This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed or stolen certificates have been followed. 12. WARRANTS. If a tender of shares of Multex Common Stock is being made by delivery of Warrants, the tendering holder of Warrants thereby makes all the representations, warranties and agreements about the Warrants that a holder of shares of Multex Common Stock makes about the shares of Multex Common 12 Stock. Each such tendering holder of Warrants also irrevocably agrees to exercise such Warrants and authorizes and directs the Depositary to pay to Multex on behalf of the tendering holder of Warrants an amount equal to the exercise price per share of Multex Common Stock represented by any Warrant tendered against delivery by Multex to the Depositary of the shares of Multex Common Stock issuable upon exercise of the Warrant registered in the name of Purchaser and to deduct such amount from the amount otherwise payable in respect of the shares of Multex Common Stock issuable upon exercise of the Warrant. Like holders of shares of Multex Common Stock who tender pursuant to procedures for guaranteed delivery, tendering holders of Warrants shall not be entitled to receive payment for shares of Multex Common Stock until Multex delivers to the Depositary such shares of Multex Common Stock registered in the name of Purchaser. The procedures described below are the only means to tender shares of Multex Common Stock through the delivery of Warrants. To tender Shares of Multex Common Stock through the delivery of certificates representing Warrants pursuant to the Offer, a holder of Warrants must submit (a) a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile thereof), together with any other required signature guarantees and any other required documents, (b) certificates for the Warrants and (c) a completed Subscription Form (in the form attached to each Warrant as Exhibit A) for each Warrant, executed by the holder of such Warrant and directing that shares of Multex Common Stock issued on exercise be registered in the name of Purchaser, must all be received by the Depositary at one of its addresses set forth herein prior to the Expiration Date. Holders of Warrants who wish to tender shares of Multex Common Stock pursuant to the procedures for book-entry transfer or guaranteed delivery procedures must first exercise their Warrants for shares of Multex Common Stock. IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE THEREOF (TOGETHER WITH THE APPLICABLE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR THE NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE. IMPORTANT TAX INFORMATION Under the U.S. federal income tax law, a stockholder whose tendered shares of Multex Common Stock (including through the delivery of Warrants) are accepted for purchase is required by law to provide the Depositary (as payer) with such stockholder's correct TIN on Substitute Form W-9 below and to certify that such TIN is correct (or that such stockholder is awaiting a TIN) or otherwise establish a basis for exemption from backup withholding. If such stockholder is an individual, the TIN is generally his or her U.S. social security number. If a stockholder fails to provide a TIN to the Depositary, such stockholder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, payments that are made to such stockholder with respect to shares of Multex Common Stock purchased pursuant to the Offer may be subject to backup withholding at 30% (see below). Certain stockholders (including, among others, all corporations and certain foreign individuals and entities) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, that stockholder must generally submit a Form W-8, signed under penalties of perjury, attesting to that individual's exempt status. A Form W-8 can be obtained from the Depositary. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional instructions. If backup withholding applies, the Depositary is required to withhold 30% of any payments made to the stockholder or payee pursuant to the Offer. 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 from the Internal Revenue Service provided certain conditions are met. 13 PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup withholding on payments made to a stockholder whose tendered shares of Multex Common Stock (including through the delivery of Warrants) are accepted for purchase, the stockholder is required to notify the Depositary of its correct TIN by completing Substitute Form W-9 certifying (1) that the TIN provided on such Form is correct (or that such stockholder is awaiting a TIN, in which case the stockholder should check the box in Part 3 of the Substitute Form W-9), (2) that such stockholder is a U.S. person and (3) that (A) such stockholder is exempt from backup withholding, (B) such stockholder has not been notified by the Internal Revenue Service that such stockholder is subject to backup withholding as a result of failure to report all interest or dividends or (C) the Internal Revenue Service has notified the stockholder that the stockholder is no longer subject to backup withholding. The stockholder must sign and date the Substitute Form W-9 where indicated, certifying, under penalties of perjury, that the information on such Form is correct. A nonexempt stockholder may check the box in Part 3 of the attached Substitute Form W-9 if such stockholder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If a nonexempt stockholder checks the box in Part 3, such stockholder must also sign the attached Certification of Awaiting Taxpayer Identification Number in order to prevent backup withholding. Notwithstanding that a stockholder complies with the foregoing, the Depositary will backup withhold at 30% on payments made to such stockholder pursuant to the Offer prior to the time a properly certified TIN is provided to the Depositary. Alternatively, a stockholder that qualifies as an exempt recipient (other than a shareholder required to complete Form W-8 as described above) should write "Exempt" in Part 1 of the Substitute Form W-9, enter his correct TIN and sign and date such Form where indicated. 14 TO BE COMPLETED BY ALL TENDERING STOCKHOLDERS (SEE INSTRUCTION 9) PAYOR: AMERICAN STOCK TRANSFER & TRUST COMPANY <Table> <Caption> - --------------------------------------------------------------------------------------------------------- - --------------------------------------------------------------------------------------------------------- SUBSTITUTE PART 1 -- PLEASE PROVIDE YOUR TIN IN THE BOX Social security number OR FORM W-9 AT RIGHT AND CERTIFY BY SIGNING AND DATING Employer Identification Number BELOW. --------------------------------- --------------------------------------------------------------------------------- </Table> <Table> <Caption> DEPARTMENT OF THE PART 2 -- CERTIFICATION -- UNDER PENALTIES OF PERJURY, I CERTIFY THAT: TREASURY (1) The number shown on this form is my correct taxpayer identification number INTERNAL REVENUE (or I am waiting for a number to be issued to me); SERVICE (2) I am not subject to backup withholding because (i) I am exempt from backup withholding, (ii) I have not been notified by the Internal Revenue Service PAYOR'S REQUEST FOR (the "IRS") that I am subject to backup withholding as a result of a failure TAXPAYER to report all interest and dividend income or (iii) the IRS has notified me IDENTIFICATION that I am no longer subject to backup withholding; and NUMBER (TIN) (3) I am a U.S. person (including a U.S. resident alien). -------------------------------------------------------------------------------- CERTIFICATION INSTRUCTIONS -- You must cross out item (2) PART 3 -- in Part 2 above if you have been notified by the IRS that Awaiting TIN [ ] you are subject to backup withholding because you have failed to report all interests and dividends on your tax return.
