Ladies and Gentlemen:

IAC/InterActiveCorp, a Delaware corporation (“IAC”) has, pursuant to an Indenture, dated as of December 16, 2002 (the “IAC Notes Indenture”), among IAC (formerly known as USA Interactive), as Issuer, USANi LLC, as Guarantor, and The Bank of New York (as successor to JPMorgan Chase Bank), as Trustee (the “Trustee”) issued $750 million aggregate principal amount of 7% Senior Notes due 2013 (the “IAC Notes”), of which $750 million aggregate principal amount is currently outstanding.  IAC has commenced a tender offer to purchase any and all of the outstanding IAC Notes on the terms and subject to the conditions set forth in the Offer to Purchase and Consent Solicitation Statement dated June 11, 2008 and the related Letter of Transmittal and Consent, which, as amended through the date hereof, together constitute the “Offer,” and in connection therewith is soliciting consents from the holders of the IAC Notes to certain proposed amendments to the IAC Notes Indenture and the IAC Notes as set forth in the Offer (the “Proposed Amendments”).

The Offer and the Exchange (as defined herein) are being made in connection with a plan to separate IAC into up to five publicly traded companies (the “Separation”) as described in a preliminary Information Statement (as it may be amended, the “Information Statement”) attached as Exhibit 99.1 to the Registration Statement on Form 10 of Interval Leisure Group, Inc., a Delaware corporation and wholly-owned subsidiary of IAC (“Interval Spinco”), filed with the Securities and Exchange Commission on June 26, 2008.  Capitalized terms used herein without definition have the meanings ascribed to such terms in those Sections of the Preliminary Offering Memorandum, dated July 7, 2008, as supplemented by the Supplement dated July 11, 2008 (the “Offering Memorandum”), of Interval Acquisition Corp., a Delaware corporation and wholly owned subsidiary of IAC which, at the time of the pro rata distribution of Interval Spinco common stock to holders of IAC common stock and Class B common stock (the “Spinoff”), will be a wholly owned subsidiary of Interval Spinco (“Interval”), set forth on Schedule 1 hereto (including the “Additional Disclosure” set forth in Schedule 1, the “Incorporated OM Sections”), which Incorporated OM Sections are incorporated herein by reference.

IAC proposes, in connection with the Spinoff, to effect with the Noteholders identified as “Exchanging Noteholders” on the signature pages hereto (the “Exchanging Noteholders”) an exchange of $300,000,000 aggregate principal amount of new 9.5% Senior Notes due 2016 (the “Interval Senior Notes”) to be issued by Interval to IAC by way of a distribution prior to the Spinoff for IAC Notes held by the Exchanging Noteholders on the terms and subject to the conditions set forth herein (the “Exchange”).  The terms of the Interval Senior Notes will be as described in the Section of the Offering Memorandum entitled “Description of Notes” with such changes as are set forth on Schedule 2 hereto.  The indenture under which the Interval Senior Notes will be issued shall reflect such terms of the Interval Senior Notes, and shall otherwise include such additional administrative and other provisions as are consistent with those included in the indenture under which the senior notes of HSN, Inc. and/or Ticketmaster shall be issued in connection with the Separation (subject to Schedule 2 hereto), with such administrative, technical, conforming or non-material modifications as are appropriate to reflect the differences in the manner of issuance and offering of the Interval Senior Notes.

In addition, it is proposed that each of the Noteholders identified as “Supporting Noteholders” on the signature pages hereto (the “Supporting Noteholders”) give its consent to the Proposed Amendments as set forth herein.

1.          Agreement of the Parties.

Each of IAC, Interval and the Exchanging Noteholders hereby severally confirms its agreement concerning the Exchange subject to the terms hereof.

Upon Closing, the Interval Senior Notes will be exchanged by IAC for IAC Notes held by the Exchanging Noteholders without being registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon an exemption therefrom.  Each of the Exchanging Noteholders hereby acknowledges that it has received a copy of the Offering Memorandum, has been given full opportunity to ask questions of and to receive answers from representatives of Interval concerning the terms and conditions of the investment and the business of Interval and such other information as it desires in order to evaluate an investment in the Interval Senior Notes, and all such questions have been answered to the full satisfaction of such Exchanging Noteholder.

2.          Nature of Exchange.  IAC, Interval and the Noteholders parties hereto acknowledge and agree that the issuance of the Interval Senior Notes to IAC and the Exchange hereunder, together with the Offer as contemplated by this Agreement to be amended, are occurring in connection with the Spinoff and are intended to give rise to a succession event (with Interval as the sole successor to IAC) for credit derivatives purposes.  For the avoidance of doubt, the failure to give rise to a succession event shall not constitute a breach of this Agreement by IAC or Interval.

3.          Exchange of the IAC Notes for Interval Senior Notes.

(a)   Subject to the terms and conditions set forth herein (including the provisions of Section 6(b) and (c)), each Exchanging Noteholder agrees to exchange with IAC, and IAC agrees to exchange with each Exchanging Noteholder, for each $1,000 principal amount of IAC Notes

2

set forth opposite the name of such Exchanging Noteholder under the heading “Exchanging Noteholder” on the schedule delivered to IAC on behalf of each of the Noteholders in connection with the execution of this Agreement (the “Disclosure Schedule”) and to be exchanged hereunder in the Exchange, (i) a principal amount of Interval Senior Notes equal to the Tender Offer Consideration (as defined in the Amended Offer (as defined below)) and (ii) an amount in cash equal to (x) $30.00 (as a fee for the consent given pursuant to Section 5 hereof) plus (y) Accrued Interest (as defined in the Amended Offer).

(b)   Each Exchanging Noteholder severally represents and warrants to IAC and Interval that it (or, if it is an investment advisor or manager for a beneficial owner or owners of IAC Notes, such beneficial owner or owners), (i) is a Qualified Institutional Buyer as defined in Rule 144A under the Securities Act, (ii) is acquiring the Interval Senior Notes to be exchanged for IAC Notes hereunder for its own account, for investment, and not with a view to or for sale in connection with any distribution thereof in violation of the registration provisions of the Securities Act or the rules and regulations promulgated thereunder, (iii) is aware that it must bear the economic risk of such investment for an indefinite period of time since the statutory basis for exemption from registration under the Securities Act would not be present if such representation meant merely that the present intention of the Exchanging Noteholder is to hold the Interval Senior Notes for a deferred sale or for any fixed period in the future, and (iv) can afford to bear such economic risk and can afford to suffer the complete loss of its investment hereunder. Each Exchanging Noteholder acknowledges that the Interval Senior Notes are “restricted securities” under the federal securities laws, have not been registered under the Securities Act or any state securities or “blue sky” laws and may not be sold except pursuant to an effective registration statement thereunder or an exemption from registration under the Securities Act and applicable state securities laws.  Each Exchanging Noteholder further acknowledges that the Interval Senior Notes shall include the restrictive legend set forth below:

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION.  NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.”

(4)      Neither the Exchange nor the consummation of any other transaction contemplated herein nor the fulfillment of the terms hereof shall result in a material breach of any of the terms and provisions of, or constitute a material default under, any indenture, mortgage, deed of trust or other agreement or instrument to which such Noteholder is a party or by which it is bound, or such Noteholder’s Certificate of Incorporation or By-Laws or other organizational documents, or, to the best of its knowledge, any order, rule or regulation applicable to such Noteholder of any court, Federal or state regulatory body, administrative agency or other governmental body having jurisdiction over such Noteholder or its properties.

4.          Certain Covenants of IAC and Interval.

(a)   IAC agrees, as promptly as reasonably practicable following the date hereof, and in any case within five business days hereof, (i) to amend the Offer as set forth on Schedule 3 hereto (as so amended, and as it may be further amended in a manner not inconsistent with Schedule 3 and the provisions of this Agreement, the “Amended Offer”) and (ii) to issue a press release reflecting the amended terms of the Amended Offer and that the Amended Offer is being made, inter alia, in connection with the Spinoff and the Exchange which are intended to give rise to a succession event (with Interval as the sole successor to IAC) for credit derivatives purposes.  IAC further agrees that (x) the formula for the “Total Consideration” (as defined in the Amended Offer) may not be amended in a manner that would cause a reduction in the Total Consideration, (y) the Amended Offer shall not be amended in a manner that would permit the Amended Offer to be consummated at a time other than immediately after the Spinoff and simultaneously with the Closing and (z) IAC shall not withdraw the Amended Offer except in connection with a termination of this Agreement pursuant to Section 14(g).

(b)  Prior to the consummation of the Exchange, Interval shall enter into a registration rights agreement with the Exchanging Noteholders for the benefit of the Exchanging Noteholders (and their transferees), which shall include provisions, in addition to the other provisions described in this Section 4(b), that obligate Interval to prepare and file a “shelf” registration statement with respect to the Interval Senior Notes with the SEC within 45 days after consummation of the Exchange and to make all reasonable efforts to have such registration statement declared effective as promptly as practicable thereafter (and in any event within 90 days after filing) and to maintain the effectiveness of such registration statement until the earlier of (i) such time as all the Interval Senior Notes are freely tradeable without restriction under the Securities Act and (ii) such time as all Interval Senior Notes have been sold pursuant to such shelf registration statement.  Such registration rights agreement shall provide that, in lieu of such shelf registration, if permitted by the SEC, Interval may effect a registered exchange offer with respect to the Interval Senior Notes during the same time period described in the previous sentence.  Such registration rights agreement shall have other provisions customary for a registration rights agreement that provides for a resale shelf registration statement.  If IAC, Interval and the Exchanging Noteholders cannot agree on what constitutes customary provisions

6

for a registration rights agreement that provides for a resale shelf registration statement consistent with the foregoing prior to the consummation of the Exchange, the Exchange shall be consummated and independent counsel mutually acceptable to Interval and the Exchanging Noteholders shall determine the terms of the registration rights agreement promptly following the Spinoff.  The determination by such counsel shall be final and binding on Interval and the Exchanging Noteholders.

(c)  Interval and IAC shall include in the Information Statement and the separation and distribution agreement relating to the Spinoff statements to the effect that the issuance of the Interval Senior Notes to IAC and the Exchange hereunder, together with the Amended Offer, are in connection with the Spinoff and are intended to give rise to a succession event (with Interval as the sole successor to IAC) for credit derivatives purposes.  Each of IAC and Interval agrees with the Noteholders that it shall not include any statements in any disclosure documents relating to the Spinoff filed with the SEC that are materially inconsistent with the statements described in the preceding sentence.

(d)           In the Exchange, IAC will assign to the Exchanging Noteholders all its rights arising out of or in respect of the Interval Senior Notes, and the Exchanging Noteholders will assign to IAC all their respective rights arising out of or in respect of the IAC Notes being exchanged in the Exchange.

IAC, Interval and the Noteholders, by notice to the other, may designate additional or different addresses for subsequent notices or communications by notice given in accordance with the provisions of this Section 10.

11.        Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

12.        Submission to Jurisdiction; Waiver of Service and Venue.  (a)  Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the U.S. District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such federal court.  Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b)   Each of the parties hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in Section 12(a).  Each of parties hereto hereby irrevocably

13

waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c)   Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.  Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

13.        WAIVER OF RIGHT TO TRIAL BY JURY.  EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHER THEORY.  EACH PARTY HERETO (a) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (b) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION

14.        Miscellaneous

(a)   Counterparts.  This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

(b)   Amendments or Waivers.  (i) No amendment or waiver by Noteholders of any provision of this Agreement, nor any consent or approval to any departure therefrom given by the Noteholders, shall in any event be effective unless the same shall be in writing and signed by Noteholders that, collectively, beneficially own, or are investment advisors or managers for beneficial owners of, at least a majority in aggregate principal amount of the IAC Notes set forth opposite the names of all Noteholders under the heading “Exchanging Noteholder” and/or “Supporting Noteholder” on the Disclosure Schedule (the “Majority Holders”); provided, however, that no amendment or waiver by Noteholders of any provision of this Agreement that results in an adverse modification of (a) the formula for Total Consideration payable in the Amended Offer, (b) the conditions set forth in Sections 7 and 8 of this Agreement, or (c) the material terms of the Interval Senior Notes or of Schedule 2, in any such case shall be effective unless the same shall be in writing and signed by each of the Exchanging Noteholders; and, provided further, that no amendment or waiver by Noteholders of any provision of this Agreement that adversely modifies the consideration to be received by Noteholders in the Amended Offer shall be effective unless the same shall be in writing and signed by each Supporting Noteholder and (ii) no amendment or waiver by IAC or Interval of any provision of this Agreement, nor any consent or approval to any departure therefrom given by either such party, shall in any event be effective unless the same shall be in writing and signed by such party.

(c)   Entire Agreement.   This Agreement, together with the exhibits hereto, contains the entire understanding of the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral or written with respect to such matters.

(d)   Headings.  The headings herein are included for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement

(e)   Previous Agreements.  This Agreement supersedes any other agreement existing between any Noteholder, Interval and IAC concerning the subject matter hereof.

(f)    Further Assurances.  From time to time, at any other party’s request and without further consideration, each party hereto shall execute and deliver such additional documents and take all such further action, including without limitation working with DTC to facilitate the Exchange and taking any actions in respect thereof, as may be reasonably necessary or desirable to effectively carry out the transactions contemplated by this Agreement.  Without limiting the foregoing, the parties hereto hereby agree to promptly take such reasonable steps as reasonably necessary to ensure performance of their respective obligations to exchange the IAC Notes in the Exchange, including, if requested and practicable, the issuance of irrevocable instructions to exchange in the Exchange, conveyance of the IAC Notes to an escrow-type intermediary, or similar arrangements.  Interval shall use commercially reasonable efforts and shall cooperate to permit the Interval Senior Notes to be DTC eligible.

(g)   Termination.  IAC, Interval and the Noteholders shall each have the right to terminate this Agreement prior to the Closing Date if IAC publicly announces the abandonment of the Spinoff.  In the event that any of the conditions set forth in Section 8 hereof shall have become incapable of being fulfilled (other than as a result of a breach of this Agreement by a Noteholder), this Agreement may be terminated by the Majority Holders by delivering a written notice of termination to IAC and Interval.  In the event that any of the conditions set forth in Section 7 hereof shall have become incapable of being fulfilled (other than as a result of a breach of this Agreement by IAC or Interval), this Agreement may be terminated by IAC by delivering a written notice of termination to the Noteholders.

(h)   Remedies.  The parties hereto shall be entitled to equitable relief, including specific performance, in the event of any breach or threatened breach of this Agreement.

(i)    Assignment.  Neither this Agreement nor any right, interest or obligation hereunder may be assigned by any party hereto without the prior written consent of the other parties hereto, and any attempt to do so will be void.

(j)    Initial Press Release.  The parties hereto agree (a) that the initial press release announcing the execution of this Agreement shall be a joint press release by IAC and the Noteholders and (b) to cooperate reasonably with respect to the text of such press release.

If the foregoing is in accordance with your understanding, please indicate your acceptance of this Agreement by signing in the space provided below.
