Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1.         Interest.  Trans Union LLC, a Delaware limited liability company (“Trans Union LLC”) and TransUnion Financing Corporation, a Delaware corporation (“Co-Issuer” and, together with Trans Union LLC, the “Issuers”), promises to pay interest on the principal amount of this Note at 11 ³/8% per annum from                     , 2011 until maturity. The Issuers will pay interest semi-annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided, that the first Interest Payment Date shall be                      15, 2011. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the interest rate on the Notes; they shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the interest rate on the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

2.         Method of Payment.  The Issuers will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on June 1 or December 1 (whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, provided, that payment by wire transfer of immediately available funds will be required with respect to principal of, and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuers or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

3.         Paying Agent and Registrar.  Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers may change any Paying Agent or Registrar without notice to the Holders. The Issuers or any of Trans Union LLC’s Subsidiaries may act in any such capacity.

4.         Indenture.  The Issuers issued the Notes under an Indenture, dated as of June 15, 2010 (the “Indenture”), among Trans Union LLC, TransUnion Financing Corporation, the Guarantors named therein and the Trustee. This Note is one of a duly authorized issue of notes of the Issuers designated as the 11 ³/8 % Senior Notes due 2018. The Issuers shall be entitled to issue Additional Notes pursuant to Section 2.01 and 4.09 of the Indenture. The Notes (the “Notes”) and any Additional Notes will be separate series of Notes, but shall be treated as a single class of securities under the Indenture, unless otherwise specified in the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms.

redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for redemption.

(a)         Upon the occurrence of a Change of Control, the Issuers shall make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon, if any, to the date of purchase (the “Change of Control Payment”).

To the extent that the aggregate amount of Notes (including any Additional Notes) and such Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuers may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Notes or the Pari Passu Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Pari Passu Indebtedness tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Issuers prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

The Issuers need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuers need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

10.         Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

11.         Amendment, Supplement and Waiver. The Indenture, the Subsidiary Guarantees or the Notes may be amended or supplemented as provided in the Indenture.

12.         Defaults and Remedies. The Events of Default relating to the Notes are defined in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the

- 7 -

Holders of at least 25% in principal amount of the then outstanding Notes may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the Note Guarantees except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if any, or interest on, any of the Notes held by a non-consenting Holder. The Issuers and each Note Guarantor (to the extent that such Note Guarantor is so required under the Trust Indenture Act) is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuers are required within five (5) Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default and what action the Issuers proposes to take with respect thereto.

13.         Authentication. This Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee.

14.         Governing Law. The laws of the State of New York shall govern and be used to construe the Indenture, the Notes and the Guarantees, but without giving effect to applicable principles of conflicts of law to the extent that application of laws of another jurisdiction would be required thereby.

15.         CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

The Issuers will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to the Issuers at the following address:
