ARTICLE 2

THE RIGHTS

2.1 Issue of Rights; Legend on Common Share Certificates

(a)   One Right has been issued in respect of each Common Share outstanding as at the Record Time and in respect of each Common Share issued after the Record Time.  One Right shall continue to be issued in respect of each Common Share issued after the date of this Agreement and prior to the earlier of the Separation Time and the Expiration Time.

(b)   Certificates for the Common Shares issued after the Record Time but prior to the earlier of the Separation Time and the Expiration Time shall evidence one Right for each Common Share represented thereby and, commencing as soon as reasonably practicable after the Record Time, shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

Until the earlier of Separation Time or the Expiration 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 Rights Plan Agreement, dated as of July 9, 1996, as amended and restated on March 14, 2002, May 13, 2005,  May 20, 2008 and May 4, 2011, as such from time to time may be amended, restated, varied or replaced, (the "Rights Agreement") between Tesco Corporation (the "Corporation") and Computershare Trust Company of Canada, as Rights Agent, the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive office of the Corporation and may be inspected by shareholders of the

Exh. 10.1 - 16

Corporation during normal business hours.  In 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, as soon as practicable after the receipt of a written request therefor.

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

2.2 Initial Exercise Price; Exercise of Rights; Detachment of Rights

(a)   Subject to adjustment as herein set forth, each Right will entitle the holder thereof, after the Separation Time and prior to the Expiration Time, to purchase, for the Exercise Price, as at the Business Day immediately preceding the day of exercise of the Right, one Common Share.  Notwithstanding any other provision of this Agreement, any Rights held by the Corporation or any of its Subsidiaries shall be void.

(b)   Until the Separation Time:

(i)   no Right may be exercised; and

(ii) each Right will be evidenced by the certificate for the associated Common Share registered in the name of the holder thereof (which certificate shall also be deemed to be a Rights Certificate) and will be transferable only together with, and will be transferred by a transfer of, such associated Common Share.

(c)  After the Separation Time and prior to the Expiration Time, the Rights (i) may be exercised; and (ii) the registration and transfer of the Rights shall be independent of Common Shares. Promptly following the Separation Time the Rights Agent will mail to each holder of record of Common Shares as of the Separation Time (other than an Acquiring Person and, in respect of any Rights Beneficially Owned by such Acquiring Person which are not held of record by such Acquiring Person, the holder of record of such Rights (a "Nominee")) and to each holder of Convertible Securities (other than an Acquiring Person or the Nominee of an Acquiring Person) at such holder's address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent for this purpose), (x) a certificate (a "Rights Certificate") in substantially the form of Exhibit A hereto with registration particulars appropriately completed, representing the number of Rights held by such holder at the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Corporation may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage, and (y) a disclosure statement prepared by the Corporation describing the Rights; provided that a Nominee shall be sent the materials provided for in (x) and (y) above in respect of all Common Shares or Convertible Securities held of record by it which are not Beneficially Owned by an Acquiring Person.  In order for the Corporation to determine whether any Person is holding Common Shares that are Beneficially Owned by another Person, the Corporation may require such Person to furnish such information and documentation as the Corporation deems necessary.

(d)  Rights may be exercised in whole or in part on any Business Day (or on any other day which, in the city at which an Election to Exercise (as hereinafter defined) is duly submitted to the Rights Agent in accordance with this Agreement, is not a Saturday, Sunday or a day that is treated as a holiday in such city) after the Separation Time and prior to the Expiration Time by submitting to the Rights Agent (at its office in Calgary, Alberta or at any other office of the Rights Agent in the cities designated from time to time for that purpose by the Corporation with the approval of the Rights Agent), the Rights Certificate evidencing such Rights together with an election to exercise such Rights (an "Election to Exercise") substantially in the form attached to the Rights Certificate duly completed and executed by the holder or his executors or administrators or other personal representatives or his or their legal attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Rights Agent, accompanied by payment by certified cheque, banker's draft, wire transfer or money order payable to the order of the Corporation, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being exercised.

Exh. 10.1 - 17

(e)  Upon receipt of a Rights Certificate, with an Election to Exercise accompanied by payment as set forth in Section 2.2(d) above, which does not indicate that the Rights represented thereby are null and void as provided by Section 3.l(b), the Rights Agent (unless otherwise instructed by the Corporation in the event that the Corporation is of the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:

(i)  requisition from the transfer agent of the Common Shares certificates for the number of Common Shares to be purchased (the Corporation hereby irrevocably authorizing its transfer agent to comply with all such requisitions);

(ii)   when appropriate, requisition from the Corporation the amount of cash to be paid in lieu of issuing fractional Common Shares;

(iii)   after receipt of the Common Share certificates, deliver the same to or to the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder;

(iv)   when appropriate, after receipt, deliver such cash to or to the order of the registered holder of the Rights Certificate; and

(v)   tender to the Corporation all payments received on the exercise of the Rights.

(f)  In case the holder of any Rights shall exercise less than all the Rights evidenced by such holder's Rights Certificate, a new Rights Certificate evidencing the Rights remaining unexercised will be issued by the Rights Agent to such holder or to such holder's duly authorized assigns.

(g)  The Corporation covenants and agrees that it will:

(i)  take all such action as may be necessary and within its power to ensure that all Common Shares delivered upon exercise of Rights shall, at the time of delivery of the certificates for such Common Shares (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered as fully paid and non-assessable;

(ii)  take all such action as may be necessary and within its power to comply with any applicable requirements of the Business Corporations Act, the Securities Act, the securities acts or comparable legislation of each of the other provinces of Canada, the 1933 Securities Act and the 1934 Exchange Act, and the rules and regulations thereunder and any other applicable law, rule or regulation, in connection with the issuance and delivery of the Rights Certificates and the issuance of any shares upon exercise of Rights;

Xxx. 00.0 - 00

(xxx)  use reasonable efforts to cause all Common Shares issued upon exercise of Rights to be listed on the principal exchanges or traded in the over-the-counter markets on which the Common Shares were traded immediately prior to the Stock Acquisition Date;

(iv)  cause to be reserved and kept available out of its authorized and unissued Common Shares a number of Common Shares that, as provided in this Agreement, will from time to time be sufficient to permit the exercise in full of all outstanding Rights;

(v)  pay when due and payable any and all Canadian and United States federal, provincial, and state transfer taxes (for greater certainty not including any income taxes of the holder or exercising holder or any liability of the Corporation to withhold tax) and charges which may be payable in respect of the original issuance or delivery of the Rights Certificates or certificates for Common Shares, provided that the Corporation shall not be required to pay any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for shares in a name other than that of the holder of the Rights being transferred or exercised; and

(vi)  after the Separation Time, except as permitted by Section 5.1, not take (or permit any Subsidiary 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.

2.3 Adjustments to Exercise Price; Number of Rights

The Exercise Price, the number and kind of shares 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.

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

(i)   declare or pay a dividend on the Common Shares payable in Common Shares (or other shares or securities exchangeable for or convertible into or giving a right to acquire Common Shares or other shares) other than pursuant to any optional stock dividend program;

(ii)   subdivide or change the then outstanding Common Shares into a greater number of Common Shares;

(iii)   combine or change the then outstanding Common Shares into a smaller number of Common Shares; or

(iv)   issue any Common Shares (or other shares or securities exchangeable for or convertible into or giving a right to acquire Common Shares or other shares) in respect of, in lieu of or in exchange for existing Common Shares in a reclassification, amalgamation, merger, statutory arrangement or consolidation;

Exh. 10.1 - 19

the Exercise Price and the number of Rights outstanding, or, if the payment or effective date therefor shall occur after the Separation Time, the securities purchasable upon exercise of Rights shall be adjusted in the manner set forth below.  If the Exercise Price and number of Rights outstanding are to be adjusted (x) the Exercise Price in effect after such adjustment shall be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of Common Shares (or other shares) (the "Expansion Factor") that a holder of one Common Share immediately prior to such dividend, subdivision, change, combination or issuance would hold thereafter as a result thereof and (y) each Right held prior to such adjustment shall become that number of Rights equal to the Expansion Factor, and the adjusted number of Rights will be deemed to be allocated 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, subdivision, change, combination or issuance, so that each such Common Share (or other share) will have exactly one Right associated with it.  If the securities purchasable upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right after such adjustment will be the number of securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision, change, combination or issuance would hold thereafter as a result thereof.  If after the Record Time and prior to the Expiration Time the Corporation shall issue any shares other than Common Shares in a transaction of a type described in Section 2.3(a)(i) or (iv), such shares shall be treated herein as nearly equivalent to Common Shares as may be practicable and appropriate under the circumstances and the Corporation and the Rights Agent agree to amend this Agreement in order to effect, and will not consolidate with, amalgamate with or into or enter into a statutory arrangement with, any other Person unless such Person agrees to be bound by the terms of an amendment effecting such treatment.  If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1 hereof, 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 hereof.  Adjustments pursuant to this Section 2.3(a) shall be made successively whenever an event referred to in this Section 2.3(a) occurs.

(b)  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. In the event the Corporation shall at any time after the Record Time and prior to the Expiration Time fix a record date for the making of a distribution to all holders of Common Shares of rights or warrants entitling them (for a period expiring within 60 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, if 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 (including the price required to be paid to purchase such convertible or

Exh. 10.1 - 20

exchangeable security or right per share)) less than the Market Price per Common Share on such record date, the Exercise Price shall be adjusted in the manner set forth below.  The Exercise Price in effect after such record date shall 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 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 so to be offered are initially convertible, exchangeable or exercisable).  In case such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights.  Such adjustment shall be made successively whenever such a record date is fixed.  For purposes of this paragraph (b), the granting of the right to purchase Common Shares (whether from treasury shares or otherwise) pursuant to any dividend or interest reinvestment plan and/or any Common 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 or similar plans (so long as such right to purchase is in no case evidenced by the delivery of rights or warrants) shall not be deemed to constitute an issue of rights or warrants by the Corporation; provided, however, that in the case of any dividend or interest reinvestment plan, the right to purchase Common Shares is at a price per share of not less than 90% of the current market price per share (determined as provided in such plans) of the Common Shares.

(c)  In the event the Corporation shall at any time after the Record Time and prior to the Expiration Time fix a record date for the making of a distribution to all holders of Common Shares of evidences of indebtedness or assets (other than an Annual Cash Dividend or a dividend paid in Common Shares) or rights or warrants (excluding those referred to in Section 2.3(b)), the Exercise Price shall be adjusted in the manner set forth below.  The Exercise Price in effect after such record date shall equal the Exercise Price in effect immediately prior to such record date less the fair market value (as determined in good faith by the Board of Directors) of the portion of the assets, evidences of indebtedness, rights or warrants so to be distributed applicable to each of the securities purchasable upon exercise of one Right (such determination to be described in a statement filed with the Rights Agent and the holders of the Rights).  Such adjustment shall be made successively whenever such a record date is fixed.

Xxx. 00.0 - 00

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

(i)  the payment or effective date for the applicable dividend, subdivision, change, combination or issuance, in the case of an adjustment made pursuant to paragraph (a) above; and

(ii)  the record date for the applicable dividend or distribution, in the case of an adjustment made pursuant to paragraph (b) or (c) above subject to readjustment to reverse the same if such distribution shall not be made.

(e) In the event the Corporation shall at any time after the Record Time and prior to the Expiration Time issue any shares (other than Common Shares), or rights or warrants to subscribe for or purchase any such shares, or securities convertible into or exchangeable for any such shares, in a transaction referred to in clause (a)(i) or (a)(iv) above, or if the Corporation shall take any other action (other than the issue of Common Shares) which might have a negative effect on the holders of Rights, if the Board of Directors acting in good faith determines that the adjustments contemplated by paragraphs (a), (b) and (c) above are not applicable or 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, if the adjustments contemplated by paragraphs (a), (b) and (c) above are applicable, notwithstanding such paragraphs, the adjustments so determined by the Corporation, rather than the adjustments contemplated by paragraphs (a), (b) and (c) above, shall be made.  The Corporation and the Rights Agent shall amend this Agreement in accordance with Section 5.4(b) and (c) as the case may be, to provide for such adjustments.

(f)  Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation shall:

(i)  promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment;

(ii)  promptly file with the Rights Agent and with each transfer agent for the Common Shares a copy of such certificate; and

(iii)  cause notice of the particulars of such adjustment or change to be given to the holders of the Rights by way of press release or by such other means as the Corporation may determine.

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 such adjustment.

Exh. 10.1 - 22

(g)  Irrespective of any adjustment or change in the securities purchasable upon exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the securities so purchasable which were expressed in the initial Rights Certificates issued hereunder.

(h)  Notwithstanding anything herein to the contrary, no adjustment in the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least one per cent in the Exercise Price; provided, however, that any adjustments which by reason of this Section 2.3(h) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.  All calculations under Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth of a share.  Notwithstanding the first sentence of this Section 2.3(h), any adjustment required by Section 2.3 shall be made no later than the earlier of:

(i)  three years from the date of the transaction which gives rise to such adjustment; or

(ii)  the Expiration Date.

(i)  Each Right originally issued by the Corporation subsequent to any adjustment made to the Exercise Price hereunder shall evidence the right to purchase, at the adjusted Exercise Price, the number of Common Shares purchasable from time to time hereunder upon exercise of a Right immediately prior to such issue, all subject to further adjustment as provided herein.

(j)  In any case in which this Section 2.3 shall require that an adjustment in the 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 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 Exercise Price in effect prior to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder's right to receive such additional shares (fractional or otherwise) or other securities upon the occurrence of the event requiring such adjustment.

(k)  Notwithstanding anything contained 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 their good faith judgment the Board of Directors determines to be advisable, in order that any:

Exh. 10.1 - 23

(i)  consolidation or subdivision of Common Shares;

(ii)  issuance (wholly or in part for cash) of Common Shares or securities that by their terms are convertible into or exchangeable for Common Shares;

(iii) stock dividends; or

(iv)  issuance of rights, options or warrants referred to in this Section 2.3,

hereafter made by the Corporation to holders of its Common Shares, shall not be taxable to such shareholders.

2.4 Date on Which Exercise is Effective

Each Person in whose name any certificate for Common Shares or other securities, if applicable, is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Shares represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered (together with a duly completed Election to Exercise) and payment of the Exercise Price for such Rights (and any applicable transfer taxes and other governmental charges payable by the exercising holder hereunder) was made; 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 record holder 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 any two officers or directors of the Corporation.  The signature of any of these officers or directors 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 or directors 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.  Promptly after the Corporation learns of 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 the Rights Agent shall countersign (manually or by facsimile signature in a manner satisfactory to the Corporation) and mail such Rights Certificates to the holders of the Rights pursuant to Section 2.2(c) hereof.  No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent as aforesaid.

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

2.6 Registration, Registration of Transfer and Exchange

(a)   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 of Rights as herein provided and the Rights Agent hereby accepts such appointment.  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 Section 2.6(d) below, the Corporation will execute, and the Rights Agent will countersign and deliver, 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 same benefits under this Agreement as the Rights surrendered upon such registration of transfer or exchange.

Xxx. 00.0 - 00

(x)   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 reasonable fees and expenses of the Rights Agent) in connection 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 in their sole discretion 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 reasonable fees and expenses of the Rights Agent) connected therewith.

Xxx. 00.0 - 00

(x)   Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence an original additional 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 of Rights

The Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name a 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 for all purposes whatsoever.  As used in this Agreement, unless the context otherwise requires, the term "holder" of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, the associated Common Shares).

2.9 Delivery and Cancellation of Certificates

All Rights Certificates surrendered upon exercise or for redemption, 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, subject to applicable law, 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 the same consents and agrees with the Corporation and the Rights Agent and with every other holder of Rights that:

(a)   he will 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 Certificates 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, the Rights Agent and any agent of the Corporation or 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 of Rights has waived his right to receive any fractional Rights or any fractional shares or other securities upon exercise of a Right (except as provided herein);

(f)   subject to the provisions of Section 5.4, without the approval of any holder of Rights and upon the sole authority of the Board of Directors acting in good faith this Agreement may be supplemented or amended from time to time to cure any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with the intent of this Agreement or is otherwise defective; 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 commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation.

ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN TRANSACTIONS

3.1 Flip-in Event

(a)  Subject to Sections 3.1(b), 5.1(b), 5.1(c) and 5.1(d) hereof, in the event that prior to the Expiration Time a Flip-in Event shall occur, the Corporation shall take such action as shall be necessary to ensure and provide, within 10 Business Days thereafter or such longer period as may be required to satisfy the requirements of the Securities Act, the 1933 Securities Act and the applicable securities acts or comparable legislation of each of the provinces of Canada and the states of the United States so that, except as provided below, each Right shall thereafter constitute 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 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 the foregoing or any other provisions of 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)   an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person); or

(ii)   a transferee, direct or indirect, from an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person) where such transferee becomes a transferee concurrently with or subsequent to the Acquiring Person becoming such, whether or not for consideration, that the Board of Directors acting in good faith has determined is part of a plan, arrangement or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person) that has the purpose or effect of avoiding clause (i) of this Section 3.1(b),

shall become void without any further action and any holder of such Rights (including transferees) shall thereafter have no right to exercise such Rights under any provision of this Agreement and shall not have any other rights whatsoever in respect of such Rights, whether under any provision of this Agreement or otherwise.

(c)  Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either clauses (i) or (ii) of Section 3.l(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:

Exh. 10.1 - 27

The Rights represented by this Rights Certificate were Beneficially Owned by a Person who was an Acquiring Person or who was an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Rights Agreement) or a Person who was acting jointly or in concert with any of them.  This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances specified in Section 3.l(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 be required to impose such legend only if instructed to do so by the Corporation or if a holder fails to certify upon transfer or exchange in the space provided on the Rights Certificate that such holder is not an Acquiring Person or an Affiliate or Associate thereof.

(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 Business Corporations Act, the Securities Act and the securities laws or comparable legislation of each of the provinces of Canada and of the United States and each of the states thereof in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.

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 ("Co-Rights Agents") as it may deem necessary or desirable, subject to the approval of the Rights Agent.  In the event the Corporation appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as the Corporation may determine with the approval of the Rights Agent and the Co-Rights Agent.  The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the execution and administration of this Agreement and the exercise and performance of its duties hereunder (including the reasonable fees and other disbursements of any expert retained by the Rights Agent with the approval of the Corporation, such approval not to be unreasonably withheld).  The Corporation also agrees to indemnify the Rights Agent for, and to hold it 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, suffered or omitted by the Rights Agent in connection with the acceptance, execution and administration of this Agreement and the exercise and performance of its duties hereunder, including legal costs and expenses of defending against any claim or liability, which right to indemnification will survive the termination of this Agreement and the resignation or removal of the Rights Agent.

Exh. 10.1 - 28

(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, opinion, 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.

(c)   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 certifying the then current officers of the Corporation.

4.2 Merger, Amalgamation 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, statutory arrangement 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 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.

Exh. 10.1 - 29

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 certificates for Common Shares and Convertible Securities 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 (such approval not to be unreasonably withheld) and at the expense of the Corporation, 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 act and 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 persons believed by the Rights Agent to be any two officers or directors 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 willful 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.

(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 Section 3.1 (b) hereof) or any adjustment required under the provisions of Section 2.3 hereof 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 Section 2.3 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.

Exh. 10.1 - 30

(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 persons believed by the Rights Agent to be any two officers or directors of 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 reliance upon instructions of any such persons; it is understood that instructions to the Rights Agent shall, except where circumstances make it impracticable or the Rights Agent otherwise agrees, be given in writing and, where not in writing, such instructions shall be confirmed in writing as soon as reasonably possible after the giving of such instructions.

(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.

(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, omission, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act, omission, 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 each 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 given to the Rights Agent and to each transfer agent of the Common Shares (by personal delivery, or registered or certified mail).  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

Exh. 10.1 - 31

incapacity by the resigning or incapacitated Rights Agent, then the resigning Rights Agent (at the Corporation's expense) or any holder of any Rights (which holder of Rights shall also submit his Rights Certificate for inspection by the Corporation) may apply to any court of competent jurisdiction for the appointment of a new Rights Agent.  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 authorized to carry on the business of a trust company in the Province of Alberta.  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 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 Termination

(a)   The Board of Directors may, with the prior consent of holders of Common Shares or of the holders of Rights given in accordance with Section 5.1(f) or (g), as the case may be, and in each case prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to the provisions of this Section 5.1, elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $.00001 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").

(b)   The Board of Directors may, with the prior consent of the holders of Common Shares given in accordance with Section 5.1(f), determine, at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to this Section 5.1, if such Flip-in Event would occur by reason of an acquisition of Common Shares otherwise than pursuant to a Takeover Bid made by means of a take-over bid circular sent to all holders of record of Common Shares and otherwise than in the circumstances set forth in Section 5.1(d), to waive the application of Section 3.1, on the same terms and conditions, to such Flip-in Event.  In the event that the Board of Directors proposes such a waiver, the Board of Directors shall extend the Separation Time to a date subsequent to and not more than ten Business Days following the meeting of shareholders called to approve such waiver.

Exh. 10.1 - 32

(c)   The Board of Directors may, at its option, prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived under this clause, determine, upon prior written notice to the Rights Agent, to waive the application of Section 3.1 to that Flip-in Event provided that the Flip-in Event would occur by reason of a Take-over Bid made by means of a take-over bid circular sent to all holders of record of Common Shares; further provided that if the Board of Directors waives the application of Section 3.1 to such a Flip-in Event, 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 made by means of a take-over bid circular to all holders of record of Common Shares which is made 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 Section 5.1(c).

(d)   The Board of Directors may, in respect of any Flip-in Event, waive the application of Section 3.1 to that Flip-in Event, provided that both of the following conditions are satisfied:

(i)   the Board of Directors has determined within ten Trading Days following the Stock Acquisition Date that the Acquiring Person became an Acquiring Person by inadvertence and without any intent or knowledge that it would become an Acquiring Person; and

(ii)   such Acquiring Person has within fourteen days after the determination in (i) above or such later date as determined by the Board of Directors, reduced its Beneficial Ownership of Common Shares such that at the time of waiver pursuant to this Section 5.1(d) it is no longer an Acquiring Person and has provided the Board of Directors with satisfactory evidence thereof;

and in the event of any such waiver, for the purposes of this Agreement, such Flip-in Event shall be deemed not to have occurred and the Separation Time shall be deemed not to have occurred as a result of such Person having inadvertently become an Acquiring Person.

(e)   The Board of Directors shall, without further formality, be deemed to have elected to redeem the Rights at the Redemption Price on the date that a Person who has made a Permitted Bid or a Take-over Bid in respect of which the Board of Directors has waived, or is deemed to have waived, pursuant to Section 5.1(c), the application of Section 3.1, takes up and pays for the Common Shares pursuant to the terms and conditions of the Permitted Bid or Take-over Bid, as the case may be.

Exh. 10.1 - 33

(f)   If a redemption of Rights pursuant to Section 5.1(a) or a waiver of a Flip-in Event pursuant to Section 5.1(b) is proposed at any time prior to the Separation Time, such redemption or waiver shall be submitted for approval to the holders of Common Shares. Such approval shall be deemed to have been given if the redemption or waiver is approved by the affirmative vote of a majority of the votes cast by Independent Shareholders represented in person or by proxy at a meeting of such holders duly held in accordance with applicable laws and the Corporation's by-laws.

(g)   If a redemption of Rights pursuant to Section 5.1(a) is proposed at any time after the Separation Time, such redemption shall be submitted for approval to the holders of Rights.  Such approval shall be deemed to have been given if the redemption is approved by holders of Rights by a majority of the votes cast by the holders of Rights represented in person or by proxy at and entitled to vote at a meeting of such holders.  For the purposes hereof, each outstanding Right (other than Rights which are Beneficially Owned by any Person referred to in clauses (i) to (v) inclusive of the definition of Independent Shareholders) 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 Business Corporations Act with respect to meetings of shareholders of the Corporation.

(h)   Where a Take-over Bid that is not a Permitted Bid is withdrawn or otherwise terminated after the Separation Time has occurred and 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 and reissue Rights under this Agreement to holders of record of Common Shares immediately following such time of redemption.  Notwithstanding such redemption, all of the provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and it shall be deemed not to have occurred and Rights shall remain attached to the outstanding Common Shares, subject to and in accordance with the provisions of this Agreement.

(i)   If the Board of Directors elects or is deemed to have elected to redeem the Rights, and, in circumstances where Section 5.l(a) is applicable, such redemption is approved by the holders of Common Shares or the holders of Rights in accordance with Section 5.l(f) or (g), as the case may be, the right to exercise the Rights will thereupon, without further action and without notice, terminate and the only right thereafter of the holders of Rights will be to receive the Redemption Price.

Exh. 10.1 - 34

(j)   Within 10 Business Days after the Board of Directors electing or having been deemed to have elected to redeem the Rights or, if Section 5.1(a) is applicable within 10 Business Days after the holders of Common Shares or the holders of Rights have approved a redemption of Rights in accordance with Section 5.1(f) or (g), as the case may be, the Corporation shall give notice of redemption to the holders of the then outstanding Rights by mailing such notice to each such holder at its last address as it appears upon the register of the Rights Agent or, prior to the Separation Time, on the register of the Transfer Agent for the Common Shares.  Any notice which is mailed in the manner herein provided will be deemed given, whether or not the holder receives the notice.  Each such notice of redemption will state the method by which the payment of the Redemption Price will be made.  The Corporation may not redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this Section 5.1 or in connection with the purchase of Common Shares prior to the Separation Time.

(k)   The Corporation shall give prompt 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 Section 4.l(a) of this Agreement.

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 its Board of Directors to reflect any adjustment or change in the number of 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)   The Corporation may make amendments to this Agreement to correct any clerical or typographical error or which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation, rules or regulations thereunder.  Notwithstanding anything in this Section 5.4 to the contrary, no such amendment shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such supplement or amendment.

Exh. 10.1 - 35

(b)   Subject to Section 5.4(a), the Corporation may, with the prior consent of the holders of Common Shares and the Independent Shareholders obtained as set forth below, at any time prior to the Separation Time, supplement, amend, vary, rescind or delete 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 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 the action requiring such approval is authorized by the affirmative vote of a majority of the votes cast by: (i) holders of Common Shares, and (ii) Independent Shareholders, present or represented at and entitled to be voted at a meeting of the holders of Common Shares duly called and held in compliance with applicable laws and the articles and by-laws of the Corporation.

(c)   Subject to subsection 5.4(a), the Corporation may, with the prior consent of the holders of Rights, at any time on or after the Separation Time, supplement, amend, vary, rescind or delete 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 amendment, variation or deletion shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent thereto.

(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 at and entitled to be voted at a meeting of the holders of Rights and representing a majority of the votes cast in respect thereof.  For the 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 Business Corporations Act with respect to meetings of shareholders of the Corporation.

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

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.

5.5 Fractional Rights and Fractional Shares

(a)   The Corporation shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights.  After the Separation Time there shall be paid to the registered holders of the Rights Certificates (provided the Rights represented by such Rights Certificates are not void pursuant to the provisions of Section 3.l(b)) with regard to which fractional Rights would otherwise be issuable, an amount in cash (rounded to the nearest cent) equal to the same fraction of the Market Price of a whole Right in lieu of such fractional Rights as of the date such fractional Rights would otherwise be issuable.

(b)   The Corporation shall not be required to issue fractional 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 (rounded to the nearest cent) equal to the same fraction of the Market Price of one Common Share at the date of such exercise.

5.6 Rights of Action

Subject to the terms of this Agreement, rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective holders of the Rights; and any holder of any Rights, without the consent of the Rights Agent or of the holder of any other Rights, may, on such holder's own behalf and for such holder's own benefit and the benefit of other holders of Rights, enforce, and may institute and maintain any suit, action or

Exh. 10.1 - 37

proceeding against the Corporation to enforce, or otherwise act in respect of, such holder's right to exercise such holder's Rights, or Rights to which he is entitled, in the manner provided in this Agreement and in such holder's Rights Certificate.  Without limiting the foregoing or any remedies available to the holders of Rights it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of, the obligations of any Person subject to this Agreement.

5.7 Holder of Rights Not Deemed a Shareholder

No holder, as such, of any Rights shall be entitled to vote, receive dividends or be deemed for any purpose the holder of Common Shares or any other securities which may at any time be issuable on the exercise of Rights, nor shall anything contained herein or in any Rights Certificate be construed to 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 any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting Shareholders (except as provided in Section 5.8 hereof), or to receive dividends or subscription rights or otherwise, until such Rights, or Rights to which such holder is entitled, shall have been exercised in accordance with the provisions hereof.
