for or to purchase Rational Common Shares (or
securities exchangeable for or convertible into or
carrying rights to acquire Rational Common Shares); or

(iii) issue or distribute to the holders of all or
substantially all of the then outstanding Rational
Common Shares (A) shares or securities of Rational of
any class other than Rational Common Shares (other than
shares convertible into or exchangeable for or carrying
rights to acquire Rational Common Shares), (B) rights,
options or warrants other than those referred to in
section 2.7(a)(ii) above, (C) evidences of indebtedness
of Rational or (D) assets of Rational,
 unless the economic equivalent on a per share basis of those rights,
options, securities, shares, evidences of indebtedness or other
assets is issued or distributed simultaneously to holders of the
Exchangeable Shares, in which case, for greater certainty, no
approval of the holders of Exchangeable Shares is required other
than those approvals required by applicable law despite the waiver
of those approval rights pursuant to this Agreement; provided that,
for greater certainty, the above restrictions do not apply to any
securities issued or distributed by Rational to give effect to and
to consummate the transactions contemplated by, and in accordance
with, the Acquisition Agreement.

(b) Rational will not without the prior approval of Acquisition Sub
and the prior approval of the holders of the Exchangeable Shares
given in accordance with section 11.2 of the Share Provisions:

(i) subdivide, redivide or change the then outstanding
Rational Common Shares into a greater number of
Rational Common Shares; or

(ii) reduce, combine, consolidate or change the then
outstanding Rational Common Shares into a lesser number
of Rational Common Shares; or

(iii) reclassify or otherwise change Rational Common Shares
or effect an amalgamation, merger, reorganization or
other transaction affecting Rational Common Shares,
 unless the same or an economically equivalent change is simultaneously
made to, or in the rights of the holders of, the Exchangeable
Shares, in which case, for greater certainty, no approval of the
holders of Exchangeable Shares is required.

(c) Rational will ensure that the record date for any event referred to
in section 2.7(a) or 2.6(b) above, or (if no record date is
applicable for the event) the effective date for that event, is not
less than five Business Days after the date on which that event is
declared or announced by Rational (with contemporaneous
notification by Rational to Acquisition Sub).

(d) The Board of Directors of Acquisition Sub will determine, in good
faith and in its sole discretion, economic equivalence for the
purposes of any event referred to in section 2.7(a) or 2.6(b) above
and each determination will be conclusive and binding on Rational.
In making each determination, the following factors will, without
excluding other factors determined by the Board of Directors of
Acquisition Sub to be relevant, be considered by the Board of
Directors of Acquisition Sub:

(i) in the case of any stock dividend or other distribution
payable in Rational Common Shares, the number of those
shares issued in proportion to the number of Rational
Common Shares previously outstanding;

(ii) in the case of the issuance or distribution of any
rights, options or warrants to subscribe for or
purchase Rational Common Shares (or securities
exchangeable for or convertible into or carrying rights
to acquire Rational Common Shares), the relationship
between the exercise price of each right, option or
warrant and the current market value (as determined by
the Board of Directors of Acquisition Sub in the manner
above contemplated) of a Rational Common Share;

(iii) in the case of the issuance or distribution of any
other form of property (including without limitation
any shares or securities of Rational of any class other
than Rational Common Shares, any rights, options or
warrants other than those referred to in
section 2.7(d)(ii) above, any evidences of indebtedness
of Rational or any assets of Rational), the
relationship between the fair market value (as
determined by the Board of Directors of Acquisition Sub
in the manner above contemplated) of property to be
issued or distributed with respect to each outstanding
Rational Common Share and the current market value (as
determined by the Board of Directors of Acquisition Sub
in the manner above contemplated) of a Rational Common
Share;

(iv) in the case of any subdivision, redivision or change of
the then outstanding Rational Common Shares into a
greater number of Rational Common Shares or the
reduction, combination, consolidation or change of the
then outstanding Rational Common Shares into a lesser
number of Rational Common Shares or any amalgamation,
merger, reorganization or other transaction affecting
Rational Common Shares, the effect of the change upon
the then outstanding Rational Common Shares; and

(v) in all cases, the general taxation consequences of the
relevant event to holders of Exchangeable Shares to the
extent that those consequences may differ from the
taxation consequences to holders of Rational Common
Shares as a result of differences between taxation laws
of Canada and the United States (except for any
differing consequences arising as a result of differing
marginal taxation rates and without regard to the
individual circumstances of holders of Exchangeable
Shares).

 For purposes of the foregoing determinations, the current market value
of any security listed and traded or quoted on a securities
exchange will be the average of the closing bid and ask prices of
that security during a period of not less than 20 consecutive
trading days ending not more than three trading days before the
date of determination on the principal securities exchange on which
that security is listed and traded or quoted; provided, however,
that if in the opinion of the Board of Directors of Acquisition Sub
the public distribution or trading activity of that security during
that period does not create a market which reflects the fair market
value of that security, then the current market value will be
determined by the Board of Directors of Acquisition Sub, in good
faith and in its sole discretion, and provided further that the
determination by the Board of Directors of Acquisition Sub will be
conclusive and binding on Rational.

(e) Acquisition Sub agrees that, to the extent required, upon due
notice from Rational, Acquisition Sub will use its best efforts to
take or cause to be taken all steps as may be necessary for the
purposes of ensuring that appropriate dividends are paid or other
distributions are made by Acquisition Sub, or subdivisions,
redivisions or changes are made to the Exchangeable Shares, in
order to implement the required economic equivalence with respect
to the Rational Common Shares and Exchangeable Shares as provided
for in this section 2.7.

2.8.    Tender Offers

In the event that a tender offer, share exchange offer, issuer
bid, take-over bid or similar transaction with respect to Rational
Common Shares (an "Offer") is proposed by Rational or is proposed to
Rational or its shareholders and is recommended by the Board of
Directors of Rational, or is otherwise effected or to be effected with
the consent or approval of the Board of Directors of Rational, and the
Exchangeable Shares are not redeemed by Acquisition Sub or purchased by
Holding ULC pursuant to the Redemption Call Right, Rational will use its
reasonable efforts expeditiously and in good faith to take all actions
and do all things as are necessary or desirable to enable and permit
holders of Exchangeable Shares to participate in the Offer to the same
extent and on an economically equivalent basis as the holders of
Rational Common Shares, without discrimination.  Without limiting the
generality of the foregoing, Rational will use its reasonable efforts
expeditiously and in good faith to ensure that holders of Exchangeable
Shares may participate in all Offers without being required to retract
Exchangeable Shares as against Acquisition Sub (or, if so required, to
ensure that the retraction, will be effective only upon, and will be
conditional upon, the closing of the Offer and only to the extent
necessary to tender or deposit to the Offer).  Nothing in this Agreement
affects the rights of Acquisition Sub to redeem (or Holding ULC to
purchase pursuant to the Redemption Call Right) Exchangeable Shares, as
applicable, in the event of a Rational Control Transaction.

2.9.    Ownership of Outstanding Shares

Without the prior approval of Acquisition Sub and the prior
approval of the holders of the Exchangeable Shares given in accordance
with section 11.2 of the Share Provisions, Rational covenants and agrees
in favour of Acquisition Sub that, as long as any outstanding
Exchangeable Shares are owned by any person or entity other than
Rational or any of its Affiliates, Rational will be and remain the
direct or indirect beneficial and legal owner of all issued and
outstanding securities in the capital of Acquisition Sub and Holding ULC
carrying or entitled to voting rights in any circumstances generally for
the election of directors.

2.10.   Rational and Affiliates Not to Vote Exchangeable Shares

Rational covenants and agrees that it will appoint and cause to be
appointed proxyholders with respect to all Exchangeable Shares held by
it and its Affiliates for the sole purpose of attending each meeting of
holders of Exchangeable Shares in order to be counted as part of the
quorum for each meeting.  Rational further covenants and agrees that it
will not, and will cause its Affiliates not to, exercise any voting
rights which may be exercisable by holders of Exchangeable Shares from
time to time pursuant to the Share Provisions or pursuant to the
provisions of the Business Corporations Act (Ontario) (or any successor
or other corporate statute by which Acquisition Sub may in the future be
governed) with respect to any Exchangeable Shares held by it or by its
Affiliates in respect of any matter considered at any meeting of holders
of Exchangeable Shares.

2.11.   Rule-10b-18 Purchases

For greater certainty, nothing contained in this Agreement,
including without limitation the obligations of Rational contained in
section 2.7, will limit the ability of Rational or Acquisition Sub to
make a "Rule l0b-18 Purchase" of Rational Common Shares pursuant to Rule
10b-18 of the U.S. Securities Exchange Act of 1934, as amended, or any
successor provisions.

ARTICLE 3.

RATIONAL SUCCESSORS

3.1.    Certain Requirements in Respect of Combination, etc.
Rational will not consummate any transaction (whether by way of
reconstruction, reorganization, consolidation, merger, transfer, sale,
lease or otherwise) whereby all or substantially all of its undertaking,
property and assets would become the property of any other person or, in
the case of a merger, of the continuing corporation resulting from the
merger unless, but may do so if:

(a) the other person or continuing corporation (the "Rational
Successor") by operation of law, becomes, without more, bound
by the terms and provisions of this Agreement or, if not so
bound, executes, prior to or contemporaneously with the
consummation of that transaction, an agreement supplemental
to this Agreement and any other instruments (if any) as are
reasonably necessary or advisable to evidence the assumption
by the Rational Successor of liability for all moneys payable
and property deliverable in accordance with this Agreement
and the Plan of Arrangement and the covenant of the Rational
Successor to pay and deliver or cause to be delivered the
same and its Agreement to observe and perform all the
covenants and obligations of Rational under this Agreement;
and

(b) the transaction will be upon the terms and conditions which
substantially preserve and not impair in any material respect
any of the rights, duties, powers and authorities of the
other parties under this Agreement or the holders of
Exchangeable Shares.

3.2.    Vesting of Powers in Successor

Whenever the conditions of section 3.1 have been duly observed and
performed, the parties, if required by section 3.1, will execute and
deliver a supplemental agreement to this Agreement and the Rational
Successor will then possess and from time to time may exercise each and
every right and power of Rational under this Agreement in the name of
Rational or otherwise and any act or proceeding by any provision of this
Agreement required to be done or performed by the Board of Directors of
Rational or any officers of Rational may be done and performed with like
force and effect by the directors or officers of the Rational Successor.

3.3.    Who-ly-Owned Subsidiaries

Nothing in this Agreement is to be construed as preventing the
amalgamation or merger of any wholly-owned direct or indirect subsidiary
of Rational with or into Rational or the winding-up, liquidation or
dissolution of any wholly-owned subsidiary of Rational provided that all
of the assets of that subsidiary are transferred to Rational or another
wholly-owned direct or indirect subsidiary of Rational and the
transactions are expressly permitted by this Article 3.

ARTICLE 4.

GENERAL

4.1.    Term

This Agreement will come into force and be effective as of the
date of this Agreement and will terminate and be of no further force and
effect when no Exchangeable Shares (or securities or rights convertible
into or exchangeable for or carrying rights to acquire Exchangeable
Shares) are held by any person or entity other than Rational and any of
its Affiliates.

4.2.    Changes in Capital of Rational and Acquisition Sub

At all times after the occurrence of any event contemplated
pursuant to sections 2.7 and 2.8, sections 5.3 or 5.4 of the Plan of
Arrangement or otherwise, as a result of which either Rational Common
Shares or the Exchangeable Shares or both are in any way changed, this
Agreement will promptly be amended and modified as necessary in order
that it will apply with full force and effect, mutatis mutandis, to all
new securities into which Rational Common Shares or the Exchangeable
Shares or both are so changed and the parties to this Agreement will
execute and deliver an Agreement in writing giving effect to and
evidencing any necessary amendments and modifications.

4.3.    Severability

If any term or other provision of this Agreement is invalid,
illegal or incapable of being enforced by any rule or law, or public
policy, all other conditions and provisions of this Agreement will
nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated by this Agreement is
not affected in any manner materially adverse to any party.  Upon the
determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties to this Agreement will
negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable
manner to the end that the transactions contemplated by this Agreement
are fulfilled to the fullest extent possible.

4.4.    Amendments, Modifications

This Agreement may not be amended or modified except by an
Agreement in writing executed by Acquisition Sub, Holding ULC and
Rational and approved by the holders of the Exchangeable Shares in

4.5.    Ministerial Amendments

Notwithstanding section 4.4, the parties to this Agreement may in
writing at any time and from time to time, without the approval of the
holders of the Exchangeable Shares, amend or modify this Agreement for
the purposes of:

(a) adding to the covenants of any or all parties provided that
the Board of Directors of Acquisition Sub is of the good
faith opinion that those additions will not be prejudicial to
the rights or interests of the holders of the Exchangeable
Shares;

(b) making any provisions or modifications not inconsistent with
this Agreement as may be necessary or desirable with respect
to matters or questions arising under this Agreement which,
in the good faith opinion of the Board of Directors of
Acquisition Sub, it may be expedient to make, provided that
the  Board of Directors is of the good faith opinion, after
consultation with counsel, that those provisions or
modifications will not be prejudicial to the rights or
interests of the holders of the Exchangeable Shares; or

(c) making any changes in or corrections to this Agreement which,
on the advice of counsel to Acquisition Sub, are required for
the purpose of curing or correcting any ambiguity or defect
or inconsistent provision or clerical omission or mistake or
manifest error, provided that the Boards of Directors of
Acquisition Sub is of the good faith opinion, after
consultation with counsel, that those changes or corrections
will not be prejudicial to the rights or interests of the
holders of the Exchangeable Shares.

4.6.    Meeting to Consider Amendments

Acquisition Sub, at the request of Rational, will call a meeting
or meetings of the holders of the Exchangeable Shares for the purpose of
considering any proposed amendment or modification requiring approval
pursuant to section 4.4.  Any meeting or meetings will be called and

Exhibit D
                  FOUNDERS' ADDITIONAL RESTRICTIONS AGREEMENT

This Founders' Additional Restrictions Agreement ("Agreement") is
made and entered into as of December 14, 1999, between Rational
Software Corporation, a Delaware corporation ("Parent"), and the
undersigned founder ("Founder") of ObjecTime Limited, an Ontario
corporation ("Company").  Capitalized terms used but not otherwise
defined herein shall have the meanings ascribed to them in the
Acquisition Agreement (as defined below).

RECITALS

A.      Concurrently with the execution of this Agreement, Parent,
Company, Rational International, a California corporation and
subsidiary of Parent ("International Corp."), 3037936 Nova Scotia
Company, a Nova Scotia unlimited liability company and indirect
subsidiary of Parent ("Holding ULC"), 1386501 Ontario Limited, an
Ontario corporation and indirect subsidiary of Parent ("Acquisition
Sub"), and 1386503 Ontario Limited, an Ontario corporation and wholly-
owned subsidiary of Acquisition Sub ("Amalco") have entered into an
Agreement and Plan of Acquisition and Arrangement (the "Acquisition
Agreement"), which contemplates that the Company will execute a Plan of
Arrangement in the form attached to the Acquisition Agreement (the
"Plan of Arrangement"), collectively providing for the amalgamation of
Amalco with and into the Company to form New ObjecTime Corporation, an
Ontario corporation ("New ObjecTime").  Pursuant to the Plan of
Arrangement, shares of capital stock of the Company will be converted
into Class A non-voting preference shares of Acquisition Sub
("Exchangeable Shares") or Common Stock of Parent as set forth in the
Acquisition Agreement (the "Arrangement").
B.      Founder is the beneficial owner (as defined in Rule 13d-3
under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) of such number of shares of the outstanding capital stock of the
Company and shares subject to outstanding options as is indicated on
the signature page of this Agreement.
C.      In order to induce Parent to execute the Acquisition
Agreement, Founder agrees to additional restrictions on the release of
Exchangeable Shares to each Founder so as to facilitate consummation of
the Arrangement.  The execution and delivery of this Agreement is a
material condition to Parent's willingness to enter into the
Acquisition Agreement.
NOW, THEREFORE, intending to be legally bound, the parties agree
as follows:
1. Agreement to Additional Restrictions.
1.1 Release of Shares.  Founder agrees that on the last
calendar day of each calendar month after the Closing Date (the
"Monthly Release Date"), the Depositary Agent shall release and forward
to each Founder that number of Exchangeable Shares equal to one forty-
eighty (1/48th) of the total number of shares designated for receipt by
the Founder at the Closing Date.
1.2 Termination of Employment.  Founder agrees that the
receipt of the Exchangeable Shares shall cease in the event that the
Depositary Agent receives a written notice from Parent (the "Blockage
Notice") to the effect that the Founder has been terminated from
employment with the Company with Cause or has resigned Without Good
Reason (as such terms are defined in the Vesting and Release Schedule,
attached hereto as Exhibit A); provided that no such Blockage Notice
may be issued with respect to the account held for:  (a) Ian Engelberg
after the date on which he and Parent mutually agree shall be the date
on which his employment with Parent shall terminate, which date shall
not be later than December 31, 2000; or (b) Garth Gullekson after April
1, 2001, being the mutually agreed upon date on which his employment
with Parent shall terminate.  The release of blocked shares may resume
upon the receipt by the Depositary Agent of a written recision of the
Blockage Notice by Parent.  Until such recision of the Blockage Notice,
the Depositary Agent shall distribute all existing and future Monthly
Release Amounts to Parent.
2. Representations, Warranties and Covenants of the Founder.
Founder hereby represents, warrants and covenants to Parent that
Founder (i) is a party to the Unanimous Founding Shareholders'
Agreement dated January 1, 1995 whereby each Founder agreed to
arrangements making them the primary shareholders and founders of the
Company; and (ii) has full power and authority to make, enter into and
carry out the terms of this Agreement.
3. Additional Documents.  Founder hereby covenants and agrees
to execute and deliver any additional documents necessary, in the
reasonable opinion of Parent or Founder, as the case may be, to carry
out the intent of this Agreement.
4. Consent and Waiver.  Founder hereby gives any consents or
waivers that are reasonably required for the consummation of the
Arrangement under the terms of any agreements to which Founder is a
party or pursuant to any rights Founder may have.
5. Termination.  This Agreement shall terminate and shall have
no further force or effect as of the expiration date, which shall be
the earlier of (i) such time and date as the Acquisition Agreement
shall have been validly terminated pursuant to Section 9 thereof or
(ii) the date which is the fourth anniversary of the Closing Date.
6. Appointment of Agent.  Shareholder agrees to appoint James
McGee as agent and attorney-in-fact for and on behalf of Shareholder
for purposes of Section 10.7 of the Acquisition Agreement.  Shareholder
further agrees that any decision, act, consent or instruction of the
Company Agent (as defined in the Acquisition Agreement), including,
without limitation, any agreement by the Company Agent for and on
behalf of the holders of Company Shares [(as defined in the Acquisition
Agreement)] to any amendments, modifications and waivers of any term,
condition or other agreement set forth in the Acquisition Agreement,
shall constitute a decision of Shareholder for all purposes of and
under the Acquisition Agreement, and that such decision, act, consent
or instruction shall be final, binding and conclusive upon Shareholder
as if made by Shareholder.
7. Miscellaneous.
7.1 Severability.  If any term, provision, covenant or
restriction of this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable, then the remainder
of the terms, provisions, covenants and restrictions of this Agreement
shall remain in full force and effect and shall in no way be affected,
impaired or invalidated.
7.2 Binding Effect and Assignment.  This Agreement and
all of the provisions hereof shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and
permitted assigns, but, except as otherwise specifically provided
herein, either this Agreement nor any of the rights, interests or
obligations of the parties hereto may be assigned by either of the
parties without prior written consent of the other.
7.3 Amendments and Modification.  This Agreement may not
be modified, amended, altered or supplemented except upon the execution
and delivery of a written agreement executed by the parties hereto.
7.4 Specific Performance; Injunctive Relief.  The parties
hereto acknowledge that Parent will be irreparably harmed and that
there will be no adequate remedy at law for a violation of any of the
covenants or agreement of Founder set forth herein.  Therefore, it is
agreed that, in addition to any other remedies that may be available to
Parent upon any such violation, Parent shall have the right to enforce
such covenants and agreements by specific performance, injunctive
relief or by any other means available to Parent at law or in equity.
7.5 Notices.  All notices, requests, claims, demands and
other communications hereunder shall be in writing and sufficient if
delivered in person, by cable, telegram or telex, or sent by mail
(registered or certified mail, postage prepaid, return receipt
requested) or overnight courier (prepaid) to the respective parties as
follows:

Exhibit E

COMPANY AFFILIATE AGREEMENT
THIS COMPANY AFFILIATE AGREEMENT (this "Agreement") is made and
entered into as of December ___, 1999, by and among Rational Software
Corporation, a Delaware corporation ("Parent"), ObjecTime Limited, an
Ontario corporation (the "Company"), and the undersigned shareholder
who may be deemed an affiliate ("Affiliate") of the Company.
Capitalized terms used but not otherwise defined herein shall have the
meanings ascribed to them in the Acquisition Agreement (as defined
below).
RECITALS
A.      The Company and Parent have entered into an Agreement and
Plan of Acquisition and Arrangement (the "Acquisition Agreement") which
contemplates that Parent will acquire control of the Company through a
statutory arrangement involving the exchange of all of the issued and
outstanding shares of the Company, other than shares owned by Parent
(the "Excluded Shares"), for shares of Parent or an indirect subsidiary
of Parent ("Acquisition Sub").  In accordance with Section 182 of the
Business Corporations Act (Ontario), a Plan of Arrangement for the
Company and Acquisition Sub will be filed in order to effect the
Arrangement (the "Plan of Arrangement").  Pursuant to the Arrangement,
all of the issued and outstanding securities of the Company, other than
the Excluded Shares, will ultimately be exchanged for (i) Parent Common
Shares or Exchangeable Shares, which may be exchanged for Parent Common
Shares and (ii) redeemable Preferred Shares of Acquisition Sub which
are redeemable for cash.
B.      Affiliate is the beneficial owner (as defined in Rule 13d-3
under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")), of such number of shares of the outstanding capital stock of
the Company and of such outstanding options convertible into Common
Shares as is indicated on the signature page of this Agreement.
C.      Affiliate has been advised that Affiliate may be deemed to
be an "affiliate" of the Company, as the term "affiliate" is used for
purposes of Rule 144 of the Rules and Regulations (the "Rules and
Regulations") under the Securities Act of 1933, as amended (the
"Securities Act");
D.      Affiliate has been advised that Affiliate may be deemed to
be an "affiliate" of Parent after the Arrangement as the term
"affiliate" is used in Accounting Series Releases 130 and 135, as
amended, although nothing contained herein shall be construed as an
admission by Affiliate that Affiliate is in fact an "affiliate" of
Parent.  Affiliate further understands that the representations,
warranties and agreements set forth herein will be relied upon by
Parent, the Company and their respective counsel and independent
auditors; and
E.      In consideration of the execution of the Acquisition
Agreement by Parent, Affiliate agrees to be bound by this Agreement and
vote the Shares (as defined below) and other such shares of capital
stock of the Company over which Affiliate has voting power so as to
facilitate consummation of the Arrangement.

AGREEMENT
NOW THEREFORE, intending to be legally bound, the parties agree
as follows:
1. Certain Definitions.  Capitalized terms not defined herein
shall have the meanings ascribed to them in the Acquisition Agreement.
For purposes of this Agreement:
(a) "Person" shall mean any (i) individual, (ii)
corporation, limited liability company, partnership or other entity, or
(iii) governmental authority.
(b) "Shares" shall mean:  (i) all securities of the
Company (including all Company Common Shares, Class A Preferred Shares,
Class B Preferred Shares, Class C Preferred Shares, Class 8 Special
Shares and all options to acquire Company Common Shares) owned by
Affiliate as of the date of this Agreement; and (ii) all additional
securities of the Company (including all additional Company Common
Shares, Class A Preferred Shares, Class B Preferred Shares, Class C
Preferred Shares, Class 8 Special Shares and all additional options and
other rights to acquire Company Common Shares) of which Affiliate
acquires ownership during the period from the date of this Agreement
through the Voting Expiration Date.
(c) A Person shall be deemed to have effected a
"Transfer" of a security if such person directly or indirectly:  (i)
sells, pledges, encumbers, grants an option with respect to, transfers
or disposes of such security or any interest in such security; or (ii)
enters into an agreement or commitment providing for the sale of,
pledge or, encumbrance of, grant of an option with respect to, transfer
of or disposition of such security or any interest therein.
(d) "Voting Expiration Date" shall mean the earlier to
occur of (i) such date and time as the Acquisition Agreement shall have
been validly terminated pursuant to Article IX thereof, or (ii) such
date and time as the Arrangement shall become effective in accordance
with the terms and provisions of the Plan of Arrangement.
2. Acknowledgments by Affiliate.  Affiliate acknowledges and
understands that the representations, warranties and covenants by
Affiliate set forth herein will be relied upon by Parent, the Company
and their respective affiliates, counsel and accounting firms, and that
substantial losses and damages may be incurred by these persons if
Affiliate's representations, warranties or covenants are breached.
Affiliate has carefully read this Agreement and the Acquisition
Agreement and has discussed the requirements of this Agreement with
Affiliate's professional advisors, who are qualified to advise
Affiliate with regard to such matters.
3. Beneficial Ownership of Company Capital Stock and Parent
Common Shares.  The Affiliate is the sole record and beneficial owner
of the number of Shares set forth next to its name on the signature
page hereto. The Shares are not subject to any claim, lien, pledge,
charge, security interest or other encumbrance or to any rights of
first refusal of any kind.  There are no options, warrants, calls,
rights, commitments or agreements of any character, written or oral, to
which the Affiliate is party or by which it is bound obligating the
Affiliate to issue, deliver, sell, repurchase or redeem, or cause to be
issued, delivered, sold, repurchased or redeemed, any Shares or
obligating the Affiliate to grant or enter into any such option,
warrant, call, right, commitment or agreement.  The Affiliate has the
sole right to transfer such Shares.  The Shares constitute all shares
of Company capital stock owned, beneficially or of record, by the
Affiliate.  The Shares are not subject to preemptive rights created by
any agreement to which the Affiliate is party.  The Affiliate has not
engaged in any sale or other transfer of the Shares in contemplation of
the Arrangement.
Affiliate does not beneficially own any Parent Common Shares or
any other equity securities of Parent or any options, warrants or other
rights to acquire any equity securities of Parent.
4. Full Power and Authority.  Affiliate has full power and
authority to make, enter into and carry out the terms of this
Agreement.
5. Compliance with Rule 145 and the Securities Act.
(e) Affiliate has been advised that (i) the resale of
Parent Common Shares and Exchangeable Shares issued in connection with
the Arrangement will be subject to restrictions set forth in Rule 145
under the Securities Act (which will not apply if such shares are
otherwise transferred pursuant to an effective registration statement
under the Securities Act or an appropriate exemption from
registration), and (ii) Affiliate may be deemed to be an affiliate of
the Company.  Affiliate accordingly agrees not to sell, transfer or
otherwise dispose of any Parent Common Shares or Exchangeable Shares
issued to Affiliate in connection with the Arrangement or upon exercise
of the Exchangeable Shares unless (i) such sale, transfer or other
disposition is made in conformity with the requirements of Rule 145(d)
promulgated under the Securities Act, (ii) such sale, transfer or other
disposition is made pursuant to an effective registration statement
under the Securities Act or an appropriate exemption from registration,
or (iii) Affiliate delivers to Parent a written opinion of counsel,
reasonably acceptable to Parent in form and substance, or a "no action"
letter from the staff of the Securities and Exchange Commission, that
such sale, transfer or other disposition is otherwise exempt from
registration under the Securities Act.
(f) Parent will give stop transfer instructions to its
transfer agent with respect to any Parent Common Shares or Exchangeable
Shares received by Affiliate pursuant to the Arrangement and there will
be placed on the certificates representing such Parent Common Shares or
Exchangeable Shares, or any substitutions therefor, a legend stating in
substance:

"THE SHARES REPRESENTED BY THIS CERTIFICATE  WERE ISSUED IN A TRANSACTION TO
WHICH RULE  145 APPLIES AND MAY ONLY BE TRANSFERRED IN  CONFORMITY WITH RULE
145(d) OR PURSUANT TO  AN EFFECTIVE REGISTRATION STATEMENT UNDER  THE
SECURITIES ACT OF 1933, AS AMENDED, OR  IN ACCORDANCE WITH A WRITTEN OPINION OF
COUNSEL, REASONABLY ACCEPTABLE TO THE ISSUER  IN FORM AND SUBSTANCE, OR A "NO
ACTION"  LETTER FROM THE STAFF OF THE SECURITIES AND  EXCHANGE COMMISSION, THAT
SUCH TRANSFER IS  EXEMPT FROM REGISTRATION UNDER THE  SECURITIES ACT OF 1933,
AS AMENDED."

The legend set forth above shall be removed (by delivery of a
substitute certificate without such legend) and Parent shall so
instruct its transfer agent, if Affiliate delivers to Parent
(i) satisfactory written evidence that the shares have been sold in
compliance with Rule 145 (in which case, the substitute certificate
will be issued in the name of the transferee), or (ii) an opinion of
counsel, in form and substance reasonably satisfactory to Parent, to
the effect that public sale of the shares by the holder thereof is no
longer subject to Rule 145.
6. Conversion of Shares.  The Affiliate agrees that, to the
extent any of the Shares consist of shares of Class A Preferred Shares,
Class B Preferred Shares, Class C Preferred Shares and Class 8 Special
Shares of the Company, Affiliate shall not exercise any conversion
rights in respect of such Shares prior to the record date fixed by the
Board of Directors of the Company for the determination of shareholders
entitled to vote on the Arrangement.
7. Agreement to Vote Shares.  At every meeting of the
shareholders of the Company called and at every adjournment thereof,
and on every action or approval by written consent of the shareholders
of the Company, Affiliate shall:  (i) cause the Shares to be voted in
favor of approval of the Arrangement; and (ii) not cause the Shares to
be voted against approval of the Arrangement.  Affiliate agrees that
during the period from the date of this Agreement through the Voting
Expiration Date, Affiliate shall not deposit (or permit the deposit of)
any Shares in a voting trust or grant any proxy or enter into any
voting agreement or similar agreement in contravention of the
obligations of Affiliate under this Agreement with respect to any of
the Shares.
8. Proxy Solicitation.  Affiliate will not, and will not
permit any entity under Affiliate's control to:  (i) solicit proxies or
become a "participant" in a "solicitation" (as such terms are defined
in Regulation 14A under the Exchange Act) with respect to an
Acquisition Proposal or otherwise encourage or assist any party in
taking or planning any action that would compete with, restrain or
otherwise serve to interfere with or inhibit the timely consummation of
the Arrangement in accordance with the terms of the Acquisition
Agreement and Plan of Arrangement (other than, in the case of an
Affiliate who is a director of the Company, such actions taken as a
director (and not a shareholder) of the Company in accordance with
Sections 5.7 and 5.8 of the Acquisition Agreement); (ii) initiate a
shareholders' vote or action by consent of the Company shareholders
with respect to an Acquisition Proposal; or (iii) become a member of a
"group" (as such term is used in Section 13(d) of the Exchange Act)
with respect to any voting securities of the Company with respect to an
Acquisition Proposal.
9. Additional Documents.  Affiliate hereby covenants and
agrees to execute and deliver any additional documents necessary or
desirable, in the reasonable opinion of Parent, to carry out the intent
of this Agreement.
10. Consent and Waiver.  Affiliate (not in his or her capacity
as a director or officer of the Company) hereby gives any consents or
waivers that are reasonably required for the consummation of the
Arrangement under the terms of any agreements to which Affiliate is a
party or pursuant to any rights Affiliate may have.
11. Termination.  This Agreement shall be terminated and shall
be of no further force and effect in the event of the termination of
the Acquisition Agreement pursuant to Article 9 of the Acquisition
Agreement.
12. Miscellaneous.
(g) Counterparts.  This Agreement shall be executed in
one or more counterparts, each of which shall be deemed an original,
and all of which together shall constitute one and the same instrument.
(h) Binding Agreement.  This Agreement will inure to the
benefit of and be binding upon and enforceable against the parties and
their successors and assigns, including administrators, executors,
representatives, heirs, legatees and devisees of Affiliate and pledgees
of Affiliate holding any shares of the Company's capital stock as
collateral.
(i) Waiver; Severability.  No waiver by any party hereto
of any condition or of any breach of any provision of this Agreement
shall be effective unless in writing and signed by each party hereto.
In the event that any provision of this Agreement, or the application
of any such provision to any person, entity or set of circumstances,
shall be determined to be invalid, unlawful, void or unenforceable to
any extent, the remainder of this Agreement, and the application of
such provision to persons, entities or circumstances other than those
as to which it is determined to be invalid, unlawful, void or
unenforceable, shall not be impaired or otherwise affected and shall
continue to be valid and enforceable to the fullest extent permitted by
law.
(j) Governing Law.  This Agreement shall be governed by
and construed in accordance with the internal laws of the State of
California without giving effect to any choice or conflict of law
provision or rule (whether of the State of California or any other
jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of California.
(k) Attorneys' Fees. In the event of any legal actions or
proceeding to enforce or interpret the provisions hereof, the
prevailing party shall be entitled to reasonable attorneys' fees,
whether or not the proceeding results in a final judgment.
(l) Effect of Headings. The Section headings herein are
for convenience only and shall not affect the construction or
interpretation of this Agreement.
(m) Third-Party Reliance.  Counsel to and independent
auditors for the parties to the Acquisition Agreement shall be entitled
to rely upon this Affiliate Agreement.
(n) Entire Agreement.  This Agreement, the Acquisition
Agreement and the other agreements referred to in the Acquisition
Agreement set forth the entire understanding of Affiliate and Parent
relating to the subject matter hereof and thereof and supersede all
prior agreements and understandings between Affiliate and Parent
relating to the subject matter hereof and thereof.
(o) Amendments.  This Agreement may not be amended,
modified, altered, or supplemented other than by means of a written
instrument duly executed and delivered on behalf of Parent and the
Affiliate.
(p) Survival.  The representations, warranties, covenants
and other provisions contained in this Agreement shall survive the
Arrangement.
(q) Injunctive Relief.  Each of the parties acknowledge
that (i) the covenants and the restrictions contained in this Agreement
are necessary, fundamental, and required for the protection of Parent
and the Company and to preserve for Parent the benefits of the
Arrangement; (ii) such covenants relate to matters which are of a
special, unique, and extraordinary character that gives each of such
covenants a special, unique, and extraordinary value; and (iii) a
breach of any such covenants or any other provision of this Agreement
will result in irreparable harm and damages to Parent and the Company
which cannot be adequately compensated by a monetary award.
Accordingly, it is expressly agreed that in addition to all other
remedies available at law or in equity, Parent and the Company shall be
entitled to the immediate remedy of a temporary restraining order,
preliminary injunction, or such other form of injunctive or equitable
relief as may be used by any court of competent jurisdiction to
restrain or enjoin any of the parties hereto from breaching any such
covenant or provision or to specifically enforce the provisions hereof.

Exhibit F

VOTING AGREEMENT
This Voting Agreement (the "Agreement") is made and entered into
as of December 14, 1999 by and among Rational Software Corporation, a
Delaware corporation ("Parent"), and the undersigned shareholder and/or
option holder (the "Shareholder") of ObjecTime Limited, an Ontario
corporation (the "Company").  Capitalized terms used but not otherwise
defined herein shall have the meanings ascribed to them  in the
Acquisition Agreement (as defined below).
RECITALS
A.      The Company, Acquisition Sub (as defined below), Amalco (as
defined below) and Parent have entered into an Agreement and Plan of
Acquisition and Arrangement of even date herewith (the "Acquisition
Agreement"), which contemplates that the Company will execute a Plan of
Arrangement in the form attached to the Acquisition Agreement (the
"Plan of Arrangement"), collectively providing for the formation of an
indirect subsidiary of Parent ("Acquisition Sub") which will
incorporate its wholly-owned subsidiary ("Amalco"), which will
amalgamate with and into the Company to form New ObjecTime Corporation,
an Ontario corporation ("New ObjecTime").  Pursuant to the Plan of
Arrangement, all of the issued and outstanding shares of capital stock
of the Company will be converted into (i) exchangeable shares of
Acquisition Sub ("Exchangeable Shares") or Common Shares of Parent and
(ii) cash, as set forth in the Acquisition Agreement (the
"Arrangement");
B.      Shareholder is the beneficial owner (as defined in Rule
13d-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) of such number of shares of the outstanding capital
stock of the Company and shares subject to outstanding options as is
indicated on the signature page of this Agreement; and
C.      In order to induce Parent to execute the Acquisition
Agreement, Shareholder agrees to vote the Shares (as defined below) and
other such shares of capital stock of the Company over which
Shareholder has voting power so as to facilitate consummation of the
Arrangement.  The execution and delivery of this Agreement and of the
attached form of proxy is a material condition to Parent's willingness
to enter into the Acquisition Agreement.
NOW, THEREFORE, intending to be legally bound, the parties agree
as follows:
1. Certain Definitions.  Capitalized terms not defined herein
shall have the meanings ascribed to them in the Acquisition Agreement.
For purposes of this Agreement:
1.1 "Expiration Date" shall mean the earlier to occur of
(i) such date and time as the Acquisition Agreement shall have been
validly terminated pursuant to Section 9 thereof, or (ii) such date and
time as the Arrangement shall become effective in accordance with the
terms and provisions of the Acquisition Agreement.
1.2 "Person" shall mean any (i) individual, (ii)
corporation, limited liability company, partnership or other entity, or
(iii) governmental authority.
1.3 "Shares" shall mean: (i) all equity securities of the
Company (including all shares of Company shares and all Company Options
) beneficially owned by Shareholder as of the date of this Agreement;
and (ii) all additional equity securities of the Company (including all
additional shares of Company Common Stock or Preferred Stock and all
additional options to acquire shares of Company Common Stock or
Preferred Stock) of which Shareholder acquires beneficial ownership
during the period from the date of this Agreement through the
Expiration Date.
1.4 A Person shall be deemed to have effected a
"Transfer" of a security if such person directly or indirectly: (i)
sells, pledges, encumbers, grants an option with respect to, transfers
or disposes of such security or any interest in such security; or (ii)
enters into an agreement or commitment providing for the sale of,
pledge of, encumbrance of, grant of an option with respect to, transfer
of or disposition of such security or any interest therein.
2. Transfer of Shares.
2.1 Transferee of Shares to be Bound by this Agreement.
Shareholder agrees that, during the period from the date of this
Agreement through the Expiration Date, Shareholder shall not cause or
permit any Transfer of any of the Shares to be effected unless such
Transfer is in accordance with any affiliate agreement between
Shareholder and Parent contemplated by the Acquisition Agreement and
each Person to which any of such Shares, or any interest in any of such
Shares, is or may be transferred shall have: (a) executed a counterpart
of this Agreement and a proxy in the form attached hereto as Exhibit A
(with such modifications not involving additional representations,
warranties or covenants as Parent may reasonably request); and (b)
agreed in writing to hold such Shares (or interest in such Shares)
subject to all of the terms and provisions of this Agreement.
2.2 Transfer of Voting Rights.  Shareholder agrees that,
during the period from the date of this Agreement through the
Expiration Date, Shareholder shall not deposit (or permit the deposit
of) any Shares in a voting trust or grant any proxy or enter into any
voting agreement or similar agreement in contravention of the
obligations of Shareholder under this Agreement with respect to any of
the Shares.
3. Conversion of Shares.  The Shareholder agrees that, to the
extent any of the Shares consist of shares of Preferred Stock or
Special Stock of the Company, Shareholder shall not exercise any
conversion rights in respect of such Shares prior to the record date
fixed by the Board of Directors of the Company for the determination of
stockholders entitled to vote on the Merger.
4. Agreement to Vote Shares.  At every meeting of stockholders
of the Company called with respect to any of the following, and at
every adjournment thereof, and on every action or approval by written
consent of stockholders of the Company with respect to any of the
following, Shareholder shall vote the Shares in favor of approval of
the Arrangement, the execution and delivery by the Company of the
Acquisition Agreement and the adoption and approval of the terms
thereof and in favor of each of the other actions contemplated by the
Acquisition Agreement and any action reasonably required in furtherance
hereof and thereof.
5. Non-Solicitation Agreement.  Shareholder covenants and
agrees, prior to the Expiration Date, not to, directly or indirectly,
(i) solicit, initiate or encourage submission of proposals or offers or
engage in negotiations with any persons other than Parent, Acquisition
Sub, or Amalco or take any action intended, designed or reasonably
likely to facilitate the efforts of any persons, other than Parent,
Acquisition Sub and Amalco, relating to (A) the possible acquisition of
the Company (whether by way of merger, purchase of its capital stock,
purchase of assets or otherwise) or any material portion of its capital
stock or assets or (B) any other material transaction (including
without limitation, a joint venture or other similar transaction) (an

the Company to any person in connection with or in response to an
Opposing Proposal or potential Opposing Proposal; (iii) engage in
discussions with any persons with respect to any Opposing Proposal;
(iv) approve, endorse or recommend any Opposing Proposal; or (v) enter
into any letter of intent or other similar document or any contract
contemplating or otherwise relating to any Opposing Proposal.
Shareholder shall immediately cease any existing discussions with any
persons other than Parent and Acquisition Sub that relate to any
Opposing Proposal.  In the event that Shareholder receives from any
third party any offer or indication of interest (whether made in
writing or otherwise) regarding any of the transactions referred to in
the foregoing, then Shareholder shall promptly communicate to Parent
the material terms of each such offer, indication of interest, or
request, including the identity of the third party.
6. Irrevocable Proxy.  Concurrently with the execution of this
Agreement, Shareholder agrees to deliver to Parent a proxy in the form
attached hereto as Exhibit A (the "Proxy"), which shall be irrevocable
to the fullest extent permissible by law, with respect to the Shares.
7. Representations and Warranties of the Shareholder.
Shareholder (i) is the beneficial owner of the shares of Common Stock
of the Company, Preferred Stock of the Company and the options to
purchase shares of Common Stock of the Company indicated on the final
page of this Agreement, free and clear of any liens, claims, options
(other than the call option and the put option, if any, contained in a
Shareholder Agreement between the Shareholder and the Company), rights
of first refusal, co-sale rights, charges or other encumbrances; (ii)
does not beneficially own any securities of the Company other than the
shares of Common Stock of the Company, Preferred Stock of the Company
and options to purchase shares of Common Stock of the Company indicated
on the signature page of this Agreement; and (iii) has full power and
authority to make, enter into and, assuming due execution and delivery
thereof by each other party thereto, carry out the terms of this
Agreement and the Proxy.
8. Additional Documents.  Shareholder hereby covenants and
agrees to execute and deliver any additional documents not involving
additional representations, warranties or covenants necessary or
desirable, in the reasonable opinion of Parent, to carry out the intent
of this Agreement.
9. Consent and Waiver.  Shareholder (not in his capacity as a
director or officer of the Company) hereby gives any consents or
waivers (including waivers of preemptive rights, rights of first
refusal and co-sale rights) that are reasonably required for the
consummation of the Arrangement under the terms of any agreements to
which Shareholder is a party or pursuant to any rights Shareholder may
have.
10. Legending of Shares.  If so requested by Parent,
Shareholder agrees that the Shares shall bear a legend stating that
they are subject to this Agreement and to an irrevocable proxy.
Subject to the terms of Section 2 hereof, Shareholder agrees that
Shareholder will not Transfer the Shares without first having the
aforementioned legend affixed to the certificates representing the
Shares.
11. Termination.  This Agreement shall terminate and shall have
no further force or effect as of the Expiration Date.
12. Miscellaneous.
12.1 Severability.  If any term, provision, covenant or
restriction of this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable, then the remainder
of the terms, provisions, covenants and restrictions of this Agreement
shall remain in full force and effect and shall in no way be affected,
impaired or invalidated.
12.2 Binding Effect and Assignment.  This Agreement and
all of the provisions hereof shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and
permitted assigns, but, except as otherwise specifically provided
herein, neither this Agreement nor any of the rights, interests or
obligations of the parties hereto may be assigned by either of the
parties without prior written consent of the other.
12.3 Amendments and Modification.  This Agreement may not
be modified, amended, altered or supplemented except upon the execution
and delivery of a written agreement executed by the parties hereto.
12.4 Waiver.  No failure on the part of Parent to exercise
any power, right, privilege or remedy under this Agreement, and no
delay on the part of Parent in exercising any power, right, privilege
or remedy under this Agreement, shall operate as a waiver of such
power, right, privilege or remedy; and no single or partial exercise of
any such power, right, privilege or remedy shall preclude any other or
further exercise thereof or of any other power, right, privilege or
remedy.  Parent shall not be deemed to have waived any claim arising
out of this Agreement, or any power, right, privilege or remedy under
this Agreement, unless the waiver of such claim, power, right,
privilege or remedy is expressly set forth in a written instrument duly
executed and delivered on behalf of Parent; and any such waiver shall
not be applicable or have any effect except in the specific instance in
which it is given.
12.5 Specific Performance; Injunctive Relief.  The parties
hereto acknowledge that Parent will be irreparably harmed and that
there will be no adequate remedy at law for a violation of any of the
covenants or agreements of Shareholder set forth herein.  Therefore, it
is agreed that, in addition to any other remedies that may be available
to Parent upon any such violation, Parent shall have the right to
enforce such covenants and agreements by specific performance,
injunctive relief or by any other means available to Parent at law or
in equity.

portion of the Exchangeable Shares and Parent Common Stock upon the
release of such shares from the Escrow Fund (as defined below);
WHEREAS, pursuant to Article X of the Acquisition Agreement, a
copy of which is attached hereto as Annex A ("Article X"), an escrow
fund (the "Escrow Fund") will be established to compensate Rational for

Agreement;
WHEREAS, the Company Agent has been constituted as the agent for
and on behalf of the Shareholders to undertake certain obligations

WHEREAS, Section 2.1 of the Acquisition Agreement provides for
the creation of subaccounts for each shareholder of OTL by the

WHEREAS, Section 2.2.4.5 of the Plan of Arrangement provides that

conditions in addition to those set forth in the Acquisition Agreement
relating to the operation of the Escrow Fund and the Vesting and
Release Schedule; and
WHEREAS, the operation of this agreement has been approved by an
order of the Ontario Superior Court of Justice.
NOW, THEREFORE, the parties hereto, in consideration of the
mutual covenants contained herein, and intending to be legally bound,
hereby agree as follows:
1. Escrow and Escrow Shares.  Pursuant to the Acquisition
Agreement, Acquisition Sub and Rational shall deposit in escrow with
the Depositary Agent, as Depositary Agent, stock certificates
representing the number of  Exchangeable Shares issuable to the
Shareholders set out in Annex C, having a value of approximately
$3,800,000 (collectively, the "Escrow Shares"), which Escrow Shares
shall be registered in the name of the Depositary Agent as Depositary
Agent under this Agreement and will be beneficially owned by the
Shareholders on a pro rata basis.  The Escrow Shares shall be held and
distributed by the Depositary Agent in accordance with the terms and
conditions of Article X and this Agreement.  The type and pro rata
portion of Escrow Shares to be released to the Holder's Account (as
defined below) of each Shareholder at the end of the Half-Time Date (as
defined below) and the Escrow Period is set forth in Annex C attached
hereto.  The remainder of the Exchangeable Shares and Parent Common
Shares issuable to the Shareholders pursuant to the Acquisition
Agreement and not constituting Escrow Shares (the "Restricted Shares")
shall be deposited with the Depositary Agent, who shall establish
subaccounts for each Holder (a "Holder's Account"), and such shares
shall be released by the Depositary Agent on a monthly basis to each
Holder in accordance with the Vesting and Release Schedule.  In the
event that a holder of Restricted Options (as defined below) is
terminated Without Cause by Parent, any Options that were (i) vested at
the time of Closing and (ii) delivered to Parent to be held with
additional restrictions (the "Restricted Options") shall be placed into
such holder's Holder's Account to be held by the Depository Agent and
released pursuant to the Vesting and Release Schedule.
2. Rights and Obligations of the Parties.  The Depositary
Agent shall be entitled to such rights and shall perform such duties of
the Depositary Agent as set forth herein (collectively, the "Duties"),
in accordance with the terms and conditions of this Agreement. As among
themselves, Rational and the Company Agent shall be entitled to their
respective rights and shall perform their respective duties and
obligations as set forth herein and in Article X, in accordance with
the terms hereof and thereof. In the event that the terms of this
Agreement conflict in any way with the provisions of Article X, Article
X shall control.
3. Escrow Period.
(a) The period of time during which the Escrow Fund shall
be in existence (the "Escrow Period") shall commence immediately
following the Closing Date, which shall be set forth in a certificate
of Rational delivered to the Depositary Agent, and shall terminate at
5:00 p.m., California time, on the date which is the second anniversary
of the Closing Date, provided that the Escrow Fund will terminate with
respect to 50% of the Escrow Shares on the first anniversary of the
Closing Date (the "Half-Time Date"); provided, however, that a portion
of the Escrow Shares, which is necessary to satisfy any unsatisfied
claims specified in any Officer's Certificate theretofore delivered to
the Depositary Agent prior to termination of the Half-Time Date or
Escrow Period with respect to facts and circumstances existing prior to
expiration of the Half-Time Date or Escrow Period (a "Claim Notice")
shall remain in the Escrow Fund until such claims have been Resolved.
As used herein, "Resolved" shall mean that the Depositary Agent shall
have received either (i) joint written instruction signed by each of
Rational and the Company Agent, giving instruction to the Depositary
Agent with respect to resolution of a claim specified in a Claim Notice
received by the Depositary Agent, which direction identifies such claim
and provides specific instruction to the Depositary Agent with respect
to the distribution of Escrow Shares in respect thereof, or (ii) a
certificate of either Rational or the Company Agent certifying that a
claim specified in a Claim Notice received by the Depositary Agent has
been resolved by a court of competent jurisdiction, for which a final,
non-appealable order has been issued entitling Rational or the
Shareholders, as specified in such certificate, to the release from
escrow of an amount of Escrow Shares, as specified therein, a copy of
which order is attached thereto.  The period of time during which the
Holder's Accounts shall be in existence shall commence immediately
following the Closing Date and shall terminate at 5:00 p.m., California
time, on the date which is the fourth anniversary of the Closing Date
(the "Restricted Share Escrow Period")
(b) The Restricted Shares shall be released by the
Depositary Agent in accordance with the Vesting and Release Schedule.
4. Duties of Depositary Agent. Depositary Agent shall have the
following duties:
(a) The Depositary Agent shall hold and safeguard the
Restricted Shares and Escrow Shares during the Restricted Share Escrow
Period and Escrow Period, respectively, shall treat such Escrow Shares
in accordance with the terms of this Agreement and not as the property
of Rational or the Shareholders, and shall hold and dispose of the
Escrow Shares only in accordance with the terms hereof.
(b) Promptly following termination of the Half-Time Date
or Escrow Period as set forth in Section 3 hereof, the Depositary Agent
shall transfer to the Holder's Accounts held by the Depository Agent
for the Shareholders listed on Annex C the proper number and type of
Escrow Shares in the Escrow Fund in excess of any amount of such Escrow
Shares required to be transferred to Parent to satisfy any unsatisfied
claims specified in any Officer's Certificate theretofore delivered to
the Depositary Agent prior to termination of the Half-Time Date or
Escrow Period with respect to facts and circumstances existing prior to
expiration of the Half-Time Date or Escrow Period. In determining or
making any allocation or distribution of Escrow Shares, the Depositary
Agent shall apply the per share price certified to the Depositary Agent
by Rational and the Company Agent pursuant to Section 10.4(b) of
Article X (the "Closing Share Price").  If Rational and the Company
Agent fail to provide such certificate to the Depositary Agent on a
timely basis, the Depositary Agent shall have no duty to make any such
distribution (and shall have no duty to determine the amount of
Damages).  As soon as all such claims have been finally resolved
following the Half-Time Date or Escrow Period, the Depositary Agent
shall transfer to the Holder's Accounts held by the Depository Agent
for the Shareholders the Escrow Shares remaining in the Escrow Fund to
be released in accordance with the Vesting and Release Schedule.  In
each distribution of Escrow Shares, each Holder's Account held for the
Shareholders shall receive that percentage of the type of Escrow Shares
indicated as owned by such Shareholder on Annex C hereto (and cash in
lieu payments when appropriate), which is the product of (x) the total
number of such type of Escrow Shares in the Escrow Fund and available
for distribution and (y) the percentage interest of such type of Escrow
Shares set forth opposite the name of each such Shareholder on Annex B
hereto, with half of such shares to be transferred on each of the Half-
Time Date and the termination of the Escrow Period.  Such distributions
shall occur promptly following the Half-Time Date and the termination
of the Escrow Period.
(c) In making any distribution of Escrow Shares pursuant
to the terms of this Section 4 or Section 5, the Depositary Agent shall
round down (if necessary) to a whole number of shares and pay to each
Shareholder, as appropriate, from funds provided by Rational, cash in
lieu of the fractional interests not distributed equal to the product
of (x) such fractional amount and (y) the Closing Share Price. Any
shares for which Rational has provided cash in lieu of fractional
interests shall be distributed to Rational, which shall be deemed to
have purchased them.
(d) As used herein, "Officer's Certificate" shall mean an
"Officer's Certificate" as defined in Section 10.4(a) of Article X
setting forth the specific amount of each claim or claim addressed
therein.
5. Distribution.  Any cash dividends, dividends payable in
securities or other distributions of any kind shall be promptly
distributed by the Depositary Agent to (and for tax reporting purposes
shall be allocable to) the Shareholders, as beneficial owners of the
Escrow Shares, at their addresses set forth in a certificate of the
Company Agent in accordance with their percentage interests set forth
in Annex C. Any Exchangeable Shares or shares of Parent Common Stock,
as the case may be, received by the Depositary Agent upon a stock split
made in respect of any such securities in the Escrow Fund shall be
added to the Escrow Fund and become a part thereof.  Any provision
hereof or of Article X shall be adjusted to appropriately reflect any
stock split or reverse stock split.
6. Exculpatory Provisions; Indemnification.
(a) The Depositary Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, as are
set forth in Article X and as are set forth in any additional written
escrow instructions, which instructions shall not expose Depositary
Agent to any liability additional to that assumed by Depositary Agent
hereunder or under Article X, which the Depositary Agent may receive
after the date of this Agreement which are signed by an officer of
Rational and the Company Agent. The Depositary Agent may rely and shall
be protected in relying or refraining from acting on any instrument
reasonably believed to be genuine and to have been signed or presented
by the proper party or parties. The Depositary Agent shall not be
liable for any act done or omitted hereunder as Depositary Agent while
acting in good faith and in the exercise of reasonable judgment, and
any act done or omitted pursuant to the advice of counsel shall be
conclusive evidence of such good faith.
(b) The Depositary Agent is hereby expressly authorized
to comply with and obey orders, judgments or decrees of any court of
law, notwithstanding any notices, warnings or other communications from
any party or any other person to the contrary. In case the Depositary
Agent obeys or complies with any such order, judgment or decree of any
court, the Depositary Agent shall not be liable to any of the parties
hereto or to any other person by reason of such compliance,
notwithstanding any such order, judgment or decree being subsequently
reversed, modified, annulled, set aside, vacated or found to have been
entered without jurisdiction.
(c) The Depositary Agent shall not be liable in any
respect on account of the identity, authority or rights of the parties
executing or delivering or purporting to execute or deliver this
Agreement or any documents or papers deposited or called for hereunder.
The Depositary Agent shall not be responsible for the genuineness,
validity, enforceability or sufficiency of title to any Restricted
Shares or Escrow Shares or other property delivered it hereunder.
(d) In performing any duties under or in connection with
this Agreement, the Depositary Agent shall not be liable to any party
for damages, losses, or expenses, except for gross negligence or
willful misconduct on the part of the Depositary Agent. The Depositary
Agent shall not incur any such liability for (A) any act or failure to
act made or omitted in good faith, or (B) any action taken or omitted
in reliance upon any instrument, including any written statement or
affidavit provided for in this Agreement that the Depositary Agent
shall in good faith believe to be genuine, nor will the Depositary
Agent be liable or responsible for forgeries, fraud, impersonations, or
determining the scope of any representative authority. In addition, the
Depositary Agent may consult with the legal counsel in connection with
Depositary Agent's duties under or in connection with this Agreement
and shall be fully protected in any act taken, suffered, or permitted
by him/her in good faith in accordance with the advice of counsel. The
Depositary Agent is not responsible for determining and verifying the
authority of any person acting or purporting to act on behalf of any
party to this Agreement. In no event shall the Depositary Agent be
liable for special, consequential or indirect damages.
(e) If any controversy arises between the parties to this
Agreement, or with any other party, concerning the subject matter of
this Agreement, its terms or conditions, the Depositary Agent will not
be required to determine the controversy or to take any action
regarding it. The Depositary Agent may hold all documents and
Restricted Shares and Escrow Shares and may wait for settlement of any
such controversy by final appropriate legal proceedings or other means.
(f) Rational and its successors and assigns agrees to
indemnify and hold Depositary Agent harmless against any and all
losses, claims, damages, liabilities, and expenses, including
reasonable costs of investigation, counsel fees, and disbursements that
may be imposed on Depositary Agent or incurred by Depositary Agent in
connection with the performance of his/her duties under or in
connection with this Agreement, including but not limited to any
litigation arising from or in connection with this Agreement or
involving its subject matter.
(g) Rational agrees to assume any and all obligations
imposed now or hereafter by any applicable tax law with respect to the
distribution of Restricted Shares and Escrow Shares under this
Agreement, and to indemnify and hold the Depositary Agent harmless from
and against any taxes, additions for late payment, interest, penalties
and other expenses, that may be assessed against the Depositary Agent
on any such payment or other activities under this Agreement. Rational
and the Company Agent undertake to instruct the Depositary Agent in
writing with respect to the Depositary Agent's responsibility for
withholding and other taxes, assessments or other governmental charges,
certifications and governmental reporting in connection with its acting
as Depositary Agent under this Agreement.  Rational agrees to indemnify
and hold the Depositary Agent harmless from any liability on account of
taxes, assessments or other governmental charges, including without
limitation the withholding or deduction or the failure to withhold or
deduct same, and any liability for failure to obtain proper
certifications or to properly report to governmental authorities, to
which the Depositary Agent may be or become subject in connection with
or which arises out of this Agreement, including costs and expenses
(including reasonable legal fees), interest and penalties.
Notwithstanding the foregoing, no distributions will be made unless the
Depositary Agent is supplied with an original, signed W-9 form or its
equivalent prior to distribution.
(h) Any company into which the Depositary Agent may be
merged or with which it may be consolidated shall be the Successor to
the Depositary Agent without the execution or filing of any paper or
any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding, except that the Depositary
Agent shall provide written notice of such event to each of the parties
hereto.
7. Alteration of Duties.  The Duties may be altered, amended,
modified or revoked only by a writing signed by all of the parties
hereto.
8. Resignation and Removal of the Depositary Agent.  The
Depositary Agent may resign at any time upon giving at least thirty
(30) days' written notice to the parties; provided, however, that no
such resignation shall become effective until the appointment of a
successor Depositary Agent which shall be accomplished as follows: the
parties shall use their best efforts to mutually agree on a successor
Depositary Agent within thirty (30) days after receiving such notice.
If the parties fail to agree upon a successor Depositary Agent within
such time, the Depositary Agent shall have the right to appoint a
successor Depositary Agent authorized to do business in the State of
California.  The successor Depositary Agent shall execute and deliver
an instrument accepting such appointment and it shall, without further
acts, be vested with all the estates, properties, rights, powers, and
duties of the predecessor Depositary Agent as if originally named as
Depositary Agent. The Depositary Agent shall be discharged from any
further duties and liability under this Agreement.
9. Further Instruments.  If the Depositary Agent reasonably
requires other or further instruments in connection with performance of
the Duties, the necessary parties hereto shall join in furnishing such
instruments.
10. Disputes.  It is understood and agreed that should any
dispute arise with respect to the delivery, ownership, right of
possession, and/or disposition of the Escrow Shares, or should any
claim be made upon such shares by a third party, the Depositary Agent
upon receipt of written notice of such dispute or claim by the parties
hereto or by a third party, is authorized and directed to retain in its
possession without liability to anyone, all or any of said shares until

set forth in Section 10.6 of Article X. The Depositary Agent may, but
shall be under no duty whatsoever to, institute or defend any legal
proceedings which relate to the Escrow Shares.
11. Escrow Fees and Expenses.
All fees of the Depositary Agent for performance of its duties

substantial modification of its terms, or if any controversy arises, or
if the Depositary Agent is made a party to, or intervenes in, any
litigation pertaining to this escrow or its subject matter, the

SCHEDULE B
Vesting and Release Schedule
Initially, all Exchangeable Shares and Parent Common Shares (the
"Restricted Shares") shall be deposited with the Depositary Agent, who
shall establish a subaccount for each Holder (a "Holder's Account") and
two-thirds (2/3) of all vested options (the "Restricted Options") shall
be held by Parent, who shall establish a subaccount for each holder (a
"Holder's Option Account").
On the last day of each calendar month after the Closing Date
(the "Monthly Release Date") the Depositary Agent shall release and
forward to each holder an amount of Exchangeable Shares and Parent
Common Shares equal to 1/36th  (1/48th in the case of the Founders) of
the number of such shares (rounded down to the nearest whole share)
(the "Monthly Release Amount") initially deposited into the Holders
Account unless the Depositary Agent shall have received a Blockage
Notice.  If the Depositary Agent receives a Blockage Notice it shall,
until such Blockage Notice has been rescinded in writing, transfer and
deliver Restricted Shares representing all existing and future Monthly
Release Amounts to Parent.
On the last day of each calendar month after the Closing Date
(the "Monthly Release Date") Parent shall release and forward to each
holder an amount of Restricted Options equal to 1/36th  (1/48th in the
case of the Founders) of the number of such options (rounded down to
the nearest whole option) (the "Monthly Option Release Amount")
initially deposited into the Holders Option Account unless such holder
is terminated for Cause or has resigned Without Good Reason (as such
terms are defined below).  Any Restricted Options not delivered to such
holder shall be transferred to Parent.
"Blockage Notice" means a written notice by or on behalf of
Parent to the effect that the Holder has resigned from employment with
the Company Without Good Reason or has been terminated from employment
with Cause; provided that a Blockage Notice may only be issued to
Holder who was employed by the Company on or after September 30, 1999.
Termination for "Cause" shall mean a termination for any of the
following reasons:  (i) a conviction (excluding a conviction
successfully appealed) for fraud or embezzlement, (ii) willful and
serious dishonesty which has a material adverse effect upon the
business or affairs of the Company or Parent, (iii) repeated failure to
perform the lawful duties, functions and responsibilities of the
Holder's position when reasonably requested to do so, (iv) intentional
unauthorized use or disclosure of material confidential information,
trade secrets or other proprietary information which has a material
adverse effect upon the business or affairs of the Company or Parent,
(v) a material breach of the terms of any agreement between the Holder
and the Company or Parent that is not remedied within fifteen days of
receipt of written notice from the Company, or (vi) any other
intentional misconduct which has a material adverse effect upon the
business or affairs of the Company or Parent.
A resignation shall be "Without Good Reason" unless it is based
on:  (1) any reduction in a Holder's base salary, unless such reduction
is pursuant to a change in the Company's or Parent's compensation
policies generally; (2) a substantial diminution of the duties and
responsibilities of a Holder; (3) a relocation of a Holder's principal
place of employment by more than fifty (50) miles; (4) the failure by
the Company to continue in effect for a Holder's benefit any
perquisites or participation in any employee benefit plan to which
other employees of the Company are entitled, to the same extent to
which other similarly situated employees enjoy such benefits; or
(5) any other change which would constitute "constructive dismissal"
under applicable law.
In no event will any change to a Holder's title or reporting
responsibilities effected by reason of the corporate restructuring due
to Parent's acquisition of the Company constitute grounds for a good
cause resignation.
