                  Owner of 20% or more of the outstanding Voting Shares, but
                  shall not include:

(i)                 the Corporation or any Subsidiary of the Corporation;

(ii)                any Person who becomes the Beneficial Owner of 20% or more

                    provided, however, that if a Person becomes the Beneficial
                    Owner of 20% or more of the outstanding Voting Shares by
                    reason of a Voting Share Reduction, a Permitted Bid
                    Acquisition, an Exempt Acquisition or a Pro Rata
                    Acquisition, and thereafter becomes the Beneficial Owner of
                    a number of additional Voting Shares exceeding 1% of the
                    number of Voting Shares outstanding (other than pursuant to
                    a Voting Share Reduction, a Permitted Bid Acquisition, an
                    Exempt Acquisition or a Pro Rata Acquisition), then, as of
                    the date that such Person becomes the Beneficial Owner of
                    such additional Voting Shares, such Person shall become an

                    Owner of 20% or more of the outstanding Voting Shares as a
                    result of such Person becoming disqualified from relying on
                    Clause 1.1(d)(vii) solely because such Person or the
                    Beneficial Owner of such Voting Shares is making or has
                    announced an intention to make a Take-over Bid, either alone

                    public of securities; or

          (v)       a Person (a "Grandfathered Person") who is the Beneficial
                    Owner of 20% or more of the outstanding Voting Shares of the
                    Corporation determined as at the date hereof, provided,
                    however, that this exception shall not be, and shall cease
                    to


                                      -2-

                    be, applicable to a Grandfathered Person in the event that
                    such Grandfathered Person shall, after the date hereof,
                    become the Beneficial Owner of additional Voting Shares of

          A.        such security shall be deemed, in such case, to be
                    Beneficially Owned by such other Persons; and

          and provided further that, notwithstanding the foregoing, the Board of
          Directors shall have the right to and may determine, acting in good
          faith, that conditions exist which should disentitle the Manager from

                    any other Person;

          and provided further that, notwithstanding the foregoing, the Board of
          Directors shall have the right to and may determine, acting in good
          faith, that conditions exist which should disentitle the Trust Company
          from relying on this Clause 1.1(d)(viii) and, in such event, the Trust

          (x)       solely because any such Person, any of such Person's
                    Affiliates or Associates or any other Person referred to in
                    paragraph (iii) of this definition has an agreement,
                    arrangement or understanding, whether or not in writing (but
                    other than of the nature otherwise referred to in this
                    Subsection 1.1(d)), with respect to one or more shareholder
                    proposals or a matter or matters to come before a particular
                    meeting of shareholders, including the election of
                    directors.

          For purposes of this Agreement, in determining the percentage of the
          outstanding Voting Shares with respect to which a Person is or is

2.1      THE RIGHTS; LEGEND ON COMMON SHARE CERTIFICATES

          (a)       Certificates representing Common Shares that are issued and
                    outstanding at the later of the Record Time shall evidence
                    one Right for each Common Share evidenced thereby,
                    notwithstanding the absence of the legend referred to below,
                    until the earlier of (i) the Separation Time and (ii) the
                    Expiration Time. Certificates for Common Shares issued after
                    the later of (i) the Record Time and (ii) the date on which
                    all regulatory approvals for this Agreement have been
                    received but prior to the earlier of (i) the Separation Time
                    and (ii) the Expiration Time shall also evidence one Right
                    for each Common Share represented thereby.

          (b)       All such certificates for Common Shares shall have impressed
                    on, printed on, written on or otherwise affixed to them the
                    following legend:

          "Until the Separation Time (as defined in the Rights Agreement
          referred to below), this certificate also evidences and entitles the
          holder hereof to certain Rights as set forth in a Shareholder
          Protection Rights Agreement made as of January 13, 2000 (the "Rights
          Agreement"), between Salix Pharmaceuticals, Ltd. (the "Corporation")
          and Montreal Trust Company of Canada (the "Rights Agent"), the terms
          of which are incorporated herein by this reference and a copy of which
          is on file at the principal office of the Corporation. Under certain
          circumstances, as set forth in the Rights Agreement, such Rights may
          be amended or redeemed, may expire, may become void (if, in certain
          cases, they are "Beneficially Owned" by an "Acquiring Person", as such
          terms are defined in the Rights Agreement, or a transferee thereof),
          or may be evidenced by separate certificates and may no longer be
          evidenced by this certificate. The Corporation will mail, or arrange
          for the mailing of, a copy of the Rights Agreement to the holder of
          this certificate without charge promptly after the receipt of a
          written request therefor."

          Certificates representing Common Shares issued and outstanding at the
          Record Time shall also evidence one Right for each Common Share
          evidenced thereby, notwithstanding the absence of the foregoing
          legend, until the Close of Business on the earlier of the Separation
          Time and the Expiration Time.

2.2      INITIAL EXERCISE PRICE; EXERCISE OF RIGHTS; DETACHMENT OF RIGHTS

                    prior to the Expiration Time, to purchase one Common Share
                    for the Exercise Price, or the U.S. Dollar Equivalent of the
                    Exercise Price as at the Business Day immediately preceding
                    the Separation Time (which Exercise Price and number of
                    Common Shares are subject to adjustment as set forth below).
                    Notwithstanding any other provision of this Agreement, any

                  exercisable and no Right may be exercised and (ii) for
                  administrative purposes, each Right will be evidenced by the
                  certificate for the associated Common Share registered in the
                  name of the holder thereof (which certificate shall be deemed
                  to represent a Rights Certificate) and will be transferable
                  only together with, and will be transferred by a transfer of,
                  such associated Common Share.

                           or as may be required to comply with any law or with
                           any rule or regulation made pursuant thereto or with

                           to cover any transfer tax or charge which may be
                           payable in respect of any transfer involved in the

                           to time be sufficient to permit the exercise in full
                           of all outstanding Rights.

2.3      ADJUSTMENTS TO EXERCISE PRICE; NUMBER OF RIGHTS

         (a)      The Exercise Price, the number and kind of securities subject
                  to purchase upon exercise of each Right and the number of
                  Rights outstanding are subject to adjustment from time to time
                  as provided in this Section 2.3.

         (b)      In the event that the Corporation at any time after the Record
                  Time and prior to the Expiration Time:

                  (i)      declares or pays a dividend on the Common Shares
                           payable in Common Shares (or other securities
                           exchangeable for or convertible into or giving a
                           right to acquire Common Shares) other than pursuant
                           to any dividend reinvestment plan;

                  (ii)     subdivides or changes the then outstanding Common
                           Shares into a greater number of Common Shares;

                  (iii)    consolidates or changes the then outstanding Common
                           Shares into a smaller number of Common Shares; or

                  (iv)     issues any Common Shares (or other securities
                           exchangeable for or convertible into or giving a
                           right to acquire Common Shares) in respect of, in
                           lieu of, or in exchange for existing Common Shares,
                           except as otherwise provided in this Section 2.3,

                  then

A.                                       the Exercise Price shall be adjusted so
                                    that the Exercise Price in effect after such
                                    adjustment will be equal to the Exercise
                                    Price in effect immediately prior to such
                                    adjustment divided by the number of Common
                                    Shares (the "ADJUSTMENT FACTOR") that a
                                    holder of one Common Share immediately prior
                                    to such dividend, subdivision, change,
                                    consolidation or issuance would hold
                                    thereafter as a result thereof (assuming the
                                    exercise of all such exchange or conversion
                                    rights, if any); and

B.                                       in a case to which clause (ii) or (iii)
                                    applies or if clause (i) or (iv) applies to
                                    an issue of securities made after the
                                    Separation Time, the number of Rights
                                    outstanding shall be adjusted so that each
                                    Right held prior to such adjustment will
                                    become that number of Rights equal to the
                                    Adjustment Factor, and the adjusted number
                                    of Rights will be deemed to be distributed
                                    among the Common Shares with respect to
                                    which the original Rights were associated
                                    (if they remain outstanding) and the shares
                                    issued in respect of such dividend,

                                      -18-

                                    subdivision, change, consolidation or
                                    issuance, so that each such Common Share
                                    will have exactly one Right associated with
                                    it.

                  In the event the Corporation shall at any time after the
                  Record Time and prior to the Separation Time issue any Common
                  Shares otherwise than in a transaction referred to in the
                  preceding paragraph, each such Common Share so issued shall
                  automatically have one new Right associated with it, which
                  Right shall be evidenced by the certificate representing such
                  share.

         (c)       In the event that the Corporation at any time after the
                   Record Time and prior to the Expiration Time fixes a record
                   date for the making of a distribution to substantially all
                   holders of Common Shares of rights or warrants entitling them
                   (for a period expiring within 45 calendar days after such
                   record date) to subscribe for or purchase Common Shares (or
                   securities convertible into or exchangeable for or carrying a
                   right to purchase or subscribe for Common Shares) at a price
                   per Common Share (or, in the case of a security convertible
                   into or exchangeable for or carrying a right to purchase or
                   subscribe for Common Shares, having a conversion, exchange or
                   exercise price per share (including the price required to be
                   paid to purchase such convertible or exchangeable security or
                   right)) less than 90 percent of the Market Price per Common
                   Share on such record date, the Exercise Price shall be
                   adjusted. The Exercise Price in effect after such record date
                   will equal the Exercise Price in effect immediately prior to
                   such record date multiplied by a fraction, of which the
                   numerator shall be the number of Common Shares outstanding on
                   such record date plus the number of Common Shares which the
                   aggregate offering price of the total number of Common Shares
                   so to be offered (and/or the aggregate initial conversion,
                   exchange or exercise price of the convertible or exchangeable
                   securities or rights so to be offered, including the price
                   required to be paid to purchase such convertible or
                   exchangeable securities or rights) would purchase at such
                   Market Price per Common Share and of which the denominator
                   shall be the number of Common Shares outstanding on such
                   record date plus the number of additional Common Shares to be
                   offered for subscription or purchase (or into which the
                   convertible or exchangeable securities or rights to be so
                   offered are initially convertible, exchangeable or
                   exercisable). In case such subscription price may be paid in
                   a consideration part or all of which will be in a form other
                   than cash, the value of such consideration shall be as
                   determined by the Board of Directors. To the extent that such
                   rights or warrants are not exercised prior to the expiration
                   thereof, the Exercise Price shall be readjusted on the
                   expiration thereof to the Exercise Price which would then be
                   in effect based on the number of Common Shares (or securities
                   convertible into or exchangeable for Common Shares) actually
                   issued upon the exercise of such rights. For purposes of this
                   Agreement, the granting of the right to purchase Common
                   Shares (whether from treasury shares or otherwise) pursuant
                   to any dividend reinvestment plan and/or any share purchase
                   plan providing for the reinvestment of dividends or interest
                   payable on securities of the Corporation and/or the
                   investment of periodic optional payments and/or employee
                   benefit, stock option or similar plans (so long as such right
                   to purchase is in no case evidenced by the delivery of rights
                   or warrants by the Corporation) shall not be deemed to
                   constitute an issue of rights or warrants by the Corporation;
                   provided, however, that, in the case of any dividend
                   reinvestment plan or share purchase plan, the right to
                   purchase Common Shares is at a price per share of not less
                   than 90 percent of the current market price per share
                   (determined in accordance with such plans) of the Common
                   Shares.

         (d)       In the event that the Corporation at any time after the
                   Record Time and prior to the Expiration Time fixes a record
                   date for the making of a distribution to substantially all
                   holders of Common Shares of evidences of indebtedness or
                   assets (other than a Regular Periodic Cash Dividend or a
                   dividend paid in Common Shares but including any dividend
                   payable in securities other than a dividend or distribution
                   referred to in Subsection 2.3(b)(i) or 2.3(b)(iv)) or rights
                   or warrants entitling them to subscribe for or purchase
                   Common Shares (or securities convertible into or exchangeable
                   for or carrying a right to purchase or subscribe for Common
                   Shares) at a price per Common Share (or, in the case of a
                   security convertible into or exchangeable for or carrying a
                   right to purchase or subscribe for Common Shares, having a
                   conversion, exchange or exercise price per share (including
                   the price required to be paid to purchase such convertible or
                   exchangeable security or right)) less than 90 percent of the
                   Market Price per Common Share on such record date (excluding
                   rights or warrants referred to in Subsection 2.3(c)), the
                   Exercise Price in effect after such record date shall be
                   equal to the Exercise Price in effect immediately prior to
                   such record date less the fair market value (as determined by
                   the Board of Directors) of the portion of the assets,
                   evidences of indebtedness, rights or warrants so to be
                   distributed applicable to a Common Share.

         (e)       Each adjustment made pursuant to this Section 2.3 shall be
                   made as of:

(i)                              the record or effective date for the applicable
                           dividend, subdivision, change, consolidation or
                           issuance, in the case of an adjustment made pursuant
                           to Subsection 2.3(b); and

                  (ii)     the record date for the applicable dividend or
                           distribution, in the case of an adjustment made
                           pursuant to Subsection 2.3(c) or (d).

         (f)       In the event that the Corporation shall at any time after
                   the Record Time and prior to the Separation Time issue any
                   shares of capital stock (other than Common Shares), or rights
                   or warrants to subscribe for or purchase any such capital
                   stock, or securities convertible into or exchangeable for any
                   such capital stock, in a transaction referred to in Clauses
                   2.3(b)(i) or (iv), if the Board of Directors determines that
                   the adjustments contemplated by Subsections 2.3(b), (c) and
                   (d) in connection with such transaction will not
                   appropriately protect the interests of the holders of Rights,
                   the Corporation may determine what other adjustments to the
                   Exercise Price, number of Rights and/or securities
                   purchasable upon exercise of Rights would be appropriate and,
                   notwithstanding Subsections 2.3(b), (c) and (d), such
                   adjustments, rather than the adjustments contemplated by
                   Subsections 2.3(b), (c) and (d), shall be made. The
                   Corporation and the Rights Agent shall amend this Agreement
                   as appropriate to provide for such adjustments.

         (g)      Notwithstanding anything herein to the contrary, no adjustment
                  of the Exercise Price shall be required unless such adjustment
                  would require an increase or decrease of at least one per cent
                  in such Exercise Price; provided, however, that any
                  adjustments which by reason of this Subsection 2.3(g) are not
                  required to be made shall be carried forward and taken into
                  account in any subsequent adjustment. All adjustments made
                  pursuant to this Section 2.3 shall be made to the nearest cent
                  or to the nearest one ten-thousandth of a Common Share or a
                  Right, as the case may be.

         (h)      All Rights originally issued by the Corporation subsequent to
                  any adjustment made to an Exercise Price hereunder shall
                  evidence the right to purchase, at the adjusted Exercise

                                      -20-

                  Price, the number of Common Shares purchasable from time to
                  time hereunder upon exercise of the Rights, all subject to
                  further adjustment as provided herein.

         (i)      Unless the Corporation shall have exercised its election, as
                  provided in Subsection 2.3(j), upon each adjustment of an
                  Exercise Price as a result of the calculations made in
                  Subsections 2.3(c) and (d), each Right outstanding immediately
                  prior to the making of such adjustment shall thereafter
                  evidence the right to purchase, at the adjusted Exercise
                  Price, that number of Common Shares obtained by:

                  (i)      multiplying (A) the number of Common Shares covered
                           by a Right immediately prior to this adjustment, by
                           (B) the relevant Exercise Price in effect immediately
                           prior to such adjustment of the relevant Exercise
                           Price; and

                  (ii)     dividing the product so obtained by the relevant
                           Exercise Price in effect immediately after such
                           adjustment of the relevant Exercise Price.

         (j)       The Corporation may elect prior to or after the date of
                   any adjustment of an Exercise Price to adjust the number of
                   Rights, in lieu of any adjustment in the number of Common
                   Shares purchasable upon the exercise of a Right. Each of the
                   Rights outstanding after the adjustment in the number of
                   Rights shall be exercisable for the number of Common Shares
                   for which a Right was exercisable immediately prior to such
                   adjustment. Each Right held of record prior to such
                   adjustment of the number of Rights shall become the number of
                   Rights obtained by dividing the relevant Exercise Price in
                   effect immediately prior to adjustment of the relevant
                   Exercise Price by the relevant Exercise Price in effect
                   immediately after adjustment of the relevant Exercise Price.
                   The Corporation shall make a public announcement of its
                   election to adjust the number of Rights, indicating the
                   record date for the adjustment, and, if known at the time,
                   the amount of the adjustment to be made. This record date may
                   be the date on which the relevant Exercise Price is adjusted
                   or any day thereafter, but, if the Rights Certificates have
                   been issued, shall be at least 10 calendar days later than
                   the date of the public announcement. If Rights Certificates
                   have been issued, upon each adjustment of the number of
                   Rights pursuant to this Subsection 2.3(j), the Corporation
                   shall, as promptly as practicable, cause to be distributed to
                   holders of record of Rights on such record date, Rights
                   Certificates evidencing, subject to Section 5.5, the
                   additional Rights to which such holders shall be entitled as
                   a result of such adjustment, or, at the option of the
                   Corporation, shall cause to be distributed to such holders of
                   record in substitution and replacement for the Rights
                   Certificates held by such holders prior to the date of
                   adjustment, and upon surrender thereof, if required by the
                   Corporation, new Rights Certificates evidencing all the
                   Rights to which such holders shall be entitled after such
                   adjustment. Rights Certificates so to be distributed shall be
                   issued, executed and countersigned in the manner provided for
                   herein and may bear, at the option of the Corporation, the
                   relevant adjusted Exercise Price and shall be registered in
                   the names of holders of record of Rights Certificates on the
                   record date specified in the public announcement.

         (k)      Irrespective of any adjustment or change in the Exercise Price
                  or the number of securities issuable upon exercise of the
                  Rights, the Rights Certificates theretofore and thereafter
                  issued may continue to express the Exercise Price per Common
                  Share and the number of Common Shares so issuable which were
                  expressed in the initial Rights Certificates issued hereunder.

         (l)      In any case in which this Section 2.3 shall require that
<PAGE>

                   an adjustment in an Exercise Price be made effective as of a
                   record date for a specified event, the Corporation may elect
                   to defer until the occurrence of such event the issuance to
                   the holder of any Right exercised after such record date of
                   the number of Common Shares and other securities of the
                   Corporation, if any, issuable upon such exercise over and
                   above the number of Common Shares and other securities of the
                   Corporation, if any, issuable upon such exercise on the basis
                   of the relevant Exercise Price in effect prior to such
                   adjustment; provided, however, that the Corporation shall
                   deliver to such holder a due bill or other appropriate
                   instrument evidencing such holder's right to receive such
                   additional Common Shares (fractional or otherwise) or other
                   securities upon the occurrence of the event requiring such
                   adjustment.

         (m)       Notwithstanding anything in this Section 2.3 to the
                   contrary, the Corporation shall be entitled to make such
                   reductions in the Exercise Price, in addition to those
                   adjustments expressly required by this Section 2.3, as and to
                   the extent that in its good faith judgment the Board of
                   Directors shall determine to be advisable in order that any
                   (i) subdivision or consolidation of the Common Shares, (ii)
                   issuance wholly for cash of any Common Shares at less than
                   the applicable Market Price, (iii) issuance wholly for cash
                   of any Common Shares or securities that by their terms are
                   exchangeable for or convertible into or give a right to
                   acquire Common Shares, (iv) stock dividends or (v) issuance
                   of rights, options or warrants referred to in this Section
                   2.3, hereafter made by the Corporation to holders of its
                   Common Shares, subject to applicable taxation laws, shall not
                   be taxable to such shareholders.

         (n)      The Corporation covenants and agrees that, after the
                  Separation Time, it will not, except as permitted by Section
                  5.1 or 5.4, take (or permit any Subsidiary of the Corporation
                  to take) any action if at the time such action is taken it is
                  reasonably foreseeable that such action will diminish
                  substantially or otherwise eliminate the benefits intended to
                  be afforded by the Rights.

(o)                         If an event occurs which would require an adjustment
                   under both this Section 2.3 and Section 3.1, the adjustment
                   provided for in this Section 2.3 shall be in addition to and
                   shall be made prior to, any adjustment required pursuant to
                   Section 3.1.

         (p)      Whenever an adjustment to the Exercise Price or a change in
                  the securities purchasable upon exercise of the Rights is made
                  pursuant to this Section 2.3, the Corporation shall promptly:

                  (i)      file with the Rights Agent and with the transfer
                           agent for the Common Shares a certificate specifying
                           the particulars of such adjustment or change; and

                  (ii)     cause notice of the particulars of such adjustment
                           or change to be given to the holders of the Rights.

                  Failure to file such certificate or to cause such notice to be
                  given as aforesaid, or any defect therein, shall not affect
                  the validity of any such adjustment or change.

2.4      DATE ON WHICH EXERCISE IS EFFECTIVE

         Each Person in whose name any certificate for Common Shares is issued
upon the exercise of Rights shall for all purposes be deemed to have become the
holder of record of the Common Shares



                                      -22-
<PAGE>



represented thereby on, and such certificate shall be dated, the date upon which
the Rights Certificate evidencing such Rights was duly surrendered (together
with an appropriately completed and duly executed Election to Exercise) and
payment of the Exercise Price for such Rights (and any applicable transfer taxes
or charges payable by such Person hereunder) was made in accordance with
Subsection 2.2(d); provided, however, that if the date of such surrender and
payment is a date upon which the Common Share transfer books of the Corporation
are closed, such Person shall be deemed to have become the holder of record of
such shares on, and such certificate shall be dated, the next succeeding
Business Day on which the Common Share transfer books of the Corporation are
open.

2.5      EXECUTION, AUTHENTICATION, DELIVERY AND DATING OF RIGHTS CERTIFICATES

         (a)      The Rights Certificates shall be executed on behalf of the
                  Corporation by its Chief Executive Officer and its Chief
                  Financial Officer. The signature of these officers on the
                  Rights Certificates may be manual or facsimile. Rights
                  Certificates bearing the manual or facsimile signatures of
                  individuals who were at any time the proper officers of the
                  Corporation shall bind the Corporation, notwithstanding that
                  such individuals or any of them have ceased to hold such
                  offices prior to the countersignature and delivery of such
                  Rights Certificates.

         (b)      Promptly following the Separation Time, the Corporation will
                  notify the Rights Agent of such Separation Time and will
                  deliver Rights Certificates executed by the Corporation to the
                  Rights Agent for countersignature and a disclosure statement
                  describing the Rights, and the Rights Agent will manually
                  countersign such Rights Certificates and deliver such Rights
                  Certificates and statement to the holders of the Rights
                  pursuant to Subsection 2.2(c). No Rights Certificate shall be
                  valid for any purpose until countersigned by the Rights Agent
                  as aforesaid.

         (c)      Each Rights Certificate shall be dated the date of
                  countersignature thereof.

2.6      REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE

         (a)      After the Separation Time, the Corporation will cause to be
                  kept a register (the "RIGHTS REGISTER") in which, subject to
                  such reasonable regulations as it may prescribe, the
                  Corporation will provide for the registration and transfer of
                  Rights. The Rights Agent is hereby appointed "Rights
                  Registrar" for the purpose of maintaining the Rights Register
                  for the Corporation and registering Rights and transfers and
                  exchanges of Rights as herein provided. In the event that the
                  Rights Agent shall cease to be the Rights Registrar, the
                  Rights Agent will have the right to examine the Rights
                  Register at all reasonable times.

         (b)      After the Separation Time and prior to the Expiration Time,
                  upon surrender for registration of transfer or exchange of any
                  Rights Certificate, and subject to the provisions of
                  Subsection 2.6(d) and 3.1(b), the Corporation will execute,
                  and the Rights Agent will countersign, deliver and register,
                  in the name of the holder or the designated transferee or
                  transferees, as required pursuant to the holder's
                  instructions, one or more new Rights Certificates evidencing
                  the same aggregate number of Rights as did the Rights
                  Certificates so surrendered.

         (c)      All Rights issued upon any registration of transfer or
                  exchange of Rights Certificates shall be the valid obligations
                  of the Corporation, and such Rights shall be entitled to the


                                      -23-
<PAGE>


                  same benefits under this Agreement as the Rights surrendered
                  upon such registration of transfer or exchange.

         (d)      Every Rights Certificate surrendered for registration of
                  transfer or exchange shall be duly endorsed, or be accompanied
                  by a written instrument of transfer in form satisfactory to
                  the Corporation or the Rights Agent, as the case may be, duly
                  executed by the holder thereof or such holder's attorney duly
                  authorized in writing. As a condition to the issuance of any
                  new Rights Certificate under this Section 2.6, the Corporation
                  may require the payment of a sum sufficient to cover any tax
                  or other governmental charge that may be imposed in relation
                  thereto and any other expenses (including the fees and
                  expenses of the Rights Agent) connected therewith.

2.7      MUTILATED, DESTROYED, LOST AND STOLEN RIGHTS CERTIFICATES

         (a)      If any mutilated Rights Certificate is surrendered to the
                  Rights Agent prior to the Expiration Time, the Corporation
                  shall execute and the Rights Agent shall countersign and
                  deliver in exchange therefor a new Rights Certificate
                  evidencing the same number of Rights as did the Rights
                  Certificate so surrendered.

         (b)       If there shall be delivered to the Corporation and the
                   Rights Agent prior to the Expiration Time (i) evidence to
                   their satisfaction of the destruction, loss or theft of any
                   Rights Certificate and (ii) such security or indemnity as may
                   be required by them to save each of them and any of their
                   agents harmless, then, in the absence of notice to the
                   Corporation or the Rights Agent that such Rights Certificate
                   has been acquired by a bona fide purchaser, the Corporation
                   shall execute and upon its request the Rights Agent shall
                   countersign and deliver, in lieu of any such destroyed, lost
                   or stolen Rights Certificate, a new Rights Certificate
                   evidencing the same number of Rights as did the Rights
                   Certificate so destroyed, lost or stolen.

         (c)      As a condition to the issuance of any new Rights Certificate
                  under this Section 2.7, the Corporation may require the
                  payment of a sum sufficient to cover any tax or other
                  governmental charge that may be imposed in relation thereto
                  and any other expenses (including the fees and expenses of the
                  Rights Agent) connected therewith.

         (d)      Every new Rights Certificate issued pursuant to this Section
                  2.7 in lieu of any destroyed, lost or stolen Rights
                  Certificate shall evidence a contractual obligation of the
                  Corporation, whether or not the destroyed, lost or stolen
                  Rights Certificate shall be at any time enforceable by anyone,
                  and shall be entitled to all the benefits of this Agreement
                  equally and proportionately with any and all other Rights duly
                  issued hereunder.

2.8      PERSONS DEEMED OWNERS

         Prior to due presentment of a Rights Certificate (or, prior to the
Separation Time, the associated Common Share certificate) for registration of
transfer, the Corporation and any agent of the Corporation or, if so authorized
by the Corporation, the Rights Agent may deem and treat the person in whose name
such Rights Certificate (or, prior to the Separation Time, such Common Share
certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby for all purposes whatsoever. As used in this Agreement, unless
the context otherwise requires, the term "holder" of any Rights means the
registered holder of such Rights (or, prior to the Separation Time, the
associated Common Shares).

                                      -24-

<PAGE>

2.9      DELIVERY AND CANCELLATION OF CERTIFICATES

         All Rights Certificates surrendered upon exercise or for redemption, or
for registration of transfer or exchange shall, if surrendered to any person
other than the Rights Agent, be delivered to the Rights Agent and, in any case,
shall be promptly cancelled by the Rights Agent. The Corporation may at any time
deliver to the Rights Agent for cancellation any Rights Certificates previously
countersigned and delivered hereunder which the Corporation may have acquired in
any manner whatsoever, and all Rights Certificates so delivered shall be
promptly cancelled by the Rights Agent. No Rights Certificate shall be
countersigned in lieu of or in exchange for any Rights Certificates cancelled as
provided in this Section 2.9, except as expressly permitted by this Agreement.
The Rights Agent shall destroy all cancelled Rights Certificates and deliver a
certificate of destruction to the Corporation.

2.10     AGREEMENT OF RIGHTS HOLDERS

         Every holder of Rights, by accepting such Rights, consents and agrees
with the Corporation and the Rights Agent and with every other holder of Rights
that:

         (a)      such holder shall be bound by and subject to the provisions of
                  this Agreement, as amended from time to time in accordance
                  with the terms hereof, in respect of all Rights held;

         (b)      prior to the Separation Time, each Right will be transferable
                  only together with, and will be transferred by a transfer of,
                  the associated Common Share;

         (c)      after the  Separation  Time,  the Rights  will be
                  transferable  only on the Rights  Register  as provided
                  herein;

         (d)       prior to due presentment of a Rights Certificate (or,
                   prior to the Separation Time, the associated Common Share
                   certificate) for registration of transfer, the Corporation
                   and any agent of the Corporation or, if so authorized by the
                   Corporation, the Rights Agent may deem and treat the person
                   in whose name the Rights Certificate (or, prior to the
                   Separation Time, the associated Common Share certificate) is
                   registered as the absolute owner thereof and of the Rights
                   evidenced thereby (notwithstanding any notations of ownership
                   or writing on such Rights Certificate or the associated
                   Common Share certificate made by anyone other than the
                   Corporation or the Rights Agent) for all purposes whatsoever,
                   and neither the Corporation nor the Rights Agent shall be
                   affected by any notice to the contrary;

         (e)       such  holder is not  entitled  to receive  any  fractional
                   Rights or  fractional  Common  Shares upon the
                   exercise of Rights;

         (f)       without the approval of any holder of Rights and upon the
                   sole authority of the Board of Directors, this Agreement may
                   be supplemented or amended from time to time as provided
                   herein; and

         (g)       notwithstanding anything in this Agreement to the
                   contrary, neither the Corporation nor the Rights Agent shall
                   have any liability to any holder of a Right or any other
                   Person as a result of its inability to perform any of its
                   obligations under this Agreement by reason of any preliminary
                   or permanent injunction or other order, decree or ruling
                   issued by a court of competent jurisdiction or by a
                   governmental, regulatory or administrative agency or

                                      -25-

                  commission, or any statute, rule, regulation or executive
                  order promulgated or enacted by a governmental authority,
                  prohibiting or otherwise restraining performance of such
                  obligations.


                     ARTICLE 3 -- ADJUSTMENTS TO THE RIGHTS

3.1  FLIP-IN EVENT


(a)                         Subject to Section 3.1(b) and Subsections 5.1(d)
                  and 5.1(e), and except as provided below, if prior to the
                  Expiration Time a Flip-in Event shall occur, each Right shall
                  constitute, effective at the Close of Business on the 10th day
                  after the Stock Acquisition Date, the right to purchase from
                  the Corporation, upon exercise thereof in accordance with the
                  terms hereof, that number of Common Shares having an aggregate
                  Market Price on the date of consummation or occurrence of such
                  Flip-in Event equal to twice the Exercise Price for an amount
                  in cash equal to the Exercise Price (such Right to be
                  appropriately adjusted in a manner analogous to the applicable
                  adjustment provided for in Section 2.3 in the event that,
                  after such date of consummation or occurrence, or event, an
                  event of a type analogous to any of the events described in
                  Section 2.3 shall have occurred with respect to such Common
                  Shares).

(b)                         Notwithstanding anything to the contrary in this
                  Agreement, upon the occurrence of any Flip-in Event, any
                  Rights that are or were Beneficially Owned on or after the
                  earlier of the Separation Time or the Stock Acquisition Date
                  by:

(i)                                 (A)  an Acquiring Person;

                           (B)   any Affiliate or Associate of an Acquiring
                                 Person;

                           (C)   any Person acting jointly or in concert with an
                                 Acquiring Person or any of its Affiliates;

                           (D)   any other Person whose securities are deemed to
                                 be Beneficially Owned by an Acquiring Person

                           (each such Person being herein referred to as the
                           "INELIGIBLE SHAREHOLDER"); or

(ii)                             a transferee, direct or indirect, of an
                           Ineligible Shareholder who becomes a transferee in a
                           transfer, whether or not for consideration, that the
                           Board of Directors has determined is part of a plan,
                           arrangement or scheme of an Ineligible Shareholder
                           that has the purpose or effect of avoiding Clause
                           3.1(b)(i),

                  shall become null and void without any further action, and any
                  holder of such Rights (including a transferee of, or other
                  successor to, such Rights, whether directly or indirectly)
                  shall thereafter have no right to exercise such Rights under
                  any provision of this Agreement and shall not have thereafter
                  any right whatsoever with respect to such Rights, whether
                  under any provision of this Agreement or otherwise. The holder
                  of any Rights represented by a Rights Certificate which is
                  submitted to the Rights Agent upon exercise or for
                  registration of transfer or exchange which does not contain
                  the necessary certifications set forth in the Rights
                  Certificate establishing that such Rights are not void

                                      -26-
<PAGE>
                  under this Subsection 3.1(b), shall be deemed to be an
                  Acquiring Person or other Ineligible Shareholder for the
                  purposes of this Subsection 3.1(b) and such Rights shall
                  become null and void.

         (c)      Any Rights Certificates that represent Rights Beneficially
                  Owned by a Person described in either Clause (i) or (ii) of
                  Subsection 3.1(b) or transferred to any nominee of any such
                  Person, and any Rights Certificate issued upon transfer,
                  exchange, replacement or adjustment of any other Rights
                  Certificate referred to in this sentence, shall contain the
                  following legend:

                           "The Rights represented by this Rights Certificate
                           were issued to a Person who was an Acquiring Person
                           or an Affiliate or an Associate of an Acquiring
                           Person or other Ineligible Shareholder (as such terms
                           are defined in the Rights Agreement), including a
                           Person, or an Affiliate or Associate of a Person, who
                           was acting jointly or in concert with any of them or
                           any other Person whose securities are deemed to be
                           Beneficially Owned by such Acquiring Person. This
                           Rights Certificate and the Rights represented hereby
                           shall become void in the circumstances specified in
                           Subsection 3.1(b) of the Rights Agreement."

                  Provided, however, that the Rights Agent shall not be under
                  any responsibility to ascertain the existence of facts that
                  would require the imposition of such legend but shall impose
                  such legend only if instructed to do so by the Corporation in
                  writing of if a holder fails to certify upon transfer or
                  exchange in the space provided on the Rights Certificate that
                  such holder is not a Person described in such legend.

         (d)      From and after the Separation Time, the Corporation shall do
                  all such acts and things as shall be necessary and within its
                  power to ensure compliance with the provisions of this Section
                  3.1 including, without limitation, all such acts and things as
                  may be required to satisfy the requirements of the
                  Corporations Act and the Securities Act and any other
                  applicable laws in respect of the issue of Common Shares upon
                  the exercise of Rights in accordance with this Agreement.

3.2      EXCHANGE OPTION

         (a)      In the event that the Board of Directors determines that
                  conditions exist which would eliminate or otherwise materially
                  diminish in any respect the benefits intended to be afforded
                  to the holders of Rights pursuant to this Agreement, the Board
                  of Directors may, at its option and without seeking the
                  approval of the holders of Common Shares or Rights, at any
                  time after a Flip-in Event has occurred, authorize the
                  Corporation to issue or deliver in respect of each Right which
                  is not void pursuant to Subsection 3.1(b), either:

                  (i)      in return for the Exercise Price and the Right, cash,
                           debt or equity securities or other assets (or a
                           combination thereof) having a cash value equal to
                           twice the Exercise Price; or

                  (ii)     in return for the Right and without further charge,
                           subject to any amounts that may be required to be
                           paid under applicable law, cash, debt or equity
                           securities or other assets (or a combination thereof)
                           having a cash value equal to the Exercise Price,

                                      -27-
<PAGE>
                  in full and final settlement of all rights attaching to the
                  Rights, where in either case the value of such debt or equity
                  securities or other assets shall be determined by the Board of
                  Directors who may rely upon the advice of a nationally
                  recognized investment dealer or investment banker selected by
                  the Board of Directors. To the extent that the Board of
                  Directors determines that some action need be taken pursuant
                  to this Section 3.2, the Board of Directors may suspend the
                  exercisability of the Rights for a period of up to 90 days
                  following the date of the occurrence of the relevant Flip-in
                  Event in order to decide the appropriate form of distribution
                  to be made and to determine the value thereof. In the event of
                  any such suspension, the Corporation shall notify the Rights
                  Agent and issue as promptly as practicable a public
                  announcement stating that the exercisability of the Rights has
                  been temporarily suspended.

         (b)      If the Board of Directors authorizes the exchange of debt or
                  equity securities or other assets (or a combination thereof)
                  for Rights pursuant to Subsection 3.2(a), then, without any
                  further action or notice, the right to exercise the Rights
                  will terminate and the only right thereafter of a holder of
                  Rights shall be to receive such debt or equity securities or
                  other assets (or a combination thereof) in accordance with the
                  exchange formula authorized by the Board of Directors. Within
                  10 Business Days after the Board of Directors has authorized
                  the exchange of debt or equity securities or other assets (or
                  a combination thereof) for Rights pursuant to Subsection
                  3.2(a), the Corporation shall give notice of such exchange to
                  the holders of such Rights. Each such notice of exchange will
                  state the method by which the exchange of debt or equity
                  securities or other assets (or a combination thereof) for
                  Rights will be effected.

         (c)      The Corporation shall not be required to issue fractions of
                  securities or to distribute certificates evidencing fractional
                  securities. In lieu of issuing such fractional securities,
                  there shall be paid to the registered holders of Rights to
                  whom such fractional securities would otherwise be issuable,
                  an amount in cash equal to the same fraction of the Market
                  Price of a whole security.

3.3      FIDUCIARY DUTIES OF THE BOARD OF DIRECTORS OF THE CORPORATION

                  For clarification it is understood that nothing contained
in this Article 3 shall be considered to affect the obligations of the members
of the Board of Directors to exercise their fiduciary duties. Without limiting
the generality of the foregoing, nothing contained herein shall be construed to
suggest or imply that the Board of Directors shall not be entitled to recommend
that holders of the Voting Shares of the Corporation reject or accept any
Take-over Bid or take any other action (including, without limitation, the
commencement, prosecution, defence or settlement of any litigation and the
submission of additional or alternative Take-over Bids or other proposals to the
Special Meeting) with respect to any Take-over Bid that the Board of Directors
believes is necessary or appropriate in the exercise of the fiduciary duties of
its members.

                          ARTICLE 4 -- THE RIGHTS AGENT

4.1      GENERAL

         (a)      The Corporation hereby appoints the Rights Agent to act as
                  agent for the Corporation and the holders of Rights in
                  accordance with the terms and conditions hereof, and the
                  Rights Agent hereby accepts such appointment. The Corporation
                  may from time to time appoint such Co-Rights Agents as it may
                  deem necessary or desirable subject to the prior approval of
                  the Rights Agent. In the event the Corporation appoints one or
                  more Co-Rights Agents, the respective duties of the Rights
                  Agents and Co-Rights Agents shall be as the Corporation may
                  determine with the approval of the Rights Agent. The
                  Corporation agrees to pay to the Rights Agent reasonable
                  compensation for all services rendered by it hereunder (as per
                  the attached Fee Schedule) and, from time to time, on demand
                  of the Rights Agent, its reasonable expenses and counsel fees
                  and other disbursements incurred in the administration and
                  execution of this Agreement and the exercise and performance
                  of its duties hereunder (including the fees and disbursements
                  of any expert or advisor retained by the Rights Agent with the
                  approval of the Corporation). The Corporation also agrees to
                  indemnify the Rights Agent, its officers, directors and
                  employees for, and to hold them harmless against, any loss,
                  liability, or expense, incurred without negligence, bad faith
                  or wilful misconduct on the part of the Rights Agent, for
                  anything done or omitted by the Rights Agent in connection
                  with the acceptance and administration of this Agreement,
                  including the costs and expenses of defending against any
                  claim of liability, which right to indemnification will
                  survive the termination of this Agreement or the resignation
                  or removal of the Rights Agent. The Corporation shall inform
                  the Rights Agent in a reasonably timely manner of events which
                  may materially affect the administration of this Agreement by
                  the Rights Agent and at any time, upon request, shall provide
                  to the Rights Agent an incumbency certificate with respect to
                  the then current directors of the Corporation.

         (b)      The Rights Agent shall be protected and shall incur no
                  liability for or in respect of any action taken, suffered or
                  omitted by it in connection with its administration of this
                  Agreement in reliance upon any certificate for Common Shares,
                  Rights Certificate, certificate for other securities of the
                  Corporation, instrument of assignment or transfer, power of
                  attorney, endorsement, affidavit, letter, notice, direction,
                  consent, certificate, statement, or other paper or document
                  believed by it to be genuine and to be signed, executed and,
                  where necessary, verified or acknowledged, by the proper
                  Person or Persons.

4.2      MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT

         (a)      Any corporation into which the Rights Agent or any successor
                  Rights Agent may be merged or amalgamated or with which it may
                  be consolidated, or any corporation resulting from any merger,
                  amalgamation or consolidation to which the Rights Agent or any
                  successor Rights Agent is a party, or any corporation
                  succeeding to the shareholder or stockholder services business
                  of the Rights Agent or any successor Rights Agent, will be the
                  successor to the Rights Agent under this Agreement without the
                  execution or filing of any paper or any further act on the
                  part of any of the parties hereto, provided that such
                  corporation would be eligible for appointment as a successor
                  Rights Agent under the provisions of Section 4.4 hereof. In
                  case at the time such successor Rights Agent succeeds to the
                  agency created by this Agreement any of the Rights
                  Certificates have

                                      -29-
<PAGE>
                  been countersigned but not delivered, any such successor
                  Rights Agent may adopt the countersignature of the predecessor
                  Rights Agent and deliver such Rights Certificates so
                  countersigned; and in case at that time any of the Rights
                  Certificates have not been countersigned, any successor Rights
                  Agent may countersign such Rights Certificates either in the
                  name of the predecessor Rights Agent or in the name of the
                  successor Rights Agent; and in all such cases such Rights
                  Certificates will have the full force provided in the Rights
                  Certificates and in this Agreement.

         (b)      In case at any time the name of the Rights Agent is changed
                  and at such time any of the Rights Certificates shall have
                  been countersigned but not delivered, the Rights Agent may
                  adopt the countersignature under its prior name and deliver
                  Rights Certificates so countersigned; and in case at that time
                  any of the Rights Certificates shall not have been
                  countersigned, the Rights Agent may countersign such Rights
                  Certificates either in its prior name or in its changed name;
                  and in all such cases such Rights Certificates shall have the
                  full force provided in the Rights Certificates and in this
                  Agreement.

4.3      DUTIES OF RIGHTS AGENT

         The Rights Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, by all of which the
Corporation and the holders of Rights Certificates, by their acceptance thereof,
shall be bound:

         (a)      The Rights Agent may retain and consult with legal counsel
                  (who may be legal counsel for the Corporation), and the
                  opinion of such counsel will be full and complete
                  authorization and protection to the Rights Agent as to any
                  action taken or omitted by it in good faith and in accordance
                  with such opinion; the Rights Agent may also, with the
                  approval of the Corporation (where such approval may
                  reasonably be obtained and such approval not to be
                  unreasonably withheld), consult with such other experts as the
                  Rights Agent shall consider necessary or appropriate to
                  properly carry out the duties and obligations imposed under
                  this Agreement and the Rights Agent shall be entitled to rely
                  in good faith on the advice of any such expert;

         (b)      Whenever in the performance of its duties under this Agreement
                  the Rights Agent deems it necessary or desirable that any fact
                  or matter be proved or established by the Corporation prior to
                  taking or suffering any action hereunder, such fact or matter
                  (unless other evidence in respect thereof be herein
                  specifically prescribed) may be deemed to be conclusively
                  proved and established by a certificate signed by a person
                  reasonably believed by the Rights Agent to be a senior officer
                  of the Corporation and delivered to the Rights Agent; and such
                  certificate will be full authorization to the Rights Agent for
                  any action taken or suffered in good faith by it under the
                  provisions of this Agreement in reliance upon such
                  certificate;

         (c)      The Rights Agent will be liable hereunder only for its own
                  negligence, bad faith or wilful misconduct;

         (d)      The Rights Agent will not be liable for or by reason of any of
                  the statements of fact or recitals contained in this Agreement
                  or in the certificates for Common Shares or the Rights
                  Certificates (except its countersignature thereof) or be
                  required to verify the same, but all such statements and
                  recitals are and will be deemed to have been made by the
                  Corporation only;

                                      -30-
<PAGE>
         (e)      The Rights Agent will not be under any responsibility in
                  respect of the validity of this Agreement or the execution and
                  delivery hereof (except the due authorization, execution and
                  delivery hereof by the Rights Agent) or in respect of the
                  validity or execution of any Common Share certificate or
                  Rights Certificate (except its countersignature thereof); nor
                  will it be responsible for any breach by the Corporation of
                  any covenant or condition contained in this Agreement or in
                  any Rights Certificate; nor will it be responsible for any
                  change in the exercisability of the Rights (including the
                  Rights becoming void pursuant to Subsection 3.1(b)) or any
                  adjustment required under the provisions of Section 2.3 or
                  responsible for the manner, method or amount of any such
                  adjustment or the ascertaining of the existence of facts that
                  would require any such adjustment (except with respect to the
                  exercise of Rights after receipt of the certificate
                  contemplated by Subsection 2.3(p) hereof describing any such
                  adjustment); nor will it by any act hereunder be deemed to
                  make any representation or warranty as to the authorization of
                  any Common Shares to be issued pursuant to this Agreement or
                  any Rights or as to whether any Common Shares will, when
                  issued, be duly and validly authorized, executed, issued and
                  delivered and fully paid and non-assessable;

         (f)      The Corporation agrees that it will perform, execute,
                  acknowledge and deliver or cause to be performed, executed,
                  acknowledged and delivered all such further and other acts,
                  instruments and assurances as may reasonably be required by
                  the Rights Agent for the carrying out or performing by the
                  Rights Agent of the provisions of this Agreement;

         (g)      The Rights Agent is hereby authorized and directed to accept
                  instructions with respect to the performance of its duties
                  hereunder from any Person designated in writing by the
                  Corporation, and to apply to such persons for advice or
                  instructions in connection with its duties and it shall not be
                  liable for any action taken or suffered by it in good faith in
                  accordance with instructions of any such person;

         (h)      The Rights Agent and any shareholder or stockholder, director,
                  officer or employee of the Rights Agent may buy, sell or deal
                  in Common Shares, Rights or other securities of the
                  Corporation or become pecuniarily interested in any
                  transaction in which the Corporation may be interested, or
                  contract with or lend money to the Corporation or otherwise
                  act as fully and freely as though it were not Rights Agent
                  under this Agreement. Nothing herein shall preclude the Rights
                  Agent from acting in any other capacity for the Corporation or
                  for any other legal entity; and

         (i)      The Rights Agent may execute and exercise any of the rights or
                  powers hereby vested in it or perform any duty hereunder
                  either itself or by or through its attorneys or agents, and
                  the Rights Agent will not be answerable or accountable for any
                  act, default, neglect or misconduct of any such attorneys or
                  agents or for any loss to the Corporation resulting from any
                  such act, default, neglect or misconduct, provided reasonable
                  care was exercised in the selection and continued employment
                  thereof.

4.4      CHANGE OF RIGHTS AGENT

         The Rights Agent may resign and be discharged from its duties under
this Agreement upon 30 days' notice (or such lesser notice as is acceptable to
the Corporation) in writing mailed to the Corporation and to the transfer agent
of Common Shares by registered or certified mail, and to the holders of the
Rights in accordance with Section 5.8. The Corporation may remove the Rights
Agent upon 30 days' notice in writing, mailed to the Rights Agent and to the
transfer agent of the Common Shares by registered or certified mail, and to the
holders of the Rights in accordance with Section 5.8. If the Rights Agent should
resign or be removed or otherwise become incapable of acting, the Corporation
will appoint a successor to the Rights Agent. If the Corporation fails to make
such appointment within a period of 30 days after such removal or after it has
been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of any Rights (which holder shall,
with such notice, submit such holder's Rights Certificate for inspection by the
Corporation), then the resigning Rights Agent or the holder of any Rights may
apply to any court of competent jurisdiction for the appointment of a new Rights
Agent at the Corporation's expense. Any successor Rights Agent, whether
appointed by the Corporation or by such a court, shall be a corporation
incorporated under the laws of Canada or a province thereof. After appointment,
the successor Rights Agent will be vested with the same powers, rights, duties
and responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent upon receipt of all outstanding fees and expenses
owing by the Corporation to the predecessor Rights Agent under this Agreement,
any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Corporation will file
notice thereof in writing with the predecessor Rights Agent and each transfer
agent of the Common Shares, and mail a notice thereof in writing to the holders
of the Rights. Failure to give any notice provided for in this Section 4.4,
however, or any defect therein, shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the successor
Rights Agent, as the case may be.


         ARTICLE 5 -- MISCELLANEOUS

5.1      REDEMPTION AND WAIVER

         (a)      The Board of Directors may, at its option, at any time prior
                  to the occurrence of a Flip-in Event, elect to redeem all but
                  not less than all of the then outstanding Rights at a
                  redemption price of $0.0001 per Right appropriately adjusted
                  in a manner analogous to the applicable adjustment provided
                  for in Section 2.3 in the event that an event of the type
                  analogous to any of the events described in Section 2.3 shall
                  have occurred (such redemption price being herein referred to
                  as the "REDEMPTION PRICE"). The redemption of the Rights by
                  the Board of Directors may be made effective at such time, on
                  such basis and with such conditions as the Board of Directors
                  in its sole discretion may establish.

         (b)      If an Offeror successfully completes a Permitted Bid by having
                  taken up and paid for not less than 50 per cent of the Voting
                  Shares held by Independent Shareholders pursuant to Permitted
                  Bid Acquisitions, the Board of Directors shall, without
                  further formality, be deemed to have elected to redeem the
                  Rights at the Redemption Price on the Expiry Date of the
                  Permitted Bid.

         (c)                If the Board of Directors elects to or is deemed to
                  have elected to redeem the Rights, the right to exercise the
                  Rights will thereupon without further action and without

                                      -32-
<PAGE>
                  notice terminate and the only right thereafter of the holder
                  of a Right shall be to receive the Redemption Price. Within 10
                  days of the Board of Directors electing or being deemed to
                  have elected to redeem the Rights, the Corporation shall give
                  notice of such redemption to the holders of the then
                  outstanding Rights. Each such notice of redemption shall state
                  the method by which the payment of the Redemption Price shall
                  be made.

         (d)      The Board of Directors may until the occurrence of a Flip-in
                  Event determine, upon prior written notice delivered to the
                  Rights Agent, to waive the application of Section 3.1 to any
                  particular Flip-in Event (which for greater certainty shall
                  not include the circumstances described in Subsection 5.1(e));
                  provided that if the Board of Directors waives the application
                  of Section 3.1 to a particular Flip-in Event pursuant to this
                  Subsection 5.1(d), subject to as provided below the Board of
                  Directors shall be deemed to have waived the application of
                  Section 3.1 to any other Flip-in Event occurring by reason of
                  any Take-over Bid which is made by means of a take-over bid
                  circular (i) prior to the granting of such waiver, (ii)
                  thereafter and prior to the expiry of any Take-over Bid (as
                  the same may be extended from time to time) outstanding at the
                  time of the granting of such waiver or (iii) thereafter and
                  prior to the expiry of any Take-over Bid in respect of which a
                  waiver is, or is deemed to have been, granted under this
                  Subsection 5.1(d); provided further that if the first waiver
                  pursuant to this Subsection 5.1(d) is in respect of any bid
                  which would have been a Permitted Bid but for the absence of
                  one or more of the elements of a Permitted Bid set out in
                  subclauses 1.1(bb) (i), (ii), (iii) or (iv) (the "Waived
                  Conditions"), any such second or further waiver which is
                  deemed to occur by reason of Subsection 5.1(d) shall only be
                  deemed to occur if each such second or further Take-over Bid
                  would also be a Permitted Bid but for the Waived Conditions.

         (e)      The Board of Directors may prior to the Close of Business on
                  the tenth day following the Stock Acquisition Date determine,
                  upon prior written notice delivered to the Rights Agent, to
                  waive or to agree to waive the application of Section 3.1 to
                  the Flip-in Event giving rise to the Stock Acquisition Date,
                  provided that the Acquiring Person has (i) reduced its
                  Beneficial Ownership of Voting Shares or (ii) has entered into
                  a contractual arrangement with the Corporation, acceptable to
                  the Board of Directors, to do so within 30 days of the date on
                  which such contractual arrangement is entered into (the expiry
                  of which period is herein referred to as the "DISPOSITION
                  DATE"), such that at the time the waiver becomes effective
                  pursuant to this Subsection 5.1(e) such Person is no longer an
                  Acquiring Person. In the event of such a waiver becoming
                  effective, for the purposes of this Agreement, such Flip-in
                  Event shall be deemed not to have occurred. Without limiting
                  the generality of the foregoing, if the Person remains an
                  Acquiring Person at the close of business on the Disposition
                  Date, the Disposition Date shall be deemed to be the date of
                  occurrence of a further Stock Acquisition Date and Section 3.1
                  shall apply thereto.

         (f)      Where a Take-over Bid, or other events giving rise to a
                  Separation Time, is withdrawn or otherwise terminated after
                  the Separation Time has occurred and prior to the occurrence
                  of a Flip-in Event, or in any other circumstances prior to the
                  occurrence of a Flip-in Event, the Board of Directors may
                  elect to redeem all the outstanding Rights at the Redemption
                  Price. Without restricting the rights of the Board of
                  Directors to elect to redeem the Rights pursuant to section
                  5.1(a) rather than pursuant to section 5.1(f), upon the Rights
                  being redeemed pursuant to this section 5.1(f), all of the
                  provisions of this Agreement shall continue to apply as if the
                  Separation Time had not occurred and Rights Certificates
                  representing the number of Rights held by each holder of
                  record of Common

                                      -33-
<PAGE>
                  Shares as of the Separation Time had not been mailed to each
                  such holder and for all purposes of this Agreement the events
                  giving rise to the Separation Time shall be deemed not to have
                  occurred.

         (g)      The Corporation shall give prompt written notice to the Rights
                  Agent of any waiver of the application of Section 3.1 made by
                  the Board of Directors under this Section 5.1.

5.2      EXPIRATION

         No Person shall have any rights pursuant to this Agreement or in
respect of any Right after the Expiration Time, except the Rights Agent as
specified in Subsection 4.1(a) hereof.

5.3      ISSUANCE OF NEW RIGHTS CERTIFICATES

         Notwithstanding any of the provisions of this Agreement or of the
Rights to the contrary, the Corporation may, at its option, issue new Rights
Certificates evidencing Rights in such form as may be approved by the Board of
Directors to reflect any adjustment or change in the number or kind or class of
shares purchasable upon exercise of Rights made in accordance with the
provisions of this Agreement.

5.4      SUPPLEMENTS AND AMENDMENTS

         (a)      Without the approval of any holders of Voting Shares or
                  Rights, the Corporation may make amendments to this Agreement
                  to correct any clerical or typographical error, or which are
                  required to maintain the validity of the Agreement as a result
                  of any change in any applicable legislation or regulations
                  thereunder, or which are made to cure any ambiguity, defect or
                  inconsistency, or which are to make changes which do not
                  adversely affect the interests of holders of Rights (excluding
                  the interests of any Acquiring Person or other persons
                  identified in section 3.1(b) hereof), or which are to shorten
                  or lengthen any time period under the Rights Agreement;
                  provided, however, that no amendment to adjust the timer
                  period governing redemption shall be made at such time as the
                  Rights are not redeemable.. The Corporation may, prior to the
                  date of the shareholders' meeting referred to in Section
                  5.4(f), supplement or amend this Agreement without the
                  approval of any holders of Rights or Voting Shares in order to
                  make any changes which the Board of Directors acting in good
                  faith may deem necessary or desirable. Notwithstanding
                  anything in this Section 5.4 to the contrary, no supplement or
                  amendment shall be made to the provisions of Article 4 except
                  with the written concurrence of the Rights Agent to such
                  change, supplement or amendment.

         (b)      Subject to subsection 5.4(a), the Corporation may, with the
                  prior consent of the holders of Voting Shares obtained as set
                  forth below, at any time before the Separation Time, amend,
                  vary or rescind any of the provisions of this Agreement and
                  the Rights (whether or not such action would materially
                  adversely affect the interests of the holders of Rights
                  generally). Such consent shall be deemed to have been given if
                  the action requiring such approval is approved by the
                  affirmative vote of a majority of the votes cast by
                  Independent Shareholders represented in person or by proxy at
                  the Special Meeting.

         (c)      The Corporation may, with the prior consent of the holders of
                  Rights obtained as set forth below, at any time after the
                  Stock Acquisition Date amend, vary or rescind any of the
                  provisions of this Agreement and the Rights (whether or not
                  such action would materially adversely affect the interests of
                  the holders of Rights generally), provided that no such

                                      -34-
<PAGE>
                  amendment, variation or deletion shall be made to the
                  provisions of Article 4 except with the written concurrence of
                  the Rights Agent thereto. Such consent shall be deemed to have
                  been given if such amendment, variation or deletion is
                  authorized by the affirmative votes of the holders of Rights
                  present or represented at and entitled to vote at a meeting of
                  the holders and representing 50% plus one of the votes cast in
                  respect thereof.

         (d)      Any approval of the holders of Rights shall be deemed to have
                  been given if the action requiring such approval is authorized
                  by the affirmative votes of the holders of Rights present or
                  represented and entitled to vote at a meeting of the holders
                  of Rights and representing a majority of the votes cast in
                  respect thereof. For purposes hereof, each outstanding Right
                  (other than Rights which are void pursuant to the provisions
                  hereof) shall be entitled to one vote, and the procedures for
                  the calling, holding and conduct of the meeting shall be
                  those, as nearly as may be, which are provided in the
                  Corporation's by-laws and the Corporations Act with respect to
                  meetings of shareholders of the Corporation.

         (e)      Any amendments made by the Corporation to this Agreement
                  pursuant to Subsection 5.4(a) which are required to maintain
                  the validity of this Agreement as a result of any change in
                  any applicable legislation or regulation thereunder shall:

         (i)                if made before the Separation Time, be submitted to
                     the shareholders of the Corporation at the next meeting of
                     shareholders and the shareholders may, by the majority
                     referred to in subsection 5.4(b) confirm or reject such
                     amendment;

         (ii)               if made after the Separation Time, be submitted to
                     the holders of Rights at a meeting to be called for on a
                     date not later than immediately following the next meeting
                     of shareholders of the Corporation and the holders of
                     Rights may, by resolution passed by the majority referred
                     to in Subsection 5.4(d) confirm or reject such amendment.

                     Any such amendment shall be effective from the date of the
                     resolution of the Board of Directors adopting such
                     amendment, until it is confirmed or rejected or until it
                     ceases to be effective (as described in the next sentence)
                     and, where such amendment is confirmed, it continues in
                     effect in the form so confirmed. If such amendment is
                     rejected by the shareholders or the holders of Rights or is
                     not submitted to the shareholders or holders of Rights as
                     required, then such amendment shall cease to be effective
                     from and after the termination of the meeting at which it
                     was rejected or to which it should have been but was not
                     submitted or from and after the date of the meeting of
                     holders of Rights that should have been but was not held,
                     and no subsequent resolution of the Board of Directors to
                     amend this Agreement to substantially the same effect shall
                     be effective until confirmed by the shareholders or holders
                     of Rights as the case may be.

         (f)      The Board of Directors shall call and hold a Special Meeting
                  of holders of Voting Shares to consider and, if thought
                  appropriate, ratify the distribution and the continued

                  applicable laws and the articles and by-laws of the
                  Corporation. Unless a majority of the votes cast by the
                  Independent Shareholders on such resolution are voted in
                  favour of the continued existence of the Rights, then the
                  Board of Directors shall immediately upon the confirmation by
                  the Chairman of such shareholders' meeting of the result of
                  the vote on such resolution, without further formality, be
                  deemed to have elected to redeem the Rights at the Redemption

                  with notice in writing of any such amendment, recession or

                  variation.

                  Section 5.4(b) through (g) shall be subject to the receipt of
                  any requisite approval or consent from any governmental or

                  exchanges on which the Shares are listed (which supplement or
                  amendment shall be effective upon receipt of such approval

                  conditions which must be satisfied)).

5.5      FRACTIONAL RIGHTS AND FRACTIONAL SHARES

         (a)      The Corporation shall not be required to issue fractions of

                  fractional Rights. After the Separation Time, there shall be
                  paid to the registered holders of the Rights Certificates with
                  regard to which fractional Rights would otherwise be issuable,
                  an amount in cash equal to the same fraction of the Market
                  Price of a whole Right in lieu of such fractional Rights. The
                  Rights Agent shall have no obligation to make any payments in

                  Common Shares upon exercise of the Rights or to distribute
                  certificates which evidence fractional Common Shares. In lieu
                  of issuing fractional Common Shares, the Corporation shall pay
                  to the registered holder of Rights Certificates at the time
                  such Rights are exercised as herein provided, an amount in
                  cash equal to the same fraction of the Market Price of one
                  Common Share. The Rights Agent shall have no obligation to
                  make any payments in lieu of fractional Common Shares unless
                  the Corporation shall have provided the Rights Agent with the
                  necessary funds to pay in full all amounts payable in
                  accordance with Section 2.2 (e).

dividends or be deemed for any purpose the holder of Common Shares or any other

confer upon the holder of any Rights as such, any of the rights of a shareholder
of the Corporation or any right to vote for the election of directors or upon

                    SALIX PHARMACEUTICALS ADOPTS SHAREHOLDERS
                             RIGHTS PROTECTION PLAN

PALO ALTO, CA, JANUARY 17, 2000, -- Salix Pharmaceuticals, Ltd. (TSE: SLX) has
announced that its Board of Directors has approved the adoption of a
Shareholders' Rights Protection Plan, the purpose of which is to protect the
Company's shareholders from unfair or coercive take-over strategies, including
the acquisition of control of the Company through a take-over bid that does not
treat all shareholders equally or fairly or that does not provide fair value to
all shareholders in respect to their shares.

Under the Plan the rights will become exercisable if a person acquires, on or
after January 13, 2000, more than 20% of the common shares of the Company other
than pursuant to a Permitted Bid. Generally, to make a Permitted Bid, among
other things, the bidder must make a take-over bid for all outstanding common
shares of the Company, and the bid must be open for acceptance for not less than
60 days. The Rights Plan is not being adopted in response to any effort to
acquire control of the Company and the Board is not aware of any such effort.

The Rights Plan is subject to the approval of The Toronto Stock Exchange. The
Company will comply with all requirements imposed by the Exchange in respect of
the Rights Plan.

Salix Pharmaceuticals, Ltd. develops and markets prescription pharmaceutical
products for the treatment of gastrointestinal diseases. Salix's strategy is to
in-license proprietary therapeutic drugs with an existing database of positive,
late-stage clinical data in humans, complete the development and market these
products. Salix's lead product is Colazide, a treatment for ulcerative colitis.
The product was first approved by the United Kingdom Medicines Control Agency in
July 1997 as a treatment for acute ulcerative colitis and has since also been
approved

for use in the maintenance of remission of ulcerative colitis. Colazide
has also been approved in Argentina, Austria, Belgium, Czech Republic, Denmark,
Italy, Luxembourg, Norway, Sweden and Switzerland. Salix submitted a New Drug
Application (NDA) to the United States FDA for the use of balsalazide disodium
as a treatment for acute ulcerative colitis and received an approvable letter
from the FDA in June 1998.

Additionally, Salix is in Phase III clinical development of rifaximin, a
broad-spectrum gastrointestinal specific antibiotic, licensed from Alfa
Wassermann, S.p.A., an Italian company. Rifaximin has been marketed in Italy by
Alfa Wassermann for several years and is used for several gastrointestinal
conditions including hepatic encephalopathy, infectious diarrhea and prophylaxis
prior to bowel surgery.

The statements in this press release that are not purely statements of
historical fact are forward-looking statements, and actual results may differ
materially from those anticipated. With respect to Salix, important factors that
could cause results to differ include risks associated with anti-takeover
measures like the Shareholder Rights Plan. These and other factors are described
in more detail in Salix's reports on Form 10-K, Form 10-Q and Form 8-K filed
with the Securities and Exchange Commission. Readers are cautioned not to place
undue reliance on these forward-looking statements, which speak only as of the
date hereof. Salix assumes no obligation to update the information in this
release.
