Re: Equity Commitment Letter

Ladies and Gentlemen:

Reference is hereby made to that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of October 31, 2018, by and among WC SACD One Parent, Inc., a Delaware corporation (“Parent”), WC SACD One Merger Sub, Inc., a Delaware corporation and a wholly-owned Subsidiary of Parent (“Merger Sub”), and Intersections Inc., a Delaware corporation (the “Company”). Capitalized terms used and not otherwise defined herein have the meanings ascribed to them in the Merger Agreement.

1. Commitment. Subject to the terms and conditions set forth in this letter agreement, the undersigned (“WC SACD One”) hereby agrees to make an equity contribution to Parent immediately prior to the time Parent, Merger Sub and the Company become obligated under the Merger Agreement to effect the consummation of the Offer and the Closing, as applicable, in an aggregate amount equal to the Equity Commitment (as defined below), which amount shall be used by Parent, together with other financial resources of Parent and Merger Sub, including cash, cash equivalents and marketable securities of Parent and Merger Sub on the Closing Date, for the purpose of enabling (a) Parent to cause Merger Sub to accept for payment and pay for any and all Shares validly tendered pursuant to the Offer at the Acceptance Time (the “Offer Amount”), (b) Parent and the Surviving Corporation, as applicable, to make payments due under Sections 3.2, 3.3(a) and 3.4(a) of the Merger Agreement (the “Merger Amount”), and (c) the payment of any fees, costs and expenses required to be paid by Parent or Merger Sub in connection with the transactions contemplated by the Merger Agreement, on the terms and subject to the conditions of the Merger Agreement (the “Expense Amount”). Notwithstanding anything to the contrary in this letter agreement, in no event shall WC SACD One (together with its assigns) be under any obligation under any circumstances to provide an aggregate amount of funds of more than the Equity Commitment to Parent or any other Person. The term “Equity Commitment” means an amount equal to: (i)$73,435,910; provided, however, that the amount of the Equity Commitment (a) shall be reduced by any amount paid by Parent, Merger Sub, WC SACD One, any of the Guarantors or any of their respective Affiliates related to or arising out of the transactions contemplated by the Merger Agreement (including without limitation any payments made under the Limited Guaranty), and (b) shall be reduced by Parent (i) in an amount specified by Parent solely to the extent that, after giving effect to such reduction, for Parent and Merger Sub would still be able to consummate the transactions contemplated by the Merger Agreement in accordance with the terms thereof, and/or (ii) on a dollar-for-dollar basis by the amount of any additional third-party financing obtained by Parent, Merger Sub or any of their respective

wholly-owned subsidiaries at or prior to the Closing; provided, however, that the Equity Commitment shall not be reduced pursuant to this clause (ii) unless and until such third party financing is funded. For the avoidance of doubt, the Equity Commitment is only payable upon the fulfillment of the conditions set forth in Section 2 hereof and for the uses described above and shall not be payable at any other time, under any other circumstances or for any other purpose, and is not a guaranty of collection or the performance of any other obligations of Parent, Merger Sub or any other Person.

2. Funding Conditions. WC SACD One’s obligation to fund all or part of the Equity Commitment is subject in all respects to the terms and conditions of this letter agreement and to (a) with respect to the Offer Amount, (i) the execution and delivery of the Merger Agreement by Parent, Merger Sub and the Company, (ii) the satisfaction in full or valid waiver of all of the Offer Conditions (other than those Offer Conditions that by their nature are to be satisfied at the Acceptance Time, but subject to the concurrent satisfaction or waiver of such Offer Conditions at the Acceptance Time), and (iii) the substantially concurrent acceptance for payment by Merger Sub of all Shares validly tendered and not validly withdrawn pursuant to the Offer, and (b) with respect to the Merger Amount and Expense Amount, (i) the execution and delivery of the Merger Agreement by Parent, Merger Sub and the Company, (ii) the satisfaction or waiver of all of the conditions precedent to Parent’s and Merger Sub’s obligations set forth in Section 7.1 of the Merger Agreement (other than those conditions precedent that by their nature are to be satisfied at the Closing, but subject to the concurrent satisfaction or waiver of such conditions precedent at the Closing), and (iii) the substantially concurrent consummation of the Merger on the terms and subject to the conditions of the Merger Agreement.

3. Representations and Warranties. WC SACD One hereby represents and warrants to Parent, that, (a) upon execution and delivery of the Merger Agreement, this letter agreement will constitute a legal, valid and binding obligation of WC SACD One enforceable against WC SACD One in accordance with its terms (except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar Laws affecting the enforcement of creditors’ rights generally or by general principles of equity); (b) WC SACD One has the requisite corporate power and authority to enter into this letter agreement and to perform its obligations hereunder; (c) the execution, delivery and performance of this letter agreement has been duly and validly authorized by all necessary corporate action and does not contravene, conflict with or result in any violation of any provision of WC SACD One certificate of formation or operating agreement; (d) WC SACD One has sufficient cash or unfunded capital commitments to cause the Equity Commitment to be made available to Parent in order to allow Parent to perform its obligations pursuant to and in accordance with this letter agreement; and (e) all funds necessary for WC SACD One to perform all of its obligations under this letter agreement shall be available (in the form of cash or unfunded capital commitments) to it for so long as this letter agreement shall remain in effect, and no additional internal approval is needed to fulfill WC SACD One’s obligations hereunder.

4. Limited Guaranty. Concurrently with the execution and delivery of this letter agreement and the Merger Agreement, each of WndrCo Holdings, LLC, a Delaware limited liability company, General Catalyst Group IX, L.P., a Delaware limited partnership, GC Entrepreneurs Fund IX, L.P., a Delaware limited partnership, and iSubscribed, Inc., a Delaware corporation (each, a “Guarantor” and collectively, the “Guarantors”) is executing and delivering to the

Company a Limited Guaranty (the “Limited Guaranty”) relating to certain of Parent’s monetary obligations under the Merger Agreement.
