The Board of Directors of Hummingbird (other than Mr. Malik who did not vote due to his employment as a Managing Director at Lehman Brothers Inc., a financial advisor to Hummingbird), based in part on the unanimous recommendation of the Special Committee of independent members of the Board of Directors, has unanimously approved the arrangement and has determined that the arrangement is fair to Hummingbird's shareholders and in the best interests of Hummingbird. To be effective, the arrangement must be approved by a resolution passed by at least two-thirds of the votes cast at the special meeting.

HUMMINGBIRD LTD. MANAGEMENT INFORMATION CIRCULAR This Circular and accompanying form of proxy are furnished in connection with the solicitation of proxies by and on behalf of the management of Hummingbird Ltd. ("Hummingbird") for use at the Meeting and at any adjournment or postponement thereof and for the purposes set forth in the accompanying Notice of Meeting. A glossary of certain terms used in this Circular can be found on pages 46 to 50 of this Circular. Except where otherwise indicated, the information contained in this Circular is given as of June 23, 2006. NOTICE TO SHAREHOLDERS IN THE UNITED STATES Hummingbird is a corporation existing under the laws of Canada. The solicitation of proxies and the transactions contemplated in this Circular involve securities of a Canadian issuer and are being effected in accordance with Canadian corporate and securities laws. The proxy solicitation rules under the United States Securities Exchange Act of 1934, as amended, are not applicable to Hummingbird or this solicitation and therefore this solicitation is not being effected in accordance with U.S. securities laws. Shareholders should be aware that disclosure requirements under Canadian laws may be different from such requirements under U.S. securities laws. Shareholders should also be aware that other requirements under Canadian laws may differ from requirements under U.S. corporate and securities laws. The enforcement by investors of civil liabilities under U.S. securities laws may be affected adversely by the fact that each of Hummingbird and Acquisition Sub exists under the laws of Canada, that some or all of its respective officers and directors are not residents of the United States and a substantial portion of its respective assets may be located outside the United States. You may not be able to sue a Canadian company or its officers or directors in a Canadian court for violations of U.S. securities laws. It may be difficult to compel a Canadian company and its Affiliates to subject themselves to a judgment by a U.S. court. Certain information concerning tax consequences of the Arrangement for Shareholders who are United States taxpayers is set forth in "Certain Tax Considerations for Shareholders -- Certain Canadian Federal Income Tax Considerations -- Shareholders Not Resident in Canada" and "Certain Tax Considerations for Shareholders -- Certain Material United States Federal Income Tax Considerations". Shareholders should be aware that the transactions contemplated herein may have tax consequences both in Canada and in the United States. Such consequences may not be described fully herein. Shareholders should consult with their legal, tax, financial and accounting advisors. CURRENCY All currency amounts referred to in this Circular are expressed in U.S. dollars, unless otherwise indicated. On June 23, 2006, the exchange rate for one U.S. dollar expressed in Canadian dollars based on the noon spot rate of the Bank of Canada was $1.12. CAUTIONARY STATEMENT WITH RESPECT TO FORWARD LOOKING STATEMENTS This Circular contains forward-looking statements about Hummingbird's objectives, strategies, financial condition, results of operations, cash flows and businesses. These forward-looking statements can be identified by the use of terminology such as: "plan", "expect", "believe", "anticipate", "foresee", "should", "intend", "will", "may", "suspect", "estimate", "outlook", "continue", "project" and similar expressions concerning matters that are not historical facts. These statements are based on certain factors and assumptions including, but not limited to, market trends, competitive activities, market acceptance of new products, expected growth, regulatory requirements, foreign exchange rates, the economic environment and other assumptions, which we believe are reasonable based on currently available information. Forward-looking statements are not guarantees of future performance and involve risks, uncertainties and assumptions, which could cause actual results to differ materially from those anticipated in these forward-looking statements. In addition to other factors and matters contained or incorporated in this Circular, Hummingbird believes the following factors could cause actual results to differ materially from those discussed in the forward-looking statements: failure to satisfy the conditions to complete the Arrangement, including the receipt of the required shareholder, court or regulatory approvals; the occurrence of any event, change or other circumstance that could give rise to the termination of the Arrangement Agreement; and retention of customers, suppliers and personnel being adversely affected by the uncertainty surrounding the Arrangement. In light of these risks, which are inherent in forward-looking statements, readers are cautioned not to place undue reliance on these forward-looking statements. Furthermore, the forward-looking statements contained in this Circular are made as of the date of this Circular. Unless otherwise required by applicable law, Hummingbird does not undertake any obligation to update or to revise any of the included forward-looking statements, whether as a result of new information, future events or otherwise. INFORMATION CONTAINED IN THIS CIRCULAR No person has been authorized to give information or to make any representations in connection with the Arrangement other than those contained or incorporated by reference in this Circular and, if given or made, any such information or representations should not be relied upon in making a decision as to how to vote on the Arrangement Resolution or be considered to have been authorized by Hummingbird. This Circular does not constitute an offer to buy, or a solicitation of an offer to sell, any securities, or the solicitation of a proxy, by any person in any jurisdiction in which such an offer or solicitation is not authorized or in which the person making such an offer or solicitation is not qualified to do so or to any person to whom it is unlawful to make such an offer or solicitation.

THIS CIRCULAR AND THE TRANSACTIONS CONTEMPLATED BY THE ARRANGEMENT AGREEMENT AND THE PLAN OF ARRANGEMENT HAVE NOT BEEN APPROVED OR DISAPPROVED BY ANY SECURITIES REGULATORY AUTHORITY NOR HAS ANY SECURITIES REGULATORY AUTHORITY PASSED UPON THE FAIRNESS OR MERITS OF SUCH TRANSACTIONS OR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE. SUMMARY OF MANAGEMENT INFORMATION CIRCULAR The following is a summary of the contents of this Circular. This summary is provided for convenience only and the information contained in this summary should be read in conjunction with, and is qualified in its entirety by, the more detailed information appearing or referred to elsewhere in this Circular, including the Appendices and documents incorporated by reference herein. Certain capitalized words and terms used in this summary and the Circular are defined in the Glossary of Terms found on pages 46 to 50 of this Circular. Meeting of Shareholders The Meeting will be held on Friday, July 21, 2006, at 10:00 a.m. (Toronto time) at The Hummingbird Centre for the Performing Arts, 1 Front Street East, Toronto, Ontario. At the Meeting, the Shareholders will be asked to consider and, if deemed advisable, to pass the Arrangement Resolution. Shareholders of record at the close of business on June 19, 2006 will be entitled to attend and vote at the Meeting or any adjournment or postponement thereof. The Arrangement If the Arrangement Resolution is passed by the affirmative vote of at least two-thirds of the votes cast by the Shareholders present in person or by proxy and entitled to vote at the Meeting and all of the other conditions to closing of the Arrangement are satisfied or waived, the Arrangement will be implemented by way of a court-approved plan of arrangement under the CBCA. Pursuant to the Arrangement, all of the Common Shares will be transferred by the Shareholders to Acquisition Sub for $26.75 in cash per Common Share. In addition, all Options that are outstanding immediately prior to the Effective Time will be transferred to Hummingbird in exchange for a cash payment from or on behalf of Hummingbird equal to the amount (if any) by which $26.75 exceeds the exercise price payable under such Options (as converted into U.S. dollars pursuant to the Plan of Arrangement). See "The Arrangement -- Arrangement Mechanics". As at the close of business on June 19, 2006, there were issued and outstanding 17,617,449 Common Shares and Options to purchase an aggregate of 1,229,287 Common Shares. Recommendation of the Special Committee The Board established the Special Committee of independent members of the Board to consider the Arrangement. The Special Committee has unanimously determined that the Arrangement is fair to Shareholders and in the best interests of Hummingbird and has unanimously recommended that the Board approve the Arrangement and recommend that Shareholders vote FOR the Arrangement. See "The Arrangement -- Recommendation of the Special Committee". Recommendation of the Board The Board (other than Andrew Malik who did not vote due to his employment as a Managing Director at Lehman Brothers Inc., a financial advisor to Hummingbird) has unanimously determined that the Arrangement is fair to Shareholders and is in the best interests of Hummingbird. Accordingly, the Board has approved the Arrangement Agreement and unanimously recommends that Shareholders vote FOR the Arrangement Resolution. All of the directors and executive officers of Hummingbird have advised Hummingbird that they intend to vote or cause to be voted all Common Shares beneficially held by them in favour of the Arrangement Resolution. Fred Sorkin, Hummingbird's Chairman, and Barry Litwin, Hummingbird's Chief Executive Officer, have agreed with Symphony to vote all Common Shares beneficially owned by them in favour of the Arrangement Resolution. See "The Arrangement -- Recommendation of the Board". Reasons for the Arrangement The Special Committee and the Board considered a number of factors in concluding that the Arrangement is in the best interests of Hummingbird and is fair to Shareholders, including: (a) the consideration to be received by Shareholders for each Common Share under the Arrangement represents a premium of approximately 12.92% and 15.53% over the closing trading price of the Common Shares on the NASDAQ and TSX, respectively, on May 24, 2006, the last trading day on the NASDAQ and TSX prior to the approval of the Arrangement by the Board; (b) Hummingbird has participated in numerous discussions and negotiations with other potentially interested third parties, none of which led to a transaction for various reasons; (c) that the Arrangement consideration is all cash, which provides certainty of value to Shareholders compared to a transaction in which Shareholders would receive all or part of their payment in non-cash consideration; (d) the lack of liquidity in Hummingbird's shares in recent years and the negative impact this has had on Shareholders and on the ability of Hummingbird to engage in strategic transactions; (e) the review by the Board of other strategic alternatives to maximize shareholder value, and the Special Committee's and the Board's belief that the Arrangement was the most favourable alternative available at the time the Arrangement Agreement was entered into; (f) the opinion of Lehman Brothers Inc. (which was rendered to the Board and the Special Committee) and the opinion of Banc of America Securities LLC (which was rendered to the Special Committee), each dated May 24, 2006, as to the fairness, from a financial point of view and as of the date of the opinions, of the consideration to be received by the holders of Common Shares pursuant to the proposed Arrangement. See "The Arrangement -- Opinions of Lehman Brothers Inc. and Banc of America Securities LLC"; (g) Symphony's receipt of signed copies of the debt Commitment Letters, containing only limited, customary conditions; (h) under the Arrangement, all Shareholders are treated the same and no Shareholder receives any collateral benefit; (i) the terms and conditions of the Arrangement Agreement do not prevent an unsolicited third party from making a Superior Proposal or, provided Hummingbird complies with the terms of the Arrangement Agreement (including the payment of the Termination Payment in certain circumstances), preclude the Board from considering and acting on a Superior Proposal; (j) the terms and conditions of the Arrangement Agreement, including Hummingbird's, Parent's, Holdco's and Acquisition Sub's representations, warranties and covenants, and the conditions to their respective obligations are, in the judgment of Hummingbird, after consultation with its legal counsel and Lehman Brothers Inc., reasonable and were the product of extensive negotiations between Hummingbird and such advisors and Symphony and its advisors; (k) the Arrangement Resolution must be passed by at least two-thirds of the votes cast by Shareholders present in person or represented by proxy at the Meeting and entitled to vote, and the fact that if a higher offer is made to Shareholders prior to the Meeting, Shareholders are free to support such a higher offer and vote against the Arrangement Resolution; (l) the Arrangement Resolution must be approved by the Court, which will consider, among other things, the fairness and reasonableness of the Arrangement to Shareholders; and (m) the availability of Dissent Rights. The Special Committee and the Board also considered a number of potential risks relating to the Arrangement, including: (a) the risks to Hummingbird if the Arrangement is not completed, including the costs to Hummingbird in pursuing the Arrangement and the diversion of management attention away from the conduct of Hummingbird's business in the ordinary course; (b) the fact that, following the Arrangement, Hummingbird will no longer exist as an independent public company and Shareholders will forego any future increase in value that might result from future growth and the potential achievement of Hummingbird's long-term plans; (c) the conditions to Parent's obligation to complete the Arrangement and the right of Parent to terminate the Arrangement Agreement under certain limited circumstances; (d) the limitations contained in the Arrangement Agreement on Hummingbird's ability to solicit additional interest from third parties, as well as the fact that if the Arrangement Agreement is terminated under certain circumstances, Hummingbird must pay an $11.7 million Termination Payment to Holdco and that, under certain circumstances, Hummingbird must reimburse Parent, Holdco and Acquisition Sub for certain expenses, as described in "Other Terms of the Arrangement Agreement -- Termination Payment" and "Other Terms of the Arrangement Agreement -- Expense Reimbursement"; and (e) the fact that the Arrangement will be a taxable transaction and, as a result, Shareholders will generally be required to pay taxes on any gains that result from their receipt of the consideration in the Arrangement. In reaching its determination, the Special Committee and the Board also considered and evaluated, among other things: (a) information concerning the business, operations, property, assets, financial condition, operating results and prospects of Hummingbird; (b) current industry, economic and market conditions and trends; and (c) historical market prices and trading information with respect to Common Shares. See "The Arrangement -- Reasons for the Arrangement". Opinions of Lehman Brothers Inc. and Banc of America Securities LLC In connection with the Arrangement, the Board and the Special Committee received the following: o the opinion of Lehman Brothers Inc., dated May 24, 2006, to the Board and the Special Committee, the full text of which is attached as Appendix D, to the effect that, as of the date of the opinion and based on and subject to the assumptions and limitations set forth in the opinion, the consideration to be offered in the proposed transaction set forth in the Arrangement Agreement to the Shareholders is fair, from a financial point of view, to such Shareholders; and o the opinion of Banc of America Securities LLC, dated May 24, 2006, to the Special Committee, the full text of which is attached as Appendix E, as to the fairness, from a financial point of view and as of the date of the opinion, of the consideration to be received by the holders of Common Shares pursuant to the proposed Arrangement. The full text of the written opinions states, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken and are incorporated by reference in their entirety into this Circular. Holders of Common Shares are encouraged to read these opinions carefully in their entirety. The opinions were provided to the Board and the Special Committee in connection with their evaluation of the Arrangement. They do not address any other aspect of the Arrangement and do not constitute a recommendation as to how Shareholders should vote or act with respect to the Arrangement. See "The Arrangement -- Opinions of Lehman Brothers Inc. and Banc of America Securities LLC". Required Shareholder Approval The approval of the Arrangement Resolution will require the affirmative vote of at least two-thirds of the votes cast by Shareholders present in person or represented by proxy at the Meeting and entitled to vote in order for Hummingbird to seek the Final Order and implement the Arrangement on the Effective Date in accordance with the Final Order. See "The Arrangement -- Required Shareholder Approval". Support Agreements Mr. Sorkin, Hummingbird's Chairman, and Mr. Litwin, Hummingbird's Chief Executive Officer, collectively own approximately 12.15% of the outstanding Common Shares as at June 19, 2006 and have entered into support agreements with Parent, Holdco and Acquisition Sub pursuant to which, among other things, they have agreed that they will vote their Common Shares in favour of the Arrangement. See "The Arrangement -- Description of the Arrangement -- Support Agreements". Arrangement Mechanics Pursuant to the Arrangement, the following transactions, among others, will occur in the order set out in the Plan of Arrangement: o Hummingbird will cause Lender Sub to lend an aggregate amount of at least $58 million, plus any additional amount that Parent may reasonably request, to Hummingbird and Acquisition Sub as follows: o the aggregate amount required to be paid by Hummingbird in respect of its acquisition of Options pursuant to the Plan of Arrangement will be lent to Hummingbird; and o the balance will be lent to Acquisition Sub; o all Options that are outstanding immediately prior to the Effective Time shall be deemed to be conditionally vested and will be transferred to Hummingbird in exchange for a cash payment from or on behalf of Hummingbird equal to the amount (if any) by which $26.75 exceeds the exercise price payable under such Options (as converted into U.S. dollars pursuant to the Plan of Arrangement), and the Stock Option Plan shall be terminated; and o each Common Share outstanding at the Effective Time and held by a Shareholder shall be transferred to Acquisition Sub in exchange for $26.75 per Common Share in cash. See "The Arrangement -- Arrangement Mechanics". In order to receive the above cash consideration for the Common Shares, a Shareholder must complete, sign, date and return the enclosed Letter of Transmittal in accordance with the instructions set out therein. Sources of Funds for the Arrangement Under the terms of the Arrangement Agreement, Acquisition Sub will pay an aggregate of approximately $471 million to acquire all of the outstanding Common Shares (assuming no Shareholders exercise their Dissent Rights and no Options are exercised between June 19, 2006 and the Effective Time). Acquisition Sub has obtained commitments, subject to certain conditions, from Wells Fargo Foothill, Inc. and Tennenbaum Capital Partners, LLC to provide an aggregate of $340 million in debt financing to fund a portion of this amount. Pursuant to the Arrangement Agreement, the balance of the funds required by Acquisition Sub to acquire the Common Shares will be funded by way of an equity investment by Symphony (or one of its Affiliates) and a loan from a subsidiary of Hummingbird to Acquisition Sub. See "The Arrangement -- Sources of Funds for the Arrangement". Interests of Senior Management and Others in the Arrangement In considering the recommendations of the Special Committee and the Board with respect to the Arrangement, Shareholders should be aware that certain members of Hummingbird's senior management and Board have certain interests in connection with the Arrangement that may present them with actual or potential conflicts of interest in connection with the Arrangement. The Special Committee and the Board are aware of these interests and considered them along with other matters described in "The Arrangement -- Interests of Senior Management and Others in the Arrangement". Superior Proposals In the Arrangement Agreement, Hummingbird has agreed not to, directly or indirectly, among other things, solicit, initiate, facilitate or encourage (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) any inquiries or proposals regarding an Acquisition Proposal. Nonetheless, the Board is permitted to consider and accept a Superior Proposal under certain conditions. Parent is entitled to a five-business day period within which to exercise a right to match any Superior Proposal that the Board proposes to accept, approve or recommend. If the Board accepts a Superior Proposal, Hummingbird is required to pay to Holdco the Termination Payment as set out in the Arrangement Agreement. See "Other Terms of the Arrangement Agreement -- Covenants of Hummingbird Regarding Non-Solicitation". Conditions to the Arrangement Becoming Effective The implementation of the Arrangement is subject to a number of conditions being satisfied or waived by one or both of Hummingbird and Parent at or before the Effective Time, including: o the accuracy of the representations and warranties of Hummingbird and Parent contained in the Arrangement Agreement; o the performance by Hummingbird and Parent of their covenants under the Arrangement Agreement; o the approval of the Arrangement Resolution at the Meeting in accordance with the CBCA and the Interim Order; o receipt of all Regulatory Approvals; o the absence of any Law that makes the Arrangement illegal or otherwise prevents or prohibits consummation of the Arrangement; o the absence of any pending or overtly threatened proceeding by or before any Governmental Entity seeking to prevent or challenge the consummation of the Arrangement; o no Material Adverse Effect on Hummingbird having occurred; o Dissent Rights shall not have been exercised and remain outstanding at the Effective Time with respect to more than 10% of the outstanding Common Shares in connection with the Arrangement; and o the satisfaction of certain conditions precedent set forth in the Commitment Letters. See "Other Terms of the Arrangement Agreement -- Conditions Precedent to the Arrangement". Court Approval The Arrangement requires approval by the Court under Section 192 of the CBCA. Prior to the mailing of the Circular, Hummingbird obtained the Interim Order, which provides for the calling and holding of the Meeting, the Dissent Rights and other procedural matters. A copy of the Interim Order is attached as Appendix G to this Circular. Subject to the approval of the Arrangement Resolution by at least two-thirds of votes cast by Shareholders at the Meeting, the hearing in respect of the Final Order is currently scheduled to take place on July 25, 2006. At the hearing, the Court will consider, among other things, the fairness and reasonableness of the Arrangement. The Court may approve the Arrangement in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court deems fit. See "Principal Legal Matters -- Court Approval of the Arrangement and Completion of the Arrangement". Regulatory Matters The Arrangement is conditional upon approval under the Competition Act, Investment Canada Act and expiration of the applicable waiting period under the HSR Act. See "Principal Legal Matters -- Regulatory Matters". Closing The Arrangement Agreement provides that the Effective Date is to occur on the earlier of (a) (i) five business days after satisfaction or waiver of the conditions to closing, and (ii) the Outside Date, or (b) on such other date as Hummingbird and Parent may agree. The "Outside Date" is defined as September 15, 2006, subject to postponement for up to 90 days by Hummingbird or Parent if the Regulatory Approvals have not been obtained and have not been denied by a non-appealable decision of a Governmental Entity, and may be extended to such later date as may be agreed to in writing by Hummingbird, Parent, Holdco and Acquisition Sub. The Effective Date is currently expected to occur on or about July 27, 2006. Termination of the Arrangement Agreement Hummingbird and Parent may agree in writing to terminate the Arrangement Agreement and abandon the Arrangement at any time prior to the Effective Time. In addition, either Hummingbird or Parent may terminate the Arrangement Agreement and abandon the Arrangement at any time prior to the Effective Time if certain specified events occur. See "Other Terms of the Arrangement Agreement -- Termination" and "Other Terms of the Arrangement Agreement -- Termination Payment". Termination Payment and Expense Reimbursement The Arrangement Agreement provides that Hummingbird will pay to Holdco the Termination Payment of approximately $11.7 million in certain circumstances, including if the Arrangement Agreement is terminated by Hummingbird in connection with its acceptance of any Superior Proposal. See "Other Terms of the Arrangement Agreement -- Termination Payment". The Arrangement Agreement also provides that, if the Arrangement Agreement is terminated in certain circumstances, Hummingbird will pay Holdco up to $2 million as reimbursement of the charges and expenses incurred by Parent, Holdco and Acquisition Sub in connection with the Arrangement. See "Other Terms of the Arrangement Agreement -- Termination Payment". Dissenting Holders' Rights Registered Shareholders are entitled to exercise Dissent Rights by providing written notice to Hummingbird at or before 5:00 p.m. (Toronto time) on July 19, 2006 (or on the day that is two business days immediately preceding any adjourned or postponed Meeting) in the manner described under the heading "Dissenting Holders' Rights" below. If a Registered Shareholder dissents, and the Arrangement is completed, the Dissenting Holder is entitled to be paid the "fair value" of its Dissenting Common Shares as of the close of business on the day before the day the Arrangement Resolution is adopted. This amount may be the same as, more than or less than the $26.75 in cash per Common Share offered under the Arrangement. Only Registered Shareholders are entitled to dissent. Shareholders should carefully read the section in this Circular entitled "Dissenting Holders' Rights" if they wish to exercise Dissent Rights. Certain Canadian Federal Income Tax Considerations Residents of Canada. Generally, a Resident Shareholder who holds Common Shares as capital property will realize a capital gain (or a capital loss) equal to the amount by which the cash received by such Shareholder, net of any reasonable costs of disposition, exceeds (or is less than) the adjusted cost base to the Shareholder of such Common Shares. Non-Residents of Canada. Generally, a Non-Resident Shareholder whose Common Shares do not constitute "taxable Canadian property" for purposes of the Tax Act will not be subject to tax under the Tax Act on any gain realized on the exchange of such Common Shares for cash under the Arrangement. The foregoing is a brief summary of Canadian federal income tax consequences only. Shareholders should read carefully the information in the Circular under the heading "Certain Tax Considerations for Shareholders -- Certain Canadian Federal Income Tax Considerations", which qualifies the summary set forth above. Shareholders are urged to consult their own tax advisors to determine the particular tax consequences to them of the Arrangement. Certain Material United States Federal Income Tax Considerations U.S. Holders. The Arrangement will be a taxable transaction for United States federal income tax purposes. As a result, a U.S. holder (as defined under the heading "Certain Tax Considerations for Shareholders -- Certain Material United States Federal Income Tax Considerations") of Common Shares will generally recognize gain or loss in an amount equal to the difference between the holder's adjusted tax basis in the Common Shares transferred in the Arrangement and the amount of the cash received in the Arrangement. Provided that Hummingbird is not a passive foreign investment company for U.S. federal income tax purposes, this gain or loss will generally be treated as a capital gain or loss if the U.S. holder held the Common Shares as capital assets and will be long-term if the U.S. holder's holding period for the Common Shares exceeds one year. Non-U.S. Holders. A non-U.S. holder (as defined under the heading "Certain Tax Considerations for Shareholders -- Certain Material United States Federal Income Tax Considerations") of Common Shares will generally not be subject to United States federal income tax as a result of the Arrangement provided that any gain attributable to the Common Shares is not effectively connected with the conduct of a trade or business in the United States by the non-U.S. holder, and in the case of a non-U.S. holder that is an individual, such holder has not been present in the United States for 183 days or more in the taxable year of the Arrangement and certain other conditions are satisfied. Shareholders should read carefully the information in the Circular under the heading "Certain Tax Considerations for Shareholders -- Certain Material United States Federal Income Tax Considerations" below, which qualifies the summary set forth above. Shareholders are urged to consult their own tax advisors to determine the particular tax consequences to them of the Arrangement.

A: You can vote your Common Shares by either attending and voting your Common Shares at the Meeting or, if you cannot attend the Meeting, by having your Common Shares voted by proxy. How you exercise your vote depends on whether you are a Registered or Non-Registered Shareholder: o You are a Registered Shareholder if you have a share certificate registered in your name. o You are a Non-Registered Shareholder if your Common Shares are registered in the name of an Intermediary (for example, a bank, a trustee or investment dealer) or the name of a clearing agency of which the Intermediary is a participant. Voting by attending the Meeting If you are a Registered Shareholder, you are entitled to attend the Meeting and cast your vote in person. If you are a Non-Registered Shareholder, you are entitled to attend the Meeting and cast your vote in person, provided you have submitted a properly executed proxy, inserting your name as proxyholder in the blank space provided and returning it in the envelope provided. When you arrive at the Meeting, advise the registration staff that you are a proxy appointee. If you have received a voting instruction form, please follow the instructions on the form. Voting by Proxy How you vote by proxy depends on whether you are a Registered Shareholder or a Non-Registered Shareholder. 1. Voting by proxy -- Registered Shareholders If you are a Registered Shareholder, you may vote your proxy by paper proxy to be returned by mail or delivery. To vote by mail or delivery, your paper proxy must be completed, signed and returned in accordance with the instructions on the paper proxy. Whichever method you choose, your proxy must be received by the Corporate Secretary of Hummingbird, c/o CIBC Mellon Trust Company, no later than 5:00 p.m. (Toronto time) on July 19, 2006 or, if the Meeting is adjourned or postponed, by 5:00 p.m. (Toronto time) on the business day prior to the date on which the adjourned or postponed Meeting is reconvened or held, as the case may be. 2. Voting by proxy -- Non-Registered Shareholders If you are a Non-Registered Shareholder and you receive materials entitling you to vote through an investment dealer or other Intermediary, complete and return the materials in accordance with the instructions provided to you by the investment dealer or other Intermediary. Q: Who votes my Common Shares? A: Each person named in the proxy to represent Shareholders at the Meeting is a director and/or officer of Hummingbird. If you vote by mail or delivery, you can appoint someone else to represent you at the Meeting; however, you must appoint that person or company by inserting his or her name in the appropriate space on the proxy form, or completing another acceptable paper proxy. The person or company you appoint does not need to be a Shareholder but must attend the Meeting in order for your vote to be cast. Q: How will my Common Shares be voted if I return a proxy? A: By completing and returning a proxy, you are authorizing the person named in the proxy to attend the Meeting and vote your Common Shares on each item of business you are entitled to vote on, according to your instructions. If there are no instructions with respect to your proxy, your Common Shares will be voted FOR the Arrangement Resolution. The person you appoint to vote on your behalf may vote as he or she sees fit on any amendment or variation to any of the matters identified in the Notice of Meeting and any other matters that may properly be brought before the Meeting. As of June 23, 2006, neither the Board nor management of Hummingbird is aware of any variation, amendment or other matter to be presented for a vote at the Meeting. Q: Can I revoke a proxy? A: Yes, if you are a Registered Shareholder and have voted by paper, you may revoke it by delivering a duly executed proxy by paper with a later date or a form of revocation of proxy or other instrument in writing signed by you or by your attorney authorized in writing (or if you are a corporation, by a duly authorized officer or attorney). These instruments can be delivered to the Corporate Secretary of Hummingbird, c/o CIBC Mellon Trust Company, 320 Bay Street, Banking Hall Level, Toronto, Ontario M5H 4A6, up to 5:00 p.m. (Toronto time) on July 20, 2006, or if the Meeting is adjourned or postponed, no later than 5:00 p.m. (Toronto time) on the business day preceding the date on which the adjourned or postponed Meeting is reconvened or held, as the case may be. Alternatively, you may revoke your proxy and vote in person, by delivering a form of revocation of proxy or a signed instrument in writing to the Chairman of the Meeting at the Meeting or any adjournment or postponement thereof. You may also revoke your proxy in any other manner permitted by law. If you are a Non-Registered Shareholder, you should contact your nominee to discuss what procedure to follow. Q: In addition to the approval of Shareholders, are there any other approvals required for the Arrangement? A: Yes, the Arrangement requires the approval of the Ontario Superior Court of Justice (Commercial List) and is also subject to the receipt of certain antitrust, competition and other regulatory approvals in Canada and the United States. See "Principal Legal Matters -- Regulatory Matters". Q: Will the Common Shares continue to be listed on the TSX or NASDAQ after the Arrangement? A: No. The Common Shares will be owned by Acquisition Sub and will be de-listed from the TSX and NASDAQ shortly after the completion of the Arrangement. Q: What if ownership of Common Shares has been transferred after June 19, 2006? A: Only persons on the list of Registered Shareholders prepared by Hummingbird as of June 19, 2006 are entitled to vote at the Meeting. Q: When will the Arrangement be implemented? A: Hummingbird and Symphony will implement the Arrangement when all of the conditions to closing have been satisfied or waived (where permitted), but in any event not earlier than July 27, 2006. Because the Arrangement is subject to a number of conditions, some of which are beyond Hummingbird's and Symphony's control, the exact timing of implementation of the Arrangement cannot be predicted with certainty, although it is currently expected that the closing will occur on or about July 27, 2006. Q: When can I expect to receive consideration for my Common Shares? A: As soon as practicable after the completion of the Arrangement and the receipt by the Depositary from you of a properly completed Letter of Transmittal together with your certificates representing Common Shares and all other required documents, the Depositary will make a payment to you in the amount of your portion of the consideration. If you hold your Common Shares through a broker, trustee, financial institution or other nominee, your broker or other nominee will surrender your Common Shares in exchange for your portion of the consideration. Q: Am I entitled to Dissent Rights? A: Pursuant to the Interim Order, Shareholders have a right to dissent in respect of the Arrangement Resolution. Registered Shareholders who properly exercise their Dissent Rights will be entitled to be paid the fair value of their Common Shares. This amount may be the same as, more than or less than the $26.75 in cash per Common Share offered under the Arrangement. If you wish to dissent, you must provide written notice to Hummingbird at or before 5:00 p.m. (Toronto time) on July 19, 2006 (or on the day which is two business days immediately preceding the date that any adjourned or postponed Meeting is reconvened or held, as the case may be) in the manner described under the heading "Dissenting Holders' Rights". It is important that you strictly comply with this requirement, otherwise your Dissent Right may not be recognized. You must also strictly comply with the other requirements of the dissent procedure. Only Registered Shareholders may exercise Dissent Rights. Q: What are the tax consequences of the Arrangement to me? A: Your receipt of the consideration under the Arrangement in exchange for your Common Shares will be a taxable transaction. For further information on certain tax consequences of the Arrangements, see "Certain Tax Considerations for Shareholders". Your tax consequences will depend on your particular situation. You should consult your own tax advisor for a full understanding of the applicable federal, provincial, state, local, foreign and other tax consequences to you resulting from the Arrangement. Q: Who can I contact if I have questions? A: Shareholders who have additional questions about the Arrangement, including the procedures for voting, should contact Georgeson Shareholder Communications Canada Inc. at 1.866.500.8075. Shareholders who have questions about deciding how to vote should contact their professional advisors. THE ARRANGEMENT Background to the Arrangement Agreement The provisions of the Arrangement Agreement are the result of arm's length negotiations conducted between representatives of Hummingbird and Symphony. The following is a summary of the events leading up to the negotiation of the Arrangement Agreement and the meetings, negotiations, discussions and actions between the parties that preceded the execution and public announcement of the Arrangement Agreement. As set out in the following summary, while Lehman Brothers Inc. was involved in certain discussions and transactions with Hummingbird beginning in April 2004 and May 2005, such discussions and transactions were separate from and unrelated to the Arrangement. Discussions with other Potential Acquirors From April 2004 through to the end of 2005, Hummingbird had discussions with at least eight potential acquirors, including both industry participants and private equity firms, about their interest in acquiring Hummingbird. Some of the potential acquirors contacted Hummingbird directly while others were introduced to Hummingbird. The extent and duration of these discussions varied from preliminary discussions only to a lengthy process involving numerous meetings, due diligence investigations, executed confidentiality agreements and exclusivity letters, and negotiations with respect to a definitive agreement. Set forth below is a brief description of the two discussions in which the parties executed exclusivity letters and engaged in significant discussions and negotiations. In April 2004, Fred E. Sorkin, Chairman and the then Chief Executive Officer of Hummingbird, received a telephone call from the Chief Executive Officer of an industry participant who expressed an interest in acquiring Hummingbird. Lehman Brothers Inc. helped Hummingbird evaluate this particular opportunity and assisted with due diligence. In May 2004, Mr. Sorkin, together with A. Barry Litwin, Chief Executive Officer and the then President of Hummingbird, and Inder P.S. Duggal, Chief Financial Officer of Hummingbird, met twice, once in Chicago and once in New York, with senior management of the potential buyer to discuss a transaction. Discussions continued in July 2004, and on August 12, 2004 the parties entered into a confidentiality agreement. On September 2, 2004, the parties entered into a non-binding exclusivity letter that contemplated a transaction in which a portion of the consideration would consist of stock of the buyer. Throughout September, the parties conducted significant due diligence. The exclusivity period expired on October 3, 2004, without being extended. Shortly thereafter, discussions were terminated. In May 2005, Lehman Brothers Inc. introduced the principals of a private equity firm to Hummingbird. After some initial discussions, the parties entered into a confidentiality agreement on June 9, 2005. The parties also met for two days on June 15 and 16, 2005 at Hummingbird's head office. On July 15, 2005, the parties executed an exclusivity letter. During the three-week period of exclusivity, the parties continued negotiations and the potential acquiror and its advisors conducted due diligence. From late July to mid August 2005, the parties negotiated the terms of a draft definitive acquisition agreement. However, in late August, the potential acquiror suggested a price that was not acceptable to the Board, and shortly thereafter the discussions between the parties were terminated. Strategic Review The Board met in New York on December 14, 2005 and January 17, 2006 for the purpose of discussing strategic alternatives for Hummingbird. The Board considered Hummingbird's strengths and weaknesses as a stand-alone company. It also considered the possibility of acquiring other companies, including the likely prices it would be required to pay and whether the Common Shares would be an acceptable currency for making such acquisitions. The Board also discussed the possibility of selling Hummingbird, and the likely prices that might be received for the Common Shares, especially in light of the prices that had been offered in the two proposed transactions described above and in other recent acquisitions of software companies. At these meetings, the Board did not decide on a specific course of action for Hummingbird, but determined to continue its deliberations on strategic alternatives. However, the Board did conclude that the lack of liquidity in the Common Shares, given the low trading volumes, likely made the Common Shares unattractive as an acquisition currency. The Board also concluded that it would not be in the best interests of Hummingbird to engage in a formal auction process to sell the company, since this could have a negative effect on customer and employee relationships during the process. Description of the Arrangement Symphony's Approach In mid-December, 2005, Bill Chisholm, a Managing Director of Symphony called Mr. Malik to discuss the possibility of Symphony acquiring Hummingbird. On January 16, 2006, Mr. Chisholm met with Messrs. Sorkin and Malik to further discuss a potential acquisition of Hummingbird by Symphony. On January 30, 2006, Mr. Chisholm and J.T. Treadwell, Principal of Symphony, attended a meeting with Messrs. Sorkin, Litwin and Duggal, at which a potential acquisition of Hummingbird by Symphony was discussed and a non-disclosure agreement was executed by Hummingbird and Symphony. On February 6, 2006, Mr. Sorkin met in New York with Romesh Wadhwani, Chief Executive Officer and Managing Director of Symphony, and Mr. Chisholm to further discuss a potential acquisition of Hummingbird by Symphony. On February 12, 2006, the Board met in New York to discuss the possible transaction. It considered the potential pricing being discussed, which was higher than the previous transactions discussed above, and authorized management to enter into an exclusivity arrangement with Symphony. The Board also appointed the Special Committee consisting of Stephen Crane, John McLennan, Jack Langer and Mark Spitzer, each an independent director, and designated Mr. Langer as the chairperson. On February 15, 2006, the parties entered into an exclusivity letter that expired on March 31, 2006. From late February until late May, Symphony and its accountants and legal advisors conducted due diligence. The due diligence included a review of documents as well as numerous meetings with management, department heads and others at Hummingbird. On March 3, 2006, at the annual general meeting of Shareholders, Mr. Langer and Mr. Spitzer retired from the Board and John MacDonald, Hadley Ford and John Wade, each an independent director, were appointed as new members of the Board. On March 22, 2006, Messrs. MacDonald, Ford and Wade were appointed by the Board as members of the Special Committee, and Mr. Crane was designated as Chairman of the Special Committee. On April 3 and 4, 2006, Mr. Sorkin had telephonic meetings with Mr. Wadhwani and Mr. Chisholm to further discuss the transaction. On April 5, 2006, the Board had a telephonic meeting in which Mr. Sorkin reported on his discussions with Mr. Wadhwani. Following those discussions, it was agreed that the exclusivity period would be extended until April 23, 2006. Between April 4, 2006 and May 24, 2006, Mr. Crane had a number of calls and correspondence with Banc of America Securities LLC to discuss the engagement by the Special Committee of, and information to be provided to, Banc of America Securities LLC to evaluate, and render an opinion to the Special Committee with respect to, the consideration to be received by the holders of Common Shares pursuant to the proposed Arrangement. On April 25, 2006, Symphony delivered an initial draft of the Arrangement Agreement. The parties negotiated the Arrangement Agreement until it was signed on May 25, 2006. In connection with the transaction, Hummingbird engaged Lehman Brothers Inc. as its financial advisor, pursuant to the terms of an engagement letter dated as of May 8, 2006. On May 13, 2006, Messrs. Wadhwani and Chisholm participated in a conference call with Messrs. Crane and McLennan, each members of the Special Committee, as well as Messrs. Malik and Sorkin, each members of the Board, to discuss the status of the transaction. During this call, there were negotiations concerning various terms of the transaction, including the price and the break-up fee. On May 20, 2006, Mr. Wadhwani had a telephone call with Mr. Sorkin and then sent an email to Mr. Crane. In the email, he informed Mr. Crane that Symphony had completed all business, accounting and legal due diligence and had arranged for 100% of the financing necessary to close the transaction. The correspondence also set forth Mr. Wadhwani's further views concerning price. On May 22, 2006, the Board and the Special Committee met telephonically with their Canadian and U.S. legal counsel and discussed the status of the transaction as well as correspondence received from Mr. Wadhwani. After a lengthy meeting, Mr. Crane conveyed to Mr. Wadhwani the price expectations of the Special Committee. On May 23, 2006, there was further email correspondence between Mr. Wadhwani and Mr. Crane concerning the price. Approval of the Arrangement Agreement On May 24, 2006, the Board and the Special Committee held a joint meeting at which all of the directors were present. The Special Committee and the Board received a comprehensive briefing from legal counsel on the terms and conditions of the Arrangement Agreement as well as the Commitment Letters that Symphony had obtained in connection with its financing. Counsel responded to a variety of questions from the directors on various aspects of the Arrangement Agreement and the Commitment Letters. Lehman Brothers Inc., Hummingbird's financial advisor, provided its oral opinion to the Board and the Special Committee, which was confirmed by delivery of a written opinion dated May 24, 2006, to the effect that, as of that date, subject to the limitations and assumptions set forth therein, the consideration to be received by Shareholders pursuant to the Arrangement Agreement, being $26.75 in cash per Common Share, was fair, from a financial point of view, to the Shareholders. Banc of America Securities LLC delivered to the Special Committee an oral opinion, which was confirmed by delivery of a written opinion dated May 24, 2006, to the effect that, as of that date and subject to various assumptions and limitations described in its opinion, the consideration to be received by the holders of Common Shares was fair, from a financial point of view, to such holders. The Special Committee then met separately with legal counsel and Banc of America Securities LLC to consider its recommendation to the Board. The Special Committee considered the proposed transaction from a business, financial and legal perspective and the reasons for the Arrangement set forth under "Reasons for the Arrangement". The Special Committee concluded that the Arrangement is substantively and procedurally fair to the Shareholders and that the Arrangement is in the best interests of Hummingbird. The Special Committee unanimously resolved to recommend to the Board that it approve the Arrangement. The Board received the report of the Special Committee and, following discussion, resolved that the Arrangement is fair to the Shareholders and is in the best interests of Hummingbird. It also resolved to approve the Arrangement Agreement and authorized management of Hummingbird to finalize the terms of, execute and deliver the Arrangement Agreement, and further resolved to submit the Arrangement Agreement to the Shareholders for approval. The resolutions of the Board were unanimous, but excluded Mr. Malik who recused himself from voting due to his employment as a Managing Director at Lehman Brothers Inc. Support Agreements Parent, Holdco and Acquisition Sub entered into support agreements with Mr. Sorkin, Hummingbird's Chairman, and Mr. Litwin, Hummingbird's Chief Executive Officer, as of May 25, 2006. As of such date, Mr. Sorkin held 1,217,523 Common Shares, representing approximately 7.0% of the outstanding Common Shares, and Mr. Litwin held 923,107 Common Shares, representing approximately 5.3% of the outstanding Common Shares. Pursuant to each agreement, and subject to the terms and conditions contained in each agreement, each of Mr. Litwin and Mr. Sorkin has agreed, among other things, that until the earlier of the Effective Date and the termination of his agreement, he will: o vote or to cause to be voted his Common Shares in favour of the Plan of Arrangement at the Meeting; o exercise the voting rights attaching to his Common Shares to oppose any proposed action by Hummingbird, its shareholders, any of its subsidiaries or any other Person: (i) in respect of any Acquisition Proposal, (ii) which might reasonably be regarded as being directed towards or likely to prevent or delay the successful completion of the Plan of Arrangement, or (iii) which might reasonably be expected to have a Material Adverse Effect; o subject to the proxy granted pursuant to each agreement, not grant or agree to grant any proxy or other right to vote his Common Shares, or enter into any voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of shareholders or give consents or approval of any kind as to his Common Shares; and o not option, sell, transfer, pledge, encumber, grant a security interest in, hypothecate or otherwise convey his Common Shares, or any right or interest therein (legal or equitable), to any Person or agree to do any of the foregoing. Mr. Sorkin and Mr. Litwin have the right to terminate these agreements if the Arrangement Agreement is terminated in accordance with its terms. Execution and Delivery of the Arrangement Agreement The Arrangement Agreement was executed and delivered by the parties thereto after the close of markets on May 25, 2006. The Arrangement Agreement was announced by way of a press release issued before markets opened on the morning of May 26, 2006. Amendment No. 1 to the Arrangement Agreement An amendment to the Arrangement Agreement was executed and delivered by the parties thereto as of June 19, 2006, a copy of which is attached as Appendix C to this Circular. The reason for the amendment was to allow Shareholders to effect a "safe-income tuck-in transaction" on the terms described under "Holding Company Alternative". This amendment was approved by the Board and the Special Committee on June 19, 2006. Recommendation of the Special Committee The Special Committee has determined that the Arrangement is fair to Shareholders and is in the best interests of Hummingbird. Accordingly, the Special Committee has unanimously recommended that the Board approve the Arrangement and recommend that Shareholders vote FOR the Arrangement Resolution. Recommendation of the Board The Board (other than Mr. Malik who did not vote due to his employment as a Managing Director at Lehman Brothers Inc., a financial advisor to Hummingbird) has unanimously determined that the Arrangement is fair to Shareholders and is in the best interests of Hummingbird. Accordingly, the Board has approved the Arrangement Agreement and unanimously recommends that Shareholders vote FOR the Arrangement Resolution. Reasons for the Arrangement In evaluating and approving the Arrangement and in making its recommendation, the Special Committee and the Board considered a number of factors. In view of the variety of factors considered, each of the Special Committee and the Board did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination as to the fairness of the Arrangement and its recommendation to Shareholders to vote for the Arrangement Resolution. The factors considered by the Special Committee and the Board included: (a) the consideration to be received by Shareholders for each Common Share under the Arrangement represents a premium of approximately 12.92% and 15.53% over the closing trading price of the Common Shares on the NASDAQ and TSX, respectively, on May 24, 2006, the last trading day on the NASDAQ and TSX prior to the approval of the Arrangement by the Board; (b) Hummingbird has participated in numerous discussions and negotiations with other potentially interested third parties, none of which led to a transaction for various reasons; (c) that the Arrangement consideration is all cash, which provides certainty of value to Shareholders compared to a transaction in which Shareholders would receive all or part of their payment in non-cash consideration; (d) the lack of liquidity in Hummingbird's shares in recent years and the negative impact this has had on Shareholders and on the ability of Hummingbird to engage in strategic transactions; (e) the review by the Board of other strategic alternatives to maximize shareholder value, and the Special Committee's and the Board's belief that the Arrangement was the most favourable alternative available at the time the Arrangement Agreement was entered into; (f) the opinion of Lehman Brothers Inc. (which was rendered to the Board and the Special Committee) and the opinion of Banc of America Securities LLC (which was rendered to the Special Committee), each dated May 24, 2006, as to the fairness, from a financial point of view and as of the date of the opinions, of the consideration to be received by the holders of Common Shares pursuant to the proposed Arrangement. See "The Arrangement -- Opinions of Lehman Brothers Inc. and Banc of America Securities LLC"; (g) Symphony's receipt of signed copies of the debt Commitment Letters, containing only limited, customary conditions; (h) under the Arrangement, all Shareholders are treated the same and no Shareholder receives any collateral benefit; (i) the terms and conditions of the Arrangement Agreement do not prevent an unsolicited third party from making a Superior Proposal or, provided Hummingbird complies with the terms of the Arrangement Agreement (including the payment of the Termination Payment in certain circumstances), preclude the Board from considering and acting on a Superior Proposal; (j) the terms and conditions of the Arrangement Agreement, including Hummingbird's, Parent's, Holdco's and Acquisition Sub's representations, warranties and covenants, and the conditions to their respective obligations are, in the judgment of Hummingbird, after consultation with its legal counsel and Lehman Brothers Inc., reasonable and were the product of extensive negotiations between Hummingbird and such advisors and Symphony and its advisors; (k) the Arrangement Resolution must be passed by at least two-thirds of the votes cast by Shareholders present in person or represented by proxy at the Meeting and entitled to vote, and the fact that if a higher offer is made to Shareholders prior to the Meeting, Shareholders are free to support such a higher offer and vote against the Arrangement Resolution; (l) the Arrangement Resolution must be approved by the Court, which will consider, among other things, the fairness and reasonableness of the Arrangement to Shareholders; and (m) the availability of Dissent Rights. The Special Committee and the Board also considered a number of potential risks relating to the Arrangement, including: (a) the risks to Hummingbird if the Arrangement is not completed, including the costs to Hummingbird in pursuing the Arrangement and the diversion of management attention away from the conduct of Hummingbird's business in the ordinary course; (b) the fact that, following the Arrangement, Hummingbird will no longer exist as an independent public company and Shareholders will forego any future increase in value that might result from future growth and the potential achievement of Hummingbird's long-term plans; (c) the conditions to Parent's obligation to complete the Arrangement and the right of Parent to terminate the Arrangement Agreement under certain limited circumstances; (d) the limitations contained in the Arrangement Agreement on Hummingbird's ability to solicit additional interest from third parties, as well as the fact that if the Arrangement Agreement is terminated under certain circumstances, Hummingbird must pay an $11.7 million Termination Payment to Holdco and that, under certain circumstances, Hummingbird must reimburse Parent, Holdco and Acquisition Sub for certain expenses, as described in "Other Terms of the Arrangement Agreement -- Termination Payment" and "Other Terms of the Arrangement Agreement -- Expense Reimbursement"; and (e) the fact that the Arrangement will be a taxable transaction and, as a result, Shareholders will generally be required to pay taxes on any gains that result from their receipt of the consideration in the Arrangement. In reaching its determination, the Special Committee and the Board also considered and evaluated, among other things: (a) information concerning the business, operations, property, assets, financial condition, operating results and prospects of Hummingbird; (b) current industry, economic and market conditions and trends; and (c) historical market prices and trading information with respect to Common Shares. The foregoing discussion of the information and consideration of such factors by the Special Committee and the Board is not intended to be exhaustive but is believed to include all material factors considered by the Special Committee and the Board. In reaching its determination to approve and recommend the Arrangement, the Special Committee and the Board did not assign any relative or specific weights to the foregoing factors which were considered, and individual directors may have given different weights to different factors. The Special Committee was, however, unanimous in its recommendation that the Board approve the Arrangement and the Special Committee and the Board recommend that the Shareholders vote in favour of the Arrangement Resolution. Opinions of Lehman Brothers Inc. and Banc of America Securities LLC Lehman Brothers Inc. Lehman Brothers Inc. was retained pursuant to a letter agreement dated as of May 8, 2006 to act as financial advisor to the Board and the Special Committee and to deliver an opinion as to the fairness to Shareholders (other than Symphony and its Affiliates), from a financial point of view, of the consideration being offered under the Arrangement. At the meetings of the Special Committee and the Board on May 24, 2006, Lehman Brothers Inc. delivered its oral opinion to the Special Committee and the Board (subsequently confirmed in writing) to the effect that, as of the date of its opinion, and based on and subject to the assumptions made, information reviewed, matters considered and limits and other limitations set forth therein, the consideration to be offered in the proposed transaction set forth in the Arrangement Agreement to the Shareholders is fair, from a financial point of view, to such Shareholders. The full text of Lehman Brothers Inc.'s written opinion to the Board and the Special Committee, which states, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, is attached as Appendix D to this Circular and is incorporated by reference in its entirety into this Circular. Holders of Common Shares are encouraged to read the opinion carefully in its entirety. Lehman Brothers Inc. delivered its opinion to the Board and the Special Committee for the benefit and use of the Board and the Special Committee in connection with and for purposes of its evaluation of the consideration to be received by the holders of Common Shares pursuant to the Arrangement. Lehman Brothers Inc.'s opinion does not address any other aspect of the Arrangement and does not constitute a recommendation to any Shareholder as to how to vote or act in connection with the Arrangement. Lehman Brothers Inc. has acted as financial advisor to the Board and the Special Committee in connection with the proposed transaction set forth in the Arrangement Agreement and will receive a fee for its services, a portion of which was payable upon delivery of the Lehman Brothers Inc. opinion and the remainder which is contingent upon the consummation of the proposed transaction set forth in the Arrangement Agreement. In addition, Hummingbird has agreed to reimburse Lehman Brothers Inc. for all reasonable expenses and has agreed to indemnify Lehman Brothers Inc. for certain liabilities that may arise out of its engagement as financial advisor, including the rendering of the Lehman Brothers Inc. opinion. Lehman Brothers Inc. also has performed various investment banking services for Hummingbird in the past and has received customary fees for such services. Mr. Malik, a Managing Director of Lehman Brothers Inc., is a member of the Board and, in accordance with Lehman Brothers' policy, recused himself from voting on the proposed transaction set forth in the Arrangement Agreement to avoid the appearance of any conflict of interest. In the ordinary course of its business, Lehman Brothers Inc. actively trades in the equity securities of Hummingbird for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. Banc of America Securities LLC Hummingbird and the Special Committee retained Banc of America Securities LLC to evaluate, and render an opinion to the Special Committee with respect to, the consideration to be received by the holders of Common Shares pursuant to the proposed Arrangement. Banc of America Securities LLC is an internationally recognized investment banking firm which is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. Hummingbird and the Special Committee selected Banc of America Securities LLC on the basis of Banc of America Securities LLC's experience in transactions similar to the Arrangement and its reputation in the technology industry and investment community. On May 24, 2006, at a joint meeting of the Special Committee and the Board held to evaluate the Arrangement, Banc of America Securities LLC delivered to the Special Committee an oral opinion, which was confirmed by delivery of a written opinion dated May 24, 2006, to the effect that, as of the date of the opinion and based on and subject to various assumptions and limitations stated in its opinion, the consideration to be received by the holders of Common Shares pursuant to the proposed Arrangement was fair, from a financial point of view, to such holders. The full text of Banc of America Securities LLC's written opinion to the Special Committee, which states, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, is attached as Appendix E to this Circular and is incorporated by reference in its entirety into this Circular. Holders of Common Shares are encouraged to read the opinion carefully in its entirety. Banc of America Securities LLC delivered its opinion to the Special Committee for the benefit and use of the Special Committee in connection with and for purposes of its evaluation of the consideration to be received by the holders of Common Shares pursuant to the Arrangement. Banc of America Securities LLC's opinion does not address any other aspect of the Arrangement and does not constitute a recommendation to any Shareholder as to how to vote or act in connection with the Arrangement. The decision to enter into the Arrangement Agreement was solely that of the Special Committee and the Board. As described above, Banc of America Securities LLC's opinion was only one of many factors considered by the Special Committee in evaluating the Arrangement and should not be viewed as determinative of the views of the Special Committee, the Board or the management of Hummingbird with respect to the Arrangement or the consideration to be received pursuant to the Arrangement. Hummingbird agreed to pay Banc of America Securities LLC a customary fee upon the rendering of its opinion. Hummingbird also has agreed to reimburse Banc of America Securities LLC for all reasonable expenses, including reasonable fees and disbursements of Banc of America Securities LLC's counsel, incurred in connection with Banc of America Securities LLC's engagement, and to indemnify Banc of America Securities LLC, any controlling person of Banc of America Securities LLC and each of their respective directors, officers, employees, agents, affiliates and representatives against specified liabilities, including liabilities under applicable securities laws. In the ordinary course of their businesses, Banc of America Securities LLC and its affiliates may actively trade or hold securities of Hummingbird and certain affiliates of Symphony and may actively trade or hold loans of Hummingbird, Symphony and their respective affiliates for their own accounts or for the accounts of customers and, accordingly, Banc of America Securities LLC or its affiliates may at any time hold long or short positions in such securities or loans. Required Shareholder Approval At the Meeting, Shareholders will be asked to consider and, if deemed advisable, to pass the Arrangement Resolution. The approval of the Arrangement Resolution will require the affirmative vote of at least two-thirds of the votes cast by holders of outstanding Common Shares entitled to vote and present in person or represented by proxy at the Meeting. The Arrangement Resolution must be passed by the requisite two-thirds majority in order for Hummingbird to seek the Final Order and implement the Arrangement on the Effective Date in accordance with the Final Order. Notwithstanding the approval by Shareholders of the Arrangement Resolution, Hummingbird reserves the right in certain circumstances to not proceed with the Arrangement in accordance with the terms of the Arrangement Agreement such as circumstances in which conditions to completion of the Arrangement in favour of Hummingbird have not been satisfied or waived or in which the Arrangement Agreement has been terminated in accordance with its terms. See "Other Terms of the Arrangement Agreement -- Termination". Arrangement Mechanics The following description is qualified in its entirety by reference to the full text of the Plan of Arrangement which is attached as Appendix F to this Circular. Upon the Arrangement becoming effective, the following transactions, among others, will occur and will be deemed to occur in the order set out in the Plan of Arrangement: o Hummingbird will cause Lender Sub to lend an aggregate amount of at least $58 million, plus any additional amount that Parent may reasonably request, to Hummingbird and Acquisition Sub as follows: o the aggregate amount required to be paid by Hummingbird in respect of its acquisition of Options pursuant to the Plan of Arrangement will be lent to Hummingbird; and o the balance will be lent to Acquisition Sub; o notwithstanding the terms of the Stock Option Plan, all Options that are outstanding immediately prior to the Effective Time shall be deemed to be conditionally vested and will be transferred to Hummingbird in exchange for a cash payment from or on behalf of Hummingbird equal to the amount (if any) by which $26.75 exceeds the exercise price payable under such Options (as converted into U.S. dollars pursuant to the Plan of Arrangement), and the Stock Option Plan shall be terminated; and o each Common Share outstanding at the Effective Time and held by a Shareholder shall be transferred to Acquisition Sub in exchange for $26.75 per Common Share in cash. Letter of Transmittal If you are a Registered Shareholder, you should have received with this Circular a Letter of Transmittal. If the Arrangement Resolution is passed and the Arrangement is implemented, in order to receive the payment for your Common Shares, Registered Shareholders must complete and sign the Letter of Transmittal enclosed with this Circular and deliver it and the other documents required by it to the Depositary in accordance with the instructions contained in the Letter of Transmittal. You can request additional copies of the Letter of Transmittal by contacting the Depositary. The Letter of Transmittal is also available at the SEDAR website at www.sedar.com. The Letter of Transmittal contains procedural information relating to the Arrangement and should be reviewed carefully. Where a certificate for Common Shares has been destroyed, lost or stolen, the Registered Shareholder of that certificate should immediately contact CIBC Mellon Trust Company at www.cibcmellon.com or P.O. Box 7010, Adelaide Street Postal Station, Toronto, Ontario M5C 2W9. A replacement certificate will be issued upon the Registered Shareholder satisfying the requirements of the Transfer Agent and Hummingbird relating to replacement Common Shares certificate(s). The method of delivery of certificates representing Common Shares and all other required documents is at the option and risk of the person depositing the same. Hummingbird recommends that such documents be delivered by hand to the Depositary and a receipt obtained or, if mailed, that registered mail with return receipt requested be used and that appropriate insurance be obtained. If you are a Non-Registered Shareholder, you should carefully follow the instructions from the broker, investment dealer, bank or other intermediary that holds Common Shares on your behalf in order to submit your Common Shares. Delivery of Consideration It is contemplated that as part of the completion of the Arrangement, at or before the Effective Time Acquisition Sub will deliver payment for the Common Shares to the Depositary (which payment will include the funds loaned to Acquisition Sub by Lender Sub described below under "Sources of Funds for the Arrangement -- Loans from Lender Sub") to be held in escrow for the benefit of Shareholders and Hummingbird will deposit with the Depositary payment for the Options (which payment will consist of the funds loaned to Hummingbird by Lender Sub described below under "Sources of Funds for the Arrangement -- Loans from Lender Sub"). The cash deposited with the Depositary shall be held in an interest-bearing account, and any interest earned on such funds shall be for the account of Acquisition Sub. Under no circumstances will interest accrue or be paid to persons depositing Common Shares on the purchase price for Common Shares purchased by Acquisition Sub, regardless of any delay in making such payment. Upon surrender to the Depositary for cancellation of certificate(s) which immediately prior to the Effective Time represented one or more Common Shares, together with the Letter of Transmittal and such additional documents and instruments duly executed and completed as the Depositary may reasonably require, the Shareholder of such surrendered certificate(s) shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such Shareholder as soon as practicable after the Effective Time, a cheque representing the cash which such Shareholder has the right to receive under the Arrangement, less any amounts withheld pursuant to the Plan of Arrangement, and the certificate so surrendered shall forthwith be cancelled. Until surrendered, each certificate which immediately prior to the Effective Time represented Common Shares shall be deemed after the Effective Time to represent only the right to receive upon such surrender a cash payment in lieu of such certificate, less any amounts withheld pursuant to the Plan of Arrangement. On or as soon as practicable after the Effective Date, the Depositary shall deliver on behalf of Hummingbird to each Optionholder as reflected on Hummingbird's books and records a cheque representing the payment to which such holder is entitled in accordance with the Plan of Arrangement (net of any applicable withholdings), against receipt of such documentation as Parent or Hummingbird may reasonably require acknowledging the transfer and termination of the Options held by such Optionholder. Subject to any applicable escheat laws any payment made by way of cheque by the Depositary on behalf of Acquisition Sub or Hummingbird that has not been deposited or has been returned to the Depositary or that otherwise remains unclaimed, in each case on or before the sixth anniversary of the Effective Date, shall cease to represent a right or claim of any kind or nature and the right of the Shareholder or Optionholder to receive the consideration for Common Shares or Options, as the case may be, pursuant to the Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Amalco for no consideration. Hummingbird, Acquisition Sub, Parent, Amalco and the Depositary will be entitled to deduct and withhold from any consideration otherwise payable to a Shareholder or an Optionholder such amounts as Hummingbird, Acquisition Sub, Parent, Amalco or the Depositary is required or permitted to deduct and withhold with respect to such payment under applicable laws. The Depositary will receive reasonable and customary compensation for its services in connection with the Arrangement, will be reimbursed for certain out of pocket expenses and will be indemnified by Hummingbird against certain liabilities under applicable securities laws and expenses in connection therewith. Interests of Senior Management and Others in the Arrangement In considering the recommendations of the Special Committee and the Board with respect to the Arrangement, Shareholders should be aware that certain members of Hummingbird's senior management and Board have certain interests in connection with the Arrangement that may present them with actual or potential conflicts of interest in connection with the Arrangement. The Special Committee and the Board are aware of these interests and considered them along with other matters described above. The executive officers and directors of Hummingbird beneficially own, directly or indirectly, or exercise control or direction over, in the aggregate, 2,141,630 Common Shares (excluding the Common Shares issuable upon the exercise of the Options), representing approximately 12.16% of the Common Shares outstanding as of the close of business on June 19, 2006. All of the Common Shares held by the executive officers and directors of Hummingbird will be treated in the same fashion under the Arrangement as Common Shares held by any other Shareholder. The executive officers and directors of Hummingbird beneficially own, directly or indirectly, or exercise control or direction over, in the aggregate, 992,500 Options, representing approximately 80.74% of the Options outstanding as of the close of business on June 19, 2006. All of the Options held by the executive officers and directors of Hummingbird will be treated in the same manner under the Arrangement as Options held by every other holder of Options. The aggregate consideration payable to the executive officers and directors of Hummingbird under the Arrangement in respect of their Options is approximately $2.2 million (less applicable withholdings), assuming none of them exercises any Options prior to the Effective Date. Certain executive officers of Hummingbird have written employment agreements with Hummingbird that require Hummingbird to pay 30 months' salary, benefits and bonus (based on the largest bonus in the preceding years) in the event of termination of employment without cause or termination of employment following a change of control of Hummingbird. The officers of Hummingbird are also generally entitled to benefits, rights and payments under Hummingbird's various incentive plans. These benefits arise as normal incidents of employment for the officers of Hummingbird and are not materially altered by the completion of the Arrangement. Mr. Crane, as Chairman of the Special Committee, will be paid a fee for his services as such. Further information with respect to the compensation and the financial holdings and interests of the Hummingbird's executive officers is contained in Hummingbird's Management Information Circular dated February 6, 2006 with respect to the annual meeting of Shareholders held on March 3, 2006, which is incorporated by reference into this Circular. See "Additional Information" below. Mr. Sorkin, Hummingbird's Chairman, and Mr. Litwin, Hummingbird's Chief Executive Officer, collectively own approximately 12.15% of the outstanding Common Shares as at June 19, 2006 and have entered into support agreements with Parent, Holdco and Acquisition Sub pursuant to which, among other things, they have agreed that they will vote their Common Shares in favour of the Arrangement. See "The Arrangement -- Description of the Arrangement -- Support Agreements". Mr. Malik, a member of the Board, is employed as a Managing Director by Lehman Brothers Inc., a financial advisor to Hummingbird. Indemnification and Insurance The Arrangement Agreement provides that Parent will, or will cause Acquisition Sub to, at Parent's option, either (a) maintain in effect without any reduction in scope or coverage for not less than six years from the Effective Date, customary policies of directors' and officers' liability insurance providing protection no less favourable to the protection provided by the policies maintained by Hummingbird in favour of the directors and officers of Hummingbird and each of its subsidiaries which are in effect immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred prior to the Effective Time, or (b) purchase as an extension of Hummingbird's current insurance policies, prepaid non cancellable run-off directors' and officers' liability insurance providing coverage comparable to that contained in Hummingbird's existing policy for six years from the Effective Time with respect to claims arising from or related to facts or events that occurred at or prior to the Effective Time. Parent has also agreed that all rights to indemnification or exculpation existing in favour of the directors or officers of Hummingbird or any subsidiary of Hummingbird as at the date of the Confidentiality Agreement, as such term is defined in the Arrangement Agreement (the "Hummingbird D&O Rights"), as provided in Hummingbird's articles or by-laws or as disclosed in connection with the Arrangement Agreement shall survive the transactions contemplated by the Arrangement Agreement and shall continue in full force and effect for a period of not less than six years from the Effective Time. For a period of six years from the Effective Date, Parent will, or will cause Acquisition Sub or Hummingbird to, perform the obligations of Hummingbird under the Hummingbird D&O Rights. Furthermore, in the event Hummingbird or any of its successors or assigns (a) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (b) transfers all or substantially all of its properties and assets to any person, then, and in such case, proper provision shall be made so that such successors and assigns of Hummingbird or, at Parent's option, Parent, shall assume the indemnity obligations set forth in the Arrangement Agreement. Finally, Parent has agreed that such obligations will survive the Arrangement and will continue in full force and effect in accordance with their terms. Intentions of Hummingbird Directors and Executive Officers All directors and executive officers of Hummingbird, who beneficially own, directly or indirectly, or exercise control or direction over, in the aggregate, 2,141,630 Common Shares as at June 19, 2006, representing approximately 12.16% of the outstanding Common Shares, have indicated that they intend to vote FOR the Arrangement Resolution. Mr. Sorkin, Hummingbird's Chairman, and Mr. Litwin, Hummingbird's Chief Executive Officer, have entered into a support agreement with Parent, Holdco and Acquisition Sub pursuant to which they have agreed that they will vote their Common Shares in favour of the Arrangement. See "The Arrangement -- Description of the Arrangement -- Support Agreements". Sources of Funds for the Arrangement Assuming no Shareholders exercise their Dissent Rights and no Options are exercised between June 19, 2006 and the Effective Time, under the terms of the Arrangement Agreement: o approximately $471 million will be required to fund Acquisition Sub's acquisition of all of the outstanding Common Shares; and o approximately $2.5 million will be required to fund Hummingbird's acquisition of all of the outstanding Options. Loans from Lender Sub Pursuant to the Arrangement Agreement, Hummingbird will cause Lender Sub to lend an aggregate amount of at least $58 million, plus any additional amount that Parent may reasonably request, to Hummingbird and Acquisition Sub as follows: o the aggregate amount required to be paid by Hummingbird in respect of its acquisition of Options pursuant to the Plan of Arrangement will be lent to Hummingbird; and o the balance will be lent to Acquisition Sub. Debt Financing Symphony has obtained the Commitment Letters dated May 24, 2006 from each of Wells Fargo Foothill, Inc. and Tennenbaum Capital Partners, LLC to provide an aggregate of $340 million in debt financing for the Arrangement. These commitments are subject to conditions that Hummingbird believes are customary for commercial lending transactions of this kind and which largely reflect the conditions in Parent's favour to the completion of the Arrangement. These commitments will expire on September 15, 2006 if the Arrangement has not been completed by that date. Equity Financing Pursuant to the Arrangement Agreement, Parent has represented to Hummingbird that the loan from Lender Sub and the debt financing described above will, together with direct or indirect equity investment in Acquisition Sub by Symphony (or one of its affiliates), provide sufficient funds to permit Acquisition Sub to pay for Acquisition Sub's acquisition of all of the outstanding Common Shares pursuant to the Arrangement.

Conduct of Hummingbird's Business In the Arrangement Agreement, Hummingbird agreed that, until the earlier of the Effective Date and the termination of the Arrangement Agreement, Hummingbird will, and will cause each of its subsidiaries to, conduct its business in, and not take any action except in, the ordinary course of business and consistent with past practice, to use its commercially reasonable efforts to preserve, among other things, the assets and goodwill of such entities and not to undertake certain types of restricted activities unless Parent otherwise agrees in writing. Covenants In the Arrangement Agreement each of Hummingbird and Parent agreed to, and to cause its subsidiaries to, perform all obligations required or desirable to be performed by it or any of its subsidiaries under the Arrangement Agreement in order to consummate and make effective, as soon as reasonably practicable, the Arrangement and to co-operate with each other in connection therewith. In furtherance of these covenants, each of Hummingbird and Parent agreed to and where appropriate agreed to cause its subsidiaries to take a number of specific actions relating to the implementation of the Arrangement. In addition, Hummingbird has covenanted that it will use its commercially reasonable efforts to ensure that, immediately prior to the Effective Time, Lender Sub will have at least $58 million, plus any additional amount that Parent may reasonably request, in cash which amount will be lent to Acquisition Sub and Hummingbird as part of the Plan of Arrangement as described under "Sources of Funds for the Arrangement -- Loans from Lender Sub". None of the funds so lent to Acquisition Sub may come from Hummingbird or any of its subsidiaries organized or incorporated under the laws of Canada or any jurisdiction in Canada. Hummingbird has also covenanted that following payment by Hummingbird and Acquisition Sub for the Options and Common Shares acquired under the Arrangement, it will have consolidated cash in an amount that is not less than the sum of: o Hummingbird's then current bona fide estimate of its unpaid fees, costs and expenses in connection with the Arrangement; plus o Hummingbird's then current bona fide estimate of the unpaid amounts payable to the selling shareholders under the acquisition agreement pursuant to which Hummingbird acquired RedDot Solutions AG; plus o a specified amount of cash between $19 million (if the Effective Time occurs on or before July 31, 2006) and $22 million (if the Effective Time occurs after August 31, 2006); plus o if Hummingbird's consolidated accounts payable is greater than $13.5 million, the amount of such difference. Hummingbird also agreed in the Arrangement Agreement to effect such reorganization of its business, operations and assets or such other transactions (each, a "Pre-Acquisition Reorganization") as Parent may reasonably request prior to the Effective Date, and the Plan of Arrangement, if required, shall be modified accordingly; provided, however, that Hummingbird need not effect a Pre-Acquisition Reorganization which, in the opinion of Hummingbird, would prejudice it or Shareholders or would impede or materially delay completion of the Arrangement. Pursuant to the Arrangement Agreement, Parent shall also be entitled, at any time prior to the Meeting, to propose modifications to the Arrangement to: (a) increase the consideration it or Acquisition Sub is prepared to make available to Shareholders pursuant to the Arrangement, whether or not the Board has changed its recommendation, provided that Parent shall use its commercially reasonable efforts to provide not less than one business day's prior written notice of such proposal to Hummingbird; or (b) modify the terms of the Arrangement to achieve tax planning objectives of Parent, Holdco and Acquisition Sub, including to provide for one or more amalgamations of subsidiaries of Parent, Holdco and/or Hummingbird, which, in the opinion of Hummingbird, acting reasonably, (i) would not prejudice it or Shareholders, or (ii) would not impede or materially delay the completion of the transactions contemplated by the Arrangement Agreement provided that Parent, Holdco or Acquisition Sub has provided notice of such modification to Hummingbird not less than 15 business days prior to the Meeting date. Covenants of Hummingbird Regarding Non-Solicitation The Arrangement Agreement contains certain "non-solicitation" provisions pursuant to which Hummingbird has agreed that it will not, directly or indirectly, through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries: o solicit, initiate, facilitate or encourage (including by way of furnishing information or entering into any form of agreement, arrangement or understanding, but excluding compliance by Hummingbird with its continuous reporting obligations under applicable securities Laws in the ordinary course consistent with past practice) any inquiries or proposals regarding, constituting or that would reasonably be expected to lead to, an Acquisition Proposal; o participate in any discussions or negotiations regarding an Acquisition Proposal; o withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Parent, the approval of the Board of the Plan of Arrangement; o approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal; or o accept or enter into, or propose publicly to accept or enter into, any agreement, understanding or arrangement in respect of an Acquisition Proposal. The Arrangement Agreement provides that, notwithstanding the foregoing restrictions, the Board is not prevented from taking any of the actions described above in respect of an unsolicited bona fide written Acquisition Proposal received after the date of the Arrangement Agreement that: o did not result from a breach of any agreement between the person making such Acquisition Proposal and Hummingbird or any of its subsidiaries, or the provisions of the Arrangement Agreement governing Hummingbird's non-solicitation covenants; o involves not less than 66 (2)/3 percent of the outstanding Common Shares or not less than 66 (2)/3 percent of the consolidated assets (measured on a fair value) of Hummingbird; and o in respect of which the Board determines in its good faith judgment pursuant to the exercise of its fiduciary duties under applicable Laws, after consultation with its financial advisors and its outside counsel, that there is a substantial likelihood that any required financing will be obtained and that the Acquisition Proposal would, if consummated in accordance with its terms (but not assuming away any risk of non-completion), result in a transaction that: (i) is reasonably capable of completion in accordance with its terms without significant additional delay, taking into account all legal, financial, regulatory, financing and other aspects of such Acquisition Proposal and the person making such Acquisition Proposal; and (ii) is more favourable from a financial point of view to Shareholders than under the Plan of Arrangement on a cash-equivalent basis taking into account any approval requirements and all other financial, legal, regulatory and other aspects of such proposal (including any proposal made by Parent or Acquisition Sub in response to such Acquisition Proposal or otherwise), any such Acquisition Proposal being referred to in the Arrangement Agreement as a "Superior Proposal". Hummingbird was also required, as of the date of the Arrangement Agreement, to immediately terminate any existing discussions or negotiations with any parties (other than Parent) with respect to any proposal that constitutes, or may reasonably be expected to constitute, an Acquisition Proposal. Hummingbird has agreed not to release any third party from (a) any confidentiality agreement or (b) any standstill agreement or provision in each case to which such third party is a party unless such third party has made a Superior Proposal and Hummingbird has accepted such Superior Proposal. If Hummingbird receives a request for material non-public information from a Person who proposes an unsolicited bona fide Acquisition Proposal, Hummingbird may request clarifications in writing from such Person solely for purposes of valuing, and solely in respect of, any non-cash consideration that is offered under such Acquisition Proposal, provided that such clarifications are reasonably necessary as part of the efforts of the Board to ascertain whether such Acquisition Proposal is, or is reasonably likely to be, if consummated in accordance with its terms, a Superior Proposal. If Hummingbird receives a request for material non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal and the Board of Directors of Hummingbird determines that such proposal would reasonably likely be, if consummated in accordance with its terms, a Superior Proposal, then, and only in such case, the Board of Directors of Hummingbird may, subject to the execution by such person of a confidentiality agreement having substantially the same terms as the Confidentiality Agreement, provide such person with access in accordance with the requirements set forth above to such information regarding Hummingbird, acting reasonably, provided however that the person making the Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal, and provided further that Hummingbird sends immediately a copy of any such confidentiality agreement to Parent upon its execution and Parent is immediately provided with a list and copies of all information provided to such person not previously provided to Parent and is immediately provided with access to information similar to that which was provided to such person. Hummingbird has agreed to immediately notify Parent of, at first orally and then, within 24 hours, in writing, any Acquisition Proposal or inquiry that would reasonably be expected to lead to an Acquisition Proposal, of which any of its directors or officers become aware, or any amendments to the foregoing, or any request for non-public information relating to Hummingbird or any of its subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records of Hummingbird or any of its subsidiaries by any person that informs Hummingbird or such subsidiary that it is considering making, or has made, an Acquisition Proposal and any amendment thereto. Hummingbird has agreed to keep Parent promptly and reasonably informed from time to time of the status, including any change to the material terms of any such Acquisition Proposal or inquiry. Such notice shall include or be accompanied by a copy of all documentation relating to any Acquisition Proposal and any amendment thereto and a description of all material terms of any oral or other communications related to any Acquisition Proposal, including the identity of the person making such Acquisition Proposal and such other details as Parent may reasonably request. Hummingbird has agreed that it shall ensure that its officers and directors and those of its subsidiaries and any financial or other advisors, agents or representatives retained by it are aware of the non-solicitation provisions of the Arrangement Agreement, and Hummingbird shall be responsible for any breach of such provisions by any such Person or its advisors or representatives. Acceptance of a Superior Proposal Hummingbird is not permitted to accept, approve or recommend, nor enter into any agreement relating to, a Superior Proposal (other than a confidentiality agreement contemplated by the Arrangement Agreement) unless: o Hummingbird has complied fully with the non-solicitation restrictions in the Arrangement Agreement described above; o a period of five business days shall have elapsed from the date on which Parent received both a copy of the Superior Proposal together with written notice from the Board that the Board determined, subject only to compliance with the Arrangement Agreement, to accept, approve, recommend or enter into a binding agreement to proceed with the Superior Proposal; o it provides Parent with an opportunity (within five business days) to propose to amend the terms of the Arrangement, as described below; and o it pays to Parent the Termination Payment as described below under "-- Termination Payment". Right to Match During the five-business day period referred to above, Parent shall have the right, but not the obligation, to offer to amend the terms of the Transactions. The Board will review any such proposal by Parent to amend the terms of the Transactions, including an increase in, or modification of, the consideration to be received by the holders of Common Shares, to determine whether the Acquisition Proposal to which Parent is responding would be a Superior Proposal when assessed against the Transactions as it is proposed by Parent to be amended. If the Board does not so determine, the Board will promptly reaffirm its recommendation of the Transactions as amended and Hummingbird will not implement the proposed Superior Proposal. Termination Hummingbird and Parent may agree in writing to terminate the Arrangement Agreement and abandon the Arrangement at any time prior to the Effective Date, even after Shareholders have passed the Arrangement Resolution at the Meeting. The Arrangement Agreement may also be terminated and the Arrangement may be abandoned at any time prior to the Effective Time: (a) by Parent if there shall have occurred up to and including the Effective Date, a Material Adverse Effect in respect of Hummingbird; (b) by Parent or by Hummingbird, if any Law makes the completion of the Transactions illegal or otherwise prohibited; (c) subject to applicable cure periods, by Parent, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of Hummingbird set forth in the Arrangement Agreement or any such representation and warranty shall have become untrue after the date of the Agreement, such that the closing conditions in Parent's favour relating to the accuracy of Hummingbird's representations and warranties or the performance by Hummingbird of its covenants would not be satisfied; (d) subject to applicable cure periods, by Hummingbird, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of Parent set forth in the Arrangement Agreement or any such representation and warranty shall have become untrue after the date of the Arrangement Agreement, such that the closing conditions in Hummingbird's favour relating to the accuracy of Parent's representations and warranties or the performance by Hummingbird of its covenants would not be satisfied; (e) by Parent, if the Board shall have: (i) withdrawn, withheld, qualified or modified in a manner adverse to Parent its recommendation of the Arrangement Agreement (it being understood that the taking of a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification), (ii) after being requested by Parent in writing, failed to reaffirm its recommendation of the Arrangement as promptly as practicable (but in any event within two business days) after receipt of any written request to do so from Parent or (iii) approved or recommended an Acquisition Proposal or entered into a binding written agreement in respect of an Acquisition Proposal (other than a confidentiality agreement permitted by the Arrangement Agreement); (f) by Hummingbird, in order to enter into a binding written agreement with respect to a Superior Proposal (subject to certain exceptions), subject to compliance with the non-solicitation and right to match provisions of the Arrangement Agreement and provided that no such termination shall be effective unless and until Hummingbird shall have paid the Termination Payment to Parent; (g) by Parent or by Hummingbird, if the Effective Time shall not have occurred on or before the Outside Date; provided, that such right to terminate shall not be available to any party that has breached in any material respect its obligations under the Arrangement Agreement in any manner that shall have proximately contributed to the occurrence of the failure of the Effective Time to occur on or before such date; or (h) by Parent, if the Arrangement Resolution shall have failed to receive the requisite approval of at least two-thirds of the votes cast at the Meeting or at any adjournment or postponement thereof in accordance with the CBCA. Termination Payment Hummingbird must make a Termination Payment of $11,714,586 (less any amounts paid in accordance with the provisions described under "-- Expense Reimbursement" below) to Holdco, if: o the Arrangement Agreement is terminated in the circumstances set out in paragraphs (e) or (f) under "-- Termination" above; o (A) the Arrangement Agreement is terminated in the circumstances set out in: (1) paragraphs (g) or (h) under "-- Termination" above and the Arrangement has failed to receive the requisite approval of the Shareholders in accordance with applicable Law; or (2) paragraph (c) under "-- Termination" above, provided that in the case of a breach of a representation or warranty such breach was made knowingly by Hummingbird; (B) an Acquisition Proposal has been negotiated or discussed with Hummingbird (directly or indirectly through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries), made or publicly announced or an inquiry to Hummingbird (directly or indirectly through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries) concerning an Acquisition Proposal has been made, in each case prior to the termination of the Arrangement Agreement; and (C)(1) an agreement or a letter of intent in respect of any Acquisition Proposal has been entered into by Hummingbird on or before the first anniversary of the termination of this Agreement and such Acquisition Proposal has been completed; or (2) any Acquisition Proposal, in respect of which Hummingbird has not entered into an agreement or a letter of intent, has been completed on or before the first anniversary of the termination of this Agreement; or o Hummingbird has breached its obligations under non-solicitation and right to match provisions of the Arrangement Agreement. Expense Reimbursement Hummingbird must reimburse Holdco within 5 days following Holdco's request for all of the charges and expenses incurred by Parent, Holdco and Acquisition Sub in connection with the Arrangement Agreement, the Transactions and the financing thereof if the Arrangement Agreement is terminated: o in the circumstances set out in paragraphs (a) or (c) under "-- Termination" above; or o in the circumstances set out in paragraphs (g) or (h) under "-- Termination" above and the Arrangement has failed to receive the requisite approval of the Shareholders in accordance with applicable Law. The maximum amount that Hummingbird will be required to pay to Holdco as expense reimbursement will be $2 million (which maximum amount will be reduced to $1 million if the Arrangement Agreement has been terminated in the circumstances set out in paragraph (h) under "Termination" above where the Shareholders have voted on the Arrangement Resolution at the Meeting but the Arrangement Resolution failed to receive the requisite approval of at least two-thirds of the votes cast at the Meeting). No expense reimbursement will be payable in circumstances where the Holdco has already received a Termination Payment. HOLDING COMPANY ALTERNATIVE If you hold Common Shares directly or indirectly through one or more federal Canadian holding companies incorporated after June 19, 2006, you will have the option of completing a corporate reorganization with Hummingbird after the Meeting but prior to the Effective Time of the Arrangement. Under this "holding company alternative," Hummingbird will purchase all of the issued and outstanding shares of your Canadian holding company in exchange for the issuance by Hummingbird of the same number of Common Shares as are held by your holding company at the time of the purchase and sale. If you participate in the holding company alternative, you will receive, directly or indirectly, the same consideration under the Arrangement that you would otherwise have received. Your holding company will become a wholly-owned subsidiary of Hummingbird under the holding company alternative. Hummingbird has agreed to commence the voluntary liquidation or dissolution of all those holding companies under the CBCA and to cancel all the Common Shares held by such holding companies prior to the Effective Time of the Arrangement. Choosing the holding company alternative will require you to implement a complex corporate structure through which to hold Common Shares. The holding company alternative may have favourable Canadian federal income tax consequences for you that are not described in this document. If you wish to avail yourself of the holding company alternative, you should consult your own financial, tax and legal advisors. You will be permitted to participate in the holding company alternative provided that all of the following terms and conditions are satisfied: o you advise Hummingbird c/o Hummingbird's Corporate Secretary at 1 Sparks Avenue, Toronto, Ontario M2H 2W1, not later than 5:00 p.m. (Toronto time) on July 13, 2006, in writing, that you wish to participate in the holding company alternative; o you hold or will hold Common Shares indirectly through a holding company that was incorporated under the CBCA after June 19, 2006 and was used solely in relation to the holding company alternative, has at all times since its incorporation been validly in existence and in good standing under the CBCA, and is a resident of Canada and a "taxable Canadian corporation" for the purposes of the Tax Act; o you and your holding company enter into a holding company participation agreement, as described below, with, among others, Hummingbird, substantially in the form of agreement attached as Appendix D to the Arrangement Agreement, as amended; o you provide Hummingbird and Parent with security satisfactory to Hummingbird and Parent in respect of your obligations under the holding company participation agreement; o your holding company does not declare or pay dividends (except as agreed to by Hummingbird and Parent) or effect other distributions or redemptions, except that in the event that the holding company receives a dividend from Hummingbird, the holding company will declare and pay a dividend and/or redeem shares in the same amount and form immediately following the receipt of the dividend by the holding company and prior to the completion of the holding company alternative; o the holding company participation agreement, together with any accompanying required documentation is completed, executed and returned to Hummingbird's Corporate Secretary at 1 Sparks Avenue, Toronto, Ontario M2H 2W1 not later than 5:00 p.m. (Toronto time) on July 20, 2006 or, if the Meeting is adjourned or postponed, on the day which is five business days immediately preceding the Effective Date; o if you are not a resident of Canada within the meaning of the Tax Act, you provide to Hummingbird, at the time the holding company alternative is completed, a certificate under section 116 of the Tax Act and any equivalent provision of provincial legislation, in form and substance satisfactory to Hummingbird and Parent, acting reasonably, or you enter into arrangements satisfactory to Hummingbird and Parent, acting reasonably, if a section 116 certificate (or any equivalent provincial certificate) is not available at that time; o any exemptions requested from any applicable Canadian securities regulatory authority and the court in the interim order are obtained; and o all other terms and conditions of the holding company alternative are satisfactory to Hummingbird and Parent, acting reasonably. Hummingbird will be applying for orders from the applicable Canadian securities regulatory authorities exempting Hummingbird from the issuer bid requirements of the Canadian provincial securities legislation in connection with the holding company alternative. You must prepare, at your expense, all tax returns of the holding company in respect of all periods ending on or prior to the completion of the holding company alternative, and must not file the returns without the prior approval of Hummingbird and Parent of all the returns as to form and substance. You must also deliver to Hummingbird and Parent no later than July 13, 2006 all draft documentation relating to your proposed holding company alternative, and all reasonable comments of Hummingbird and Parent shall be reflected in the final documentation executed in respect of the holding company alternative. The form of the holding company participation agreement referred to above provides for the purchase by Hummingbird of all of the holding company's issued and outstanding shares in exchange for the issuance by Hummingbird of the same number of Common Shares as are held by the holding company at the time of the purchase and sale. This agreement contains representations and warranties, covenants and conditions that are customary for transactions of this nature, including representations and warranties that you must make in respect of your holding company to the effect that: o the holding company is a corporation duly incorporated subsequent to June 19, 2006 and validly existing and in good standing under the CBCA; o all of the issued and outstanding shares of the holding company are held directly or indirectly by you; o upon completion of the holding company alternative, Hummingbird will acquire the sole legal and beneficial ownership of all of the issued and outstanding shares of the holding company; o the holding company has no material assets other than the Common Shares and has no liabilities whatsoever; o since incorporation, the sole activities of the holding company have been the acquisition and ownership of the Common Shares and other matters expressly contemplated by the holding company participation agreement; o the holding company is not a party to nor bound or affected by any agreements, commitments or undertakings of any nature whatsoever other than the holding company participation agreement and except as agreed to by Hummingbird and Parent; o in respect of tax matters, the holding company: o has duly and timely paid all taxes which are or have been due and payable by it; o has duly and timely filed with the appropriate taxing or other governmental authority all tax returns required to be filed by it; o is a "taxable Canadian corporation" for purposes of the Tax Act; and o there are no suits, actions, litigation, or other proceedings in progress, pending or threatened against or relating to the holding company. The form of holding company participation agreement also provides for: o the payment by you of all costs and expenses incurred by any of Hummingbird, Parent, Holdco, Acquisition Sub or the holding company in connection with any transaction entered into under the holding company participation agreement; o an indemnity in favour of Hummingbird, Parent, Holdco, Acquisition Sub and the holding company (and their respective directors and officers, employees, advisors and agents) from all actions, claims, demands, processes, proceedings, losses, damages, liabilities, deficiencies, taxes, costs and expenses suffered or incurred by Hummingbird, Parent, Holdco, Acquisition Sub and the holding company (and their respective directors and officers, employees, advisors and agents), in connection with the holding company alternative as a result of: o any breach by you or the vendors of any representation, warranty, obligation or covenant of you or the vendors to Hummingbird; o any liability sustained, incurred, assumed or acquired by the holding company on or before the completion of the holding company alternative; or o the holding company participation agreement and the transactions contemplated thereby, including the winding-up of the holding company into Hummingbird prior to the Effective Time; and o a release of Hummingbird, Parent, Holdco, Acquisition Sub (and their respective successors, assigns, parent companies, subsidiaries, affiliated companies, and all of the present and former directors, officers, employees, advisors and agents of these entities) from all liabilities suffered or incurred as a result of or with respect to or in any way connected with the transactions contemplated by the holding company participation agreement. PRINCIPAL LEGAL MATTERS Court Approval of the Arrangement and Completion of the Arrangement An arrangement under the CBCA requires Court approval. Prior to the mailing of this Circular, Hummingbird obtained the Interim Order, which provides for the calling and holding of the Meeting, the Dissent Rights and other procedural matters. A copy of the Interim Order is attached as Appendix G to this Circular. Subject to approval of the Arrangement Resolution by Shareholders at the Meeting, the hearing in respect of the Final Order is currently scheduled to take place on July 25, 2006 at 10:00 a.m. (Toronto time) in the Court at 393 University Avenue, Toronto, Ontario. Any Shareholder or other person who wishes to appear, or to be represented, and to present evidence or arguments must serve and file a notice of appearance (a "Notice of Appearance") as set out in the Notice of Application for the Final Order and satisfy any other requirements of the Court. The Court will consider, among other things, the fairness and reasonableness of the Arrangement. The Court may approve the Arrangement in any manner the Court may direct, subject to compliance with any terms and conditions, if any, as the Court deems fit. In the event that the hearing is postponed, adjourned or rescheduled then, subject to further order of the Court, only those persons having previously served a Notice of Appearance in compliance with the Notice of Application and the Interim Order will be given notice of the postponement, adjournment or rescheduled date. A copy of the Notice of Application for the Final Order is attached as Appendix H to this Circular. Assuming the Final Order is granted and the other conditions to closing contained in the Arrangement Agreement are satisfied or waived to the extent legally permissible, then Articles of Arrangement will be filed with the Director to give effect to the Arrangement. Regulatory Matters The Arrangement is conditional upon the receipt of all approvals under the Competition Act (Canada), the HSR Act and the Investment Canada Act (Canada) (described below). Competition Act The Competition Act (Canada) requires that parties to certain merger transactions that exceed specified size thresholds provide to the Commissioner of Competition (the "Commissioner") appointed under the Competition Act prior notice of, and information relating to, the merger transaction. Notification must be made either on the basis of a short-form filing (in respect of which there is a 14-day statutory waiting period from the time a complete notification is made) or a long-form filing (in respect of which there is a 42-day waiting period from the time a complete notification is made). As an alternative to filing a notification, parties may request an advance ruling certificate, which if issued, exempts the proposed transaction from notification. Under section 113(c) of the Competition Act, the Commissioner may also waive the obligation to notify where substantially similar information was previously provided pursuant to a request for an advance ruling certificate. The Commissioner's review of a proposed transaction may take longer than the statutory waiting period. Upon completion of the Commissioner's review, the Commissioner may decide to (i) challenge the proposed transaction, if the Commissioner concludes that it is likely to substantially lessen or prevent competition, (ii) issue a "no action" letter stating that the Commissioner does not intend to challenge the proposed transaction at that time but retains the authority to do so for three years after completion of the proposed transaction, or (iii) issue an advance ruling certificate. Where an advance ruling certificate is issued and the proposed transaction to which the advance ruling certificate relates is substantially completed within one year after the advance ruling certificate is issued, the Commissioner cannot seek an order of the Competition Tribunal in respect of the proposed transaction solely on the basis of information that is the same or substantially the same as the information on the basis on which the advance ruling certificate was issued. On June 23, 2006 Symphony and Hummingbird requested that the Commissioner issue an advance ruling certificate in respect of this proposed transaction or in the alternative that the Commissioner waive the obligation to notify and issue a "no action" letter. HSR Act Under the HSR Act, certain acquisition or merger transactions may not be consummated until a Pre-Merger Notification and Report Form is filed (an "HSR Filing") with the Antitrust Division of the United States Department of Justice (the "Antitrust Division") and the United States Federal Trade Commission (the "FTC") and the applicable waiting period has expired or been terminated. On June 1, 2006, Hummingbird made an HSR Filing in connection with the Arrangement. On June 5, 2006, Symphony made an HSR Filing in connection with the Arrangement. On June 21, 2006, the Antitrust Division and the FTC granted early termination of the waiting period. Under the HSR Act and applicable regulations, no additional HSR Filing is required in connection with the Arrangement provided that the Arrangement is consummated on or before July 5, 2007. In addition to the authority vested in the FTC and Antitrust Division under the HSR Act, the U.S. government may scrutinize the legality under federal antitrust law of transactions such as the proposed acquisition of Common Shares by Symphony pursuant to the Arrangement. At any time before or after the purchase by Symphony of Common Shares pursuant to the Arrangement, the FTC or the Antitrust Division may take such action under United States antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the purchase of Common Shares pursuant to the Arrangement or seeking the divestiture of Common Shares purchased by Symphony or the divestiture of substantial assets of Symphony, its subsidiaries or Hummingbird. Private parties (including individual States) also may seek to take legal action under United States and/or state antitrust laws under certain circumstances. Based upon an examination of publicly available information and the results of its due diligence of the businesses in which Hummingbird and its subsidiaries are engaged, Symphony believes that the Arrangement will not violate U.S. antitrust laws. Nevertheless, there can be no assurance that a challenge to the Arrangement will not be made or, if such a challenge is made, that the outcome will be favourable to Hummingbird or Symphony. Investment Canada Act Under the Investment Canada Act, certain transactions involving the acquisition of control of a Canadian business by a non-Canadian that exceed prescribed monetary thresholds are subject to review and cannot be implemented unless the applicable Minister responsible for the Investment Canada Act is satisfied that the acquisition is likely to be of net benefit to Canada. The Minister of Canadian Heritage (for cultural activities) and the Minister of Industry (for all other activities) are the two Ministers that are responsible for reviewing transactions. Where a transaction is subject to the review requirement (a "Reviewable Transaction"), an application for review must be filed with the applicable Director of Investments appointed by the responsible Minister prior to the implementation of the Reviewable Transaction. The responsible Minister is then required to determine whether the Reviewable Transaction is likely to be of net benefit to Canada. The prescribed factors of assessment to be considered by the responsible Minister include, among other things, the effect of the investment on the level and nature of economic activity in Canada (including the effect on employment, resource processing, utilization of Canadian products and services and exports), the degree and significance of participation by Canadians in the acquired business, the effect of the investment on productivity, industrial efficiency, technological development, product innovation and product variety in Canada, the effect of the investment on competition within any industry in Canada, the compatibility of the investment with national industrial, economic and cultural policies (taking into consideration corresponding provincial policies) and the contribution of the investment to Canada's ability to compete in world markets. The Investment Canada Act contemplates a review period of 45 days after filing; however, if the responsible Minister has not completed the review by that date, the responsible Minister may unilaterally extend the review period by up to 30 days (or such longer period as the Minister and the applicant may agree) to permit completion of the review. In determining whether a Reviewable Transaction is of net benefit to Canada, the responsible Minister can take into account, among other things, the previously noted factors specified in the Investment Canada Act, as well as any written undertakings that may be given by the applicant. If a notice that a Reviewable Transaction is determined not to be of net benefit to Canada is sent to the applicant, the Reviewable Transaction may not be implemented (although the applicant would have an additional 30 days to make representations and submit undertakings in an effort to secure approval). The Arrangement is subject to review under the Investment Canada Act. On June 12, 2006, Acquisition Sub filed an application for review under the Investment Canada Act seeking the approval of the Minister of Industry for the acquisition of control of Hummingbird. Acquisition Sub cannot acquire Hummingbird unless it has first received the approval of the Minister of Industry for the acquisition of control of Hummingbird. If no notice is sent to the applicant by the Minister of Industry within the 45 day period or the extended period, as the case may be, the Arrangement is deemed to be approved by the Minister of Industry. Stock Exchange De-Listing and Reporting Issuer Status The Common Shares are expected to be de-listed from the TSX and NASDAQ on or following the Effective Date. Hummingbird will also seek to be deemed to have ceased to be a reporting issuer under the securities legislation of each of the provinces in Canada under which it is currently a reporting issuer (or equivalent) and will terminate the registration of its Common Shares under the United States Securities Exchange Act of 1934, as amended. DISSENTING HOLDERS' RIGHTS Section 190 of the CBCA provides registered shareholders of a corporation with the right to dissent from certain resolutions that effect extraordinary corporate transactions or fundamental corporate changes. The Interim Order expressly provides Registered Shareholders with the right to dissent from the Arrangement Resolution pursuant to section 190 of the CBCA, with modifications to the provisions of section 190 as provided in the Plan of Arrangement and the Interim Order ("Dissent Rights"). Any Registered Shareholder who dissents from the Arrangement Resolution in compliance with section 190 of the CBCA, as modified by the Plan of Arrangement and the Interim Order, will be entitled, in the event the Arrangement becomes effective, to be paid the fair value of Common Shares held by such Dissenting Holder determined as of the close of business on the day before the day the Arrangement Resolution is adopted. Shareholders are cautioned that fair value could be determined to be less than the $26.75 payable pursuant to the terms of the Arrangement. Section 190 of the CBCA provides that a shareholder may only make a claim under that section with respect to all of the shares of a class held by the shareholder on behalf of any one beneficial owner and registered in the shareholder's name. One consequence of this provision is that only a Registered Shareholder may exercise the Dissent Rights in respect of Common Shares that are registered in that Shareholder's name. In many cases, shares beneficially owned by a Non-Registered Holder are registered either (a) in the name of an Intermediary or (b) in the name of a clearing agency (such as CDS) of which the Intermediary is a participant. Accordingly, a Non-Registered Shareholder will not be entitled to exercise its Dissent Rights directly (unless the shares are re-registered in the Non-Registered Shareholder's name). A Non-Registered Shareholder who wishes to exercise Dissent Rights should immediately contact the Intermediary with whom the Non-Registered Shareholder deals in respect of its shares and either (i) instruct the Intermediary to exercise the Dissent Rights on the Non-Registered Shareholder's behalf (which, if the Common Shares are registered in the name of CDS or other clearing agency, may require that such Common Shares first be re-registered in the name of the Intermediary), or (ii) instruct the Intermediary to re-register such Common Shares in the name of the Non-Registered Shareholder, in which case the Non-Registered Shareholder would be able to exercise the Dissent Rights directly. A Registered Shareholder who wishes to dissent must provide a Dissent Notice to Hummingbird (a) at 1 Sparks Avenue, Toronto, Ontario, M2H 2W1 (Attention: Corporate Secretary) or (b) by facsimile transmission to (416) 496-2207 (Attention: Corporate Secretary) to be received not later than 5:00 p.m. (Toronto time) on July 19, 2006 (or 5:00 p.m. (Toronto time) on the day which is two business days immediately preceding any adjourned or postponed Meeting). Failure to strictly comply with these Dissent Procedures may result in the loss or unavailability of the right to dissent. The filing of a Dissent Notice does not deprive a Registered Shareholder of the right to vote at the Meeting. However, the CBCA provides, in effect, that a Registered Shareholder who has submitted a Dissent Notice and who votes FOR the Arrangement Resolution will no longer be considered a Dissenting Holder with respect to that class of shares voted FOR the Arrangement Resolution, being the Common Shares. The CBCA does not provide, and Hummingbird will not assume, that a proxy submitted instructing the proxyholder to vote against the Arrangement Resolution, a vote against the Arrangement Resolution or an abstention constitutes a Dissent Notice, but a Registered Shareholder need not vote its Common Shares against the Arrangement Resolution in order to dissent. Similarly, the revocation of a proxy conferring authority on the proxyholder to vote FOR the Arrangement Resolution does not constitute a Dissent Notice. However, any proxy granted by a Registered Shareholder who intends to dissent, other than a proxy that instructs the proxyholder to vote against the Arrangement Resolution, should be validly revoked in order to prevent the proxyholder from voting such Common Shares in favour of the Arrangement Resolution and thereby causing the Registered Shareholder to forfeit its Dissent Rights. See "Information Concerning the Meeting and Voting". Hummingbird (or its successor) is required, within ten (10) days after Shareholders adopt the Arrangement Resolution, to notify each Dissenting Holder that the Arrangement Resolution has been adopted. Such notice is not required to be sent to any Shareholder who voted for the Arrangement Resolution or who has withdrawn its Dissent Notice. A Dissenting Holder who has not withdrawn its Dissent Notice prior to the Meeting must then, within twenty (20) days after receipt of notice that the Arrangement Resolution has been adopted, or if the Dissenting Holder does not receive such notice, within twenty (20) days after learning that the Arrangement Resolution has been adopted, send to Hummingbird c/o the Transfer Agent a written notice (a "Demand for Payment") containing its name and address, the number of Common Shares in respect of which he or she dissents (the "Dissenting Common Shares"), and a demand for payment of the fair value of such Common Shares. Within thirty (30) days after sending the Demand for Payment, the Dissenting Holder must send to Hummingbird or the Transfer Agent certificates representing Common Shares in respect of which he or she dissents. The Transfer Agent will endorse on share certificates received from a Dissenting Holder a notice that the holder is a Dissenting Holder and will forthwith return the share certificates to the Dissenting Holder. A Dissenting Holder who fails to make a Demand for Payment in the time required or to send certificates representing Dissenting Common Shares has no right to make a claim under section 190 of the CBCA. Under section 190 of the CBCA, after sending a Demand for Payment, a Dissenting Holder ceases to have any rights as a Shareholder in respect of its Dissenting Common Shares other than the right to be paid the fair value of the Dissenting Common Shares as determined pursuant to the Interim Order, unless (i) the Dissenting Holder withdraws its Dissent Notice before Acquisition Sub (or its successor) makes an Offer to Pay, or (ii) Acquisition Sub (or its successor) fails to make an Offer to Pay in accordance with subsection 190(12) of the CBCA and the Dissenting Holder withdraws the Demand for Payment, in which case the Dissenting Holder's rights as a Shareholder will be reinstated. Pursuant to the Plan of Arrangement, in no case shall Hummingbird or any other person be required to recognize any Dissenting Holder as a Shareholder after the Effective Date, and the names of such Shareholders shall be deleted from the list of Registered Shareholders at the Effective Date. Pursuant to the Plan of Arrangement, Dissenting Holders who are ultimately determined to be entitled to be paid fair value for their Dissenting Common Shares shall be deemed to have transferred such Dissenting Common Shares to Acquisition Sub at the Effective Time. Pursuant to the Plan of Arrangement, Dissenting Holders who are ultimately determined not to be entitled, for any reason, to be paid fair value for their Dissenting Common Shares, shall be deemed to have participated in the Arrangement on the same basis as any non-Dissenting Holder as at and from the Effective Date. Amalco is required, not later than seven (7) days after the later of the Effective Date and the date on which a Demand for Payment is received from a Dissenting Holder, to send to each Dissenting Holder who has sent a Demand for Payment an Offer to Pay for its Dissenting Common Shares in an amount considered by the Board to be the fair value of the Common Shares, accompanied by a statement showing the manner in which the fair value was determined. Every Offer to Pay must be on the same terms. Amalco must pay for the Dissenting Common Shares of a Dissenting Holder within ten (10) days after an Offer to Pay has been accepted by a Dissenting Holder, but any such offer lapses if Amalco does not receive an acceptance within thirty (30) days after the Offer to Pay has been made. If Acquisition Sub (or its successor) fails to make an Offer to Pay for a Dissenting Holder's Common Shares, or if a Dissenting Holder fails to accept an Offer to Pay that has been made, Amalco may, within fifty (50) days after the Effective Date or within such further period as a court may allow, apply to a court to fix a fair value for the Common Shares of Dissenting Holders. If Amalco fails to apply to a court, a Dissenting Holder may apply to a court for the same purpose within a further period of twenty (20) days or within such further period as a court may allow. A Dissenting Holder is not required to give security for costs in such an application. If Amalco or a Dissenting Holder makes an application to court, Amalco will be required to notify each affected Dissenting Holder of the date, place and consequences of the application and of its right to appear and be heard in person or by counsel. Upon an application to a court, all Dissenting Holders who have not accepted an Offer to Pay will be joined as parties and be bound by the decision of the court. Upon any such application to a court, the court may determine whether any person is a Dissenting Holder who should be joined as a party, and the court will then fix a fair value for the Dissenting Common Shares of all Dissenting Holders. The final order of a court will be rendered against Amalco in favour of each Dissenting Holder for the amount of the fair value of its Dissenting Common Shares as fixed by the court. The court may, in its discretion, allow a reasonable rate of interest on the amount payable to each Dissenting Holder from the Effective Date until the date of payment. Registered Shareholders who are considering exercising Dissent Rights should be aware that there can be no assurance that the fair value of their Common Shares as determined under the applicable provisions of the CBCA (as modified by the Plan of Arrangement and the Interim Order) will be more than or equal to the consideration under the Arrangement. In addition, any judicial determination of fair value will result in delay of receipt by a Dissenting Holder of consideration for such Dissenting Holder's Dissenting Common Shares. The foregoing is only a summary of the dissenting holder provisions of the CBCA (as modified by the Plan of Arrangement and the Interim Order), which are technical and complex. A complete copy of section 190 of the CBCA is attached as Appendix I to this Circular. It is recommended that any Registered Shareholder wishing to avail itself of its Dissent Rights under those provisions seek legal advice, as failure to comply strictly with the provisions of the CBCA (as modified by the Plan of Arrangement and the Interim Order) may prejudice its Dissent Rights. For a general summary of certain income tax implications to a Dissenting Holder, see "Certain Tax Considerations for Shareholders".

CERTAIN TAX CONSIDERATIONS FOR SHAREHOLDERS Certain Canadian Federal Income Tax Considerations In the opinion of Goodmans LLP, Canadian counsel to Hummingbird, the following summary describes the principal Canadian federal income tax considerations generally applicable to a Shareholder who, for the purposes of the Tax Act and at all relevant times, holds its Common Shares as capital property, deals at arm's length with Hummingbird, Parent and Acquisition Sub, and is not affiliated with Hummingbird, Parent or Acquisition Sub. Generally, Common Shares will be capital property to a Shareholder unless the Common Shares are held or were acquired in the course of carrying on a business of buying and selling securities or as part of an adventure or concern in the nature of trade. Certain Shareholders who are residents of Canada for purposes of the Tax Act and whose Common Shares might not otherwise be capital property may, in some circumstances, be entitled to make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have such Common Shares and every other "Canadian security" (as defined in the Tax Act) owned by them deemed to be capital property in the taxation year of the election and in all subsequent taxation years. Such Shareholders should consult their own tax advisors for advice with respect to whether an election under subsection 39(4) of the Tax Act is available or advisable in their particular circumstances. This summary is based upon the current provisions of the Tax Act, the regulations thereunder (the "Regulations") and counsel's understanding of the current administrative policies and assessing practices of the CRA made publicly available prior to the date hereof. This summary also takes into account all specific proposals to amend the Tax Act and the Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Proposed Amendments") and assumes that all Proposed Amendments will be enacted in the form proposed. However, no assurances can be given that the Proposed Amendments will be enacted as proposed, or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative policies or assessing practices, whether by legislative, regulatory, administrative or judicial action or decision, nor does it take into account provincial, territorial or foreign tax legislation or considerations, which may be different from those discussed in this summary. This summary assumes that the Common Shares will be listed on the TSX or NASDAQ at the time they are disposed of by a Shareholder, pursuant to the Plan of Arrangement (the "Disposition Time"). This summary is not applicable to a Shareholder (i) that is, for the purposes of certain rules in the Tax Act applicable to securities held by financial institutions, a "financial institution" (as defined in the Tax Act), or (ii) who acquired its Common Shares upon the exercise of an Option. This summary does not address the consequences of the Arrangement to Optionholders. Each Optionholder is urged to consult its own tax advisors concerning the tax consequences of the Arrangement for them. Furthermore, this summary does not take into account the tax consequences of participating in the holding company alternative as described under "Holding Company Alternative." This summary is of a general nature only and is not, and is not intended to be, legal or tax advice to any particular Shareholder. This summary is not exhaustive of all Canadian federal income tax considerations. Accordingly, Shareholders should consult their own tax advisors with respect to the Canadian federal income tax consequences of the Arrangement having regard to their own particular circumstances. Currency Translation All amounts relevant to the computation of income under the Tax Act must be reported in Canadian dollars. Any amount that is expressed or denominated in a currency other than Canadian dollars, including adjusted cost base and proceeds of disposition, must be converted into Canadian dollars based on the spot currency exchange rate prevailing on the date each such amount arises. Shareholders Resident in Canada The following portion of this summary is generally applicable to a Shareholder who is a Resident Shareholder. Disposition of Common Shares A Resident Shareholder who disposes of Common Shares under the Arrangement will realize a capital gain (or capital loss) equal to the amount by which the cash received by the Resident Shareholder under the Arrangement, net of any reasonable costs of disposition, exceeds (or is less than) the adjusted cost base of the Common Shares to the Resident Shareholder. Generally, a Resident Shareholder is required to include in computing its income for a taxation year one-half of the amount of any capital gain (a "taxable capital gain") realized by the Resident Shareholder in the year. A Resident Shareholder is required to deduct one-half of the amount of any capital loss (an "allowable capital loss") realized in a taxation year from taxable capital gains realized by the Resident Shareholder in the year, and allowable capital losses in excess of taxable capital gains may be carried back and deducted in any of the three (3) preceding taxation years or carried forward and deducted in any subsequent taxation year against net taxable capital gains realized by the Resident Shareholder in such years, to the extent and in the circumstances prescribed by the Tax Act. The amount of any capital loss realized by a Resident Shareholder that is a corporation on the disposition of a Common Share may be reduced by the amount of any dividends received (or deemed to be received) by it on such Common Share to the extent and under the circumstances prescribed by the Tax Act. Similar rules may apply where the corporation is a member of a partnership or a beneficiary of a trust that owns Common Shares or where a partnership or trust of which a corporation is a member or a beneficiary is a member of a partnership or a beneficiary of a trust that owns Common Shares. Resident Shareholders to whom these rules may apply should consult their own tax advisors. A Resident Shareholder that is throughout the year a "Canadian-controlled private corporation" (as defined in the Tax Act) may be liable for a refundable tax of 6 (2)/3% on its "aggregate investment income", which is defined to include an amount in respect of taxable capital gains. Capital gains realized by an individual or a trust, other than certain trusts, may give rise to alternative minimum tax under the Tax Act. Resident Shareholders should consult their own advisors with respect to alternative minimum tax provisions. Dissenting Holders A Resident Shareholder who exercises Dissent Rights (a "Resident Dissenting Holder") will transfer such holder's Common Shares to Acquisition Sub in exchange for payment by Acquisition Sub (or Amalco, as its successor) of the fair value of such Common Shares. In general, a Resident Dissenting Holder will realize a capital gain (or capital loss) equal to the amount by which the cash received by the Resident Dissenting Holder in respect of the fair value of such holder's Common Shares (other than in respect of interest awarded by a court), net of any reasonable costs of disposition, exceeds (or is less than) the adjusted cost base to the Resident Dissenting Holder of such Common Shares. See "Disposition of Common Shares" above. Interest awarded by a court to a Resident Dissenting Holder will be included in the shareholder's income for the purposes of the Tax Act. Resident Dissenting Holders should consult their own tax advisors. Shareholders Not Resident in Canada The following portion of this summary is applicable to a Shareholder who is a Non-Resident Shareholder. Special rules, which are not discussed in this summary, may apply to a Non-Resident Shareholder that is either an insurer carrying on business in Canada and elsewhere or an "authorized foreign bank" for the purposes of the Tax Act. Such Non-Resident Shareholders should consult their own tax advisors. Disposition of Common Shares A Non-Resident Shareholder will not be subject to tax under the Tax Act on any capital gain realized on the disposition of Common Shares under the Arrangement unless the Common Shares are "taxable Canadian property" (within the meaning of the Tax Act) to the Non-Resident Shareholder at the Disposition Time. Generally, Common Shares will not be taxable Canadian property to a Non-Resident Shareholder at the Disposition Time provided that (a) the Common Shares are listed on a prescribed stock exchange (which includes the TSX and NASDAQ) at that time, and (b) the Non-Resident Shareholder, persons with whom the Non-Resident Shareholder does not deal at arm's length, or the Non-Resident Shareholder together with all such persons, has not owned 25% or more of the issued shares of any class or series of the capital stock of Hummingbird at any time during the sixty (60) month period that ends at the Disposition Time. Notwithstanding the foregoing, Common Shares may be deemed to be taxable Canadian property in certain circumstances specified in the Tax Act. Even if Common Shares are considered to be taxable Canadian property of a Non-Resident Shareholder at the Disposition Time, any capital gain realized by the Non-Resident Shareholder on a disposition of the Common Shares under the Arrangement may be exempt from tax under the Tax Act pursuant to the terms of an applicable income tax treaty. Non-Resident Shareholders should consult their own tax advisors with respect to the availability of any relief under the terms of any applicable income tax treaty in their particular circumstances. In the event that the Common Shares constitute taxable Canadian property to a Non-Resident Shareholder and any capital gain realized by the Non-Resident Shareholder on the disposition of Common Shares under the Arrangement is not exempt from tax under the Tax Act by virtue of an applicable income tax treaty, then the tax consequences described above under the heading "Shareholders Resident in Canada -- Disposition of Common Shares" will generally apply. Dissenting Holders A Non-Resident Shareholder who exercises Dissent Rights (a "Non-Resident Dissenting Holder") will transfer such holder's Common Shares to Acquisition Sub in exchange for payment by Acquisition Sub (or Amalco, as its successor) of the fair value of such Common Shares. In general, the tax treatment of a Non-Resident Dissenting Holder will be similar to that of a Non-Resident Shareholder who participates in the Arrangement. See "Disposition of Common Shares" above. The amount of any interest awarded by a court to a Non-Resident Dissenting Holder will be subject to Canadian withholding tax at a rate of 25% unless the rate is reduced under the provisions of an applicable income tax treaty. Non-Resident Dissenting Holders should consult their own tax advisors with respect to the availability of any relief under the terms of an applicable income tax treaty in their particular circumstances. Certain Material United States Federal Income Tax Considerations The following summary describes certain material U.S. federal income tax consequences of the Arrangement to Shareholders. This discussion does not purport to consider all aspects of U.S. federal income taxation that might be relevant to Shareholders. This discussion is based on current provisions of the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, proposed regulations, Internal Revenue Service rulings and pronouncements and judicial decisions currently in effect, all of which are subject to change at any time, possibly with retroactive effect. Hummingbird has not sought and will not seek any rulings from the Internal Revenue Service with respect to the consequences discussed below. The discussion below is not binding on the Internal Revenue Service or the courts. The discussion applies only to Shareholders who hold shares as capital assets within the meaning of the Code. This discussion does not apply to certain types of Shareholders (such as insurance companies, tax-exempt organizations, financial institutions, persons who acquired Common Shares pursuant to the exercise of an employee stock option or right or otherwise as compensation, traders, broker-dealers, persons who hold or have held Common Shares as part of a straddle or a hedging, integrated constructive sale or conversion transaction for tax purposes, pass-through entities and investors in such entities, mutual and common trust funds, regulated investment companies, real estate investment trusts, persons that actually or constructively hold (or have ever held) 10% or more of the total voting power of all outstanding Hummingbird voting stock, or holders who acquired their Common Shares upon the conversion or exchange of other stock or securities) who may be subject to special rules. This discussion does not address any aspect of state, local or foreign or other tax Laws, or estate or gift tax considerations, or the alternative minimum tax. For purposes of this discussion, a "U.S. holder" is (a) a citizen or individual resident of the United States, (b) a corporation or other entity taxable as a corporation for U.S. federal income tax purposes organized in the United States or under the laws of the United States or any political subdivision thereof, (c) a trust if a United States court is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or that was in existence on August 20, 1996 and that has a valid election in effect under applicable United States Treasury Regulations to be treated as a U.S. person, or (d) an estate that is subject to U.S. federal income tax on its income regardless of its source. A "non-U.S. holder" is a beneficial owner of Common Shares that is not a U.S. holder. If a partnership holds Common Shares, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. A partner in a partnership that is a beneficial owner of Common Shares should consult its own tax advisor. THE MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE FOR GENERAL INFORMATION PURPOSES ONLY AND ARE NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE ARRANGEMENT. BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, HUMMINGBIRD STRONGLY URGES SHAREHOLDERS TO CONSULT WITH THEIR TAX ADVISOR REGARDING THE APPLICABILITY OF THE RULES DISCUSSED BELOW TO THEM AND THE PARTICULAR TAX EFFECTS TO THEM OF THE ARRANGEMENT, INCLUDING THE APPLICATION OF STATE, LOCAL AND FOREIGN TAX LAWS. TO ENSURE COMPLIANCE WITH UNITED STATES TREASURY DEPARTMENT CIRCULAR 230, SHAREHOLDERS ARE HEREBY NOTIFIED THAT: (A) ANY DISCUSSION OF UNITED STATES FEDERAL TAX ISSUES IN THIS CIRCULAR IS NOT INTENDED OR WRITTEN TO BE RELIED UPON, AND CANNOT BE RELIED UPON BY SUCH SHAREHOLDERS, FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED ON SUCH SHAREHOLDERS UNDER THE CODE; (B) SUCH DISCUSSION IS BEING USED IN CONNECTION WITH THE PROMOTION OR MARKETING (WITHIN THE MEANING OF CIRCULAR 230) OF THE TRANSACTIONS OR MATTERS ADDRESSED HEREIN; AND (C) EACH SHAREHOLDER SHOULD SEEK ADVICE BASED ON ITS PARTICULAR CIRCUMSTANCES FROM AN INDEPENDENT TAX ADVISOR. Certain Material Federal Income Tax Considerations for U.S. Holders of Common Shares The receipt of cash by a U.S. holder for Common Shares pursuant to the Arrangement will be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. holder who surrenders Common Shares for cash pursuant to the Arrangement will recognize a capital gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount of cash received and the U.S. holder's adjusted tax basis in the shares surrendered. Gain or loss will be determined separately for each block of shares (i.e., shares acquired at the same cost in a single transaction) surrendered for cash pursuant to the Arrangement. Provided that Hummingbird is not a passive foreign investment company (as described below), if the holding period in Common Shares surrendered pursuant to the Arrangement is greater than one year as of the closing date of the Arrangement, the gain or loss will be long-term capital gain or loss. The deductibility of a capital loss is subject to limitations under the Code. Passive Foreign Investment Company The Code provides special, generally adverse, rules regarding certain distributions received by U.S. persons with respect to, and sales, exchanges and other dispositions, of shares of stock of, a "passive foreign investment company" ("PFIC"). A foreign corporation is treated as a PFIC for any taxable year if 75% or more of its gross income for the taxable year is passive income or the average percentage of its assets, generally by value, that produce or are held for the production of passive income is at least 50%. If Hummingbird were to be classified as a PFIC for the taxable year that includes the closing of the Arrangement or any other prior taxable year included in a U.S. holder's holding period for the Common Shares, the U.S. holder would generally be required to treat any gain recognized on the surrender of Common Shares for cash pursuant to the Arrangement as ordinary income and pay an interest charge on the value of the deferral of their U.S. federal income tax attributable to such gain, subject to certain mitigation rules. Hummingbird believes that it will not be a PFIC for its current taxable year and has not been a PFIC in any past year. However, the determination of whether a company is a PFIC is a factual determination, and no assurance can be provided that Hummingbird will not be treated as a PFIC for the current year or in any past year. U.S. holders are strongly urged to consult their tax advisors regarding the status of Hummingbird as a PFIC and the U.S. federal income tax consequences thereof. Backup federal withholding tax generally will be withheld at a rate of 28% from all cash payments to which a U.S. holder of Common Shares is entitled pursuant to the Arrangement, unless the U.S. holder (a) qualifies for certain exempt categories, including corporations and financial institutions, or (b) provides a certified taxpayer identification number on Form W-9 or Substitute Form W-9 and otherwise complies with backup withholding rules. Backup withholding is not an additional tax, but an advance payment. Any amounts withheld under the backup withholding rules will be refunded or allowed as a credit against the U.S. holder's U.S. federal income tax liability, if any, provided that the required information or appropriate claim for refund is filed with the Internal Revenue Service. Federal Income Tax Considerations for Non-U.S. Holders of Common Shares The receipt of cash by a non-U.S. holder for Common Shares will not be subject to U.S. federal income tax, provided that: o any gain or loss is not effectively connected with the conduct by that non-U.S. holder of a trade or business within the United States; and o in the case of an individual, the non-U.S. holder has not been present in the United States for 183 days or more during the taxable year in which the Arrangement is effected and certain other conditions exist. Non-U.S. holders may be required to provide an IRS Form W-8BEN or other appropriate IRS Form W-8. A failure to properly complete and furnish the appropriate IRS Form W-8 may result in backup federal withholding tax at a rate of 28% on the proceeds otherwise payable to the non-U.S. holder pursuant to the Arrangement. LEGAL MATTERS Certain legal matters in connection with the Arrangement will be passed upon by Goodmans LLP, as Canadian counsel, and Skadden, Arps, Slate, Meagher & Flom LLP, as U.S. counsel, on behalf of Hummingbird.

Copies of the articles and by- laws of Hummingbird furnished to Parent are accurate and complete and have not been amended or superseded and no steps or proceedings have been taken or are pending or contemplated to amend or supersede such constating documents.

(2) Hummingbird shall, and shall cause the officers, directors, employees, representatives and agents of Hummingbird and its subsidiaries to, immediately terminate any existing discussions or negotiations with any parties (other than Parent) with respect to any proposal that constitutes, or may reasonably be expected to constitute, an Acquisition Proposal.

Hummingbird shall immediately following the public announcement by the Parties of this Agreement request the return or destruction of all information provided to any third party which, at any time since January 1, 2005, has entered into a confidentiality agreement with Hummingbird relating to a potential Acquisition Proposal except to the extent that a request has previously been made that such information be returned or destroyed, and, upon the request of Parent, shall use all commercially reasonable efforts to ensure that such requests are honoured.

Hummingbird shall keep Parent promptly and reasonably informed from time to time of the status, including any change to the material terms of any such Acquisition Proposal or inquiry. Such notice shall include or be accompanied by a copy of all documentation relating to any Acquisition Proposal and any amendment thereto and a description of all material terms of any oral or other communications related to any Acquisition Proposal, including the identity of the person making such Acquisition Proposal and such other details as Parent may reasonably request.

If Hummingbird receives a request for material non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal and the Board of Directors of Hummingbird determines that such proposal would reasonably likely be, if consummated in accordance with its terms, a Superior Proposal, then, and only in such case, the Board of Directors of Hummingbird may, subject to the execution by such person of a confidentiality agreement having substantially the same terms as the Confidentiality Agreement, provide such person with access in accordance with subsection (1) to such information regarding Hummingbird, acting reasonably, provided however that the person making the Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal, and provided further that Hummingbird sends immediately a copy of any such confidentiality agreement to Parent upon its execution and Parent is immediately provided with a list and copies of all information provided to such person not previously provided to Parent and is immediately provided with access to information similar to that which was provided to such person. (5) Hummingbird shall ensure that its officers and directors and those of its subsidiaries and any financial or other advisors, agents or representatives retained by it are aware of the provisions of this Section, and Hummingbird shall be responsible for any breach of this Section by any such person or its advisors or representatives. (6) Nothing contained in this Section 7.1 shall prohibit the Board of Directors of Hummingbird from making any disclosure to all of the Hummingbird Shareholders prior to the Outside Date if, in the good faith judgment of the Board of Directors of Hummingbird, after consultation with outside counsel, the failure to make such disclosure would be inconsistent with its fiduciary duties or would contravene applicable Laws (including Section 99 of the Securities Act (Ontario)), provided that any such disclosure that relates to an Acquisition Proposal shall be deemed to constitute a basis for termination of this Agreement by Parent pursuant to Section 8.2(1)(e) unless the Board of Directors of Hummingbird reaffirms its recommendation to the Hummingbird Shareholders to accept the Offer in such disclosure. 7.2 Right to Match (1) Subject to Section 7.2(2), Hummingbird covenants that it will not accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Superior Proposal (other than a confidentiality agreement permitted by Section 7.1(4)) unless: (a) Hummingbird has complied with its obligations under Section 7.1 and the other provisions of this Article 7 and has provided Parent with a copy of all material documentation and a summary of any material oral or other communications relating to the Superior Proposal (the "Superior Proposal Information"); (b) a period (the "Response Period") of five (5) business days shall have elapsed from the date on which Parent received both the Superior Proposal Information together with written notice from the Board of Directors of Hummingbird that the Board of Directors of Hummingbird determined, subject only to compliance with this Section 7.2, to accept, approve, recommend or enter into a binding agreement to proceed with the Superior Proposal Information; and (c) if the Response Period would not terminate on or before the date fixed for the Meeting, Hummingbird shall, upon the written request of Parent, adjourn the Meeting to a date selected by Parent that is not less than two nor more than 20 business days after the expiration of the Response Period. (2) During the Response Period, Parent will have the right, but not the obligation, to offer to amend the terms of the Transactions. The Board of Directors of Hummingbird will review any such proposal by Parent to amend the terms of the Transactions, including an increase in, or modification of, the consideration to be received by the holders of Hummingbird Shares, to determine whether the Acquisition Proposal to which Parent is responding would be a Superior Proposal when assessed against the Transactions as it is proposed by Parent to be amended. If the Board of Directors of Hummingbird does not so determine, the Board of Directors of Hummingbird will promptly reaffirm its recommendation of the Transactions as amended and Hummingbird will not implement the proposed Superior Proposal. If the Board of Directors of Hummingbird does so determine, Hummingbird may on termination of this Agreement in accordance with Section 8.2(1)(g) and payment of the fee to Parent pursuant to Section 7.3, approve, recommend, accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal. (3) Each successive amendment to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the holders of Hummingbird Shares shall constitute a new Acquisition Proposal for the purposes of this Section 7.2 and Parent shall be afforded a new Response Period in respect of each such Acquisition Proposal. 7.3 Certain Payments (1) Notwithstanding any other provision relating to the payment of fees, including the payment of brokerage fees, in the event that: (a) Parent has terminated this Agreement pursuant to Section 8.2(1)(e); (b) Hummingbird has terminated this Agreement pursuant to Section 8.2(1)(g); (c) (i) (A)(1) this Agreement has been terminated pursuant to Section 8.2(1)(h) or 8.2(1)(i) and (2) the Arrangement has failed to receive the requisite approval of the Hummingbird Shareholders in accordance with applicable Law; or (B)(1) this Agreement has been terminated pursuant to Section 8.2(1)(c), provided that in the case of a breach of a representation or warranty such breach was made knowingly by Hummingbird; (ii) an Acquisition Proposal has been negotiated or discussed with Hummingbird (directly or indirectly through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries), made or publicly announced or an inquiry to Hummingbird (directly or indirectly through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries) concerning an Acquisition Proposal has been made, in each case prior to the termination of this Agreement; and (iii) (A) an agreement or a letter of intent in respect of any Acquisition Proposal has been entered into by Hummingbird on or before the first anniversary of the termination of this Agreement and such Acquisition Proposal has been completed; or (B) any Acquisition Proposal, in respect of which Hummingbird has not entered into an agreement or a letter of intent, has been completed on or before the first anniversary of the termination of this Agreement; or (d) Hummingbird has breached its obligations under Section 7.1 or Section 7.2, then Hummingbird shall promptly, but in no event later than the Payment Deadline (defined below), make a payment to Holdco in the amount of $11,714,586 less any amounts paid to Holdco pursuant to Section 7.4 by wire transfer of immediately available funds to an account designated by Holdco. Hummingbird acknowledges that the agreements contained in this Section 7.3(1) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent, Holdco and Acquisition Sub would not enter into this Agreement. Notwithstanding anything to the contrary, this Section 7.3 shall survive completion of any and all of the Transactions. Payment Deadline means: the fifth business day following termination of this Agreement in the case of a payment to be made under Section 7.3(1)(a); the time of termination of this Agreement in the case of a payment to be made under Section 7.3(1)(b); the fifth business day following completion of an Acquisition Proposal in the case of a payment to be made under Section 7.3(1)(c); and the fifth business day following Holdco's request for payment in the case of a payment to be made under Section 7.3(1)(d). 7.4 Fees and Expenses (1) Subject to subsections (2) and (3) of this Section 7.4, each Party shall pay all fees, costs and expenses, including legal fees, accounting fees, financial advisory fees, regulatory fees, stock exchange fees, disbursements of advisors and printing and mailing costs, incurred by such Party in connection with this Agreement and the Transactions and any financing thereof. (2) In the event that: (a) this Agreement is terminated pursuant to Section 8.2(1)(a) or 8.2(1)(c); or (b) (i) this Agreement is terminated pursuant to Section 8.2(1)(h) or 8.2(1)(i); and (ii) the Arrangement has failed to receive the requisite approval of the Hummingbird Shareholders in accordance with applicable Law, then Hummingbird shall promptly, but in no event later than five business days following the request by Holdco, pay all of the charges and expenses incurred by Parent, Holdco and Acquisition Sub in connection with this Agreement and the Transactions and the financing thereof, subject to a maximum of $2,000,000 (which maximum amount will be reduced to $1,000,000 if the Agreement has been terminated pursuant to Section 8.2(1)(i) in circumstances where the Hummingbird Shareholders have voted on the Arrangement Resolution at the Meeting but the Arrangement Resolution failed to receive the requisite approval of at least two-thirds of the votes cast at the Meeting), as reimbursement to Parent, Holdco and Acquisition Sub payable by wire transfer of same day funds to or to the order of Holdco, provided however, that no payment under Section 7.4(2) shall be made if a payment has been made under Section 7.3. (3) Each Party acknowledges that the agreements contained in this Section 7.4 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, neither Party would enter into this Agreement. Notwithstanding anything to the contrary, this Section 7.4 shall survive completion of any and all of the Transactions. 7.5 Liquidated Damages and Injunctive Relief Each of the Parties acknowledges that all of the payment amounts set out in Sections 7.3 and 7.4 are payments of liquidated damages which are a genuine pre-estimate of the damages Parent, Acquisition Sub and Holdco, on the one hand, or Hummingbird, on the other hand (as the case may be) will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement and are not penalties. Each of the Parties irrevocably waives any right it may have to raise as a defense that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that, subject to Sections 7.3 and 7.4, payment of the amounts determined pursuant to Sections 7.3 and/or 7.4 in the manner provided in respect thereof is the sole monetary remedy of the Party receiving such payment. Nothing contained herein shall preclude a Party from seeking injunctive relief to restrain any breach or threatened breach of the covenants or agreements set forth in this Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith. 7.6 Access to Information; Confidentiality (1) From the date hereof until the earlier of the Effective Time and the termination of this Agreement, upon reasonable notice and subject to applicable Law, including pre-merger notification and other competition law requirements, Hummingbird shall, and shall cause its subsidiaries and their respective officers, directors, employees, independent auditors, accounting advisers and agents to, afford to Parent and to the officers, employees, agents and representatives of Parent such access as Parent may reasonably require at all reasonable times, including for the purpose of facilitating integration business planning, to their officers, employees, agents, properties, books, records and Contracts, and shall furnish Parent with all data and information as Parent may reasonably request. Parent and Hummingbird acknowledge and agree that information furnished pursuant to this Section shall be subject to the terms and conditions of the Confidentiality Agreement. (2) Parent and Hummingbird acknowledge that information received pursuant to this Section 7.6 may be personal information under applicable privacy and other Laws, or non-public or proprietary in nature and therefore all such information shall be deemed to be and shall be treated as confidential information for purposes of the Confidentiality Agreement. Parent and Hummingbird further acknowledge their obligation to maintain the confidentiality of such confidential information in accordance with the Confidentiality Agreement. If any material is withheld by Hummingbird or any of its subsidiaries because of the confidential nature of such material, or otherwise, Hummingbird or such subsidiary shall inform Parent as to the general nature of what is being withheld and such information may, in the sole discretion of Hummingbird, be disclosed to external advisors of Parent. 7.7 Insurance and Indemnification (1) Parent will, or will cause Acquisition Sub to, at Parent's option, either (a) maintain in effect without any reduction in scope or coverage for not less than six years from the Effective Date customary policies of directors' and officers' liability insurance providing protection no less favourable to the protection provided by the policies maintained by Hummingbird in favour of the directors and officers of Hummingbird and each of its subsidiaries which are in effect immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred prior to the Effective Time or (b) purchase as an extension of Hummingbird's current insurance policies, prepaid non cancellable run-off directors' and officers' liability insurance providing coverage comparable to that contained in Hummingbird's existing policy for six years from the Effective Time with respect to claims arising from or related to facts or events that occurred at or prior to the Effective Time. (2) Parent agrees that all rights to indemnification or exculpation existing in favour of the directors or officers of Hummingbird or any subsidiary of Hummingbird as at the date of the Confidentiality Agreement (the "Hummingbird D&O Rights") as provided in Hummingbird's articles or by-laws or as disclosed in Section 7.7 of the Disclosure Letter shall survive the transactions contemplated hereby and shall continue in full force and effect for a period of not less than six years from the Effective Time. For a period of six years from the Effective Date, Parent will, or will cause Acquisition Sub or Hummingbird to, perform the obligations of Hummingbird under the Hummingbird D&O Rights. (3) In the event Hummingbird or any of its successors or assigns (a) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (b) transfers all or substantially all of its properties and assets to any person, then, and in such case, proper provision shall be made so that such successors and assigns of Hummingbird or, at Parent's option, Parent, shall assume the obligations set forth in this Section 7.7. (4) This Section 7.7 shall survive the consummation of the Arrangement, is intended to benefit Hummingbird and each of its directors and officers and their respective heirs and personal representatives and shall be enforceable by such directors and officers and their respective heirs and personal representatives. ARTICLE 8 TERM, TERMINATION, AMENDMENT AND WAIVER 8.1 Term This Agreement shall be effective from the date hereof until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms. 8.2 Termination (1) This Agreement may, at any time prior to the Effective Time: (a) be terminated by Parent if there shall have occurred after the date hereof (or prior to such date to the extent that the relevant change, event, occurrence or development shall have been disclosed generally or to Parent only after the date of this Agreement) up to and including the Effective Date, a Material Adverse Effect in respect of Hummingbird; (b) be terminated either by Parent or by Hummingbird, if any Law makes the completion of the transactions contemplated by this Agreement illegal or otherwise prohibited; (c) subject to Section 8.2(3), be terminated by Parent, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of Hummingbird set forth in this Agreement or any such representation and warranty shall have become untrue after the date of this Agreement, such that Section 6.2(a) or 6.2(b) would not be satisfied; (d) subject to Section 8.2(3), be terminated by Hummingbird, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of Parent set forth in this Agreement or any such representation and warranty shall have become untrue after the date of this Agreement, such that Section 6.3(a) or 6.3(b) would not be satisfied; (e) be terminated by Parent, if the Board of Directors of Hummingbird shall have: (i) withdrawn, withheld, qualified or modified in a manner adverse to Parent its recommendation of this Agreement (it being understood that the taking of a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification), (ii) after being requested by Parent in writing, failed to reaffirm its recommendation of the Arrangement as promptly as practicable (but in any event within two (2) business days) after receipt of any written request to do so from Parent or (iii) approved or recommended an Acquisition Proposal or entered into a binding written agreement in respect of an Acquisition Proposal (other than a confidentiality agreement permitted by Section 7.1(4)); (f) be terminated by the mutual written consent of Parent and Hummingbird; (g) be terminated by Hummingbird, in order to enter into a binding written agreement with respect to a Superior Proposal (other than a confidentiality agreement permitted by Section 7.1(4)), subject to compliance with Sections 7.1 and 7.2 and provided that no termination under this Section 8.2(1)(g) shall be effective unless and until Hummingbird shall have paid to Parent the amount required to be paid pursuant to Section 7.3; (h) be terminated either by Parent or by Hummingbird, if the Effective Time shall not have occurred on or before the Outside Date; provided, that the right to terminate this Agreement pursuant to this Section 8.2(1)(h) shall not be available to any party that has breached in any material respect its obligations under this Agreement in any manner that shall have proximately contributed to the occurrence of the failure of the Effective Time to occur on or before such date; or (i) be terminated by Parent, if the Arrangement Resolution shall have failed to receive the requisite approval of at least two-thirds of the votes cast at the Meeting or at any adjournment or postponement thereof in accordance with the CBCA. (2) If this Agreement is terminated in accordance with the foregoing provisions of this Section, this Agreement shall forthwith become void and of no further force or effect and no Party shall have any further obligations hereunder except as provided in Sections 7.3 and 7.4 and the Confidentiality Agreement. (3) None of Parent, Acquisition Sub or Holdco or Hummingbird may elect to not consummate the transactions contemplated hereby pursuant to the conditions under Section 6.2(a), Section 6.2(b)(i), Section 6.3(a) or Section 6.3(b) (the "Specified Conditions") or to exercise the termination rights under Section 8.2(1)(c) (as it relates to Section 6.2(a) or Section 6.2(b)(i)) or Section 8.2(1)(d) (the "Specified Termination Rights") unless Parent or Hummingbird, as the case may be, has delivered a written notice to the other specifying in reasonable detail all breaches of covenants, agreements or representations and warranties which Parent or Hummingbird, as the case may be, is asserting as the basis for non-fulfilment of the applicable Specified Condition or the exercise of the applicable Specified Termination Right, as the case may be. If any such notice is delivered, provided that Parent or Hummingbird, as the case may be, is proceeding diligently to cure such matter and such matter is capable of being cured, the other may not terminate this Agreement until the earlier of the Outside Date and the expiration of a period of 30 days from such notice (and then only if such breach remains uncured). If such notice has been delivered prior to the date of the Special Meeting, such meeting shall be postponed until the expiry of such period. For greater certainty, in the event that such matter is cured within the time period referred to herein, this Agreement may not be terminated as a result of the cured breach. Also for greater certainty, this Section 8.2(3) does not apply to a Party electing to not consummate the transactions contemplated hereby pursuant to any condition precedent contained herein other than the Specified Conditions or exercising any termination rights herein other than the Specified Termination Rights. 8.3 Amendment This Agreement may be amended by the parties hereto by action taken by or on behalf of their respective boards of directors at any time prior to the Effective Time; provided, however, that, after receipt of approval of Hummingbird Shareholders there shall be made no amendment that by Law requires further approval by Hummingbird Shareholders at the Meeting without the further approval of such holders. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto. 8.4 Waiver Any Party may (a) extend the time for the performance of any of the obligations or acts of the other Party, (b) waive compliance with any of the other Party's agreements or the fulfilment of any conditions to its own obligations contained herein, or (c) waive inaccuracies in any of the other Party's representations or warranties contained herein or in any document delivered by the other Party; provided, however, that any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party and, unless otherwise provided in the written waiver, will be limited to the specific breach or condition waived.

(d) Any payment made by way of cheque by the Depositary on behalf of Acquisition Sub or Hummingbird that has not been deposited or has been returned to the Depositary or that otherwise remains unclaimed, in each case on or before the sixth anniversary of the Effective Date, shall cease to represent a right or claim of any kind or nature and the right of the Shareholder or Optionholder to receive the consideration for Hummingbird Shares or Hummingbird Options, as the case may be, pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Amalco for no consideration. 4.3 Lost Certificates In the event any certificate which immediately prior to the Effective Time represented one or more outstanding Hummingbird Shares that were transferred pursuant to Section 2.3 shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, cash deliverable in accordance with such holder's Letter of Transmittal. When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the Person to whom such cash is to be delivered shall as a condition precedent to the delivery of such cash, give a bond satisfactory to Amalco and the Depositary in such sum as Amalco may direct, or otherwise indemnify Amalco in a manner satisfactory to Amalco, against any claim that may be made against Acquisition Sub and Hummingbird with respect to the certificate alleged to have been lost, stolen or destroyed. 4.4 Withholding Rights Hummingbird, Acquisition Sub, Parent, Amalco and the Depositary and any affiliate of Hummingbird shall be entitled to deduct and withhold from any consideration otherwise payable to any Shareholder or Optionholder such amounts as Hummingbird, Acquisition Sub, Parent, Amalco or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the United States Internal Revenue Code of 1986 or any provision of federal, provincial, state, local or foreign tax law, in each case, as amended.

ARTICLE 6 INDEMNIFICATION 6.1 Obligations to Indemnify The Vendor agrees to indemnify and save harmless Parent, Linden Holdco, Acquisition Sub, Hummingbird and HoldCo (and their directors and officers, employees, advisors and agents) from all actions, claims, demands, processes, proceedings, losses, damages, liabilities, deficiencies, Taxes (whether or not such Taxes have been assessed or reassessed as at the date hereof), and any instalments with respect thereto, costs and expenses (including, without limitation, all legal and other professional fees and disbursements, interest, penalties and amounts paid in settlement) (collectively "Liabilities") whether resulting from a breach of contract, by the commission of a fault or otherwise suffered or incurred by Parent, Linden Holdco, Acquisition Sub, Hummingbird and HoldCo (and their directors, officers, employees and agents), the whole to be computed on an after-tax basis, as a result of or arising directly or indirectly out of or in connection with: (a) any breach by the Vendor of any of its representations, warranties, obligations or covenants contained in this Agreement or any certificate or document delivered pursuant hereto; (b) any Liability sustained, incurred, assumed or acquired by HoldCo on or before, or related to any matter occurring on or before, the purchase of the HoldCo Shares hereunder; and (c) this Agreement and the transactions contemplated hereby (including the negotiation, execution, delivery and performance of this Agreement), the Reorganization or the Winding Up, including all Liabilities which, as a result of the Reorganization or Winding Up, are assumed or incurred by Parent, Linden Holdco, Acquisition Sub, Hummingbird and HoldCo. 6.2 Notice of Claim In the event that a party to this Agreement (the "Indemnified Party") shall become aware of any claim, proceeding or other matter (a "Claim") in respect of which another party to this Agreement (the "Indemnifying Party") agreed to indemnify the Indemnified Party pursuant to this Agreement, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party. Such notice shall specify whether the Claim arises as a result of a claim by a person against the Indemnified Party (a "Third Party Claim") or whether the Claim does not so arise (a "Direct Claim"), and shall also specify with reasonable particularity (to the extent that the information is available) the factual basis for the Claim and the amount of the Claim, if known. If, through the gross negligence or wilful misconduct of the Indemnified Party, the Indemnifying Party does not receive notice of any Claim in time to contest effectively the determination of any liability susceptible of being contested, the Indemnifying Party shall be entitled to set off against the amount claimed by the Indemnified Party the amount of any Liabilities incurred by the Indemnifying Party resulting from the Indemnified Party's failure to give such notice on a timely basis. 6.3 Direct Claims With respect to any Direct Claim, following receipt of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have 30 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If both parties agree at or prior to the expiration of such 30-day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed upon amount of the Claim. 6.4 Third Party Claims With respect to any Third Party Claim, the Indemnified Party shall have the exclusive right, at the expense of the Indemnifying Party, to contest, settle or pay the amount claimed and to retain counsel and other experts or advisors selected by the Indemnified Party in its sole discretion in connection therewith; provided, however, that the Indemnified Party shall not settle any Third Party Claim without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed; provided, however, that the Indemnifying Party shall remain liable for the settlement amount even if any such consent is not obtained for any reason. If the Indemnified Party elects to assume such control, the Indemnifying Party shall have the right, at its sole expense, to participate in the negotiation, settlement or defence of such Third Party Claim. If any Third Party Claim is of a nature such that the Indemnified Party is required by applicable law to make a payment to any person (a "Third Party") with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment. If the amount of any liability of the indemnified Party under the Third Party Claim in respect of which such payment was made, as finally determined, is less than the amount that was paid by the Indemnifying Party to the Indemnified Party, the Indemnified Party shall, forthwith after receipt of the difference from the Third Party, pay the amount of such difference to the Indemnifying Party. 6.5 Reduction, Set-off, Payment and Co-operation The Indemnifying Party shall pay to the Indemnified Party all amounts for which the Indemnifying Party is liable pursuant to this Section 6 promptly after the Indemnified Party incurs the Liability in respect of which such liability arises. If such amount is not so paid, the Indemnified Party may deduct or set-off such amount from any obligation it may have to the Indemnifying Party. The Indemnified Party and the Indemnifying Party shall co-operate fully with each other with respect to Third Party Claims, and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available). ARTICLE 7 RELEASE 7.1 Release Each of the Vendor and HoldCo, together with their respective asssigns, estates, heirs, executors, administrators and holders of any beneficial interest in any of them (i) grants to Parent, Linden Holdco, Acquisition Sub and Hummingbird (and their respective successors, assigns, parent companies, subsidiaries, affiliated companies, and all such entities' present and former directors, officers, employees, advisors and agents) a full and final release from any and all Liabilities suffered or incurred as a result of or with respect to or in any way connected with the transactions contemplated hereby including the computation of "safe income" for purposes of the ITA and any relevant provincial tax legislation and any information in that regard provided by any of Parent, Linden Holdco, Acquisition Sub and Hummingbird (and their respective directors, officers, employees, advisors and agents) to the Vendor, the adequacy or completeness of any such information or the failure of any of Parent, Linden Holdco, Acquisition Sub and Hummingbird (and their respective directors, officers, employees, advisors and agents) to provide information with respect to the transactions contemplated hereby; and (ii) acknowledges it has relied exclusively on its own tax advisors and has not received or relied upon any statements or representations whatsoever from Parent, Linden Holdco, Acquisition Sub, Hummingbird or their respective affiliates or advisors. ARTICLE 8 NON-COMPLETION OF ARRANGEMENT 8.1 Non-Completion In the event the Arrangement Agreement is terminated with the result that the Transaction is not completed, the rights and benefits and obligations and responsibilities of Parent, Linden Holdco and Acquisition Sub contained in this Agreement shall automatically and without further action of the parties hereto terminate as of the same date as the termination of the Arrangement Agreement. In such event, Parent, Linden Holdco and Acquisition Sub shall have no right to enforce any such rights and benefits thereafter and this Agreement shall be read as if Parent, Linden Holdco and Acquisition Sub were not parties to the Agreement. Parent, Linden Holdco and Acquisition Sub shall have no liabilities in connection with this Agreement and shall maintain the benefit of the release of any indemnity for any costs incurred.

By: Name: Title: SYMPHONY TECHNOLOGY II-A, L.P. By: Symphony Technology II GP, LLC, general partner By: Name: Title: LINDEN MANAGEMENT CORPORATION By: Name: Title: LINDEN ACQUISITION LTD. By: Name: Title: SCHEDULE "A" The following is a list of agreements and transactions intended to implement the Holding Company Alternative: (i) the transfer by the Vendor to HoldCo of the Subject Shares in exchange for o common shares in the capital of HoldCo on a tax-deferred basis (to the extent possible) pursuant to subsection 85(1) of the ITA (and any analogous provision of any applicable provincial legislation); (ii) HoldCo will implement one or more increases to the stated capital account maintained in respect of its common shares; and (iii) the transfer by the Vendor to Hummingbird of all of the HoldCo Shares pursuant to this Holding Company Participation Agreement. SCHEDULE "B" GUARANTEE THIS GUARANTEE, dated as of June o, 2006, made by [Full legal name of guarantor] (the "Guarantor"), with its [address/principal place of business] at o, in favour of HUMMINGBIRD LTD. ("Hummingbird"), with its principal place of business at 1 Sparks Avenue, Toronto, Ontario M2H 2W1, SYMPHONY TECHNOLOGY II-A, L.P. ("Parent"), LINDEN MANAGEMENT CORPORATION ("Linden Holdco"), LINDEN ACQUISITION LTD. ("Acquisition Sub") and the directors officers, employees and agents (collectively the "Related Parties") of Hummingbird, Parent, Linden Holdco and Acquisition Sub (Hummingbird, Parent, Linden Holdco, Acquisition Sub and the Related Parties, together in each case with their respective successors and assigns, being collectively the "Creditors" and individually a "Creditor"). WHEREAS: A. o ("HoldCo"), o ("Vendor", and collectively with HoldCo, the "Debtors") Hummingbird, Parent, Linden Holdco and Acquisition Sub are parties to a Holding Company Participation Agreement dated as of o, 2006 (such agreement as it may from time to time be supplemented, amended, consolidated or restated being the "Participation Agreement") providing for the purchase by Hummingbird from the Vendor of the issued and outstanding common shares of HoldCo in consideration for the issue and allotment by Hummingbird to HoldCo of fully paid and non-assessable common shares of Hummingbird. B. The Guarantor directly or indirectly owns [shares] of the Vendor. C. A condition to Hummingbird completing the transactions provided for under the Participation Agreement is that the Guarantor execute and deliver this guarantee. D. All capitalized terms used but not defined in this guarantee have the meanings specified in the Participation Agreement. THIS GUARANTEE WITNESSES THAT, in consideration for Hummingbird completing the transactions provided for under the Participation Agreement and for other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged by the Guarantor), the Guarantor agrees to, with and in favour of each of the Creditors as follows: 1. Guarantee: The Guarantor hereby unconditionally and irrevocably guarantees to each of the Creditors the due and punctual payment and performance in full of all present and future indebtedness, liabilities and obligations of each of the Debtors under, pursuant to or in respect of the Participation Agreement and all certificates and documents delivered by each of the Debtors pursuant thereto or in connection therewith (collectively the "Participation Documents") (including without limitation all such indebtedness, liabilities and obligations arising as a result of, in connection with or in respect of a breach of covenant, or a breach of a representation or warranty, by a Debtor under a Participation Document or arising pursuant to or in respect of any indemnity liability or obligation of a Debtor contained in a Participation Document), and any ultimate unpaid balance thereof (collectively the "Liabilities"). 2. Demand for Payment: The Guarantor shall from time to time pay to Hummingbird for the account of the Creditors forthwith after written demand on the Guarantor from Hummingbird, at the address specified in such demand, the amount of the liability of the Guarantor hereunder specified in such demand (the Guarantor acknowledging that Hummingbird may make demand on the Guarantor on its own behalf and on behalf of any one or more of the other Creditors). All amounts payable hereunder by the Guarantor shall be paid in the currency in which the related amounts are owed by the applicable Debtor. The Guarantor hereby waives any and all presentments, demands, notices and protests in the enforcement of this guarantee, other than as may be required by applicable law. 3. Continuing Guarantee: This guarantee shall be a continuing guarantee and shall be binding as a continuing obligation of the Guarantor. For all purposes of the liability of the Guarantor hereunder including without limitation the calculation of the amount of the Liabilities at any time, every sum of money which is now or which may hereafter from time to time be due or owing to any Creditor by any Debtor (or would have become so due or owing were it not for the insolvency, bankruptcy, reorganization or winding-up of such Debtor) shall be deemed to be and to continue due and owing to such Creditor until the same shall be actually paid in cash to such Creditor, notwithstanding the insolvency, bankruptcy, reorganization or winding-up of such Debtor or any other event whatsoever. The Guarantor agrees that, if at any time all or any part of any payment previously applied by any Creditor to any of the Liabilities is or must be rescinded or returned by such Creditor for any reason whatsoever (including without limitation the insolvency, bankruptcy, reorganization or winding-up of a Debtor), such Liability shall, for the purpose of this guarantee, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence, notwithstanding such application by such Creditor, and this guarantee shall continue to be effective or be reinstated, as the case may be, as to such Liability, all as though such application had not been made. No assurance, security or payment which may be rescinded or avoided under any law relating to insolvency, bankruptcy, reorganization or winding-up and no release, settlement, discharge or arrangement which may have been given or made on the faith of any such assurance, security or payment shall prejudice or affect the right of the Creditors to recover from the Guarantor to the full extent of this guarantee as if such assurance, security, payment, release, settlement, discharge or arrangement had never been granted, given or made. Any such release, settlement, discharge or arrangement shall as between the Creditors and the Guarantor, be deemed to have been given or made upon the express condition that it shall become and be wholly void and of no effect if the assurance, security or payment on the faith of which it was made or given shall at any time thereafter be rescinded or avoided as aforesaid, to the intent so that the Creditors shall become and be entitled at any time after any such recission or avoidance to exercise all or any of the rights conferred upon the Creditors hereunder and of all other rights which by virtue and as a consequence of this guarantee the Creditors would have been entitled to exercise but for such release, settlement, discharge or arrangement. 4. Enforcing Rights Against Guarantor: The Guarantor hereby waives the benefits of division and discussion. Without limiting the foregoing, no Creditor shall be obliged to take any action or to exhaust any recourse against any Debtor, any other person, or any security held at any time by any Creditor, nor to value any security held by any Creditor, before requiring, or being entitled to, payment from, and to enforce its rights and remedies against, the Guarantor under this guarantee. No Creditor shall be obliged to marshall any assets in favour of the Guarantor. Any third party dealing with any Creditor shall not be concerned to see or inquire as to the validity of any demand under this guarantee. 5. Guarantee Absolute: (1) The liability of the Guarantor hereunder shall be absolute and unconditional and shall not be released, discharged, diminished, limited or in any way affected by any matter, act, failure to act, or circumstance whatsoever, including without limitation: (a) any lack of enforceability of any agreement between any Creditor and any Debtor or any document provided by any Debtor to any Creditor; (b) any failure on the part of any Debtor to carry out any rights or obligations under any agreement or document; (c) any change in the name, objects, powers, organization, share capital, constating documents, business, shareholders, directors or management of any Debtor; (d) any amalgamation, merger or consolidation of any Debtor into or with any other person or entity, or any sale, lease or transfer of all or any of the assets of any Debtor to any other person or entity; (e) any lack or limitation of power, incapacity or disability on the part of any Debtor or any of its directors, officers, shareholders, partners, employees or agents, or any other irregularity, defect or informality, or any fraud, on the part of any Debtor or any of its directors, officers, shareholders, employees or agents with respect to any or all of the Liabilities; (f) any impossibility, impracticability, frustration of purpose, illegality, force majeure or act of government or governmental authority; (g) the insolvency, bankruptcy, reorganization, winding-up or financial condition of any Debtor or any other person at any time; (h) any loss of or in respect of any security held by or on behalf of any Creditor, whether occasioned through the fault of a Creditor or otherwise; (i) any law, regulation, limitation period or other matter or circumstance which might otherwise constitute a defence available to, or a discharge of, a Debtor with respect to any or all of the Liabilities; (j) any loss or impairment of any right of the Guarantor to subrogation, reimbursement or contribution, whether or not as a result of any action taken or omitted to be taken by any Creditor; and (k) anything done, omitted to be done, suffered or permitted by any Creditor in connection with all or any of the Liabilities or otherwise or in connection with any security held by or on behalf of any Creditor (whether relating to the Liabilities or otherwise), or which might otherwise operate to release, discharge, diminish or limit in any way the liability of, or otherwise provide a defence to, a guarantor or surety. (2) The Creditors may, with respect to all or any of the Liabilities and without releasing, discharging, limiting or otherwise affecting in whole or in part the Guarantor's liability hereunder: (a) amend, alter or vary any of their agreements with any of the Debtors or any other person; (b) grant time, renewals, extensions, indulgences, releases and discharges to any Debtor or any other person; (c) increase or reduce the rate of interest on all or any of the Liabilities; (d) alter, compromise, accelerate, extend or change the time or manner for payment by any Debtor of, or by any other person or persons liable to the Creditors in respect of any or all of the Liabilities; (e) take or abstain from taking security from any Debtor or any other person or from completing or perfecting any security taken; (f) release or add one or more guarantors or sureties, accept additional or substituted security, or release or subordinate any security; (g) accept compromises from any Debtor or any other person; (h) apply all money at any time received from any Debtor or from any person other than the Guarantor or from any security upon such part of the Liabilities as the Creditors may see fit, and change any such application from time to time in their discretion, or keep such money in a separate account for such period as the Creditors may determine without application to the Liabilities; and (i) otherwise deal with the Debtors, the Guarantor and all other persons and security as the Creditors may determine. The Creditors may apply all money at any time received from the Guarantor hereunder upon such part of the Liabilities as the Creditors may see fit, and may change any such application from time to time in their discretion. 6. Indemnity: If any amount in respect of the Liabilities is not recoverable from the Guarantor hereunder on the basis of a guarantee, then, notwithstanding any other provision hereof, (a) the Guarantor shall be liable hereunder as principal debtor in respect of the due payment of such amount, and shall pay such amount to Hummingbird for the benefit of the Creditors after demand as herein provided, and (b) the Guarantor shall indemnify and saves each of the Creditors harmless from and against all losses, costs, damages, expenses, claims and liabilities that such Creditor may suffer or incur in connection with or in respect of any failure by the applicable Debtor for any reason to pay or perform any such Liability and shall pay the amount of such loss, cost, damage, expense, claim or liability to Hummingbird for the benefit of the applicable Creditor after written demand for same by Hummingbird. 7. Conclusive Statement: Any account settled or stated by or between a Creditor and a Debtor at any time respecting the Liabilities shall be prima facie evidence that the balance or amount thereof appearing due to the applicable Creditor is so due. 8. Stay of Acceleration, etc.: If acceleration of the time for payment, or the liability of a Debtor to make any payment, of any amount specified to be payable by a Debtor in respect of the Liabilities is stayed, prohibited or otherwise affected upon the insolvency, bankruptcy, reorganization or winding-up of such Debtor or any moratorium affecting the payment of the Liabilities by such Debtor, all such amounts otherwise subject to acceleration or payment shall nonetheless be deemed for all purposes of this guarantee to be and to become due and payable by such Debtor and shall be payable by the Guarantor hereunder forthwith after demand by Hummingbird. 9. Subrogation, etc.: Until the Liabilities have been indefeasibly paid in full, the Guarantor shall not exercise or enforce any right of subrogation against any Debtor. In case of the insolvency, bankruptcy, reorganization or winding-up of a Debtor (whether voluntary or compulsory) or in the event that a Debtor shall make a bulk sale of any assets or scheme of arrangement with creditors, all dividends and other payments which may be due or payable to the Guarantor are hereby assigned and transferred to and shall be due and paid to Hummingbird for the benefit of the Creditors on account of the Liabilities, and for such payment to Hummingbird this shall be a sufficient warrant and authority to any person making the same. The Guarantor shall continue to be liable under this guarantee for any balance of the Liabilities which may be owing to the Creditors by a Debtor, and in the event of the valuation by the Creditors of any of their security and/or retention thereof by the Creditors in accordance with the Bankruptcy and Insolvency Act (Canada) or any other applicable legislation, such valuation and/or continuation shall not as between the Creditors and the Guarantor, be considered as a purchase of such security, or as payment or satisfaction or reduction of all or any part of the Liabilities. 10. Amounts Owed by Debtors. All present and future indebtedness and liabilities of each of the Debtors to the Guarantor are, effective from and after the date of any demand under this guarantee, postponed and subordinated to the full and final payment of all Liabilities, and until otherwise agreed in writing by the Creditors, all moneys received by the Guarantor in respect of any such indebtedness and liabilities at any such time shall be received as mandatary and agent for the Creditors, shall be kept by the Guarantor separate and apart from its other assets, and shall be paid over to Hummingbird on account of the Liabilities. 11. Alteration or Waiver: No alteration or waiver of this guarantee or of any of its terms, provisions or conditions shall be binding on the Creditors unless made in writing by an authorized officer of Hummingbird. No failure on the part of any Creditor to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder preclude the other or further exercise thereof or the exercise of any other right. 12. Rights Not Exhaustive: All rights, powers and remedies of the Creditors hereunder shall be in addition to all rights, powers and remedies given to the Creditors at law, in equity, under statute, by agreement or otherwise. All such rights, powers and remedies are cumulative and not alternative and shall not be exhausted by any exercise thereof against the Guarantor or by any number of successive actions until and unless all of the Liabilities have been paid and each of the Guarantor's obligations hereunder has been fully performed. This guarantee is in addition to and not in substitution for any security held at any time by any of the Creditors. 13. Severability: Any provision of this guarantee which is or is deemed to be void, prohibited or unenforceable in any jurisdiction shall be severed from this guarantee with respect to such jurisdiction, without in any way invalidating the remaining provisions of this guarantee and without affecting such provision in any other jurisdiction. 14. Delivery and Completeness of Guarantee: Upon this guarantee, bearing the signature of the Guarantor, coming into the possession of Hummingbird, the same shall be deemed to be finally executed and delivered by the Guarantor and shall not be subject to or affected by any promise or condition affecting or limiting the Guarantor's liability except as set forth herein, and no statement, representation, agreement or promise on the part of any officer, employee or agent of any Creditor, unless contained herein, forms any part of this guarantee or has induced the making of this guarantee or shall be deemed in any way to affect the Guarantor's liability hereunder. This guarantee and the Participation Documents constitute the entire agreement between the Creditors and the Guarantor with respect to the subject matter hereof and cancels and supersedes any prior understandings and agreements between them with respect thereto. 15. Financial Condition: The Guarantor is fully aware of the financial condition of each of the Debtors, has made all inquiries which the Guarantor feels are necessary and acknowledges that the Guarantor has received no information from any Creditor regarding any Debtor or its financial condition. 16.

[GRAPHIC] May 24, 2006 Board of Directors and Special Committee of the Board of Directors Hummingbird Ltd. 1 Sparks Avenue Toronto, Ontario, Canada M2H 2W1 Members of the Board of Directors and Special Committee of the Board of Directors: We understand that Hummingbird Ltd. (the "Company"), Symphony Technology II-A, L.P. ("Symphony"), Linden Management Corporation, a wholly owned subsidiary of Symphony ("Holdco"), and Linden Acquisition Ltd., an indirect wholly owned subsidiary of Symphony and wholly owned subsidiary of Holdco ("Acquisition Sub"), intend to enter into an arrangement agreement (the "Arrangement Agreement") pursuant to which, among other things, at the agreed upon effective time, (i) all common shares of the Company then outstanding will be transferred to Acquisition Sub by operation of law in exchange for the right to receive an amount in cash equal to $26.75 and (ii) immediately thereafter, Acquisition Sub and the Company will amalgamate and continue as a wholly-owned subsidiary of Holdco, all by way of plan of arrangement under the Canada Business Corporations Act. The terms and conditions of the proposed transaction are set forth in more detail in the Arrangement Agreement (the "Proposed Transaction"). We have been requested by the Board of Directors of the Company and the Special Committee of the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company's shareholders of the consideration to be offered to such shareholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Proposed Transaction. In arriving at our opinion, we reviewed and analyzed: (1) the Arrangement Agreement and the specific terms of the Proposed Transaction, (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including the Company's Annual Report on Form 40-F for the fiscal year ended September 30, 2005 and the Interim Reports on Form 6-K for the quarters ended December 31, 2005 and March 31, 2006, (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including projections of the future financial performance of the Company for fiscal year 2006 prepared by management of the Company, (4) a trading history of the Company's common shares from May 21, 2004 to May 23, 2006 and a comparison of that trading history with those of other companies that we deemed relevant, (5) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant, (6) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant, (7) published estimates of independent research analysts with respect to the Company's future financial performance, its ratings and price targets of its common shares, and (8) indications of interest from third parties with respect to the purchase of all or a portion of the Company or its business or assets, provided, that we were not requested by the Company to, and did not, actively solicit such indications of interest. In addition, we have had discussions with the management of the Company concerning its business, operations, assets, financial condition and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate. In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of the management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company, upon advice of the Company we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and that the Company will perform substantially in accordance with such projections. We have not been provided with, and did not have any access to, financial projections of the Company for any period following fiscal year 2006. Accordingly, in conjunction with the Company's other financial advisor, we prepared extensions to the financial projections of the Company through fiscal year 2011 on the basis of assumptions discussed with, and deemed reasonable by, the management of the Company and they have agreed to the use of, and our reliance upon, such extensions in performing our analysis. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the consideration to be offered in the Proposed Transaction to the shareholders of the Company is fair to such shareholders. We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services, a portion of which is payable upon delivery of this letter and the remainder which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for the Company in the past and have received customary fees for such services. Andrew Malik, a managing director of Lehman Brothers, is a member of the Board of Directors of the Company and, in accordance with Lehman Brothers' policy, has recused himself from voting on the Proposed Transaction. In the ordinary course of our business, we actively trade in the equity securities of the Company for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. This opinion is for the use and benefit of the Board of Directors of the Company and the Special Committee of the Board of Directors of the Company and is rendered to the Board of Directors and the Special Committee of the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any shareholder of the Company as to how such shareholder should vote with respect to the Proposed Transaction.

We further have assumed, with the consent of Hummingbird, that all third party consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on Hummingbird or the Transaction. We express no view or opinion as to any terms or aspects of the Transaction (other than the Consideration to the extent expressly specified herein), including, without limitation, the form or structure of the Transaction. As you are aware, we were not requested to, and we did not, solicit proposals from third parties regarding the acquisition of all or a portion of Hummingbird although we understand that, from time to time in the past, representatives of Hummingbird have held discussions with, and received indications of interest from, certain third parties with respect to a potential acquisition of Hummingbird. We also were not requested to, and we did not, assist the Board of Directors or the Special Committee of Hummingbird in their evaluation of alternatives for Hummingbird, including the decision of the Board of Directors of Hummingbird to proceed with exclusive negotiations with Symphony in respect of a Transaction, or in the negotiations of the terms of the Transaction, nor were we requested to, and we did not, provide any advice or services in connection with the Transaction other than the delivery of this opinion. We express no view or opinion as to any such matters and have assumed, with the consent of Hummingbird, that the terms of the Agreement and related Plan of Arrangement are, from the perspective of Hummingbird, the most beneficial terms that could be negotiated among the parties to the Agreement and related Plan of Arrangement and the transactions contemplated thereby. In addition, we express no view or opinion as to the relative merits of the Transaction in comparison to other transactions available to Hummingbird or in which Hummingbird might engage or as to whether any transaction might be more favorable to Hummingbird as an alternative to the Transaction, nor are we expressing any opinion as to the underlying business decision of the Board of Directors or the Special Committee of Hummingbird to proceed with or effect the Transaction. We have acted as financial advisor to Hummingbird solely to render this opinion and will receive a fee for our services payable upon rendering this opinion. In the ordinary course of our businesses, we and our affiliates may actively trade or hold securities of Hummingbird and certain affiliates of Symphony and may actively trade or hold loans of Hummingbird, Symphony and their respective affiliates for our own accounts or for the accounts of customers and, accordingly, we or our affiliates may at any time hold long or short positions in such securities or loans. It is understood that this letter is for the benefit and use of the Special Committee of the Board of Directors of Hummingbird in connection with and for purposes of its evaluation of the Transaction. In addition, we express no opinion or recommendation as to how the shareholders of Hummingbird should vote or act in connection with the Transaction.

May 24, 2006 Page 3 Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and we do not have any obligation to update, revise or reaffirm this opinion.

ARTICLE 3 RIGHTS OF DISSENT 3.1 Rights of Dissent (a) A Shareholder may exercise rights of dissent (the "Dissent Rights") pursuant to and in the manner set forth in section 190 of the CBCA and this section 3.1 in connection with the Arrangement; provided, however, that, notwithstanding subsection 190(5) of the CBCA, any written objections to the Arrangement Resolution must be received by Hummingbird not later than 5:00 p.m. (Toronto time) on the day which is two business days preceding the Meeting. A Shareholder who duly exercises such Dissent Rights and who: (i) is ultimately entitled to be paid fair value for its Hummingbird Shares shall be deemed to have transferred such Hummingbird Shares to Acquisition Sub on the Effective Date contemporaneously with the event described in Section 2.3(e) in exchange for the fair value of such Hummingbird Shares; or (ii) is ultimately not entitled, for any reason, to be paid fair value for its Hummingbird Shares shall be deemed to have participated in the Arrangement on the same basis as a non-dissenting Shareholder. (b) In no circumstances shall Parent, Acquisition Sub, Hummingbird or any other Person be required to recognize a Person exercising Dissent Rights unless such Person is a Shareholder of those Hummingbird Shares in respect of which such rights are sought to be exercised. (c) For greater certainty, in no case shall Parent, Acquisition Sub, Hummingbird or any other Person be required to recognize a Dissenting Holder as a Shareholder after the Effective Time, and the name of each Dissenting Holder shall be deleted from the register of Shareholders on the Effective Date at the same time as the events described in Section 2.3(e) occur. ARTICLE 4 CERTIFICATES AND PAYMENTS 4.1 Letter of Transmittal At the time of mailing the Circular or as soon as practicable thereafter, Hummingbird shall forward to each Shareholder and each Optionholder at the address of such holder as it appears on the register maintained by or on behalf of Hummingbird in respect of the holders of Hummingbird Shares or Hummingbird Options, as the case may be, a letter of transmittal in the case of the holders of Hummingbird Shares and, in the case of Optionholders, instructions for obtaining delivery of the consideration payable to Optionholders following the Effective Date pursuant to this Plan of Arrangement. 4.2 Exchange of Certificates for Cash (a) At or before the Effective Time, Acquisition Sub shall deposit the Maximum Cash Amount with the Depositary to be held in escrow until Section 2.3(a) takes effect. Upon surrender to the Depositary for cancellation of a certificate which immediately prior to the Effective Time represented outstanding Hummingbird Shares, together with a duly completed and executed Letter of Transmittal and such additional documents and instruments as the Depositary may reasonably require, the Shareholder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such Shareholder as soon as practicable after the Effective Time, a cheque representing the cash which such Shareholder has the right to receive under the Arrangement for such Hummingbird Shares, less any amounts withheld pursuant to Section 4.4, and any certificate so surrendered shall forthwith be cancelled. The cash deposited with the Depositary shall be held in an interest-bearing account, and any interest earned on such funds shall be for the account of Acquisition Sub. (b) Until surrendered as contemplated by this Section 4.2, each certificate which immediately prior to the Effective Time represented any Hummingbird Shares shall be deemed after the Effective Time to represent only the right to receive upon such surrender a cash payment in lieu of such certificate as contemplated in this Section 4.2, less any amounts withheld pursuant to Section 4.4. Any such certificate formerly representing Hummingbird Shares not duly surrendered on or before the sixth anniversary of the Effective Date shall cease to represent a claim by or interest of any former Shareholder of any kind or nature against or in Amalco, Hummingbird, Parent or Acquisition Sub. On such anniversary date, all certificates representing Hummingbird Shares shall be deemed to have been surrendered to Acquisition Sub and cash to which such former holder was entitled, together with any entitlements to dividends, distributions and interest thereon, shall be deemed to have been surrendered to Amalco. (c) On or as soon as practicable after the Effective Date, the Depositary shall deliver on behalf of Hummingbird to each Optionholder as reflected on the books and records of Hummingbird a cheque representing the payment to which such holder is entitled in accordance with Section 2.3(b) of this Plan of Arrangement, against receipt of such documentation as Parent or Hummingbird may reasonably require acknowledging the transfer and termination of the Hummingbird Options held by such Optionholder. (d) Any payment made by way of cheque by the Depositary on behalf of Acquisition Sub or Hummingbird that has not been deposited or has been returned to the Depositary or that otherwise remains unclaimed, in each case on or before the sixth anniversary of the Effective Date, shall cease to represent a right or claim of any kind or nature and the right of the Shareholder or Optionholder to receive the consideration for Hummingbird Shares or Hummingbird Options, as the case may be, pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Amalco for no consideration. 4.3 Lost Certificates In the event any certificate which immediately prior to the Effective Time represented one or more outstanding Hummingbird Shares that were transferred pursuant to Section 2.3 shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, cash deliverable in accordance with such holder's Letter of Transmittal. When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the Person to whom such cash is to be delivered shall as a condition precedent to the delivery of such cash, give a bond satisfactory to Amalco and the Depositary in such sum as Amalco may direct, or otherwise indemnify Amalco in a manner satisfactory to Amalco, against any claim that may be made against Acquisition Sub and Hummingbird with respect to the certificate alleged to have been lost, stolen or destroyed. 4.4 Withholding Rights Hummingbird, Acquisition Sub, Parent, Amalco and the Depositary and any affiliate of Hummingbird shall be entitled to deduct and withhold from any consideration otherwise payable to any Shareholder or Optionholder such amounts as Hummingbird, Acquisition Sub, Parent, Amalco or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the United States Internal Revenue Code of 1986 or any provision of federal, provincial, state, local or foreign tax law, in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the holder of the Hummingbird Shares or Hummingbird Options in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. ARTICLE 5 AMENDMENTS 5.1 Amendments to Plan of Arrangement (a) Hummingbird may amend, modify and/or supplement this Plan of Arrangement at any time and from time to time prior to the Effective Date, provided that each such amendment, modification and/or supplement must be (i) set out in writing, (ii) approved by Parent and Acquisition Sub, (iii) filed with the Court and, if made following the Meeting, approved by the Court, and (iv) communicated to Shareholders if and as required by the Court. (b) Any amendment, modification or supplement to this Plan of Arrangement may be proposed by Hummingbird at any time prior to the Meeting (provided that Parent and Acquisition Sub shall have consented thereto) with or without any other prior notice or communication, and if so proposed and accepted by the Persons voting at the Meeting (other than as may be required under the Interim Order), shall become part of this Plan of Arrangement for all purposes. (c) Any amendment, modification or supplement to this Plan of Arrangement that is approved or directed by the Court following the Meeting shall be effective only if (i) it is consented to by each of Hummingbird, Parent and Acquisition Sub (in each case, acting reasonably) and (ii) if required by the Court, it is consented to by Shareholders voting in the manner directed by the Court. (d) This Plan of Arrangement may be withdrawn prior to the occurrence of any of the events in Section 2.3 in accordance with the terms of the Arrangement Agreement. (e) Any amendment, modification or supplement to this Plan of Arrangement may be made following the Effective Date unilaterally by Parent, provided that it concerns a matter which, in the reasonable opinion of Parent, is of an administrative nature required to better give effect to the implementation of this Plan of Arrangement and is not adverse to the economic interest of any former Shareholder.

(1) Right to dissent -- Subject to sections 191 and 241, a holder of shares of any class of a corporation may dissent if the corporation is subject to an order under paragraph 192(4)(d) that affects the holder or if the corporation resolves to (a) amend its articles under section 173 or 174 to add, change or remove any provisions restricting or constraining the issue, transfer or ownership of shares of that class; (b) amend its articles under section 173 to add, change or remove any restriction on the business or businesses that the corporation may carry on; (c) amalgamate otherwise than under section 184; (d) be continued under section 188; (e) sell, lease or exchange all or substantially all its property under subsection 189(3); or (f) carry out a going-private transaction or a squeeze-out transaction. (2) Further right -- A holder of shares of any class or series of shares entitled to vote under section 176 may dissent if the corporation resolves to amend its articles in a manner described in that section. (2.1) If one class of shares -- The right to dissent described in subsection (2) applies even if there is only one class of shares. (3) Payment for shares -- In addition to any other right the shareholder may have, but subject to subsection (26), a shareholder who complies with this section is entitled, when the action approved by the resolution from which the shareholder dissents or an order made under subsection 192(4) becomes effective, to be paid by the corporation the fair value of the shares in respect of which the shareholder dissents, determined as of the close of business on the day before the resolution was adopted or the order was made. (4) No partial dissent -- A Dissenting Holder may only claim under this section with respect to all the shares of a class held on behalf of any one beneficial owner and registered in the name of the Dissenting Holder. (5) Objection -- A Dissenting Holder shall send to the corporation, at or before any meeting of shareholders at which a resolution referred to in subsection (1) or (2) is to be voted on, a written objection to the resolution, unless the corporation did not give notice to the shareholder of the purpose of the meeting and of their right to dissent. (6) Notice of resolution -- The corporation shall, within ten days after the shareholders adopt the resolution, send to each shareholder who has filed the objection referred to in subsection (5) notice that the resolution has been adopted, but such notice is not required to be sent to any shareholder who voted for the resolution or who has withdrawn their objection. (7) Demand for payment -- A Dissenting Holder shall, within twenty days after receiving a notice under subsection (6) or, if the shareholder does not receive such notice, within twenty days after learning that the resolution has been adopted, send to the corporation a written notice containing (a) the shareholder's name and address; (b) the number and class of shares in respect of which the shareholder dissents; and (c) a demand for payment of the fair value of such shares. (8) Common Share certificate -- A Dissenting Holder shall, within thirty days after sending a notice under subsection (7), send the certificates representing the shares in respect of which the shareholder dissents to the corporation or its transfer agent.

(11) Suspension of rights -- On sending a notice under subsection (7), a Dissenting Holder ceases to have any rights as a shareholder other than to be paid the fair value of their shares as determined under this section except where (a) the shareholder withdraws that notice before the corporation makes an offer under subsection (12), (b) the corporation fails to make an offer in accordance with subsection (12) and the shareholder withdraws the notice, or (c) the directors revoke a resolution to amend the articles under subsection 173(2) or 174(5), terminate an amalgamation agreement under subsection 183(6) or an application for continuance under subsection 188(6), or abandon a sale, lease or exchange under subsection 189(9), in which case the shareholder's rights are reinstated as of the date the notice was sent. (12) Offer to pay -- A corporation shall, not later than seven days after the later of the day on which the action approved by the resolution is effective or the day the corporation received the notice referred to in subsection (7), send to each Dissenting Holder who has sent such notice (a) a written offer to pay for their shares in an amount considered by the directors of the corporation to be the fair value, accompanied by a statement showing how the fair value was determined; or (b) if subsection (26) applies, a notification that it is unable lawfully to pay Dissenting Holders for their shares. (13) Same terms -- Every offer made under subsection (12) for shares of the same class or series shall be on the same terms. (14) Payment -- Subject to subsection (26), a corporation shall pay for the shares of a Dissenting Holder within ten days after an offer made under subsection (12) has been accepted, but any such offer lapses if the corporation does not receive an acceptance thereof within thirty days after the offer has been made. (15) Corporation may apply to court -- Where a corporation fails to make an offer under subsection (12), or if a Dissenting Holder fails to accept an offer, the corporation may, within fifty days after the action approved by the resolution is effective or within such further period as a court may allow, apply to a court to fix a fair value for the shares of any Dissenting Holder. (16) Shareholder application to court -- If a corporation fails to apply to a court under subsection (15), a Dissenting Holder may apply to a court for the same purpose within a further period of twenty days or within such further period as a court may allow. (17) Venue -- An application under subsection (15) or (16) shall be made to a court having jurisdiction in the place where the corporation has its registered office or in the province where the Dissenting Holder resides if the corporation carries on business in that province.

(20) Powers of court -- On an application to a court under subsection (15) or (16), the court may determine whether any other person is a Dissenting Holder who should be joined as a party, and the court shall then fix a fair value for the shares of all Dissenting Holders. (21) Appraisers -- A court may in its discretion appoint one or more appraisers to assist the court to fix a fair value for the shares of the Dissenting Holders. (22) Final order -- The final order of a court shall be rendered against the corporation in favour of each Dissenting Holder and for the amount of his shares as fixed by the court. (23) Interest -- A court may in its discretion allow a reasonable rate of interest on the amount payable to each Dissenting Holder from the date the action approved by the resolution is effective until the date of payment. (24) Notice that subsection (26) applies -- If subsection (26) applies, the corporation shall, within ten days after the pronouncement of an order under subsection (22), notify each Dissenting Holder that it is unable lawfully to pay Dissenting Holders for their shares. (25) Effect where subsection (26) applies -- If subsection (26) applies, a Dissenting Holder, by written notice delivered to the corporation within thirty days after receiving a notice under subsection (24), may (a) withdraw their notice of dissent, in which case the corporation is deemed to consent to the withdrawal and the shareholder is reinstated to their full rights as a shareholder, or (b) retain a status as a claimant against the corporation, to be paid as soon as the corporation is lawfully able to do so or, in a liquidation, to be ranked subordinate to the rights of creditors of the corporation but in priority to its shareholders. (26) Limitation -- A corporation shall not make a payment to a Dissenting Holder under this section if there are reasonable grounds for believing that (a) the corporation is or would after the payment be unable to pay its liabilities as they become due; or (b) the realizable value of the corporation's assets would thereby be less than the aggregate of its liabilities.

Signature Date 2006 INSTRUCTIONS 1. Use of Letter of Transmittal (a) In order to permit the timely receipt of the cash proceeds, it is recommended that this Letter of Transmittal (or manually signed facsimile thereof) together with accompanying certificate(s) representing Common Shares be received by the Depositary at the office specified below before 5:00 p.m. (Toronto time) on July 19, 2006, or in the case of any adjournment or postponement of the Meeting, no later than 5:00 p.m. (Toronto time) on the business day before the day that any adjourned or postponed Meeting is reconvened or held, as the case may be. Do not send the certificates or this Letter of Transmittal to Hummingbird or Acquisition Sub. (b) The method used to deliver this Letter of Transmittal and any accompanying certificates representing Common Shares is at the option and risk of the holder surrendering them, and delivery will be deemed effective only when such documents are actually received. Hummingbird recommends that the necessary documentation be hand delivered to the Depositary at the address specified below, and a receipt obtained therefor; otherwise the use of registered mail with return receipt requested, and with proper insurance obtained, is recommended. Shareholders whose Common Shares are registered in the name of a broker, investment dealer, bank, trust company or other nominee should contact that nominee for assistance in delivering those Common Shares. 2. Signatures This Letter of Transmittal must be completed, dated and signed by the holder of Common Shares or by such holder's duly authorized representative (in accordance with Instruction 4).

(c) If any of the surrendered Common Shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of Common Shares. 3. Guarantee of Signatures No signature guarantee is required on this Letter of Transmittal if this Letter of Transmittal is signed by the registered holder(s) of Common Shares surrendered herewith.

Medallion Signature Program (MSP). 4.

Miscellaneous (a) If the space on this Letter of Transmittal is insufficient to list all certificates for Common Shares, additional certificate numbers and numbers of shares may be included on a separate signed list affixed to this Letter of Transmittal. (b) If Common Shares are registered in different forms (e.g. "John Doe" and "J. Doe"), a separate Letter of Transmittal should be signed for each different registration.

The Depositary and/or the registrar and transfer agent for the Common Shares will respond with the replacement requirements in order for you to receive your entitlement, which shall include a requirement to provide an affidavit and such other requirements as the Depositary may determine in its sole discretion, including a bond and indemnification against any claim that may be made against Acquisition Sub with respect to the certificate alleged to have been lost, stolen or destroyed. 8. Return of Certificates If the Arrangement does not proceed for any reason, any certificate(s) for Common Shares received by the Depositary will be returned to you forthwith in accordance with your delivery instructions in Box "D". 9. United States Holders and Substitute Form W-9 United States federal income tax law generally requires that a United States Holder (as defined below) who receives cash in exchange for Common Shares provide the Depositary with his correct Taxpayer Identification Number ("TIN") which, in the case of a holder of Common 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, as the case may be, 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 by the holder from the Internal Revenue Service. To prevent backup withholding, each United States Holder must provide his correct TIN by completing the Substitute Form W-9 set out in this document, which requires such holder to certify under penalty 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 backup withholding; (ii) the holder has not been notified by the Internal Revenue Service that he is subject to backup withholding as a result of a failure to report all interest or dividends; or (iii) the Internal Revenue Service has notified the holder that he is no longer subject to backup withholding; and (3) that the holder is a U.S. person (including a U.S. resident alien). Certain holders (including, among others, all corporations) are exempt recipients not subject to these backup withholding requirements. To prevent possible erroneous backup withholding, an exempt holder must enter its correct TIN in Part 1 or Substitute Form W-9, write "Exempt" in Part 2 of such form, and sign and date the form. See the "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" (the "W-9 Guidelines") that follow these instructions. If Common Shares are held in more than one name or are not in the name of the actual owner, consult the W-9 Guidelines for information on which TIN to report. If a United States Holder does not have a TIN, such holder should: (i) consult the W-9 Guidelines for instructions on applying for a TIN; (ii) write "Applied For" in the space for the TIN in Part I 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 out 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 United States Holder 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 of perjury. An appropriate IRS Form W-8 (W-8BEN, W-8EXP or other form) may be obtained from the Depositary. For purposes of these instructions, a "United States Holder" is (i) a citizen or individual resident of the United States, (ii) a corporation (including an entity taxable as a corporation) or partnership created under the laws of the United States or any political subdivision thereof, (iii) an estate the income of which is subject to United States federal income tax regardless of its source or (iv) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (b) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person. A UNITED STATES HOLDER WHO FAILS TO PROPERLY COMPLETE THE SUBSTITUTE FORM W-9 SET OUT IN THIS LETTER OF 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 ARRANGEMENT. BACKUP WITHHOLDING IS NOT AN ADDITIONAL TAX. RATHER, THE TAX LIABILITY OF PERSONS SUBJECT TO BACKUP WITHHOLDING WILL BE REDUCED BY THE AMOUNT OF TAX WITHHELD. IF WITHHOLDING RESULTS IN AN OVERPAYMENT OF TAXES, A REFUND MAY BE OBTAINED BY FILING A TAX RETURN WITH THE IRS. THE DEPOSITARY CANNOT REFUND AMOUNTS WITHHELD BY REASON OF BACKUP WITHHOLDING. TO ENSURE COMPLIANCE WITH TREASURY DEPARTMENT CIRCULAR 230, SHAREHOLDERS ARE HEREBY NOTIFIED THAT: (A) ANY DISCUSSION OF U.S. FEDERAL TAX ISSUES IN THIS LETTER OF TRANSMITTAL IS NOT INTENDED OR WRITTEN TO BE RELIED UPON, AND CANNOT BE RELIED UPON, BY SUCH SHAREHOLDERS FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED ON SUCH SHAREHOLDERS UNDER THE INTERNAL REVENUE CODE; (B) SUCH DISCUSSION IS BEING USED IN CONNECTION WITH THE PROMOTION OR MARKETING (WITHIN THE MEANING OF CIRCULAR 230) OF THE TRANSACTIONS OR MATTERS ADDRESSED HEREIN; AND (C) EACH SHAREHOLDER SHOULD SEEK ADVICE BASED ON ITS PARTICULAR CIRCUMSTANCES FROM AN INDEPENDENT TAX ADVISOR. FOR UNITED STATES HOLDERS ONLY GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 Guidelines for Determining the Proper Identification Number for the Payee (You) To Give the Depositary -- Social security numbers have nine digits separated by two hyphens: i.e., 000-00-0000. Employee identification numbers have nine digits separated by only one hyphen: i.e., 00-0000000. The table below will help determine the number to give the Depositary. All "Section" references are to the Internal Revenue Code of 1986, as amended. "IRS" is the Internal Revenue Service. PRIVATE For This Type of Account: Give The Taxpayer Identification

OBTAINING A NUMBER If you don't have a taxpayer identification number or you don't know your number, obtain Form SS-5, Application for a Social Security Card, or Form SS-4, Application for Employer Identification Number, at an office of the Social Security Administration or the Internal Revenue Service and apply for a number. PAYEES EXEMPT FROM BACKUP WITHHOLDING Payees specifically exempted from backup withholding include: (i) An organization exempt from tax under Section 501(a), an individual retirement account (IRA), or a custodial account under Section 403(b)(7), if the account satisfies the requirements of Section 401(f)(2).

(ii) Payments to partnerships not engaged in a trade or business in the United States and that have at least one non-resident partner. (iii) Payments of patronage dividends not paid in money. (iv) Payments made by certain foreign organizations. (v) Section 404(k) payments made by an ESOP. Payments of interest generally exempt from backup withholding include: (i) Payments of interest on obligations issued by individuals.

(ii) Payments of tax-exempt interest (including exempt-interest dividends under Section 852). (iii) Payments described in Section 6049(b)(5) to non-resident aliens.

For details, see the regulations under sections 6041. 6041A, 6042, 6044, 6045, 6049, 6050A and 6050N. Exempt payees described above must file a Substitute Form W-9 included in this Letter of Transmittal to avoid possible erroneous backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" IN PART 2 OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER. PRIVACY ACT NOTICE -- Section 6109 requires you to provide your correct taxpayer identification number to payers, who must report the payments to the IRS. The IRS uses the number for identification purposes and may also provide this information to various government agencies for tax enforcement or litigation purposes. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to payer. Certain penalties may also apply. PENALTIES (1) Failure to Furnish Taxpayer Identification Number -- If you fail to furnish your taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to wilful neglect. (2) Civil Penalty for False Information With Respect to Withholding -- If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty. (3) Criminal Penalty for Falsifying Information -- Wilfully falsifying certificates or affirmations may subject you to criminal penalties including fines and/or imprisonment.
