(ii)	1.15 common shares of Golden Star Resources Ltd. plus Cdn.$0.50 in cash for each IAMGold common share (the “Cash and Share Option”);

         PLUS, in either case, Cdn.$0.20 in cash for each IAMGold common share, payable in the event that no break fee is paid or payable by IAMGold to Wheaton River Minerals Ltd. in connection with the proposed arrangement with Wheaton River Minerals Ltd. (as discussed below)

We hereby amend our offer to purchase all of the outstanding common shares of IAMGold Corporation. Under our increased offer, each holder of IAMGold shares will be entitled to receive, at such holder’s election, either (i) 1.25 common shares of Golden Star for each IAMGold common share; or (ii) 1.15 common shares of Golden Star plus Cdn.$0.50 in cash for each IAMGold common share; plus, in either case, Cdn.$0.20 in cash for each IAMGold share in the event that no break fee is paid or payable by IAMGold in connection with the proposed arrangement with Wheaton River Minerals Ltd. See Section 1, “Increase in Price Offered for IAMGold Shares”.

Our offer, as varied, will be open for acceptance until 9:00 p.m. (Toronto time) on July 16, 2004, unless extended or withdrawn.

Shareholders who wish to accept our offer must properly complete and execute the Letter of Transmittal (printed on orange paper) accompanying this Notice of Variation or a manually signed facsimile thereof and deposit it, together with the certificates representing their IAMGold shares, at one of the offices of CIBC Mellon Trust Company in accordance with the instructions in the Letter of Transmittal.

The closing price of the Golden Star shares on the TSX on May 27, 2004 was Cdn.$7.24.

Based on the trading price of the Golden Star shares and the IAMGold shares on the American Stock Exchange (the “AMEX”) on May 27, 2004, and without giving effect to the contingent payment referred to under the heading “Contingent Payment Entitlement”, our increased offer values each IAMGold share at U.S.$6.64, in the case of the All Share Option, and U.S.$6.48, in the case of the Cash and Share Option. Our increased offer represents a premium of approximately 22.3%, in the case of the All Share Option, and 19.3%, in the case of the Cash and Share Option, to the closing trading price of the IAMGold shares on the AMEX on May 27, 2004 of U.S.$5.43. Our increased offer represents a premium of approximately 23.6% in the case of the All Share Option, and 20.3%, in the case of the Cash and Share Option, based on the volume weighted average trading price of the Golden Star shares and the IAMGold shares for the 60 trading days ended May 27, 2004 of U.S. $5.65 and U.S. $5.71, respectively, on the AMEX.

NOTICE OF VARIATION

TO: THE HOLDERS OF SHARES OF IAMGOLD CORPORATION

      This Notice of Variation amends and supplements the Offer to Purchase and accompanying Circular dated June 9, 2004 (the “Offer and Circular”). Except as otherwise set forth in this Notice of Variation, the information, terms and conditions in the Offer and Circular continue to be applicable in all respects and this Notice of Variation should be read in conjunction with the Offer and the Circular provisions of which (as hereby amended) are incorporated herein by reference. References to the “Original Offer” mean our offer to acquire IAMGold shares set out in the Offer and Circular. References to the “offer” or the “increased offer” mean the Original Offer, as amended by this Notice of Variation.

1.   Increase in Price Offered for IAMGold Shares

      We have varied our Original Offer by increasing the consideration payable for the IAMGold shares to, at the option of each IAMGold shareholder:

	(i)	1.25 common shares of Golden Star Resources Ltd. for each common share of IAMGold (the “All Share Option”); or
	(ii)	1.15 common shares of Golden Star Resources Ltd. plus Cdn.$0.50 in cash for each common share of IAMGold (the “Cash and Share Option”);

PLUS, in either case, Cdn.$0.20 in cash for each IAMGold common share deposited, payable in the event that no break fee is paid or payable by IAMGold to Wheaton River Minerals Ltd. in connection with the proposed arrangement with Wheaton River. See “Contingent Payment Entitlement” below.

      Assuming that all of the conditions of the offer are satisfied or waived, all IAMGold shareholders whose IAMGold shares are taken up under the offer, including those shareholders who have already deposited their IAMGold shares to the Original Offer, will receive the increased price for their IAMGold shares. Shareholders who properly deposit their IAMGold shares to our offer but who have not properly elected to receive the All Share Option or the Cash and Share Option are deemed to have elected the All Share Option with respect to all of their IAMGold shares deposited under our offer.

      Based on the trading price of the Golden Star shares and the IAMGold shares on the TSX on May 27, 2004 (being the last trading day prior to the announcement of the proposed combination between IAMGold and Golden Star), and without giving effect to the contingent payment discussed under the heading “Contingent Payment Entitlement” below, our increased offer values each IAMGold share at Cdn.$9.05, in the case of the All Share Option, and Cdn.$8.83, in the case of the Cash and Share Option. Our increased offer represents a premium of approximately 22.6%, in the case of the All Share Option, and 19.6%, in the case of the Cash and Share Option, to the closing trading price of the IAMGold shares on the TSX on May 27, 2004 of Cdn.$7.38. In the event that Golden Star pays the contingent payment to shareholders, the increased offer values each IAMGold share at Cdn.$9.25, in the case of the All Share Option, and Cdn.$9.03, in the case of the Cash and Share Option, representing a premium of 25.3% in the case of the All Share Option, and 22.4%, in the case of the Cash and Share Option, to the closing trading price of the IAMGold shares on the TSX on May 27, 2004.

      Based on the trading price of the Golden Star shares and the IAMGold shares on the AMEX on May 27, 2004, and without giving effect to the contingent payment discussed under the heading “Contingent Payment Entitlement” below, our increased offer values each IAMGold share at U.S.$6.64, in the case of the All Share Option, and U.S.$6.48, in the case of the Cash and Share Option, representing a premium of approximately 22.3%, in the case of the All Share Option, and 19.3%, in the case of the Cash and Share Option, to the closing trading price of the IAMGold shares on the AMEX on May 27, 2004 of U.S.$5.43. In the event that Golden Star makes the contingent payment to shareholders, the increased offer values each IAMGold share at U.S.$6.79, in the case of the All Share Option, and U.S.$6.63, in the case of the Cash and Share Option, representing a premium of 25.0%, in the case of the All Share Option, and 22.1%, in the case of the Cash and Share Option, to the closing trading price of the IAMGold shares on the AMEX on May 27, 2004.

Table of Contents

      We believe that the offer to IAMGold shareholders is superior to the proposed combination of IAMGold and Wheaton River announced in March, 2004.

      The increased offer will be open for acceptance until 9.00 p.m. (Toronto time) on July 16, 2004 unless withdrawn or extended.

          Contingent Payment Entitlement

      Under the arrangement agreement between IAMGold and Wheaton River, a break-fee is payable by IAMGold to Wheaton River, or by Wheaton River to IAMGold, if the arrangement agreement is terminated in certain circumstances as set out in Section 3 of the Circular, “Background to the Offer — Pre-Offer Agreement with Coeur d’Alene”. In the event that we determine that no break-fee is paid or payable by IAMGold to Wheaton River under the arrangement agreement (as may be amended from time to time), and regardless of whether IAMGold is or is not entitled to a break-fee from Wheaton River or whether IAMGold is or is not entitled to a payment from Wheaton River or Coeur d’Alene under the terms of the agreement we entered into with Coeur d’Alene to net potential break-fees payable by Wheaton River and IAMGold, we will pay to each IAMGold shareholder an additional Cdn.$0.20 in cash for each IAMGold share deposited under the offer which we take up and pay for. The contingent payment, if payable, will be paid to shareholders depositing IAMGold shares to our offer as soon as is reasonably practicable once we have definitively determined that no break-fee is paid or payable by IAMGold under the arrangement agreement (as may be amended from time to time). There can be no assurance that IAMGold shareholders will receive the contingent payment or of the timing of such payment.

      To permit a partial tax-deferred rollover to IAMGold shareholders who are resident in Canada, the offer is made to all shareholders on the basis that the Cash-Out Percentage of an IAMGold share held by a particular shareholder who elects under the Cash and Share Option will be exchanged for cash, the CPE Percentage of an IAMGold share held by each shareholder will be exchanged for the contingent payment entitlement and the Remaining Percentage of an IAMGold share held by each shareholder will be exchanged solely for Golden Star shares. These percentages are defined in Section 10 of this Notice of Variation, “Certain Canadian Federal Income Tax Considerations”.

2.   Conditions to the Offer

      The offer remains subject to all of the conditions contained in Section 2 of the Offer to Purchase dated June 9, 2004, “Conditions to the Offer”.

3.   Change in Information in the Offer and Circular

	Summary of Golden Star and IAMGold Historical and Pro Forma Financial Data

      As a result of the increase in the consideration offered under our offer, the Summary of Golden Star and IAMGold Historical and Pro Forma Financial Data in the Summary of the Offer and Circular has been changed to the following:

Summary Golden Star and IAMGold Historical and Pro Forma Financial Data

      The following tables present summary historical consolidated financial information for Golden Star and IAMGold as of and for the years ended December 31, 1999, 2000, 2001, 2002 and 2003 and consolidated financial information for Golden Star and IAMGold as of and for the three-month period ended March 31, 2004, under both U.S. GAAP and Canadian GAAP. The tables also present pro forma consolidated financial information for Golden Star as of and for the year ended December 31, 2003 and the three-month period ended March 31, 2004 after giving effect to the acquisition by Golden Star of all of the IAMGold shares pursuant to the offer, under Canadian GAAP only.

          Reasons for Proposed Combination

      The Circular indicates that, on a pro forma basis, the combined company resulting from the combination of Golden Star and IAMGold would have approximately U.S.$185 million in cash, cash equivalents and bullion (assuming a break fee of U.S.$23 million is paid to Wheaton River). Based on the addition of the cash portion of the purchase price for the IAMGold shares, the cash, cash equivalents and bullion of the combined

          Source of Offered Consideration

      Assuming that all of the depositing shareholders elect the All Share Option and all of the IAMGold shares that are issued and outstanding as of June 4, 2004 (and all IAMGold shares issuable upon exercise of options to acquire IAMGold shares that are in-the-money at June 28, 2004) are tendered to the offer and that we take up and pay for such IAMGold shares under the offer, we will issue approximately 186.6 million Golden Star shares. If all of the IAMGold shareholders elect the All Share Option and all of the shares issuable upon the exercise of all IAMGold options outstanding on June 4, 2004 were tendered to the offer and taken up and paid under the offer, the number of Golden Star shares issued would increase to 189.4 million. If all of the depositing shareholders elect the Cash and Share Option, and all of the IAMGold shares that are issued and outstanding as of June 4, 2004 (and all IAMGold shares issuable upon exercise of options to acquire IAMGold shares that are in-the-money at June 28, 2004) are tendered to the offer and that we take up and pay for such IAMGold shares under the offer, we will issue approximately 171.7 million Golden Star shares and pay approximately Cdn.$74.7 million in cash to depositing shareholders. If all of the IAMGold shareholders elect the Cash and Share Option and all of the shares issuable upon the exercise of all IAMGold options outstanding on June 4, 2004 were tendered to the offer and taken up and paid for under the offer, the number of Golden Star shares issued would increase to 174.2 million and the cash paid would increase to Cdn.$75.8 million. If the contingent payment referred to in Section 1 of this Notice of Variation, “Increase in Price Offered for IAMGold Shares — Contingent Payment Entitlement” is payable, we will pay to IAMGold shareholders an additional Cdn.$29.9 million in cash, if all of the IAMGold shares issued and outstanding as at June 4, 2004 (and all IAMGold shares issuable upon exercise of IAMGold options that are in the money at June 28) are deposited under the offer and taken up and paid for. If all of the IAMGold shares issued and outstanding as at June 4, 2004, including all shares issuable upon exercise of options outstanding on that date, are deposited under the offer and taken up and paid for, the contingent payment payable by us would be approximately Cdn.$30.3 million.

      We have sufficient cash on hand and liquid investments (which may be readily converted into cash) to fund the cash portion of the offer, including the contingent payment. We may choose to finance all or any part of the cash portion of the offer, including the contingent payment, through other means.

      Certain data of a scientific or technical nature regarding our mineral reserves and mineral resources included in this Notice of Variation were previously verified by our full-time employees, Mr. Dave Alexander, Project Planning Manager in Ghana, and Mr. Mitchell Wasel, Exploration Manager in Ghana. Each of Messrs. Alexander and Wasel is a “qualified person”, as defined in National Instrument 43-101 — Standards of Disclosure for Mineral Projects (“National Instrument 43-101”) and, in addition to their employment with us, each beneficially owns common shares, including common shares issuable upon exercise of options, consisting of less than 1% of our outstanding common shares.

      The above statements of mineral resources at Wassa and at Bogoso/ Prestea were prepared by Mr. Wasel. The above statements of mineral resources for the Yaou, Dorlin and Paul Isnard properties were prepared by Mr. Colin Jones, Partner and Manager (Audits) of RSG Global Pty Ltd., given on his authority as an expert in mining engineering and geology and as a “qualified person” within the meaning of National Instrument 43-101. To the best of our knowledge, neither Mr. Jones nor any of the officers, directors and other employees of RSG Global Pty Ltd. hold any of our common shares. Please refer to the disclosure under the heading “Interests of Experts” in the Offer and Circular for a statement of the qualified persons who prepared the technical reports for each of the foregoing properties and the relationship of such qualified persons to Golden Star.

          Revised Pro Forma Financial Statements

      Attached as Annex A to this Notice of Variation are revised pro forma financial statements of Golden Star replacing pages B-1 to B-15 of Annex B to the Offer and Circular. These statements have been amended to reflect the increase in the consideration offered for IAMGold shares under our offer, as well as certain other consequential changes.

4.   Recent Developments

      We filed the Offer and Circular and the related prospectus with Canadian and U.S. securities regulatory authorities on June 10, 2004 and commenced mailing the offer documents to IAMGold shareholders on June 10, 2004. During the period following June 7, 2004, our management and financial advisors contacted numerous IAMGold shareholders regarding the offer.

      On June 10, 2004, we sent a letter to IAMGold requesting, among other things, that IAMGold provide us with certain non-public information of IAMGold so that we would be able to satisfy the due diligence conditions of the offer. We also requested that IAMGold appoint an independent chair to conduct the adjourned meeting of shareholders of IAMGold, then scheduled for June 29, 2004, with access to his or her own legal counsel to provide additional comfort that the adjourned IAMGold meeting would run smoothly and that all registered and non-registered IAMGold shareholders would be enfranchised. We suggested that the independent chair could not only conduct the adjourned IAMGold meeting, but also establish detailed rules for the delivery and revocation of proxies and rule on the acceptability of certain proxies if appropriate. Finally, we requested that the proxy deadline for the adjourned IAMGold meeting should be 5:00 p.m. (Toronto time) on the day immediately prior to the adjourned IAMGold meeting in order to allow IAMGold shareholders as much time as possible to consider the relative merits of our offer and the proposed IAMGold/ Wheaton River transaction.

      On June 11, 2004, IAMGold announced that it had appointed a special committee of its board of directors to consider our offer in comparison with the proposed IAMGold/ Wheaton River transaction, and to make recommendations to IAMGold’s board of directors. IAMGold also announced that, after receiving a report and recommendations of the IAMGold special committee, IAMGold’s board of directors planned to send to its shareholders a supplement to the joint management information circular dated April 30, 2004 regarding the proposed IAMGold/ Wheaton River transaction. IAMGold asked its shareholders to take no action with respect to our offer or the Wheaton River transaction until its board of directors communicated its assessments and recommendations regarding the proposed transactions.

      On June 11, 2004, our Canadian counsel, Fasken Martineau DuMoulin LLP, sent a letter to the IAMGold special committee requesting that the IAMGold special committee change the record date for voting for the adjourned IAMGold meeting from April 28, 2004 to on or about June 8, 2004 to ensure that

      Also on June 11, Wheaton River announced that it would hold a further vote of its shareholders to consider the IAMGold/ Wheaton River transaction on July 6, 2004.

      On June 14, 2004, Borden Ladner Gervais LLP, counsel to certain IAMGold shareholders, sent a letter to the IAMGold special committee requesting that the IAMGold special committee consider: (i) a change in the record date for voting for the adjourned IAMGold meeting; and (ii) making the proxy deadline a time immediately prior to the commencement of the adjourned IAMGold meeting.

      On June 14, 2004, we mailed a proxy circular to shareholders recommending shareholders vote against the IAMGold/ Wheaton River transaction at the adjourned IAMGold meeting.

      On June 15, 2004, certain IAMGold shareholders brought a motion to be heard by the Court on June 24, 2004 seeking an order: (i) changing the record date for voting at the adjourned IAMGold meeting; and (ii) determining the proxy deadline for the adjourned IAMGold meeting. We supported the position taken by the shareholders.

      IAMGold announced on June 16, 2004 that the special committee had appointed RBC Dominion Securities Inc. and Ogilvy Renault as its financial and legal advisors respectively. At the request of RBC Dominion Securities Inc., Messrs. Bradford, Marter and Higson-Smith and Golden Star’s financial advisors met on June 18, 2004 with Mr. Robert Quartermain, a director and member of IAMGold’s special committee, and IAMGold’s financial advisors. Messrs. Bradford and Marter made a presentation regarding Golden Star and the proposed business combination and Golden Star representatives responded to questions regarding Golden Star, its operations and its offer.

      On June 21, 2004, Coeur d’Alene Mines Corporation announced an increase in its proposed offer to Wheaton River and that it had begun mailing an information circular to Wheaton River shareholders recommending they vote against the IAMGold/ Wheaton River transaction at the special meeting of Wheaton River’s shareholders scheduled for July 6, 2004.

      In a letter dated June 22, 2004, Don Charter, the Chair of the IAMGold special committee, advised Mr. Bradford, our President and Chief Executive Officer, of the following (i) IAMGold would not provide us with access to non-public information concerning IAMGold; and (ii) the IAMGold special committee would not recommend the appointment of an independent chair for the adjourned IAMGold meeting or a change to the record date for the adjourned IAMGold meeting. Mr. Charter also indicated that the IAMGold special committee was recommending that the proxy deadline be 5:00 p.m. on the business day immediately prior to the adjourned IAMGold meeting.

      On June 23, 2004, IAMGold announced that its board of directors unanimously recommended that IAMGold shareholders reject our Original Offer and vote in favour of the Wheaton River transaction. IAMGold also stated that the IAMGold meeting would be postponed to July 6, 2004, and proposed that the proxy deadline be extended to 5:00 p.m. (Toronto time) on July 5, 2004.

      On June 23, 2004, Coeur d’Alene announced that it would be commencing a tender offer to acquire all of the shares of Wheaton River for the same consideration as Coeur d’Alene’s merger proposal announced on June 21, 2004. Coeur d’Alene’s offer is conditional upon, among other things, Wheaton River’s shareholders not approving the IAMGold/ Wheaton River transaction.

      On June 24, 2004, the Court dismissed the motion to change the record date for the adjourned IAMGold meeting. The parties agreed to a proxy deadline of 5:00 p.m. (Toronto time) on the business day immediately prior to the adjourned IAMGold meeting.

      On June 25, 2004, IAMGold mailed the supplement to the joint circular and a directors’ circular recommending that shareholders reject the Original Offer.

      Golden Star’s board of directors met on June 28, 2004 with management and its financial and legal advisors to discuss the possible terms of an increase in the offer for IAMGold. The board considered the terms and conditions on which an increased offer might be made and sought and received advice from its legal and financial advisors regarding the proposed increase. The board approved the proposed increase in the offer. On June 28, 2004, we announced that we were increasing our Original Offer on the basis set out in this Notice of Variation.

      On June 29, 2004, Coeur d’Alene announced that it had further increased the consideration it would be offering to Wheaton River shareholders.

      On June 30, 2004, IAMGold announced that its board of directors unanimously recommended that IAMGold shareholders reject our increased offer.

      On June 30, 2004, we entered into a lock-up agreement with the holder of approximately 3.6 million IAMGold shares pursuant to which that shareholder agreed to deposit its shares under our offer and to vote its shares against the Wheaton River transaction. The shareholder has the right to terminate its obligations under the lock-up agreement in certain circumstances, including if a third party makes a fully-financed offer to acquire all of the IAMGold shares at a price per IAMGold share greater than 103% of the price per IAMGold share offered under our offer and we do not elect to increase the price offered under our offer to a price greater than or equal to the price offered under the competing offer.

5.   Manner and Time for Acceptance

      Our offer may be accepted by shareholders depositing the following documents with the depositary at the offices specified in the revised Letter of Transmittal (printed on orange paper) accompanying this Notice of Variation no later than 9:00 p.m. on July 16, 2004 (unless the expiry time is extended):

	(a)	the certificate or certificates representing the IAMGold shares in respect of which our offer is being accepted;
	(b)	a properly completed and duly signed copy of the Letter of Transmittal accompanying this Notice of Variation (printed on orange paper) (or a manually signed facsimile copy) with the signature or signatures guaranteed in accordance with the instructions set out in the Letter of Transmittal; and
	(c)	any other relevant document required by the instructions set forth in the Letter of Transmittal.

      Alternatively, shareholders may follow the procedure for guaranteed delivery set forth in Section 5 of the Offer to Purchase dated June 9, 2004, “Procedure for Guaranteed Delivery”, by using the Notice of Guaranteed Delivery (printed on yellow paper) accompanying this Notice of Variation or a manually signed facsimile thereof.

      Shareholders who have validly deposited their IAMGold shares prior to June 30, 2004 must complete and execute the revised Letter of Transmittal accompanying this Notice of Variation (printed on orange paper) to indicate whether they are electing the All Share Option or the Cash and Share Option. Shareholders who otherwise validly tender their IAMGold shares to our offer but fail to make the necessary election in the Letter of Transmittal, or to properly make such election, including those IAMGold shareholders who have previously tendered their IAMGold shares and who do not submit a revised Letter of Transmittal, will be deemed to have elected the All Share Option in respect of all of the IAMGold shares deposited under our offer.

6.   Take-Up of Deposited IAMGold Shares

      If all of the conditions referred to in Section 2 of the Offer to Purchase, “Conditions to the Offer” have been fulfilled or, where permitted, waived at the expiry time of our offer, we will take up and pay for the IAMGold shares deposited under the offer and not withdrawn no later than 10 days from the expiry date, and

7.   Payment for Deposited IAMGold Shares

      We will pay for IAMGold shares validly deposited under our offer and not withdrawn by providing the depositary with the offered consideration in the form of sufficient funds (by bank transfer or other means satisfactory to the depositary) and sufficient certificates for Golden Star shares for transmittal to persons depositing IAMGold shares under our offer. Payment of amounts with respect to the contingent payment entitlement shall be made by Golden Star when such payments are due (if at all) as set out in Section 1 of this Notice of Variation, “Increase in Price Offered for IAMGold Shares”. All amounts payable for deposited shares will be in U.S. currency in an amount determined at the time we take up and pay for shares under the offer, with respect to cash to be paid for IAMGold shares as a result of a shareholder electing the Cash and Share Option and for fractional shares, and, with respect to the contingent payment, in an amount determined at the time, if any, that we determine the contingent payment is payable.

      In the event that IAMGold declares or pays a dividend or declares, makes or pays any other distribution or payment, or declares, allots, reserves or issues any securities, rights or other interests which would result in Golden Star having the right to adjust or withhold all or part of the consideration to be paid for the IAMGold shares in accordance with Section 7 of the Offer to Purchase, “Changes in Capitalization of IAMGold; Dividends and Distributions; Liens”, we will determine, in our discretion, how any such adjustment or withholding shall be allocated between the cash portion and the share portion of the purchase price, if applicable.

8.   Right to Withdraw Deposited IAMGold Shares

      Under the terms of the offer, IAMGold shares may be withdrawn by or on behalf of a depositing shareholder (unless otherwise required or permitted by applicable law) (a) at any time prior to the expiry time of the offer; (b) at any time where the IAMGold shares have not been taken up; (c) at any time before the expiration of ten days from the date of a notice of change or variation in respect of the offer; or (d) if the shareholder’s IAMGold shares have not been paid for by us within three business days after having been taken up.

9.   Acquisition of Shares Not Deposited

      If we take up and pay for the IAMGold shares validly deposited under the offer, we intend to cause a special meeting of IAMGold shareholders to be held to effect an amalgamation (including by way of statutory arrangement) of IAMGold with Golden Star or an affiliate of Golden Star whereby we directly or indirectly will acquire all of the IAMGold shares not deposited to our offer. In any such transaction, to the extent permitted by applicable law, the non-depositing shareholders whose shares are acquired by us will receive consideration at least equal in value to and in the same form as the consideration they would have received had they deposited their IAMGold shares to our offer and selected the All Share Option.

10. Certain Canadian Federal Income Tax Considerations

          General

      In the opinion of Fasken Martineau DuMoulin LLP, counsel to Golden Star, the following is a summary, as of the date hereof, of the principal Canadian federal income tax consequences generally applicable to IAMGold shareholders who dispose of their IAMGold shares pursuant to our offer and who, for purposes of the Tax Act, hold their IAMGold shares as capital property, deal at arm’s length and are not affiliated with each of Golden Star and IAMGold at all times up to and including the completion of our offer, and immediately following completion of our offer will not, either alone or together with any person with whom the

      This summary is based upon the current provisions of the Tax Act, the regulations thereunder (the “Regulations”), all proposed amendments to the Tax Act or the Regulations announced by the Minister of Finance (Canada) prior to the date hereof and counsel’s understanding of the current published administrative and assessing practices of Canada Revenue Agency (“CRA”). This summary does not otherwise take into account or anticipate changes in the law, whether by way of judicial, governmental or legislative decision or action, nor does it take into account provincial, territorial or foreign tax legislation or considerations.

      This summary is of a general nature only and is not exhaustive of all possible Canadian federal income tax considerations. This summary is not intended to be, nor should it be construed to be, legal or tax advice to any particular IAMGold shareholder and, accordingly, IAMGold shareholders should consult their own independent tax advisors for advice with respect to the income tax consequences to them of disposing of their IAMGold shares having regard to their own particular circumstances.

          Glossary

      “Cash-Out Percentage” means the percentage equal to (100 × Cdn.$0.50)/(A + B + Cdn.$0.50) where A is the fair market value of 1.15 Golden Star shares at the time of closing expressed in Canadian dollars and B is the fair market value of the contingent payment entitlement at the time of closing expressed in Canadian dollars.

      “CPE Percentage” (i) in the case of a shareholder who accepts the offer and elects to receive consideration under the All Share Option means the percentage equal to 100% minus the Remaining Percentage, and (ii) in the case of a shareholder who accepts the offer and elects to receive consideration under the Cash and Share Option means the percentage equal to 100% minus the aggregate of the Cash-Out Percentage and the Remaining Percentage.

      “Remaining Percentage” (i) in the case of a shareholder who accepts the offer and elects to receive consideration under the All Share Option means the percentage equal to (100 × A)/(A+B); where A is the fair market value of 1.25 Golden Star shares at the time of closing expressed in Canadian dollars and B is the fair market value of the contingent payment entitlement at the time of closing expressed in Canadian dollars, and (ii) in the case of a shareholder who accepts the offer and elects to receive the Cash and Share Option means the percentage equal to (100 × A)/(A + B + Cdn.$0.50); where A is the fair market value of 1.15 Golden Star shares at the time of closing expressed in Canadian dollars and B is the fair market value of the contingent payment entitlement at the time of closing expressed in Canadian dollars.

          Shareholders Resident in Canada

      In addition to the comments set out under the heading “General,” this portion of the summary is applicable only to IAMGold shareholders who are resident or deemed to be resident in Canada for purposes of the Tax Act (“Resident Shareholder”).

      Certain Resident Shareholders whose IAMGold shares might not otherwise qualify as capital property may, in certain circumstances, make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have their IAMGold shares and every “Canadian security” (as defined in the Tax Act) owned by such holders in the taxation year of the election and in all subsequent taxation years deemed to be a capital property.

          Resident Shareholders Accepting the Offer — All Share Option

      The following applies only to a Resident Shareholder who accepts our offer and elects the All Share Option on the basis that the Remaining Percentage of each IAMGold share will be exchanged with Golden Star for 1.25 Golden Star shares and the CPE Percentage of each IAMGold share will be exchanged for the contingent payment entitlement discussed under Section 1 above “Increase in Price Offered for IAMGold Shares”. Golden Star believes this allocation to be reasonable; however, such allocation is not binding upon the CRA. If the foregoing allocation is ultimately changed, the tax consequences described below would have to be modified to take into account such variance.

      Under the current administrative practices of the CRA, as set out in Interpretation Bulletin No. IT-450R:

	(a)	a Resident Shareholder will be considered

	(i)	to have disposed of the Remaining Percentage of each IAMGold share for proceeds of disposition equal to the Remaining Percentage of the Resident Shareholder’s adjusted cost base of such IAMGold share determined immediately before the exchange, with the result that no capital gain or loss will be realized by the Resident Shareholder on such disposition, and
	(ii)	to have acquired the Golden Star shares at a cost equal to the Remaining Percentage of the Resident Shareholder’s adjusted cost base of the IAMGold shares disposed of,

unless the Resident Shareholder, in the income tax return for the taxation year in which the exchange occurs, includes in computing income any portion of the gain or loss otherwise determined on such exchange; in which case the Resident Shareholder will be required to recognize a capital gain (or a capital loss) to the extent that the fair market value at the time of the exchange of the Golden Star shares exceeds (or is less than) the total of the Remaining Percentage of the Resident Shareholder’s adjusted cost base of the IAMGold shares and any reasonable costs of disposition and the Resident Shareholder will be considered to have acquired the Golden Star shares at a cost equal to the fair market value at the time of the exchange of the Remaining Percentage of the IAMGold share;

	(b)	a Resident Shareholder will be considered to have disposed of the CPE Percentage of each IAMGold share for proceeds of disposition equal to the fair market value of the contingent payment entitlement at the time it is acquired with the result that the Shareholder will realize a capital gain (or a capital loss) in respect of the CPE Percentage of the IAMGold share to the extent that such proceeds of disposition exceed (or are less than) the total of the CPE Percentage of the adjusted cost base of the IAMGold share held by such shareholder and any reasonable costs of disposition. To the extent that the Resident Shareholder receives payment under the contingent payment entitlement that is less than (or greater than) the fair market value of the contingent payment entitlement at the time it was acquired, such shareholder will realize a capital loss (or a capital gain) equal to such amount; and
	(c)	a Resident Shareholder who receives cash not exceeding Cdn.$200 in lieu of a fractional share will have the option of recognizing the capital gain or capital loss arising on the disposition of the fractional share or, alternatively, of reducing the adjusted cost base of the Golden Star shares acquired by the amount of cash so received.

          Resident Shareholders Accepting the Offer — Cash and Share Option

      The following applies only to a Resident Shareholder who accepts our offer and elects the Cash and Share Option on the basis that the Remaining Percentage of each IAMGold share will be exchanged with Golden Star for 1.15 Golden Star Shares, the Cash-Out Percentage of each IAMGold share will be exchanged for $0.50, and the CPE Percentage of each IAMGold share will be exchanged for the contingent payment entitlement. Golden Star believes this allocation to be reasonable; however, such allocation is not binding upon

	(ii)	to have acquired the Golden Star shares at a cost equal to the Remaining Percentage of the Resident Shareholder’s adjusted cost base of the IAMGold shares disposed of,

unless the Resident Shareholder, in the income tax return for the taxation year in which the exchange occurs, includes in computing income any portion of the gain or loss otherwise determined on such exchange; in which case the Resident Shareholder will be required to recognize a capital gain (or a capital loss) to the extent that the fair market value at the time of the exchange of the Golden Star shares exceeds (or is less than) the total of the Remaining Percentage of the Resident Shareholder’s adjusted cost base of the IAMGold shares and any reasonable costs of disposition and the Resident Shareholder will be considered to have acquired the Golden Star shares at a cost equal to the fair market value at the time of the exchange of the Remaining Percentage of the IAMGold share;

	(b)	a Resident Shareholder will be considered to have disposed of the Cash-Out Percentage of each IAMGold share for proceeds of disposition equal to the amount of cash received for the Cash-Out Percentage of the IAMGold share with the result that the Resident Shareholder will realize a capital gain (or a capital loss) in respect of the Cash-Out Percentage of the IAMGold share to the extent that such proceeds of disposition exceed (or are less than) the total of the Cash-Out Percentage of the adjusted cost base of the IAMGold share held by such shareholder and any reasonable costs of disposition;

To the extent that the Resident Shareholder receives payment under the contingent payment entitlement that is less than (or greater than) the fair market value of the contingent payment entitlement at the time it was acquired, such shareholder will realize a capital loss (or a capital gain) equal to such amount; and

          Taxation of Capital Gains and Capital Losses

      One-half of any capital gain (a “taxable capital gain”) realized pursuant to our offer must be included in computing the Resident Shareholder’s income and one-half of any capital loss (an “allowable capital loss”) incurred pursuant to our offer is deductible by the Resident Shareholder from taxable capital gains arising in the year of disposition. To the extent that a Resident Shareholder has insufficient taxable capital gains in the

Table of Contents

      The amount of any capital loss realized by a Resident Shareholder that is a corporation or certain partnerships or trusts may be reduced in certain circumstances in respect of dividends previously received or deemed to be received on the IAMGold shares to the extent and under the circumstances described in the Tax Act.

      A Resident Shareholder who is an individual (other than certain trusts) who realizes a capital gain may be subject to alternative minimum tax.

      A Resident Shareholder that is throughout the relevant taxation year a “Canadian-controlled private corporation” as defined in the Tax Act may be liable to pay, in addition to the tax otherwise payable under the Tax Act, a refundable tax of 6 2/3% determined by reference to its aggregate investment income for the year, which is defined to include an amount in respect of taxable capital gains.

          Acquisition of Shares Not Deposited

      A Resident Shareholder who dissents and elects to receive the fair value for the holder’s IAMGold shares will be considered to have disposed of the IAMGold shares for proceeds of disposition equal to the amount received by the Resident Shareholder less the amount of interest awarded by the Court and will realize a capital gain (or a capital loss) in the manner, and subject to the treatment, described above. Any interest awarded to the Resident Shareholder by the Court will be included in the Resident Shareholder’s income for the purposes of the Tax Act.

          Subsequent Acquisition Transaction

      As described in Section 5 of the Circular, “Acquisition of Shares Not Deposited — Subsequent Acquisition Transaction”, as varied by this Notice of Variation, if the Offeror does not acquire all of the IAMGold shares pursuant to the Offer, the Offeror proposes to carry out a Subsequent Acquisition Transaction by means of an amalgamation. On such amalgamation a Shareholder may receive non-share consideration in the form of cash or a Contingent Payment Entitlement. If a Resident Shareholder receives such non-share consideration, on the amalgamation such shareholder will be considered to have disposed of their IAMGold shares for proceeds of disposition equal to the aggregate fair market value of all the consideration received at the time it is acquired with the result that such Resident Shareholder will realize a capital gain (or a capital loss) to the extent that such proceeds of disposition exceed (or are less than) the aggregate adjusted cost base of the IAMGold shares held by such shareholder immediately prior to the amalgamation and any reasonable costs of disposition. If the sole consideration received by a Resident Shareholder on the amalgamation is shares of the amalgamated corporation, such shareholder will be deemed to have disposed of the IAMGold shares for proceeds equal to the adjusted cost base to the shareholder of such shares immediately before the amalgamation and to have acquired the shares of the amalgamated corporation at a cost equal to such deemed proceeds.

      If the Subsequent Acquisition Transaction is not carried out as an amalgamation as described above, the tax treatment of such transaction to a Resident Shareholder will depend upon the exact manner in which the Subsequent Acquisition Transaction is carried out.

      Resident Shareholders should consult their own tax advisors for advice with respect to the income tax consequences to them of having their IAMGold shares acquired pursuant to a Subsequent Acquisition Transaction.

Table of Contents

          Non-Resident Shareholders Accepting the Offer

      A Non-Resident Shareholder who accepts our offer and elects under either the All Share Option or the Cash and Share Option will not be subject to tax under the Tax Act in respect of any capital gain realized on a disposition of IAMGold shares pursuant to the offer unless such shares are or are deemed to be “taxable Canadian property” and the Non-Resident Shareholder is not afforded any relief under an applicable tax treaty.

      Generally, IAMGold shares will not be taxable Canadian property at a particular time provided that such shares are listed on a prescribed stock exchange (which includes the TSX and the AMEX), unless:

	(a)	at any time during the five year period immediately preceding the disposition of the IAMGold shares by such Non-Resident Shareholder, the Non-Resident Shareholder, persons not dealing at arm’s length with such Non-Resident Shareholder, or any combination thereof owned (or had options to acquire) not less than 25% of the issued shares of any class or series of the capital stock of IAMGold; or
	(b)	the Non-Resident Shareholder’s IAMGold shares were acquired in a tax deferred exchange in consideration for property that was itself taxable Canadian property.

      Even if the IAMGold shares are taxable Canadian property to a Non-Resident Shareholder and the disposition would give rise to a capital gain, an exemption from tax may be available under the terms of an applicable income tax treaty between Canada and the country of residence of the Non-Resident Shareholder.

          Acquisition of Shares Not Deposited

      The consequences under the Tax Act to a Non-Resident Shareholder of any subsequent acquisition transaction would depend upon the nature of the transaction. In general, the Non-Resident Shareholder would not be subject to taxation under the Tax Act in respect of any capital gain that is recognized, including on the proposed amalgamation, unless the Non-Resident Shareholder’s IAMGold shares are taxable Canadian property, as described above, and the Non-Resident Shareholder is not afforded any relief under an applicable tax treaty.

      A Non-Resident Shareholder who dissents and elects to receive the fair value for the holder’s IAMGold shares will be considered to have disposed of the IAMGold shares for proceeds of disposition equal to the amount received by the Resident Shareholder less the amount of interest awarded by the Court. In such circumstances, the Non-Resident Shareholder would not be subject to taxation under the Tax Act in respect of any capital gain that is recognized unless the Non-Resident Shareholder’s IAMGold shares are taxable Canadian property, as described above, and the Non-Resident Shareholder is not afforded any relief under an applicable tax treaty.

      Interest awarded to a dissenting Non-Resident Shareholder by a court will be subject to non-resident withholding tax at the rate of 25% unless the rate is reduced under the provisions of an applicable tax treaty.

      Non-Resident Shareholders should consult their own tax advisors for advice with respect to the potential income tax consequences to them of having their IAMGold shares acquired pursuant to a subsequent acquisition transaction.

11.	Certain U.S. Income Tax Considerations

      The following is a summary of the material anticipated U.S. Federal income tax consequences of exchanging IAMGold shares for our common shares pursuant to the offer. This summary is based upon the U.S. Internal Revenue Code of 1986, as amended, referred to as the “Code,” treasury regulations promulgated under the Code, administrative rulings of the U.S. Internal Revenue Service, referred to as the “IRS”, and judicial decisions of the U.S. courts, in each case as in effect on the date hereof. Changes in the laws may alter

Table of Contents

      This summary is general in nature and does not address the effects of any state or local taxes, or the tax consequences in jurisdictions other than the United States. In addition, this summary does not address all U.S. Federal income tax consequences that may be relevant to the particular circumstances of a holder of IAMGold shares, nor to a holder of IAMGold shares with a special status, such as:

	•	a person that owns, has owned, or will own 5% or more (by voting power or value, and taking into account certain attribution rules) of our issued and outstanding shares or IAMGold shares;
	•	a broker, dealer or trader in securities or currencies, or any person who owns IAMGold shares or our shares other than as capital assets within the meaning of Section 1221 of the Code;
	•	a bank, mutual fund, life insurance company or other financial institution;
	•	a tax-exempt organization;
	•	a real estate investment trust or regulated investment company;
	•	a qualified retirement plan or individual retirement account;
	•	a person that holds or will hold their IAMGold shares or Golden Star shares as part of a straddle, hedge, constructive sale or other integrated transaction for tax purposes;
	•	a partnership, S corporation or other “pass-through” entity, as determined for U.S. Federal income tax purposes;
	•	an investor in a partnership, S corporation or other “pass-through” entity, as determined for U.S. Federal income tax purposes;
	•	a person whose functional currency for tax purposes is not the U.S. dollar;
	•	a person liable for alternative minimum tax.

      It is assumed for purposes of this summary that we are not, have not at any time been and will not be after this offering (a) a “controlled foreign corporation,” as defined in Section 957(a) of the Code, (b) a “foreign investment company,” as defined in Section 1246(b) of the Code or (c) a “foreign personal holding company,” as defined in Section 552 of the Code.

      HOLDERS OF IAMGOLD SHARES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE ACQUISITION PURSUANT TO THE OFFER, OWNERSHIP AND DISPOSITION OF OUR SHARES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS THE TAX CONSEQUENCES UNDER STATE, LOCAL AND NON-UNITED STATES TAX LAW AND THE POSSIBLE EFFECTS OF CHANGES IN TAX LAW.

      For purposes of this discussion, a “U.S. Holder” means a beneficial owner of a common share of IAMGold, or Golden Star, as the case may be, who is, for U.S. Federal income tax purposes:

	•	an individual citizen or resident of the United States;
	•	a corporation created or organized in or under the laws of the United States or any political subdivision thereof;
	•	an estate the income of which is subject to U.S. Federal income taxation regardless of its source; or
	•	a trust (1) that validly elects to be treated as a U.S. person for U.S. Federal income tax purposes or (2) the administration over which a U.S. court can exercise primary supervision and all of the substantial decisions of which one or more U.S. persons have the authority to control.

      “Non-U.S. Holder” means any person who owns shares of IAMGold, or our shares, as the case may be, and who is not a U.S. Holder.

      If a “pass-through” entity holds IAMGold shares, the tax treatment of an owner of such “pass-through” entity generally will depend upon the status of such owner and upon the activities of the “pass-through” entity. An owner of a “pass-through” entity holding IAMGold shares should consult such owner’s tax advisor regarding the specific tax consequences of exchanging IAMGold shares in the offer.

U.S. Holders of IAMGold Shares

	Consequences of Exchanging IAMGold Shares Pursuant to the Offer

      Following the closing of the offer, we intend to effect the subsequent amalgamation of IAMGold and Golden Star or an affiliate of Golden Star, pursuant to which U.S. Holders of IAMGold shares who do not exchange their shares in the offer will receive Golden Star shares and may receive a cash payment. See Section 5 of the Circular, “Acquisition of Shares Not Deposited”, as amended by this Notice of Variation. We will endeavor to cause the exchange of IAMGold shares pursuant to the offer together with the subsequent amalgamation to be treated as an exchange pursuant a “reorganization” within the meaning of Section 368(a)(1) of the Code. However, reorganization treatment may or may not be available, depending upon the specific outcome of the subsequent amalgamation. Moreover, reorganization treatment will apply only if the offer and the subsequent amalgamation are treated for federal tax purposes as a single transaction. While we intend to treat the offer and the subsequent amalgamation in this manner, our treatment will not bind the Internal Revenue Service. Accordingly, even if we succeed in effecting the subsequent amalgamation of IAMGold and Golden Star or an affiliate of Golden Star after the closing of the offer, there may be some risk that the exchange of IAMGold shares pursuant to the offer will not be treated as made pursuant to a “reorganization” under Section 368(a)(1) of the Code. Each U.S. Holder is urged to take this risk into account.

      If the exchange of IAMGold shares pursuant to the offer qualifies as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code, the exchange should have the following U.S. Federal income tax consequences:

	•	Golden Star and IAMGold will be treated as “parties to the reorganization” under Section 368(b) of the Code.
	•	No gain or loss will be recognized on the exchange of IAMGold shares solely for Golden Star shares pursuant to the offer, except with respect to cash received instead of a fractional share;
	•	Gain (but not loss) will be recognized on the exchange of IAMGold shares for a combination of IAMGold shares and cash pursuant to the offer, equal in amount to the excess, if any, of:

	•	the amount realized, including the sum of the cash (excluding any cash received instead of a fractional Golden Star share) and the fair market value of the Golden Star shares received (including any fractional Golden Star share deemed received and exchanged for cash), over
	•	the U.S. Holder’s adjusted tax basis in the IAMGold shares exchanged,

	but not in excess of the cash received by such U.S. holder in the transaction.
	Such gain would generally be capital gain, and would generally be long term capital gain if the IAMGold shares were held for more than one year. However, in certain circumstances in which the U.S. Holder maintains a sufficient continuing interest (both direct and constructive) in Golden Star, the gain could be treated as dividend income to the extent paid out of current or accumulated earnings and profits of Golden Star. A U.S. Holder who exchanges IAMGold shares that have different bases must compute gain separately on the separate shares.

	•	The aggregate adjusted tax basis of our shares received in the exchange (including any fractional share deemed received and exchanged for cash) by a U.S. Holder will be the same as the aggregate adjusted tax basis of such U.S. Holder’s IAMGold shares exchanged therefore, increased by the amount of gain recognized in the exchange (other than gain recognized on the receipt of cash in lieu of a fractional share) and reduced by the amount of cash received in the exchange.

21

Table of Contents

	•	The holding period of our shares received in the exchange by a U.S. Holder will include the holding period of such U.S. Holder’s IAMGold shares exchanged therefore.
	•	The receipt of cash in lieu of a fractional Golden Star share by a U.S. Holder will generally result in taxable gain or loss to the U.S. Holder equal to the difference between the amount of cash received by the U.S. Holder and the U.S. Holder’s adjusted tax basis in such fractional share. Such gain or loss will be capital gain or loss and will be long-term capital gain or loss if the U.S. Holder’s holding period exceeds one year upon the closing of the exchange. However, in certain circumstances in which a U.S. Holder maintains a sufficient interest in Golden Star (both direct and constructive), the amount of a cash payment received in lieu of a fractional share by the U.S. Holder may be treated as dividend income to the extent paid out of earnings and profits.
	•	The contingent payment of Cdn.$0.20 per share, if and when received, less any portion of the payment that is treated for federal income tax purposes as interest, will be treated as an additional amount realized that would result in the recognition of additional gain, if any.
	•	Alternatively, there is a possibility that the fair market value of the right to receive the contingent payment of Cdn.$0.20 will be treated as an additional amount realized at the time of the exchange which would result in the recognition of additional gain, if any, at that time. In this case, the U.S. Holder would also recognize income or gain when the Cdn.$0.20 is received or becomes payable or would recognize loss if and when the right to receive the payment becomes worthless. Any such additional income or gain may represent ordinary income rather than capital gain. The deductibility of any such loss may be limited.
	•	Upon receipt by a U.S. Holder of a contingent payment of Cdn$0.20 per share, a portion of such payment may be taxed to the U.S. Holder as ordinary income in the nature of interest.

      U.S. Holders of IAMGold shares who have acquired different lots of IAMGold shares for different prices per share should consult with their U.S. tax advisors to determine whether they may identify specific lots of our shares as received in exchange for the different lots of IAMGold shares.

      If the exchange of IAMGold shares for our shares fails to qualify as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code, a U.S. Holder will recognize taxable gain or loss equal to the difference between the amount realized in the exchange and the U.S. Holder’s adjusted basis in the IAMGold shares exchanged. Any such gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder’s holding period in the IAMGold shares exceeds one year upon the consummation of the exchange pursuant to the offer. The contingent payment of Cdn.$0.20 per share, less any portion of this payment that is treated for federal income tax purposes as interest, will be treated as an additional amount realized if and when received. Alternatively, there is a possibility that the fair market value of the right to receive the contingent payment will be treated as an additional amount realized at the time of the exchange, in which case additional ordinary income may be realized when the Cdn.$0.20 is received or becomes payable and loss may be realized when the right becomes worthless. A U.S. Holder’s adjusted basis in the Golden Star shares received in the exchange would be equal to their fair market value as of the date of the exchange, and the U.S. Holder’s holding period for the Golden Star shares would commence on the day following the exchange. Various provisions of the Code may apply in some circumstances to limit the utilization of loss, if any, recognized by certain taxpayers.

      For non-corporate U.S. Holders, long-term capital gain recognized in connection with an exchange made pursuant to the offer generally will be taxed at a maximum U.S. Federal income tax rate of 15% as compared with a maximum rate of 35% for ordinary income. The deductibility of capital losses is subject to limitations. Any gain recognized in the exchange will generally have a U.S. source for foreign tax credit purposes, except any portion of such gain that is treated as dividend income.

      The tax consequences described above are based upon the assumption that IAMGold is not, and has not been, a passive foreign investment company referred to as a “PFIC.” If IAMGold were a PFIC for the taxable year that includes any portion of a U.S. Holder’s holding period in IAMGold shares, the tax consequences to

	•	if the exchange is in pursuance of a reorganization under Section 368(a)(1) of the Code, the U.S. Holder would recognize gain (but not loss) on the exchange of IAMGold shares pursuant to the offer, and would recognize gain or loss, or, in some circumstances, dividend income, on the receipt of cash in lieu of fractional shares, with all such gain or income treated as ordinary income; and
	•	if the exchange does not qualify as a reorganization under Section 368(a)(1) of the Code, the U.S. Holder would recognize gain or loss, with such gain treated as ordinary income.

In either case, any such gain or income would be subject to tax as an “excess distribution” at the highest marginal rates applicable to ordinary income, and would be subject to interest charges to reflect the value of the U.S. income tax deferral, unless the U.S. Holder has timely made an election to mark the IAMGold shares to market or to treat IAMGold as a “qualified electing fund.”

	Transfer of IAMGold Shares Not Exchanged Pursuant to the Offer

      We plan to effect an amalgamation of IAMGold with Golden Star or an affiliate of Golden Star following the closing of the offer. The consequences to a U.S. Holder of the subsequent amalgamation will depend upon the consideration issued by Golden Star in the amalgamation. To the extent the IAMGold shares are acquired by us for our shares and/or cash, the consequences to a U.S. Holder should generally be similar to the consequences to a U.S. Holder of exchanging IAMGold shares for our shares pursuant to the offer. Such consequences will depend upon whether the exchange qualifies as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code. See “U.S. Holders of IAMGold Shares — Consequences of Exchanging IAMGold Shares Pursuant to the Offer,” above.

      A U.S. Holder that exercises dissent rights and receives cash for its IAMGold shares will recognize gain or loss based on the difference between the cash received and the holder’s adjusted tax basis in the IAMGold shares exchanged. Any such gain or loss would generally be treated as capital gain or loss, and as long-term capital gain or loss if the IAMGold shares were held for more than one year.

	Reporting Requirements

      A U.S. Holder of IAMGold shares receiving Golden Star shares pursuant to the offer or pursuant to the subsequent amalgamation of IAMGold may be required to retain records related to such U.S. Holder’s IAMGold shares, and file with its Federal income tax return a statement setting forth facts relating to the transaction.

	Distributions on Golden Star Shares

      Subject to the discussion under “Passive Foreign Investment Company” below, the gross amount of distributions, if any, payable on our shares generally will be treated as a foreign source dividend to the extent paid out of current or accumulated earnings and profits, and generally will be “passive income” for U.S. foreign tax credit purposes. A distribution on our shares in excess of current or accumulated earnings and profits will be treated as a tax-free return of capital to the extent of the U.S. Holder’s adjusted tax basis in such shares and, to the extent in excess of adjusted basis, as capital gain. See “Sale or Other Disposition of Golden Star Shares,” below.

      Canadian withholding tax on dividend distributions paid by us to a U.S. Holder is generally reduced to 15% pursuant to the U.S.-Canada tax treaty in the case of U.S. Holders who are eligible for benefits under the U.S.-Canada tax treaty. U.S. Holders generally may treat the amount of any Canadian income taxes withheld from distributions with respect to the common shares either as a deduction from their gross income or as a dollar-for-dollar credit against their U.S. Federal income tax liability, subject to numerous and complex limitations and restrictions, which must be determined and applied on an individual basis by each U.S. Holder. Accordingly, you should consult your own tax advisor concerning the foreign tax credit rules in your particular circumstances.

Table of Contents

	Sale or Other Disposition of Golden Star Shares

      Subject to the discussion below under “Passive Foreign Investment Company,” a U.S. Holder who sells or otherwise disposes of our shares in a taxable disposition will recognize gain or loss equal to the difference, if any, between the U.S. dollar value of the amount realized on such sale or other taxable disposition and the U.S. Holder’s adjusted tax basis in such shares. Any such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the holding period for our shares is more than one year at the time of the sale or other disposition. Any such gain or loss will generally be treated as U.S. source income for U.S. foreign tax credit purposes, although special rules apply to U.S. Holders who have a fixed place of business outside the United States to which the gain is attributable. Special considerations may apply to a U.S. Holder who receives foreign currency in connection with a sale or other taxable disposition of our shares.

	Passive Foreign Investment Company

      If Golden Star were or were to become a PFIC for U.S. Federal income tax purposes, U.S. Holders of our shares would be subject to a special, adverse tax regime (different in significant respects from that described above). If we were, or were to become, a PFIC for any year in which a U.S. Holder owns our shares, gain on a disposition or deemed disposition by the U.S. Holder of our shares, and the amount of “excess distributions”, if any, payable on our shares, would be subject to tax at the highest marginal rates applicable to ordinary income, and would be subject to interest charges to reflect the value of the U.S. income tax deferral, unless the U.S. Holder has timely made a “mark-to-market” election or a “qualified electing fund” election. In general terms, we will be a PFIC for any tax year in which either (i) 75% or more of our gross income is passive income or (ii) the average percentage, by fair market value, of our assets that produce or are held for the production of passive income is 50% or more. “Passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

      We do not believe that we are, nor do we expect to become, a PFIC. However, there can be no assurance that our determination concerning our PFIC status will not be challenged by the IRS. There is also a possibility that we could become a PFIC in the future as a result of future financial results.

Non-U.S. Holders

	Consequences of Exchanging IAMGold Shares Pursuant to the Offer

      If the exchange of IAMGold shares for our shares pursuant to the offer qualifies as an exchange pursuant a “reorganization” within the meaning of Section 368(a)(1) of the Code, Non-U.S. Holders generally will not recognize gain or loss for U.S. Federal income tax purposes upon the receipt of our shares in the exchange. However, a Non-U.S. Holder may recognize gain, if any, to the extent of cash received in the exchange, on the receipt of the contingent payment of Cdn.$0.20 per share and/or on the right to receive such payment, and on the receipt of cash in lieu of fractional Golden Star shares, if either of the following conditions applies:

	•	Such gain is attributable to an office or other fixed place of business in the United States and, if a treaty applies, such gain is attributable to a permanent establishment or fixed base the Non-U.S. Holder maintains in the United States; or
	•	The Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of disposition, or has a tax home in the United States, and certain other requirements are met.

      If the exchange of IAMGold shares for our shares fails to qualify as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code, a Non-U.S. Holder generally would not recognize gain on the exchange for U.S. Federal income tax purposes unless either one of the two conditions described immediately above is satisfied.

Table of Contents

	Acquisition of IAMGold Shares Not Exchanged Pursuant to the Offer

      We plan to effect an amalgamation of IAMGold with Golden Star or an affiliate of Golden Star following the closing of the offer. The consequences to a Non-U.S. Holder of the subsequent amalgamation will depend upon the consideration issued in the subsequent amalgamation. To the extent the IAMGold shares are acquired for our shares and/or cash, the consequences to a Non-U.S. Holder should generally be similar to the consequences to a Non-U.S. Holder of exchanging IAMGold shares for our shares and/or cash pursuant to the offer. Such consequences will depend in part upon whether the exchange qualifies as an exchange pursuant to a reorganization under Section 368(a)(1) of the Code. See “Non-U.S. Holders — Consequences of Exchanging IAMGold shares Pursuant to the Offer.”

      A Non-U.S. Holder that exercises dissent rights and receives cash for its IAMGold shares will recognize gain (based on the difference between the cash received and the holder’s adjusted tax basis in the IAMGold shares exchanged) only if one of the two conditions apply that are described (and bulleted) in the discussion captioned “Non-U.S. Holders — Consequences of Exchanging IAMGold Shares Pursuant to the Offer.”

	Sale or Other Disposition of Golden Star Shares

      In general, a Non-U.S. Holder will not be subject to U.S. Federal income tax on any gain realized upon the sale or other disposition of our shares unless:

	•	Such gain is attributable to an office or other fixed place of business in the United States and, if a treaty applies, such gain is attributable to a permanent establishment or fixed base the Non-U.S. Holder maintains in the United States; or
	•	The Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of disposition, or has a tax home in the United States, and certain other requirements are met.

Information Reporting and Backup Withholding

      U.S. Holders of IAMGold shares may be subject to information withholding and may be subject to backup withholding, currently at up to a 28% rate, on cash payments received in exchange for IAMGold shares pursuant to the offer. Payments of distributions on, or the proceeds from a sale or other disposition of, our shares paid within the U.S. may be subject to information reporting and may be subject to backup withholding. Payments of distributions on, or the proceeds from the sale of, our shares to or through a foreign office of a broker generally will not be subject to backup withholding, although information reporting may apply to those payments in certain circumstances.

      Backup withholding will generally not apply, however, to a U.S. Holder who:

	•	furnishes a correct taxpayer identification number and certifies that he, she or it is not subject to backup withholding on the IRS Form W-9 (or substitute form); or
	•	is otherwise exempt from backup withholding.

      Non-U.S. Holders generally will not be subject to U.S. information reporting or backup withholding. However, such holders may be required to provide certification of non-U.S. status (generally, on IRS Form W-8BEN) in connection with payments received in the United States or through certain U.S.-related financial intermediaries.

      Backup withholding is not an additional tax. Any amounts withheld from a payment to a holder under the backup withholding rules may be credited against the holder’s U.S. Federal income tax liability, and a holder may obtain a refund of any excess amounts withheld by filing the appropriate claim for refund with the IRS in a timely manner and furnishing any required information.

PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS OF

COMPILATION REPORT

To the Directors of Golden Star Resources Ltd.

We have read the accompanying unaudited pro forma consolidated balance sheet of Golden Star Resources Ltd. (the “Company”) as at March 31, 2004 and unaudited pro forma consolidated statements of operations for the three month period then ended, and for the year ended December 31, 2003, all of which have been prepared in accordance with Canadian Generally Accepted Accounting Principles. We have performed the following procedures.

	1.	Compared the figures in the columns captioned “Golden Star Resources Ltd.” to the consolidated financial statements of Golden Star Resources Ltd. as at March 31, 2004 and for the three month period then ended, and found them to be in agreement, or recalculated those figures based on information in such consolidated financial statements, and found the amounts to be arithmetically correct.
	2.	Compared the figures in the columns captioned “IAMGold Corporation” to the consolidated financial statements of IAMGold Corporation as at March 31, 2004 and for the three month period then ended, and found them to be in agreement, or recalculated those figures based on information in such consolidated financial statements, and found the amounts to be arithmetically correct.
	3.	Compared the figures in the column captioned “Golden Star Resources Ltd.” to the consolidated financial statements of Golden Star Resources Ltd. for the year ended December 31, 2003, and found them to be in agreement, or recalculated those figures based on information in such audited consolidated financial statements, and found the amounts to be arithmetically correct.
	4.	Compared the figures in the column captioned “IAMGold Corporation” to the audited consolidated financial statements of IAMGold Corporation for the year ended December 31, 2003, and found them to be in agreement, or recalculated those figures based on information in such audited consolidated financial statements, and found the amounts to be arithmetically correct.
	5.	Made enquiries of certain officials of the Company who have responsibility for financial and accounting matters about:

	a.	the basis for determination of the pro forma adjustments; and
	b.	whether the pro forma consolidated financial statements comply as to form in all material respects with the securities acts of the provinces and territories of Canada (the “Acts”) and the related regulations.

            The officials:

	a.	described to us the basis for determination of the pro forma adjustments; and
	b.	stated that the pro forma consolidated financial statements comply as to form in all material respects with the Acts and related regulations.

	6.	Read the notes to the pro forma consolidated financial statements, and found them to be consistent with the basis described to us for determination of the pro forma adjustments.
	7.	Recalculated the application of the pro forma adjustments to the aggregate of the amounts in the columns captioned “Golden Star Resources Ltd.” and “IAMGold Corporation” as at March 31, 2004 and for the three month period then ended and found the amounts in the column captioned “Pro Forma Consolidated” to be arithmetically correct.

		December 31, 2003 and found the amounts in the column captioned “Pro Forma Consolidated” to be arithmetically correct.

      These pro forma consolidated financial statements are based on management’s assumptions and adjustments, which are inherently subjective. The foregoing procedures are substantially less than either an audit or a review, the objective of which is the expression of assurance with respect to management’s assumptions, the pro forma adjustments, and the application of the adjustments to the historical financial information. Accordingly, we express no such assurance. The foregoing procedures would not necessarily reveal matters of significance to the pro forma condensed consolidated financial statements, and we therefore make no representation about the sufficiency of the procedures for the purposes of a reader of such statements.

PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS OF GOLDEN STAR RESOURCES LTD.

DESCRIPTION OF OFFER TO PURCHASE IAMGOLD CORPORATION

      Golden Star Resources Ltd. (“Golden Star”, the “Company”, “us”, “we”) announced on May 27, 2004 a proposed business combination with IAMGold Corporation (“IAMGold”). On June 28, 2004 we increased our offer to exchange 1.15 Golden Star common shares for each common share of IAMGold, to an exchange ratio of 1.25 Golden Star shares or 1.15 Golden Star shares plus Cdn$0.50 cash per IAMGold share. Assuming that all IAMGold shareholders elect the all share option, the offer would result in the issuance of approximately 186.6 million Golden Star shares, and assuming that all IAMGold shareholders elect the cash and share option, the offer would result in the issuance of approximately 171.7 million Golden Star shares, each for approximately 149.3 million IAMGold common shares (assuming all in-the-money options to purchase IAMGold common shares are exercised). In addition, Golden Star will pay a further Cdn$0.20 in cash per IAMGold share to the IAMGold shareholders in the event that no break fee is paid or becomes payable to Wheaton River Minerals Ltd.

      Assuming that all IAMGold shareholders elect the all share option and that all IAMGold shares are exchanged in this offer, immediately following the exchange, approximately 46% of the shares would be held by current Golden Star shareholders and approximately 54% of the shares would be held by current IAMGold shareholders, calculated on a fully diluted basis. As the relative share ownership of the two groups of shareholders is similar, it is expected that Golden Star’s board of directors and management will retain their positions in the combined entity and Golden Star’s corporate office will continue to be the headquarters of the combined entity, Golden Star is considered to be the acquirer for the purposes of purchase accounting. In accordance with this assumption, IAMGold’s assets and liabilities have been restated in the pro forma financial statements presented below, to reflect their estimated fair values as of the date of the announcement of the proposed acquisition.

      The pro forma financial statements are based upon a Golden Star common share price of $5.10, this amount being the average closing common share price of Golden Star three days before and after the day of the date of the public announcement of Golden Star’s proposed business combination with IAMGold.

      As a consequence of the nature of the transaction, there may be, and likely will be, actions and other events or changes initiated by IAMGold that would significantly change purchase prices and purchase price allocations. Also, Golden Star has not had access to proprietary and confidential corporate financial and other information of IAMGold and has not had an opportunity to undertake any due diligence procedures. Such information and procedures may provide Golden Star with additional information that could materially affect the purchase price paid for the acquisition of IAMGold, the purchase price allocation and, accordingly, the assumptions and pro forma adjustments. Identified factors which may have a significant impact on the basis and results of the combinations are described in Note 3 of the accompanying notes to the Pro Forma Consolidated Financial Statements.

      The combination of Golden Star and IAMGold is subject to, among other things, regulatory approval. The fair value of IAMGold’s assets and liabilities will ultimately be determined after the completion of the transaction. Therefore, it is likely that the fair values of assets and liabilities will vary from those shown and the differences may be material.

      The preliminary allocation of the purchase price ($000s) summarized in the table below is subject to change:

Purchase price
	149,266,712 IAMGold shares (1)		$	950,953
	Estimated acquisition costs			10,000
			$	960,953

	Cash and cash equivalents(2)		$	49,357
	Non-cash working capital			72,560

	Equity investments in mine properties			77,000
	Royalty interests			78,000
	Property, plant and equipment			116,382

	Rehabilitation provision			(6,034	)
	Long-term debt			(11,399	)
	Future income taxes, net			(53,707	)
	Share purchase loans			266
	Deferred stock-based compensation			3,748
			$	960,953

1.	The amount shown is an estimated price based on the number of IAMGold shares outstanding on June 4, 2004 and assumes that all IAMGold shareholders elect the all share option rather than the cash and share option, and assumes the exercise of all IAMGold options where the market price on June 28, 2004 exceeds such option’s exercise price, or “in-the-money” IAMGold options. The contingent payment of Cdn$0.20 is not included in the purchase price calculation.
2.	The allocation shown above assumes IAMGold will pay a $23 million break fee to Wheaton River. If Wheaton River were to combine with Coeur d’Alene, we would then receive a $26 million payment in lieu of the break fee from Coeur d’Alene per an agreement between us and Coeur d’Alene. See “Pre-Offer Agreement with Coeur d’Alene.” If we receive the $26 million payment from Coeur d’Alene, our cash would be $49 million higher and the goodwill would be $49 million lower than shown above.

BASIS OF PRESENTATION

      Set out below are the unaudited consolidated pro forma statements of operation for the year ended December 31, 2003 and three months ended March 31, 2004 and the unaudited consolidated pro forma balance sheet of Golden Star at March 31, 2004. These statements have been prepared by the management of Golden Star to assist you in your analysis of the financial effects of the proposed business combination of Golden Star and IAMGold.

      The Golden Star information has been derived from our historical unaudited financial statements as of and for the three months ended March 31, 2004 and from our historical audited financial statements for the year ended December 31, 2003. Our historical data was prepared using accounting principles generally accepted in Canada.

      IAMGold’s information has been compiled solely from publicly available information for the same periods as Golden Star’s, as described above. IAMGold has not provided us access to their detailed accounting records nor has IAMGold assisted us in preparing any of the data contained in the pro forma financial statements shown below. IAMGold’s historical data was prepared using accounting principles generally accepted in Canada.

      It is management’s opinion that these pro forma consolidated financial statements include all adjustments necessary for the fair presentation, in all material respects, of the transaction described above in accordance with Canadian generally accepted accounting principles applied on a basis consistent with Golden Star’s accounting policies.

      The pro forma consolidated financial statements are not intended to reflect the results of operations or the financial position of Golden Star which would have actually resulted had the proposed transactions been effected on the dates indicated. Further, the pro forma financial information is not necessarily indicative of the results of operations that may be obtained in the future. The unaudited pro forma consolidated financial statements should be read in conjunction with the historical financial statements and notes thereto of Golden Star and IAMGold, described above.

      The pro forma consolidated financial statements assume that IAMGold will combine with Golden Star, and Wheaton River will not combine with Coeur d’Alene. As a result, IAMGold would be required to pay a $23 million break fee to Wheaton River. It also assumes that all of IAMGold’s shareholders elect the all share option rather than the cash and share option. If all of IAMGold’s shareholders elect the cash and share option, the change in the pro forma balance sheet would be a $55 million decrease in the combined company’s cash and a $21 million decrease in goodwill, offset by a $76 million decrease in share capital. If the contingent payment of Cdn$0.20 is made, the impact on the pro forma financial statements would be substantially offset by the elimination of the break fee payable to Wheaton River. If Wheaton River agrees to combine with Coeur d’Alene, rather than IAMGold paying a $23 million break fee, we would receive a $26 million break fee from Coeur d’Alene. The accounting effect of this event on the pro forma financial statements would be a $49 million increase in the combined entity’s cash and a $49 million reduction in goodwill on the balance sheet of the combined entity both at March 31, 2004 under Canadian GAAP and at December 31, 2003 under US GAAP. This change would not affect net income or earnings per share.

3.	SIGNIFICANT ASSUMPTIONS AND ADJUSTMENTS

      The pro forma consolidated financial statements include the following pro forma assumptions and adjustments:

	(a) The unaudited pro forma consolidated financial statements have been compiled using the significant accounting policies as set out in the audited financial statements of Golden Star for the year ended December 31, 2003.
	(b) The December 31, 2003 and the March 31, 2004 pro forma statements of operations assume that the acquisition occurred on January 1, 2003. The March 31, 2004 balance sheet assumes the acquisition occurred at March 31, 2004.

A-14

---

Table of Contents

	(c) All of IAMGold’s assets and liabilities have been restated where appropriate to reflect estimated fair values using purchase accounting concepts. Estimated mining property and equity investment fair values are based upon discounted cash flow analysis.
	(d) IAMGold’s transaction costs are estimated to be $5 million. Golden Star’s transaction costs and fees, including advisors, legal, accounting, exchange fees, regulatory fees, and IAMGold rationalization costs will total approximately $10 million. It is also assumed that IAMGold will pay a $23 million break fee to Wheaton River. See Section 3 of the Circular, “Background to the Offer — Pre-Offer Agreement with Coeur d’Alene”. Assumes that all of IAMGold’s shareholders elect the all share option rather than the cash and share option, and that in-the-money IAMGold options outstanding as of June 28, 2004 are exercised for cash and the IAMGold shares issued are exchanged for Golden Star shares.
	(e) The excess of the purchase price over the fair value of the net assets is shown as goodwill. The goodwill shown in the pro forma financial statements is based upon a preliminary analysis of the factors involved in determining fair values. The final allocation of the purchase price and the fair values of IAMGold’s assets and liabilities is subject to completion of definitive appraisals which would be carried out following completion of the acquisition.
	(f) No adjustments have been made to reflect expected synergies or cost savings of the proposed transaction.
	(g) Amortization has been adjusted to reflect adjustments of asset basis to fair value.
	(h) The impact of differences between the fair value and the tax value of assets and liabilities has been reflected in the future tax balance and the resulting impact on income tax expense has been reflected on the statements of operations.
	(i) The pro forma information has been compiled using a Golden Star common share price of $5.10 per share, being the average of the closing price on the AMEX for the three days before and after May 27, 2004, the date of announcement of Golden Star’s proposed business combination with IAMGold.
	(j) IAMGold’s 2003 and first quarter 2004 exploration costs have been capitalized as deferred exploration to correspond with Golden Star’s accounting policy.
	(k) During the first quarter of 2004, IAMGold changed its accounting policies with respect to the accounting for Asset Retirement Obligations and share options. Golden Star changed its accounting policies for Asset Retirement Obligations and share options effective January 1, 2003. Therefore, IAMGold’s statement of operations for the year ended December 31, 2003 has been restated to account for these changes in accounting policies using the information disclosed in IAMGold’s audited consolidated financial statements for the year ended December 31, 2003, and the consolidated financial statements for the three months ended March 31, 2004.
	(l) Deferred revenues related to hedge positions closed in past periods were assigned a fair value of nil and therefore the revenue recognized in IAMGold’s statements of operations has been reversed on the Golden Star pro forma statements of operation.
	(m) The gain on marketable securities recognized by IAMGold in comprehensive income is eliminated as a pro forma adjustment since the marketable securities were adjusted to fair value in the acquisition of IAMGold by Golden Star.

INSTRUCTIONS

1.   Use of Letter of Acceptance and Transmittal

	(a)	This Letter of Acceptance and Transmittal (or a manually signed facsimile thereof) together with accompanying certificates representing the Deposited Shares and all other documents required by the terms of the Offer to Purchase and this Letter of Acceptance and Transmittal must be received by the Depositary at any of the offices specified on the back cover page no later than 9:00 p.m., (Toronto time), on July 16, 2004, unless the Offer in respect of the Shares is extended or unless the procedure for guaranteed delivery set out in Instruction 2 below is used.
	(b)	The method used to deliver this Letter of Acceptance and Transmittal and any accompanying certificates representing Shares is at the option and risk of the holder, and delivery will be deemed effective only when such documents are actually received by the Depositary. The Offeror recommends that the necessary documentation be hand delivered to the Depositary at any of its offices specified below, and a receipt obtained; otherwise the use of registered mail with return receipt requested, properly insured, is recommended. Holders of Shares whose Shares are registered in the name of a broker, dealer, bank, trust company or other nominee should contact that nominee for assistance in depositing those Shares.

2.   Procedure for Guaranteed Delivery

      If a holder of Shares wishes to deposit such Shares pursuant to the Offer and certificates for such Shares are not immediately available or the holder cannot deliver the certificates and Letter of Acceptance and Transmittal to the Depositary no later than the Expiry Time, those Shares may nevertheless be deposited under the Offer provided that all of the following conditions are met:

	(a)	such deposit is made only at the principal office of the Depositary in Toronto, Ontario by or through an Eligible Institution;
	(b)	a properly completed and duly executed Notice of Guaranteed Delivery (or a manually signed facsimile) is received by the Depositary at its principal office in Toronto, Ontario at or before the Expiry Time; and
	(c)	the certificate or certificates representing the deposited Shares, in proper form for transfer, together with a properly completed and duly signed Letter of Acceptance and Transmittal (or a manually signed facsimile copy) and other documents required by this Letter of Acceptance and Transmittal, are received at the Toronto office of the Depositary by 5:00 p.m. (Toronto time) on the third trading day on the Toronto Stock Exchange after the Expiry Date.

      The Notice of Guaranteed Delivery may be delivered by hand or transmitted by facsimile or mail to the Depositary at the applicable address set out in the Notice of Guaranteed Delivery and must include a guarantee by an Eligible Institution in the form set out in the Notice of Guaranteed Delivery. Delivery of the Notice of Guaranteed Delivery and this Letter of Acceptance and Transmittal and accompanying Share certificates to any office other than such office of the Depositary does not constitute delivery for purposes of satisfying a guaranteed delivery.

      An “Eligible Institution” means a Canadian Schedule I chartered bank, a major trust company in Canada, a member of the Securities Transfer Agent Medallion Program (STAMP), a member of the Stock Exchange Medallion Program (SEMP), or a member of the New York Stock Exchange, Inc. Medallion Signature Program (MSP).

3.   Signatures

      This Letter of Acceptance and Transmittal must be completed and signed by the registered holder of Deposited Shares accepting the Offer described above or by such holder’s duly authorized representative (in accordance with Instruction 5).

	(a)	If this Letter of Acceptance and Transmittal is signed by the registered owner(s) of the accompanying certificate(s), such signature(s) on this Letter of Acceptance and Transmittal must correspond with the

Table of Contents

		name(s) as registered or as written on the face of such certificate(s) without any change whatsoever, and the certificate(s) need not be endorsed. If such transmitted certificate(s) are owned of record by two or more joint owners, all such owners must sign this Letter of Acceptance and Transmittal.
	(b)	If this Letter of Acceptance and Transmittal is signed by a person other than the registered owner(s) of the accompanying certificate(s), or if a cheque is to be issued to a person other than the registered owner(s):

	(i)	such deposited certificate(s) must be endorsed or accompanied by an appropriate transfer power of attorney duly and properly completed by the registered owner(s); and
	(ii)	the signature(s) on such endorsement or power of attorney must correspond exactly to the name(s) of the registered owner(s) as registered or as appearing on the certificate(s) and must be guaranteed as noted in Instruction 4 below.

4.   Guarantee of Signatures

      If this Letter of Acceptance and Transmittal is signed by a person other than the registered owner(s) of the Deposited Shares, or if Deposited Shares not purchased are to be returned to a person other than such registered owner(s) or sent to an address other than the address of the registered owner(s) as shown on the registers of the Company or if payment is to be issued in the name of a person other than the registered owner(s) of the Deposited Shares, such signature must be guaranteed by an Eligible Institution (except that no guarantee is required if the signature is that of an Eligible Institution).

5.   Fiduciaries, Representatives and Authorizations

      Where this Letter of Acceptance and Transmittal is executed by a person acting as an executor, administrator, trustee or guardian, or on behalf of a corporation, partnership or association or is executed by any other person acting in a representative capacity, such person should so indicate when signing and this Letter of Acceptance and Transmittal must be accompanied by satisfactory evidence of the authority to act. The Offeror or the Depositary, at their discretion, may require additional evidence of authority or additional documentation.

6.   Partial Deposits

      If less than the total number of Shares evidenced by any certificate submitted is to be deposited, fill in the number of Shares to be deposited in the appropriate space on this Letter of Acceptance and Transmittal. In such case, the Depositary will use commercially reasonable efforts to cause new certificate(s) for the number of Shares not deposited to be sent to the registered holder as soon as practicable after the Expiry Time. The total number of Shares evidenced by all certificates delivered will be deemed to have been deposited unless otherwise indicated.

7.   Solicitation

      Identify the dealer or broker, if any, who solicited acceptance of the Offer by completing the appropriate box on this Letter of Acceptance and Transmittal and present a list of beneficial holders, if applicable.

8.   U.S. Shareholders and Substitute Form W-9

      United States federal income tax law generally requires that a U.S. Shareholder who receives cash in exchange for Shares must provide the Depositary with his correct Taxpayer Identification Number (“TIN”), which, in the case of a holder of Shares who is an individual, is generally the individual’s social security number. If the Depositary is not provided with the correct TIN or an adequate basis for an exemption, such holder may be subject to penalties imposed by the Internal Revenue Service and backup withholding in an amount equal to 28% of the gross proceeds of any payment received hereunder. If withholding results in an overpayment of taxes, a refund may be obtained.

      To prevent backup withholding, each U.S. Shareholder must provide his correct TIN by completing the “Substitute Form W-9” set forth in this document, which requires such holder to certify under penalties of perjury, (1) that the TIN provided is correct (or that such holder is awaiting a TIN), (2) that (i) the holder is exempt from

10

---

Table of Contents

      Exempt holders (including, among others, all corporations) are not subject to backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt holder must enter its correct TIN in Part 1 of Substitute Form W-9, write “Exempt” in Part 2 of such form, and sign and date the form. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 (the “W-9 Guidelines”) for additional instructions.

      If Shares are held in more than one name or are not in the name of the actual owner, consult the enclosed W-9 Guidelines for information on which TIN to report.

      If a U.S. Shareholder does not have a TIN, such holder should: (i) consult the enclosed W-9 Guidelines for instructions on applying for a TIN, (ii) write “Applied For” in the space for the TIN in Part 1 of the Substitute Form W-9, and (iii) sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number set forth in this document. In such case, the Depositary may withhold 28% of the gross proceeds of any payment made to such holder prior to the time a properly certified TIN is provided to the Depositary, and if the Depositary is not provided with a TIN within sixty (60) days, such amounts will be paid over to the Internal Revenue Service.

      If the Substitute Form W-9 is not applicable to a U.S. Shareholder because such holder is not a U.S. person for United States federal income tax purposes, such holder will instead need to submit an appropriate and properly completed IRS Form W-8 Certificate of Foreign status, signed under penalty or perjury. Such appropriate IRS Form W-8 may be obtained from the Depositary.

      A U.S. SHAREHOLDER WHO FAILS TO PROPERLY COMPLETE THE SUBSTITUTE FORM W-9 SET FORTH IN THIS LETTER OF ACCEPTANCE AND TRANSMITTAL OR, IF APPLICABLE, THE APPROPRIATE IRS FORM W-8 MAY BE SUBJECT TO BACKUP WITHHOLDING OF 28% OF THE GROSS PROCEEDS OF ANY PAYMENTS MADE TO SUCH HOLDER PURSUANT TO THE OFFERS.

9.   Stock Transfer Taxes

      Except as otherwise provided in this Instruction 9, the Offeror will pay all stock transfer taxes with respect to the transfer and sale of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price is to be made to, or if certificates for Shares not deposited or not accepted for payment are to be registered in the name of, any person other than the registered holder(s), or if deposited certificates for Shares are registered in the name of any person other than the person(s) signing this Letter of Acceptance and Transmittal, the amount of any stock transfer taxes (whether imposed on the registered holder(s) or such other person) payable on account of the transfer to such other person will be deducted from the purchase price of such Shares purchased unless evidence satisfactory to the Offeror, in its sole discretion, of the payment of such taxes, or exemption therefrom, is submitted.

10. Miscellaneous

	(a)	If the space on this Letter of Acceptance and Transmittal is insufficient to list all certificates for Deposited Shares, additional certificate numbers and number of Deposited Shares may be included on a separate signed list affixed to this Letter of Acceptance and Transmittal.
	(b)	If Deposited Shares are registered in different forms (e.g., “John Doe” and “J. Doe”), a separate Letter of Acceptance and Transmittal should be signed for each different registration.
	(c)	No alternative, conditional or contingent deposits will be acceptable and no fractional Shares will be purchased. All depositing holders of Shares by execution of this Letter of Acceptance and Transmittal (or a facsimile hereof) waive any right to receive any notice of the acceptance of Deposited Shares for payment, except as required by applicable law.

Each party to any agreement resulting from the acceptance of the Offer unconditionally and irrevocably attorns to the exclusive jurisdiction of the courts of the Province of Ontario.
	(e)	The Offeror will not pay any fees or commissions to any broker or dealer or any other Person for soliciting deposits of Shares pursuant to the Offer except as otherwise set forth in the Offer to Purchase and Circular (other than to the Dealer Managers, the Soliciting Dealers and the Depositary).
