| Re: | Consulting Agreement

Dear Bobby:

The Board of Directors (the “Board”) of TransUnion Holding Company, Inc., a Delaware corporation (the “Company”), is pleased that you have agreed to provide advice and guidance to the Board and its new President/Chief Executive Officer (the “New CEO”) with respect to the transition of duties from you (as the former President/Chief Executive Officer of the Company) to the New CEO, and the development and pursuit of organic and inorganic strategic business opportunities that are being, or may be, pursued by the Company. To that end, we are extending to you an offer to be a consultant to the Company and, subject to the approval of the shareholders of the Company, a member of the Board (and selected subsidiaries thereof) on the terms and conditions set forth in this letter agreement (this “Agreement”). Capitalized terms used herein and not otherwise defined have the meanings ascribed thereto in Section 11 hereof.

1. Term. The term of this Agreement shall be the period beginning on January 1, 2013 and ending on December 31, 2013 (the “Term”). Thereafter, as of the date the Term (as it may be extended from time to time under this Section 1) would otherwise end, the Term will be automatically extended for twelve (12) months, unless one party to this Agreement provides notice of non-renewal at least sixty (60) days before the day that would be the last day of this Agreement in the absence of such renewal.

Notwithstanding the foregoing however, the Term may be reduced in the following events:

(a) You understand and agree that your appointment and election as a member of the Board is at the will of the shareholders of the Company. The Sponsors, as the majority shareholders of the Company, may determine, in their sole discretion, not to nominate or vote their shares for your election to the Board. In the event you are not a member of the Board you may, at your option at any time after such an event occurs, with ten (10) days advance written notice to the Company, terminate this Agreement; provided that, following any such termination, the covenants contained in Sections 7 and 8 hereof shall remain in effect in accordance with their terms.

(b) Due to the personal nature of the performance of the Consulting Services, this Agreement shall (a) automatically terminate, without further action by either party, immediately upon your death and (b) be immediately terminable by the Company upon your disability. As used herein, “disability” shall mean your medically determinable physical or mental impairment which prevents or materially and adversely affects your ability to perform the Consulting Services and which is reasonably anticipated to continue for thirty (30) days or more.

2. Engagement. The Company engages you, as an independent contractor, to provide the Consulting Services, as defined and described in Section 3 below, on the terms and conditions set forth

herein. All of your obligations under this Agreement shall be performed by you and you may not delegate them. You hereby accept such engagement, and agree to diligently and faithfully execute your duties in providing the Consulting Services. You acknowledge and agree that your role with respect to the Company is that of a consultant and independent contractor only, and as such, you shall not (subject to Section 3(b), in the case of clauses (a), (b) and (c)): (a) be an employee or agent of the Company, nor of the Board, (b) have the authority to take any action on behalf of the Company or the Board, (c) have the authority to bind or make decisions on behalf of the Company or the Board, and (d) as a result of your status or role with the Company pursuant to this Agreement, be entitled to participate in any benefit or welfare plans or programs the Company (or an Affiliate thereof) generally makes available to the associates/employees of the Company (or an Affiliate thereof) in the ordinary course of business.

3. Consulting Services and Board Appointment.

(a) The services to be performed by you under this Agreement (the “Consulting Services”) shall be to assist the New CEO, as reasonably requested by the New CEO, in the transition of duties from you (as the prior President/Chief Executive Officer of the Company) to the New CEO, and, as reasonably requested by a Sponsor Representative or the New CEO, providing advice and consultation to the New CEO and/or the Board with respect to the strategic operating plan of the Company, including recommendations as to how best to implement such plan. In addition, you shall also be available from time-to-time to provide assistance to the Board in connection with a strategic opportunity or transaction being considered by the Company, as a Sponsor Representative may reasonably request. The parties expect that the Consulting Services to be requested and performed by you will require approximately eighteen (18) days of work (based on an 8 hour work day) during a calendar year and the performance of such Consulting Services shall not require that you be physically present at any facility of the Company.

(b) You are expected to be appointed a member of the Board by the Sponsors and, if so appointed, shall be deemed an Independent Director. If appointed, you shall be expected to perform the duties required of a member of the Board and shall be a participant (as a member or observer) on such Committees of the Board as requested by the Sponsors. You shall be expected to attend all board and committee meetings in person (except for unforeseen events or emergencies, or as agreed to with the Sponsor Representatives or the New CEO) and the time required for service on the Board of Directors by you shall be in addition to (not in lieu of) any time spent with respect to providing Consulting Services.

(c) You shall not have an affirmative duty with respect to the financial results of the Company (except as a member of the Board, or a Committee thereof), but shall keep yourself apprised of said results.

(d) Notwithstanding anything herein to the contrary, subject to your compliance with any applicable law, rule or regulation and the terms of this Agreement and the Employment Agreement Restrictions (as defined in Section 9(g) below), you are not precluded from (i) serving on the advisory boards and boards of directors of other corporations (that are not Competitors) or the boards of trade associations and/or charitable organizations, (ii) engaging in charitable activities and community affairs; or (iii) managing your personal investments and affairs.

(e) You acknowledge and agree that you will exercise the highest degree of loyalty and care and that you will act at all times in the best interests of the Company and its reputation. In keeping with these duties, you will make full disclosure to the Board of all business opportunities pertaining to the Company’s business that you become aware of, provided you are not required to breach any confidentiality agreement or fiduciary relationship you may have with another Person.

4. Consulting Services Fee, Board Remuneration and Expenses.

(a) Consulting Services Fee. The Company shall pay an annual consulting fee to you for the Consulting Services (the “Consulting Services Fee”) in the amount of One Hundred Fifty Thousand Dollars ($150,000). The Consulting Services Fee shall be deemed fully earned by you when paid by the Company. The Consulting Services Fee shall be paid on or before January 10 of each calendar year during the Term, commencing on January 10, 2013.

5. Company Resources.

6. Staffing. You shall be provided access to Company personnel and employees, to the extent reasonably necessary, to assist you in the performance of the Consulting Services. Further, the New CEO shall reasonably cooperate and assist you in the performance of the Consulting Services.

7. Restricted Covenants.

(a) You acknowledge and agree that the Company has expended and will expend substantial time, effort and resources in developing and maintaining its Confidential Information, as that phrase is defined in the Confidentiality Agreement which is attached as Exhibit A hereto (the “Confidentiality Agreement”) and which is fully incorporated herein. You therefore agree that, contemporaneously with your execution of this Agreement, you also will execute the Confidentiality Agreement and shall comply with all the terms and conditions thereof.

(b) You covenant and agree that during the Term and for a period of twelve (12) months thereafter (the “Non-Compete Period”), you shall not, except as expressly permitted by this Agreement, directly or indirectly own an interest in, operate, join, control, advise, work for, consult to, have a financial interest which provides any control of, or participate in, any Competitor or Significant Operation. This covenant does not prohibit: (i) your mere ownership of less than one percent (1%) of the outstanding stock of any publicly-traded corporation as long as you do not actually control such corporation, and (ii) subject to your compliance with the Confidentiality Agreement and the Employment Agreement Restrictions, your consultation with, and advice to, any Person with respect to any strategic operating plan, investment or transaction to be considered by that Person, provided that in connection with such consultation or advice such Person does not intend to become a Significant Operation or the managing or controlling entity of a Competitor or a Significant Operation.

(c) You covenant and agree that, at all times during the Non-Compete Period, you shall not, except as expressly permitted by this Agreement, directly or indirectly, on your own behalf or on behalf of any other Person, contact, solicit, induce or recruit any Customer to acquire any Competitive Product or Service from any Person other than the Company or its Affiliates.

(d) You covenant and agree that, at all times during the Non-Compete Period, you shall not receive commissions, agency fees, or compensation of any kind directly based on a Customers’ agreement to use any Competitive Product or Service from any Person other than the Company or its Affiliates. As long as you are and remain in compliance with the provisions of the Confidentiality Agreement and the Employment Agreement Restrictions and comply with any applicable law, rule or regulation, this provision shall not restrict or prohibit you from receiving director fees, consulting fees, salary, bonus or benefits (i) as an independent outside director of any Person who offers a Competitive Product or Service, provided, such Person is not a Competitor, or (ii) as a consultant, officer or director of a Customer who may, from time-to-time, consider the use of a Competitive Product or Service.

(e) You agree that the Company has invested and will invest substantial time and effort in acquiring and maintaining its workforce. Accordingly, you agree that at all times during the Term and for twenty-four (24) months thereafter (the “Non-Solicit Period”), you shall not, nor cause any other Person to, (i) hire away any individual who was employed by the Company or any Affiliate at any time during the Non-Solicit Period, or (ii) directly or indirectly, entice, solicit or seek to induce or influence any such individual to leave their employment with the Company or an Affiliate. Notwithstanding the foregoing, the restrictions set forth in this Section 7(e) shall cease to apply with respect to any individual (other than you) upon such individual’s ceasing to be employed by the Company or any Affiliate for a period of six (6) consecutive months.

Siddharth N. Mehta

(f) You covenant and agree that, at all times during the Non-Compete Period, you shall not, individually or jointly with any Person, except as expressly permitted by this Agreement, divert or attempt to divert or take advantage of or attempt to take advantage of any actual or potential business or opportunities of the Company or any Affiliate, of which you became aware as the result of providing the Consulting Services or as a member of the Board.

(g) You acknowledge that should you violate any of the covenants contained in Section 7 hereof (collectively, the “Restrictive Covenants”), it will be difficult to determine the resulting damages to the Company and its Affiliates and, in addition to any other remedies the Company and its Affiliates may have, the Company and its Affiliates shall be entitled to temporary injunctive relief without being required to post a bond and permanent injunctive relief without the necessity of proving actual damage. The Company may elect to seek additional remedies at its sole discretion on a case-by-case basis. Failure to seek any or all remedies in one case shall not restrict the Company from seeking any remedies in another situation. Such action by the Company shall not constitute a waiver of any of its rights.

(h) It is the parties’ intent that each of the Restrictive Covenants be read and interpreted with every reasonable inference given to its enforceability. However, it is also the parties’ intent that if any term, provision or condition of the Restrictive Covenants is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the provisions thereof shall remain in full force and effect and shall in no way be affected, impaired or invalidated. Finally, it is also the parties’ intent that if a court should determine any of the Restrictive Covenants are unenforceable because of over-breadth, then the court shall modify said covenant so as to make it reasonable and enforceable under the prevailing circumstances.

(i) In the event of any breach by you of any Restrictive Covenant, the running of the period of restriction shall be automatically tolled and suspended for the duration of such breach, and shall automatically recommence when such breach is remedied in order that the Company shall receive the full benefit of your compliance with each of the Restrictive Covenants.

(j) You agree that the Restrictive Covenants shall be enforced independently of any other obligations between the Company, on the one hand, and you, on the other (other than the Company’s obligation to make payments hereunder), including without limitation the Employment Agreement Restrictions, and that the existence of any other claim or defense shall not affect the enforceability of the Restrictive Covenants or the remedies provided herein.

8. Promise Not to Disparage. In further consideration for this Agreement, the Sponsors and the members of the Company’s management agree not to disparage you to any Person, and you agree not to disparage the Sponsors, the Company or any of its Affiliates or any of their respective products or services to any Person, and/or not to communicate, either in writing or orally, directly or indirectly, any statement that bears negatively on the Sponsors or the Company’s or any of its Affiliates’ reputation, services, products, principals, customers, policies, adherence to law, shareholders, officers, directors, officials, executives, employees, agents, representatives, business or other legitimate interests.

9. Prior Agreements. Except as set forth herein, effective on January 1, 2013 this Agreement shall supersede and replace all prior agreements, arrangements or plans specifically relating to you that were entered into prior to the date hereof between the Company or any of its Affiliates and you, including, without limitation, that certain Employment Agreement dated October 3, 2007, as amended as of December 6, 2012 (the “Employment Agreement”) (other than the Employment Agreement Restrictions contained therein).

The Consultant agrees and covenants that, during the Restricted Period (as defined in the Consulting Agreement) and thereafter, the Consultant will not, directly or indirectly, disclose to any Person (as defined in the Consulting Agreement) or use for his own benefit or for the benefit of others, any Confidential Information, without prior written authorization of the Company; provided, however, (i) the Consultant may disclose any such Confidential Information as may be reasonably required to perform the Consulting Services (as defined in the Consulting Agreement), and (ii) the Consultant may disclose any such Confidential Information compelled to be disclosed by subpoena
