The Corporations and the LLCs are sometimes referred to collectively herein as the “Delaware Entities” and individually as a “Delaware Entity”.

For purposes of giving the opinions hereinafter set forth, we have examined:

2. A Certificate of Good Standing for each Delaware Entity, dated May 3, 2013, obtained from the Secretary of State of the State of Delaware;

3. A Certified Copy of Resolutions of the Board of Directors of IAC/InterActiveCorp, dated November 28, 2012 (the “IAC/InterActiveCorp Board Resolutions”);

6. The Unanimous Written Consent of the Board of Directors of Tutor.com, Inc., dated April 11, 2013 (the “Tutor.com, Inc. Consent” and, together with the IAC/InterActiveCorp Board Resolutions, the IAC/InterActiveCorp Executive Committee Consent, and the December Omnibus Consent, the “Consents”);

7. The Certificate of Secretary of IAC/InterActiveCorp, dated December 21, 2012 (the “IAC/InterActiveCorp Secretary Certificate”), certifying as to certain factual matters stated therein;

8. The Omnibus Certificate of Secretary of the Guarantors (as such term is defined in the Indenture (defined below)), dated December 21, 2012 (the “Omnibus Secretary Certificate”), certifying as to certain factual matters stated therein;

10. The Omnibus Certificate of Secretary of IAC/InterActiveCorp and the Guarantors (as such term is defined in the Indenture (defined below)), dated May 3, 2013 (the “May Omnibus Secretary Certificate” and, together with the IAC/InterActiveCorp Secretary Certificate, the Omnibus Secretary Certificate, and the Tutor.com, Inc. Secretary Certificate, the “Officer Certificates”), certifying as to certain factual matters stated therein;

11. The Indenture, dated December 21, 2012 (together with the Supplemental Indenture (defined below), the “Indenture”), by and among the Delaware Entities and Computershare Trust Company, N.A.; and

12. The Supplemental Indenture, dated as of April 11, 2013 (the “Supplemental Indenture”), by and among IAC/InterActiveCorp, Tutor.com, Inc., and Computershare Trust Company, N.A., pursuant to which Tutor.com, Inc. became a Guarantor in accordance with the Indenture.

For purposes of this opinion, we have not reviewed any documents other than the documents listed in (1) through (12) above. In particular, we have not reviewed any document (other than the documents listed in (1) through (12) above) that is referred to or incorporated by reference into the documents reviewed by us. We have assumed that there exists no provision in any document that we have not reviewed that is inconsistent with or that would otherwise alter the opinions stated herein.

In addition, we have conducted no independent factual investigation of our own but rather have relied solely on the foregoing documents, the statements and information set forth therein and the additional matters related thereto or assumed therein, all of which we have assumed to be true, complete and accurate.

Based upon the foregoing, and upon an examination of such questions of law of the State of Delaware as we have considered necessary or appropriate, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that:

1. Each Corporation has been duly incorporated and is validly existing and in good standing as a corporation under the General Corporation Law of the State of Delaware, 8 Del. C. § 101, et seq. (the “DGCL”).

2. Each Corporation has the requisite corporate power and authority to execute, deliver and perform its obligations under the Indenture.

3. The execution and delivery by each Corporation of the Indenture, and the performance by such Corporation of its obligations thereunder, have been duly authorized by all necessary corporate action of such Corporation.

4. Each LLC has been duly formed and is validly existing and in good standing as a limited liability company under the Delaware Limited Liability Company Act, 6 Del. C. § 18-101, et seq. (the “LLC Act”).

5. Each LLC has the requisite limited liability company power and authority to execute, deliver and perform its obligations under the Indenture.

6. The execution and delivery by each LLC of the Indenture, and the performance by such LLC of its obligations thereunder, have been duly authorized by all necessary limited liability company action of such LLC.

7. Each of the Delaware Entities has duly executed and delivered the Indenture.

All of the foregoing opinions contained herein are subject to the following assumptions, qualifications, limitations and exceptions:

a. The foregoing opinions are limited to the laws of the State of Delaware presently in effect, excluding the securities, insurance and antitrust provisions thereof. We have not considered and express no opinion on the laws of any other jurisdiction, including, without limitation, United States federal laws and rules and regulations relating thereto. The opinions rendered herein speak only as of the date of this letter, and we undertake no duty to advise you as to any change in law or change in fact occurring after the delivery of this letter that could affect any of the opinions rendered herein

b. Except to the extent expressly set forth in the foregoing opinion, we have assumed (i) the due execution and delivery by each party thereto of each document examined by us, (ii) the due authorization by each party thereto of each document examined by us, (iii) that each of such parties has the full power, authority and legal right to enter into and deliver each

such document and to perform its obligations thereunder, (iv) that each entity that is a party to any of the documents examined by us has been duly incorporated or formed, and is validly existing and, if applicable, in good standing under the laws of its respective jurisdiction of organization, (v) that each of the documents examined by us constitutes a legal, valid and binding agreement of the parties thereto, and is enforceable against the parties thereto in accordance with its terms, and (vi) the legal capacity of any natural persons who are signatories to any of the documents examined by us.

c. We have assumed that all signatures on documents examined by us are genuine, that all documents submitted to us as originals are authentic and that all documents submitted to us as copies conform with the originals.

d. We have assumed that the statements of fact in each of the Consents and in each of the Officer Certificates were true and correct when made and have remained true and correct at all times since such date through and including the date hereof.

e. With respect to each LLC, we have assumed that (i) no event of dissolution, liquidation or termination of the LLC has occurred under the Organizational Documents of such LLC or the LLC Act, and (ii) there has been at all times since the formation of each LLC at least one duly admitted member of such LLC.

We understand that you and the holders of the Notes (as defined below) will rely on this opinion as to the matters of Delaware law addressed herein. In addition, we understand that Wachtell, Lipton, Rosen & Katz (“WLRK”) will also rely on this opinion as to the matters of Delaware law addressed herein in connection with an opinion to be rendered by it on the date hereof relating to the LLCs. In connection with the foregoing, we hereby consent to your, the holders of the Notes (as defined below) and WLRK’s relying on this opinion as to the matters of Delaware law addressed herein. Furthermore, we consent to the filing of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement on Form S-4, relating to the offer to exchange $500,000,000 of 4.75% Senior Notes of IAC/InterActiveCorp due 2022 for $500,000,000 of 4.75% Senior Notes of IAC/InterActiveCorp due 2022 (collectively, the “Notes”), as proposed to be filed by IAC/InterActiveCorp with the Securities and Exchange Commission on or about the date hereof, and to the use of our name in the prospectus forming a part of the Registration Statement under the caption “Legal Matters”. In giving the foregoing consent, we do not thereby admit that we come within the category of persons or entities whose consent is required under Section 7 and the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder.

	Very truly yours,
