The undersigned understands that the Purchaser reserves the right to transfer or assign, in whole or from time to time in part, to one or more of its affiliates the right to purchase all or any portion of Shares tendered pursuant to the Offer. The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of May 16, 2001 as amended on June 27, 2001, July 12, 2001 and July 24, 2001, by and among Parent, the Purchaser and DRAI, as it may be amended, supplemented or restated from time to time in accordance with the terms thereof. Upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms of any such extension or amendment), and subject to, and effective upon, acceptance for payment by the Purchaser of Shares tendered herewith, in accordance with the terms of the Offer, the undersigned hereby tenders, sells, assigns and transfers to or upon the order of Purchaser all right, title and interest in and to all Shares that are being tendered hereby and all dividends, distributions (including, without limitation, distributions of additional Shares) and rights declared, paid or distributed in respect of those Shares on or after May 16, 2001 (collectively, "Distributions") and irrevocably appoints the Depositary the true and lawful agent and attorney-in-fact of the undersigned with respect to the tendered Shares (and any and all Distributions), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (1) deliver certificates evidencing the tendered Shares (and any and all Distributions), or transfer ownership of the tendered Shares (and any and all Distributions) on the account books maintained by the Book-Entry Transfer Facility, together, in either case, with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser, (2) present the tendered Shares (and any and all Distributions) for transfer on the books of DRAI and (3) receive all benefits and otherwise exercise all rights of beneficial ownership of the tendered Shares (and any and all Distributions), all in accordance with the terms of the Offer. By executing this Letter of Transmittal, the undersigned hereby irrevocably appoints the Purchaser and the designees of the Purchaser as the agents, attorneys-in-fact and proxies of the undersigned, each with full power of substitution, to vote in such manner as such agent, attorney and proxy or his, her or its substitute will, in his, her or its sole discretion, deem proper and otherwise act (by written consent or otherwise) with respect to all tendered Shares which have been accepted for payment by the Purchaser prior to the time of such vote or other action and all Shares and other securities issued in Distributions in respect of the tendered Shares, which the undersigned is entitled to vote at any meeting of shareholders of DRAI (whether annual or special and whether or not an adjourned or postponed meeting) or consent in lieu of any such meeting or otherwise. This proxy and power of attorney is coupled with an interest in the tendered Shares, is irrevocable and is granted in consideration of, and is effective upon, the acceptance for payment of the tendered Shares by the Purchaser in accordance with the terms of the Offer. Acceptance for payment will revoke all other proxies and powers of attorney granted by the undersigned at any time with respect to the tendered Shares (and all Shares and other securities issued in Distributions in respect of the tendered Shares), and no subsequent proxies, powers of attorney, consents or revocations may be given by the undersigned with respect thereto (and if given will not be deemed effective). The undersigned understands that, in order for Shares or Distributions to be deemed validly tendered, immediately upon the Purchaser's acceptance of the tendered Shares for payment, the Purchaser must be able to exercise full voting and other rights with respect to the tendered Shares (and any and all Distributions), including, without limitation, voting at any meeting of DRAI's shareholders. 3 The undersigned hereby represents and warrants that (1) the undersigned has full power and authority to tender, sell, assign and transfer Shares tendered hereby (and any and all Distributions) and (2) when the tendered Shares are accepted for payment by the Purchaser, the Purchaser will acquire good, marketable and unencumbered title thereto (and to any and all Distributions), free and clear of all liens, pledges, restrictions, charges, encumbrances or voting agreements, and that none of the tendered Shares (and Distributions) will be subject to any adverse claim. The undersigned, upon request, will execute and deliver all additional documents deemed by the Depositary or the Purchaser to be necessary or desirable to complete the tender, sale, assignment and transfer to the Purchaser of the tendered Shares (and any and all Distributions). In addition, the undersigned will remit and transfer promptly to the Depositary for the account of the Purchaser any and all Distributions in respect of Shares tendered hereby, accompanied by appropriate documentation of transfer, and until receipt of transfer or appropriate assurance of receipt and transfer, the Purchaser will be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire purchase price of the tendered Shares, or deduct from the purchase price, the amount or value of that Distribution as determined by the Purchaser in its sole discretion. No authority herein conferred or agreed to be conferred will be affected by, and all such authority will survive, the death or incapacity of the undersigned. All obligations of the undersigned in this Letter of Transmittal will be binding upon the heirs, executors, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable. The undersigned understands that the valid tender of shares pursuant to any one of the procedures described in "The Tender Offer--Procedures For Accepting Our Offer And Tendering Shares" of the Offer to Purchase and in the Instructions to this Letter of Transmittal will constitute the undersigned's acceptance of the terms and conditions of the Offer. The Purchaser's acceptance of the tendered Shares for payment will constitute a binding agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms or conditions of any such extension or amendment).

If any tendered Shares are held of record by two or more persons, all of those named persons must sign this Letter of Transmittal. If any tendered Shares are registered in different names, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of those tendered shares. If this Letter of Transmittal is signed by the record holder(s) of tendered Shares, no endorsements of certificates or separate stock powers are required, unless payment is to be made to, or certificates evidencing Shares not tendered or not accepted for payment are to be issued in the name of, a person other than the record holder(s). If the Letter of Transmittal is signed by a person other than the record holder(s) of the certificate(s) evidencing Shares tendered, the tendered certificate(s) must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the record holder(s) appear(s) on the certificate(s).

Stock Tendered" on the reverse of this Letter of Transmittal, the appropriate boxes on this Letter of Transmittal must be completed. Any shareholder(s) delivering Shares by book-entry transfer may request that Shares not purchased be credited to such account maintained at the Book-Entry Transfer Facility as such shareholder(s) may designate in the box entitled "Special Payment Instructions." If no such instructions are given, any such Shares not purchased will be returned by crediting the account at the Book-Entry Transfer Facility designated above as the account from which such Shares were delivered. 8. QUESTIONS AND REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for assistance may be directed to the Information Agent at the address or telephone number set forth below. Additional copies of the Offer to Purchase, this Letter of Transmittal, the Notice of Guaranteed Delivery and the Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 may be obtained from the Information Agent. 8 9. SUBSTITUTE FORM W-9. Each holder surrendering certificates for payment is required to provide the Depositary with a correct taxpayer identification number ("TIN") on Substitute Form W-9, which is provided under "Important Tax Information," and to indicate whether the holder is subject to backup withholding by checking the appropriate box in part 2 of the form. Each holder must date and sign the Substitute W-9 in the spaces indicated. Failure to provide the information on the form may subject the holder to federal income tax withholding on the purchase price in 2001. 10. LOST OR DESTROYED CERTIFICATES. If any certificate evidencing Shares have been lost, destroyed or stolen, the shareholder should check the appropriate box on the reverse side of the Letter of Transmittal. The Depositary will then instruct such shareholder as to the procedure to be followed in order to replace the certificates. The shareholder may be required to post a surety bond. With respect to Shares evidenced by lost certificates, this Letter of Transmittal and related documents cannot be processed until procedures for replacing lost or destroyed certificates have been followed. The box in Part 3 of the form may be checked if the holder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future. If the box in Part 3 is checked, the Depositary will withhold the required amount of all reportable payments that the holder is otherwise entitled to receive until a TIN is provided to the Depositary. If the holder provides a properly certified TIN within 60 days, the Depositary will refund the withheld amount upon the holder's request. IMPORTANT TAX INFORMATION Under United States federal income tax law, a shareholder's whose tendered shares are accepted for payment is generally required to provide the Depositary (as payer) with the shareholder's correct TIN on Substitute Form W-9. If a shareholder's is an individual, the TIN generally is the shareholder's social security number. If the Depositary is not provided with the correct TIN, the shareholder's may be subject to a penalty imposed by the Internal Revenue Service and payments that are made to the shareholder's with respect to shares purchased pursuant to the Offer may be subject to backup withholding. In addition, if a shareholder's makes a false statement that results in no imposition of backup withholding, and there was no reasonable basis for making such statement, a penalty may also be imposed by the Internal Revenue Service. Certain shareholders (including, among others, corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, that individual must submit a statement (Internal Revenue Service Form W-8), signed under penalties of perjury, attesting to that individual's exempt status. Forms of those statements can be obtained from the Depositary. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions. A tax advisor should be consulted as to that shareholder qualification for exemption from backup withholding and the procedure for obtaining such exemption. If backup withholding applies, the Depositary is required to withhold amounts from any payments made to the stockholder. Backup withholding is not an additional tax. Rather, the federal income 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 if the required information is furnished to the Internal Revenue Service. PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup withholding on payments that are made to a shareholder with respect to Shares purchased in the Offer, each shareholder is required to notify the Depositary of such shareholder's correct TIN by completing the form below certifying that (a) the TIN provided on Substitute Form W-9 is correct (or that such shareholder is awaiting a TIN), and (b)(i) that shareholder has not been notified by the Internal Revenue Service that he, she or it is subject to backup withholding as a result of a failure to report all interest or dividends or (ii) the Internal Revenue Service has notified the shareholder that the shareholder is no longer subject to backup withholding. 9 WHAT NUMBER TO GIVE THE DEPOSITARY Each shareholder is required to give the Depositary the TIN (e.g., social security number or employer identification number) of the record holder of tendered Shares. If Shares are in more than one name or are not in the name of the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional guidance on which number to report. If the holder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, the box in Part 3 of the Substitute W-9 should be checked. If the box in Part 3 is checked, the Depositary will withhold the required amount of all reportable payments that the holder is otherwise entitled to receive until a TIN is provided to the Depositary. If the holder provides a properly certified TIN within 60 days, the Depositary will refund the withheld taxes upon the holder's request. IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE THEREOF) TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE, OR THE EXPIRATION OF ANY SUBSEQUENT OFFERING PERIOD, AND EITHER CERTIFICATES FOR TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE EXPIRATION DATE, OR THE TENDERING SHAREHOLDERS MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY. 10 - -------------------------------------------------------------------------------------------------------------------- SUBSTITUTE PART 1--PLEASE PROVIDE YOUR TAXPAYER FORM W-9 IDENTIFICATION NUMBER IN THE BOX AT ------------------- RIGHT AND CERTIFY BY SIGNING AND DATING Social Security Number BELOW.
