This Letter of Transmittal and Election Form, and the Election you make herein, are subject to terms and conditions set forth herein, in the Proxy Circular which was sent to you shortly prior to this Letter of Transmittal and Election Form and in the Acquisition Agreement and the Amalgamation Agreement, which are appended as Appendixes A and B thereto, respectively. EACH HOLDER OF DISCREET COMMON SHARES IS STRONGLY ENCOURAGED TO READ THE PROXY CIRCULAR IN ITS ENTIRETY AND TO DISCUSS THE CONTENTS THEREOF AND THIS LETTER OF TRANSMITTAL AND ELECTION FORM WITH HIS OR HER FINANCIAL AND TAX ADVISORS PRIOR TO MAKING THE ELECTION. A. ELECTIONS Each holder of Discreet Common Shares will receive upon the Amalgamation one New Discreet Class B Share for each Discreet Common Share then held by such holder. Immediately following the Amalgamation, each such New Discreet Class B Share will automatically, based upon whether the holder thereof has made a valid Election to receive New Discreet Exchangeable Shares pursuant to this Letter of Transmittal and Election Form, either (i) be redeemed by New Discreet for 0.33 New Discreet Exchangeable Shares (subject to proration as contemplated in Instruction B) or (ii) be converted into one New Discreet Unit, which will immediately thereafter be acquired by Dutchco in exchange for 0.33 shares of Autodesk Common Stock, in either case without any further required action on the part of the holder. A Discreet Shareholder's failure to complete the election form in Box B or to return a completed Letter of Transmittal and Election Form with all accompanying documents prior to the Election Deadline will automatically result in such holder receiving Autodesk Common Stock if the Transactions are completed. B. PRORATION Pursuant to the Acquisition Agreement, the maximum number of New Discreet Exchangeable Shares that may be issued in the Transactions cannot exceed 19.99% of the Discreet Common Shares outstanding immediately prior to the Amalgamation, multiplied by 0.33 (the "Maximum Number"). In the event that the aggregate number of New Discreet Exchangeable Shares requested by Discreet Shareholders pursuant to valid Letters of Transmittal and Election Forms (the "Aggregate Elected Amount") exceeds the Maximum Number, each holder making an effective Election will receive, for each New Discreet Class B Share for which such Election is made, (x) from New Discreet, a number of New Discreet Exchangeable Shares equal to the product of 0.33 and a fraction, the numerator of which is the Maximum Number and the denominator of which is the Aggregate Elected Amount (such product, the "Prorated Amount"), and (y) from Dutchco, a number of shares of Autodesk Common Stock equal to 0.33 minus the Prorated Amount. C. DELIVERY OF DISCREET COMMON SHARES BY BOOK-ENTRY TRANSFER. The Depositary will establish an account with respect to the Discreet Common Shares at The Depositary Trust Company or the Philadephia Depositary Trust Company (each, a "Book Entry Transfer Facility") for purposes of the Transactions within two business days after the date the Proxy Circular is mailed to Discreet Shareholders. Any financial institution that is a participant in the Book Entry Transfer Facility's systems may make book entry delivery of Discreet Common Shares by causing the Book Entry Transfer Facility to transfer such Discreet Common Shares into the Depositary's account in accordance with the Book Entry Transfer Facility's procedure for such transfer. However, although delivery of Discreet Common Shares may be effected through book entry transfer into the Depositary's account at the Book Entry Transfer Facility, the Letter of 6 Transmittal and Election Form, properly completed and duly executed, with any required signature guarantees, or an Agent's Message (as defined below), and any other required documents must, in any case, be transmitted to, and received by, the Depositary prior to the Election Deadline. The confirmation of book entry transfer of Discreet Common Shares into the Depositary's account at the Book Entry Transfer Facility as described above is referred to herein as a "Book Entry Confirmation." Delivery of documents to the Book Entry Transfer Facility does not constitute delivery to the Depositary. The term "Agent's Message" means a message transmitted by the Book Entry Transfer Facility to, and received by, the Depositary and forming a part of the Book Entry Confirmation, which states that such Book Entry Transfer Facility has received an express acknowledgment from the participant in such Book Entry Transfer Facility tendering the Discreet Common Shares that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and Election Form and that Autodesk may enforce such agreement against the participant. D. SPECIAL CONDITIONS. 1. Revocation. You may revoke any Election or revoke any instruction in this Letter of Transmittal and Election Form only by written notice, signed and dated by you, to the Depositary. Such written notice must identify the name of the holder of record of the Discreet Common Shares subject to such revocation and the serial number shown on the Certificate(s) representing such shares. The written notice must be received by the Depositary prior to the Election Deadline. If an Election is revoked or any other instruction in your Letter of Transmittal and Election Form is revoked prior to the Election Deadline, the Certificate(s) for your Discreet Common Shares shall be promptly returned to you. A subsequently dated, properly completed Letter of Transmittal and Election Form relating to Discreet Common Shares for which a valid Letter of Transmittal and Election Form and Certificate(s) has previously been received by the Depositary will serve as both a revocation of the first Letter of Transmittal and Election Form and a new Election. If you revoke your Election and you fail to properly make a new Election prior to the Election Deadline, you will receive shares of Autodesk Common Stock upon consummation of the Transactions. 2. Shares Held by Nominees, Trustees or other Representatives. Holders of record of Discreet Common Shares who hold such shares as nominees, trustees or in other representative or fiduciary capacities (each, a "Representative") may submit one or more Letters of Transmittal and Election Forms covering the aggregate number of Discreet Common Shares held by such Representative for the beneficial owners for whom the Representative is making an Election, provided that such Representative certifies that each such Letter of Transmittal and Election Form covers all of the Discreet Common Shares held by such Representative for a particular beneficial owner. Any Representative who makes an Election may be required to provide the Depositary with such documents and/or additional certifications, if requested, in order to satisfy the Depositary that such Representative holds such Discreet Common Shares for a particular beneficial owner of such shares. E. NO FRACTIONAL SHARES. No fractional shares of New Discreet Exchangeable Shares or Autodesk Common Stock will be issued. In lieu of the issuance of any fractional shares pursuant to the Transactions, a cash adjustment will be paid in respect of any fractional share that would otherwise be issuable. The amount of such cash adjustment will be the product of such fractional amount (after aggregating all fractional shares to which a holder is entitled) and the average of the closing prices of the Autodesk Common Stock on the Nasdaq National Market for each of the thirty consecutive trading days immediately preceding the Effective Time. 7 F. GENERAL INSTRUCTIONS. 1. Execution and Delivery This Letter of Transmittal and Election Form, or a photocopy of it, should be properly completed, dated and signed, and should be delivered, together with your stock Certificate(s) representing Discreet Common Shares to the Depositary at the appropriate address set forth in this Letter of Transmittal and Election Form. YOU MAY CHOOSE ANY METHOD TO DELIVER THIS LETTER OF TRANSMITTAL AND ELECTION FORM AND ACCOMPANYING CERTIFICATES TO THE DEPOSITARY (INCLUDING BY BOOK ENTRY TRANSFER); HOWEVER, YOU ASSUME ALL RISK OF NON- DELIVERY. IF YOU CHOOSE TO USE THE MAIL, WE STRONGLY RECOMMEND THAT YOU USE REGISTERED MAIL, RETURN RECEIPT REQUESTED, AND THAT YOU PROPERLY INSURE ALL STOCK CERTIFICATES. DELIVERY OF THIS LETTER OF TRANSMITTAL AND ELECTION FORM AND ACCOMPANYING STOCK CERTIFICATES WILL BE DEEMED EFFECTIVE AND RISK OF LOSS WITH RESPECT TO SUCH LETTER OF TRANSMITTAL AND ACCOMPANYING CERTIFICATES WILL PASS ONLY WHEN SUCH LETTER OF TRANSMITTAL AND ELECTION FORM AND ACCOMPANYING CERTIFICATES ARE ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK ENTRY TRANSFER, BY BOOK ENTRY CONFIRMATION). 2. Signatures The signature (or signatures, in case the of Certificate(s) owned by two or more joint holders) on this Letter of Transmittal and Election Form must correspond exactly to the name as written on the face of the Certificate(s) sent to the Depositary, unless the Discreet Common Shares have been transferred by the holder of record. If there has been any such transfer, the signatures on this Letter of Transmittal and Election Form should be signed in exactly the same form as the name of the last transferee indicated on the accompanying stock powers attached to or endorsed on the Certificate(s) (see General Instruction 4 below). If there is insufficient space to list all or your Certificates being submitted to the Depositary or to respond to any other request for information, please attach a separate sheet. If Discreet Common Shares are registered in different names on several Certificates, it will be necessary to complete, sign and submit a separate Letter of Transmittal and Election Form for each different registration of Certificates. For example, if some Certificates are registered solely in your name, some are registered solely in your spouse's name and some are registered jointly in the name of you and your spouse, three separate Letters of Transmittal and Election Forms should be submitted. 3. Checks and/or Certificates in Same Name If checks in payment of any fractional share interests and/or any new stock certificates (representing either New Discreet Exchangeable Shares or Autodesk Common Stock, as applicable) are to be payable to the order of and/or registered in exactly the same name as inscribed on the surrendered Certificate(s) (representing Discreet Common Shares), you will not be required to endorse the old Certificates or make payment for transfer taxes or have your signature guaranteed. For corrections in name or changes in name not involving changes in ownership, see General Instruction 4(d). 4. Checks and/or Certificates in Different Names. (IGNORE THIS INSTRUCTION 4 IF THE FIRST SENTENCE OF INSTRUCTION 3 APPLIES.) 8 If checks in payment of Fractional Shares and/or any new stock certificates (representing either New Discreet Exchangeable Shares or Autodesk Common Stock, as applicable) are to be payable to the order of and/or registered in a different name from exactly the registered name inscribed on the surrendered Certificate(s) (representing Discreet Common Shares), please follow these instructions: (a) Endorsement and Guaranteee. The Certificate(s) surrendered must be properly endorsed or accompanied by appropriate stock power(s) properly executed by the record holder of such Certificate(s) to the person who is to receive the check or certificate representing either New Discreet Exchangeable Shares or Autodesk Common Stock, as applicable. The signature of the record holder on the endorsement(s) or stock power(s) must correspond with the name that appears on the face of the Certificate(s) in every particular and must be guaranteed by an Eligible Institution. If this General Instruction 4 applies, please check with your financial institution or brokerage firm immediately to determine whether it is an Eligible Institution or will need to help you locate an Eligible Institution. An "Eligible Institution" generally means a Canadian chartered bank, a major trust company in Canada, a member of a recognized stock exchange in Canada, a commercial bank or trust company having an office, branch or agency in the United States of America, a member of the Investment Dealers Association of Canada, a member of a national securities exchange in the United States of America, a member of the National Association of Securities Dealers, Inc. or a member firm of a recognized Medallion Program ((STAMP), (SEMP) or (MSP)). Notaries Public cannot execute acceptable guarantees of signatures. (b) Transferee's Signature. If a certificate has previously been properly transferred but the transfer has not yet been recorded on the books of Discreet, this Letter of Transmittal and Election Form must be signed by the transferee or by his agent and should not be signed by the transferor. The signature of such transferee or agent on this Letter of Transmittal and Election Form must be guaranteed by an Eligible Institution. (c) Transfer Taxes. In the event that any transfer or other tax becomes payable by reason of the issuance of a check in payment of any fractional shares and/or the issuance of any stock certificates for either New Discreet Exchangeable Shares or Autodesk Common Stock, as applicable, in any name other than that of the record holder, the transferee or assignee must pay such tax to the Depositary or must establish to the satisfaction of the Depositary that such tax has been paid. You should consult your own tax advisor as to any possible tax consequences resulting from the issuance of stock or cash in a name different from that of the holder of record of the surrendered Certificate. (d) Correction of or Change in Name. For a correction in name which does not involve a change in ownership, the surrendered Certificate(s) should be appropriately endorsed; for example, "James E. Brown, incorrectly inscribed as James S. Brown," with the signature guaranteed by an Eligible Institution. For a change in name by marriage, etc., the surrendered Certificate(s) should be appropriately endorsed; for example, "Mary Doe, now by marriage Mrs. Mary Jones," with the signature guaranteed by an Eligible Institution. 5. Supporting Evidence. Where this Letter of Transmittal and Election Form is executed by a person as an executor, administrator, trustee or guardian, or on behalf of a corporation, partnership or association or is executed by any other person acting in a representative capacity, this Letter of Transmittal and Election Form must be accompanied by satisfactory evidence of authority to act. Any of Discreet, New Discreet, Autodesk or the Depositary, in their discretion, may require additional evidence of authority or additional documentation. 6. Notice of Defects; Resolution of Disputes. None of Autodesk, Dutchco, Discreet, New Discreet and the Depositary will be under any obligation to notify you or anyone else that the Depositary has not received a properly completed Letter of Transmittal and Election Form or that any Letter of Transmittal and Election Form submitted is defective in any way. 9 Any and all disputes with respect to Letters of Transmittal and Elections made in respect of Discreet Common Shares (including but not limited to matters relating to the Election Deadline, time limits, defects or irregularities in the surrender of any Certificate, effectiveness of any Election and computations or prorations or allocations) will be resolved by Autodesk and its decision will be conclusive and binding on all parties concerned. Autodesk will have the absolute right in its sole discretion to reject any and all Letters of Transmittal and Election Forms and surrenders of Certificates which are deemed by it to be not in proper form or to waive any immaterial irregularities in any Letter of Transmittal and Election Form or in the surrender of any Certificate. Surrenders of Certificates will not be deemed to have been made until all defects or irregularities that have not been waived have been cured. 7. US Federal Tax Withholding. Under US federal income tax law, the Depositary is required to file a report with the Internal Revenue Service ("IRS") disclosing the payments being made to you as an exchanging shareholder. Federal law also requires each shareholder to provide the Depositary with a correct Taxpayer Identification Number ("TIN") on a Substitute Form W-9 enclosed with the Letter of Transmittal and Election Form. If the Depositary is not provided with the correct TIN, you may be subject to a $50 penalty by the IRS and payments that are made to you with respect to surrendered shares may be subject to backup withholding. For individuals, your TIN is your social security number. Your TIN should be included in Part 3 of the Substitute W-9 form provided with the Letter of Transmittal and Election Form. Certain shareholders (such as foreign persons) are not subject to back-up withholding and reporting requirements. If you are exempt from backup withholding, you should complete the Substitute W-9 to avoid possible erroneous backup withholding. Enter your correct TIN in Part 3, write "EXEMPT" in the block in Part 2 of the Substitute W-9, and sign and date the form. A foreign person may qualify as an exempt recipient by submitting to the Depositary a Form W-8 in lieu of the Substitute Form W-9, signed under penalties of perjury, attesting to that individual's exempt status. A Form W-8 is included with this Letter of Transmittal and Election Form. If backup withholding applies, the Depositary is required to withhold 31% of any payments to be made to you. Backup withholding is not an additional tax. Rather, the amount of tax withheld will be applied as a credit against the tax liability of persons subject to backup withholding. 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 complete the form if you do not have a TIN, write "Applied for" in the space for the TIN in Part 3 and sign and date the form. If the Depositary does not receive your TIN by the time of payment, backup withholding may apply. You must also complete the Certificate of Awaiting Taxpayer Identification Number. To apply for a TIN, get Form SS-5, Application for a Social Security Card (for individuals), from your local office of the Social Security Administration, or Form SS-4, Application for Employer Identification Number (for businesses and all other entities), from your local IRS office. 8. Special Mailing Instructions. Any checks representing fractional share payments and certificates representing stock consideration for surrendered Discreet Common Shares will be mailed to the address of the holder of record as indicated in Box A (Certificates Surrendered), unless instructions to the contrary are given in Box D (Special Delivery Instructions). 9. Lost Stock Certificates. If you are unable to locate the Certificate(s) representing your Discreet Common Shares, contact the Depositary at (800) 313-7416. The Depositary will instruct you on the procedures to follow. In order to make an 10 effective Election with respect to the lost Certificate(s) and receive the consideration provided for in the Acquisition Agreement, you will be required to complete certain additional documentation and pay for an indemnity bond covering the lost Certificate(s). The cost of this bond will be based on the value of the Discreet Common Shares represented by the lost Certificates. IF YOU HAVE NOT COMPLETED THE LETTER OF TRANSMITTAL AND ELECTION FORM, COMPLIED WITH THE PROCEDURES FOR REPLACING LOST CERTIFICATES AND PAID FOR THE INDEMNITY BOND PRIOR TO THE ELECTION DEADLINE, YOU WILL BE DEEMED TO HAVE MADE AN ELECTION TO RECEIVE AUTODESK COMMON STOCK WITH RESPECT TO DISCREET COMMON SHARES REPRESENTED BY THE LOST CERTIFICATE. 10. Miscellaneous. As soon as practicable after the Election Deadline, the Depositary will begin mailing and delivering stock certificates for New Discreet Exchangeable Shares and/or Autodesk Common Stock in exchange for Certificates representing Discreet Common Shares that have been received by the Depositary. There will be a delay, however, if backup withholding pursuant to General Instruction 7 applies. 11 Additional copies of the Letter of Transmittal may be obtained from the Depositary.
