ICSL will pay the expenses incurred by ICSL in connection with the registration of the Shares, including all registration and filing fees (including all expenses incident to filing with the National Association of Securities Dealers, Inc.), printing expenses, fees and disbursements of ICSL's counsel and independent certified public accountant, and the expense of qualifying such Shares under state blue sky laws, if any. However, all underwriting expenses incurred by the Debenture Holders (if any), including discounts and commissions, shall be borne by such Debenture Holders. The Debenture Holders may be required to provide information concerning the Debenture Holders necessary to complete the Registration Statement, and accordingly, as set forth in the Letter of Transmittal, the Debenture Holders agree to complete and return any documents (including questionnaires) necessary to enable ICSL to complete the Registration Statement. ICSL will pay all stock transfer taxes, if any, payable on the issuance of the Shares pursuant to the Offer; provided, however, that if issuance of the Shares is to be made to any person other than the Debenture Holder, the Debenture Holder will be responsible for such taxes. FEDERAL INCOME TAX BACKUP WITHHOLDING. To prevent federal income tax backup withholding equal to 31% of the gross cash payments in lieu of fractional shares made pursuant to the Offer, each Debenture Holder who does not otherwise establish an exemption from such withholding must notify ICSL of such shareholder's correct taxpayer identification number (which in the case of an individual is their social security number), or certify that such taxpayer is awaiting a taxpayer identification number, and provide certain other information by completing the enclosed Substitute Form W-9 (see the enclosed Instruction Letter). ICSL MAY BE REQUIRED TO WITHHOLD AND REMIT TO THE INTERNAL REVENUE SERVICE (THE "IRS"), 31% OF THE GROSS PROCEEDS PAID TO ANY TENDERING DEBENTURE HOLDER WHO FAILS TO COMPLETE FULLY AND SIGN THE SUBSTITUTE FORM W-9 INCLUDED WITH THIS LETTER. CONDITIONS OF THE OFFER NO PARTIAL PURCHASES. Intelect and ICSL will not accept a tender of a portion of a Debenture. Therefore, if a Debenture Holder tenders his or her Debenture, they must tender all of their Debenture in order for there to be a valid tender and in order for them to receive the Shares. WITHDRAWAL OF OFFER. The Offer is contingent on Intelect and ICSL receiving all of the Debentures, together with the Letters of Transmittal and Releases executed by the Debenture Holders (the "Required Amount"). Intelect and ICSL reserve the right to withdraw this Offer if less than the Required Amount is tendered, or if, in Intelect's or ICSL's sole discretion, it would be inadvisable to proceed with the Offer (including, without limitation, if the filing of the Registration Statement would materially and adversely affect the business or prospects of ICSL or Intelect in view of the disclosures that may be required). In such case, the Debentures, the Letters of Transmittal, and the Releases will be immediately returned to the respective Debenture Holders. INTELECT, INC. /s/ Herman M.
